Burglar alarm basic explanation

Control Panel - The brains of the alarm system. This is an independent control center. This unit houses the back-up battery and a digital communicator. We design systems with control panels from various reputable manufacturers as brains. All equipment we use in our designs are approved by internationally recognized agencies, We refuse to install low quality and home-made electronic equipments for obvious reasons.

Remote Arming Station-Also known as keypad, this is the part of the alarm system that will be used every day, this is where the alarm is turned on and off. A four (or more) personal digit code activates the system when you are leaving. When you are staying home, a function allows you to arm the system, but only the perimeter devices and not the indoor motion sensor (if so designed) so you can move freely through your house. It has a 24-hour hold up button (or code) on the keypad. There are also buttons on the key pad that can also be used to call for the fire brigade or medical response through a CMS (Central Monitoring Station. Finally there is a hold up code which you can press; it transmits a silent alarm to your monitoring company in a duress situation.

Magnetic Switches - Door and Window sensors for perimeter protection. This two piece sensor can detect any openings of doors, windows, cabinets, etc. It consists of a reed switch and a magnet. The parts are mounted so that when the door or window is opened, the magnetic field is broken and in turn sends a signal to the control panel setting off the siren and initializing a signal to the monitoring company. The come in various colours and are either surface mount or concealed.

Glass Break Sensor- Glass break protection through glass break detectors are sound sensors that detect the flexing and the intense sound of glass breaking. These devices are the perfect combination with door or window sensors creating a full perimeter system. You may also use an impact or shock sensor serving the same purpose.

Motion Sensor- Interior or Volumetric Motion Detection. The device detects movement and change of environment within their detection pattern. They are used indoors only and are usually placed in an area in which an intruder would likely go if he were to gain entry.

Smoke / Heat Sensor- or Fire detection sensor – Smoke and Heat sensors I strongly suggest that smoke detectors are a 'standard part of your system requirement and not really an option. They should have at least one each area of living, i.e. living room and bedrooms. Heat sensors should be used in the kitchen area because it detects only heat in excess of 135 F, therefore if smoke is present it would set off an unwanted alarm.

Indoor and Out door Alarm Sounder- Audible protection - Siren / This piece of equipment is 100% necessary it can be placed as interior, or outside. This device will sound the alarm upon unlawful entry of a protected area. Usually there is a 3 to 5-minute sound shut-off.

Infrared Beam Sensor or beams, are usually installed outside in an area where we expect trouble to come from. Any body that breaks the invisible beam will set off the alarm before they get to the house. In some cases beams are installed at more than one place as this is a very practical method of keeping burglars away from the premises. The one important thing is to keep the line of sight path of the beam clear to avoid false alarms.

Hold Up Switch- Panic Alarm, these devices can be installed in a fixed location or as wireless component. Personal protection is important to most customers, especially single women. It's very simple; if you press the button on this device it communicates a signal to your control panel which activates a local alarm and a signal to your monitoring company. This Hold Up Switch will operate even if your Alarm System is not switched on. The authorities are dispatched as per agreement with your Central Monitoring Station.

Detailed equipment information
Alarm control panel general features: Alarm control panels are present in both commercial and home security systems. In addition to arming/disarming the control panel can support many other functions. Among the most common are system test, user code changes, schedule control, time setting, reset smoke detectors, silence sounders, view event memory, bypass zones, and relay control (for exterior lights). I will not describe the operation of these features in detail but they will be briefly covered under the appropriate sections that follow.
The important thing to remember is that there are a number of functions that your security control can perform. All controls should be equipped with a rechargeable standby battery to power the system in the event of a power outage. You should have sufficient battery standby to operate the system for the duration of outages you are likely to experience in your area. Most controls can be equipped with enough batteries to power the system for up to 3 hours if needed, although some may require additional charging modules. The amount of batteries needed depends upon the type and amount of devices used and how long you want the system to function without normal electrical power.

Wire or wireless:

Security systems can use wired, wireless, or a combination of wired and wireless devices. The type you use depends upon many factors such as ease of wiring, building construction, timing of the installation, and cost. Wireless systems have a much higher equipment cost and require battery changing every 3 to 5 years but can be installed very quickly. If your major concern is disruption of your home routine, then wireless may be a good option. Wireless is also good when you want to have detectors installed in unattached garages or other buildings on your compound.

Some controls are either wireless or hard-wired but lately many manufacturers have introduced controls that allow both to be used as needed. If you decide to use wireless make sure that the system supervises every transmitter for low battery, transmitter functioning, and whether the door is open or closed. Many low cost wireless systems do not tell you when a battery gets low or if a transmitter has failed completely. Make absolutely sure you buy a proper system if you go for wireless, cheap or home-made systems will just not do, don't play with your safety.

Number of zones:

A zone can be a single point of protection, such as the front door, or a group of points, such as bedroom windows. Point of protection zoning, which is every point is its own zone, can make the system easier to use, repair, and reduce false alarms since the exact location of any problem is immediately identified. Many standard control panels can monitor over 6 - 32 points of protection, more than enough for most installations. How many zones you require depends upon the number of devices you will use and room for future potential additions. Make sure that your control can be expanded to meet your future needs or you may be faced with replacing the control panel when you want to add devices.
Zones can either be supervised or non-supervised. Supervised zones use an end of line resistor (EOL) to maintain a given voltage; if the zone is opened or shorted this voltage will change and activate the control. Unsupervised zones may be normally open or normally closed, normal being the non-alarm state. Zones that are normally open, non-supervised will not alert you to a broken wire in the system. A normally closed, non-supervised system would, but it would not notify you if the wires were accidentally or purposely shorted. For the best security, zones should be supervised with an EOL resistor electronically located at the end of the wire run.

Types of zones:

1. Zones fall into 5 major categories fire, hold-up, medical, burglary, and supervisory. Each type of device has a specific alarm and trouble procedure, for example a fire device will always cause the sounders to activate whether the system is switched on or off and notify the monitoring company, but many control panels allow you to program a custom response to any type of detector.
2. Hold-up zones can be audible or silent (Note: Silent hold-up requires remote monitoring). You may choose either or both. Audible hold-up can be used to 'scare' away prowlers but care must always be exercised when activating hold-up devices since there is no way of predicting the action a prowler may take when he hears the sounders or when the police arrive. Even if your system is monitored, you can also have an audible hold-up that does not send a signal to the monitoring location.
3. Medical alert devices operate basically the same as hold-up devices and have the same options. The only difference is the action that the monitoring company takes when it receives the signals. They come in various shapes and a wireless pendant push button worn around the neck is the most common one.
4. Burglary devices fall into 3 categories, 24 hour (always active), perimeter (doors and windows), and interior (motion or volumetric detectors).
5. Supervisory devices can be water or gas detectors, low or high temperature and the like. Normally these devices are active 24 hours a day and when tripped they do not cause the sounders to sound. They will annunciate at the command center and send a signal to the monitored location.

Arming levels:

There was a time that a security system was either on or off. Today’s control panels allow many levels of arming. The basic ones are AWAY, HOME DELAY, and HOME INSTANT. AWAY arms all perimeter and interior devices and provides an exit/entry delay. It is used when everyone is leaving the premises. HOME DELAY arms only perimeter devices and provides exit/entry delay. It is used if some are leaving and some are still home. HOME INSTANT arms only perimeter devices without any exit/entry delay. It is used when everyone is at home.

Arming devices or Key Pads:

These are the devices that you would use to arm/disarm and control your system. They may be Alphanumeric, that is they display information in text format, LED, which use light emitting diodes to indicate system status, key switch, requires a key to turn the system on or off, or wireless key fobs. Which type you use depends upon several factors such as control type, personal taste, and of course budget.
The alphanumeric are generally the most expensive of the wired devices with key switches being the least expensive. Many controls can support only a limited number of command stations, so make sure that the control you choose has the ability to supervise the number of Key Pads you need. The alphanumeric command stations may be capable of displaying true custom text, such as Jacks door, or may use a library of pre-programmed descriptions like North door. The display may be LCD, liquid crystal display, or fluorescent. The LCD’s are less expensive while the fluorescent are generally brighter and easier to read.
While these devices are the most expensive arming device, I believe that they are worth the money, since they are the only part of the system that you will use every day and it makes sense to have a unit that makes operating the system very simple. They can prompt you for the required data, such as Enter Code when the system is activated and provide a clear visual indication of the system status.
It is very uncommon now days for security systems to be key operated, since a simple key can not perform all of the functions that the control panel can support. They do have applications, the most important of which is the interfacing with a home automation system. The automation controller can provide an output that can be used to arm/disarm the security system. While this is not a true key switch, it appears that way to the control. Wireless arming devices may be 1 way, that is they are only capable of sending a signal, or 2 way. The 2 way devices are more expensive but they do confirm that your command was received and carried out. These devices are necessary when you want to arm/disarm the system from your car or when it would not be possible to run wire to a location that needs a command station.
Most systems limit the functions of wireless command stations so it is important that you have at least 1 wired station as part of your system. Another way of confirming your system is switched on or off is to utilize the “squeak” function. More or less the same sound as when you switch the security alarm from your car on or off. One drawback of this is that the neighbours know also if you switch your alarm and they may not like the sound at night.

Outputs:

All controls have some output to activate at least one sounder but many can also be equipped with relays. These relays can allow you to perform many functions.

User codes and Authority levels:

Most control panels provide multiple user codes. This allows the user to assign each operator of the system their own code, making it easy to remember. The authority levels allow you to control what features/functions each user can perform. You may want your code to control every feature but the codes you give to your employees may only arm/disarm the system. This is also useful if one would like to receive a "user closing and opening report". In case one wants to monitor if a certain person is really coming and going in time or as appointed.

Multiple areas:

It may be desirable to divide your security system into several areas. A multiple area system allows one control to be segregated into a number of areas that can be armed / disarmed individually. This allows you to keep the system active for one area while the rest of the security system is off. If your control has authority levels you can also assign the areas to the individual codes.

Zone bypassing and forced arming:

Sometimes you may want to disconnect or bypass, some of your protection. If you are having a window replaced, you may have to bypass the protection on that zone until your security company can reinstall the sensor or device. Force arming is the arming of a system with one or more zones is still open or in trouble. It is similar to bypassing with one exception. If the troubled zone returns to normal after the system is force armed it can become active. This is helpful if the zone was a motion detector that was not reset when you were arming the system but does reset a minute later.
A variation of bypassing is called swinger shunt. This is a control panel function (not all control panels have this function) that will automatically bypass a zone if it trips more than a preprogrammed number of times. For example if a severe storm should cause a motion detector to continually trip, the control will bypass it after 3 or 4 alarms to prevent additional signals. Once a zone is bypassed in this manner it may remain bypassed until the system is disarmed or some controls will reactivate it, if it remains stable for a period of time, typically 1 hour. This allows the system to maintain the maximum level of protection at all times.

Communication techniques:

If your system is monitored it must be connected to the central monitoring station by some means of communication. The most common used today is called digital communication, using your existing telephone line. When the control needs to send a signal it "seizes" the line, disconnecting your telephones, and calls the central monitoring station. These systems do not require any special telephone lines but have the disadvantage that if your telephone line is out the control cannot communicate.
Your control can be programmed to send a simple test message to the monitoring office every 24 hours to check the integrity of the line. If this signal is not received then the monitoring office knows that something is wrong. It may not detect a burglar cutting the line but it is better than nothing.
You can also connect a telephone line monitor to your telephone line to activate your system if the line fails, providing a local indication of the problem. If additional security is desired you may be able to add cellular telephone, long range radio, derived channel, or one of the special lines that are available from the telephone company in your area. Cellular or SIM line units use the wireless cellular network to provide a path for your control panel to call the monitoring office. As the communicator will call two numbers you could consider to use one land line and one SIM line connection, this way you ensure 24 hr uninterrupted connection.
Long range radio provides a wireless path between your home and the monitoring office. Derived channel is a service offered by some telephone companies that uses your existing telephone line and adds a special tone to the line to detect someone cutting the wires. Unlike cellular or radio this system will not send the alarm to the monitoring office, after the wires are cut; it only tells them that they were cut. In certain areas the telephone company will lease a dedicated line that connects your home to the monitoring office. This approach is the most expensive and has limited applications in home security.

Monitoring companies use special phone lines, computers and trained staff to watch over a home security system and call the appropriate authorities if the alarm goes off. There is a monthly fee for the service. Because quality and experience can vary greatly among monitoring companies, do some homework before choosing one.

Magnetic Contacts:

Magnetic Contacts are the most common devices used in burglary systems. Their purpose is to trigger an alarm whenever a door or window is opened. These devices can be surface mounted or depending on the type of door/window, recessed. In addition to the standard door/window contacts there are a number of specialty contacts for use outside, on safes, or for high security applications. The standard contacts are available, depending on the manufacturer, in a small range of sizes and colors such as brown, white, ivory, or gray. Ask Master Safety Enterprises Ltd. to show you a "cut sheet" or sample of the contacts they are planning to use.
Magnetic contacts consist of 2 parts, a switch which is mounted on the fixed structure (frame) and a magnet which is mounted on the movable door/window. When the magnet is in close proximity to the switch the magnetic field "closes" the switch. Opening the door/window causes the switch to "open". Please note that while most burglary systems trigger an alarm when a zone "opens" (called normally closed), some systems trigger an alarm when a zone "closes or shorts" (called normally open). A normally closed system will trigger an alarm if a detection device trips or a wire breaks. The exception to this is Fire Alarms or a fire dedicated zone in a burglar alarm control panel.
In a Fire system a short is an alarm while an open is a trouble. This is to prevent a broken wire from causing a false fire alarm. In cases where you want to be able to leave a window open a little for ventilation, it may be possible to use 2 magnets and 1 switch. In this configuration the first magnet is mounted in the window closed position and the second is mounted in a location where it will align with the switch when the window is open a few inches, typically 3 or 4 inches. This allows for ventilation but will sound the alarm if the window is fully opened. Please note that an “open” window is an invitation to some people to try to break in.
The alarm system must be disarmed whenever the window is moved between the 2 positions or the alarm will sound. An alternative to this is to use a 2 part "pull-apart-plug" with a small length of wire, or a roller switch. These methods allow you to open and close the window to a pre-set limit without disarming the system. In addition to magnetic contacts there are plunger switches which mount in the frame and the action of closing the door/window pushes the plunger in completing the zone. Deciding which doors/windows should be contacted depends upon the accessibility of the windows and your budget. The best security is achieved by installing contacts on all doors and windows which are accessible. This provides the earliest notification of an intrusion. Window or wall mounted air conditioners may also require protection if they can be easily removed from the opening. The standard method used to protect these units is to install a contact on the unit.

Glass break detection:

• The original method used to protect glass was the application of foil. This metallic tape was adhered to the glass and would break if the glass was broken. While foil is an effective method of protecting glass and has a strong psychological deterrent factor, it is certainly not aesthetically pleasing. Today foil is rarely used, it has been replaced by audio detectors, shock sensors, beam sensors (along the wall of the premises) or motion detectors.
• Audio detectors "listen" for the specific sound pattern generated when glass breaks, while shock sensors "feel" for the vibration of breaking glass. Certain shock sensors can be mounted directly on the glass while others can be mounted on the frame. Generally speaking the glass mounted detectors cause somewhat less false alarms than the frame mounted units, since their sensitivity can be lower than frame mounted units. Mounting directly on the glass does require that a wire be run from the frame to the unit. This can make their choice limited to fixed panes of glass or in areas where appearance is not a primary concern. Audio detectors can be mounted on the frame or in certain cases on the ceiling or wall. Remember that since these units are 'listening' for the sound of breaking glass, anything that can dampen sound waves, such as drapes, curtains, or shutters can affect their performance.
• Audio detectors generally are lowest in cost, since in many cases 1 unit can protect more than 1 window.

Interior protection:

Interior detection consists of installing detection devices within the premises arraigned so that an intruder moving about will sound the alarm. The most common forms of interior detectors are motion detectors, and contacts on specific doors such as bedroom, garage, or basement. Interior detectors enhance the effectiveness of your perimeter contacts and should be considered if you are not completely protecting all exterior doors and windows. Motion detectors can be ultrasonic, microwave, photoelectric eyes, PIR, or dual technology detectors.

The most common in use today are PIR and duals, due to their lower level of false alarm activity. Motion detectors can be surfaced mounted or recessed into the walls. They range in size from 1 inch in diameter, flush mounted (visible section), to 3`X8`X6` surface mounted. If you choose to use motion detectors ask to see the units selected. Also examine the proposed location of each unit to make sure that you will be happy with the final appearance of the system.

• Ultrasonic and microwave detect motion by sending out a high frequency sound wave and listening for the returning frequency. If there is no movement within the area of coverage, the returning frequency will be the same as the one sent out. Just as the frequency of a car’s horn increases as it approaches and decreases as it moves away, any movement within the area of coverage will cause an increase or decrease in the frequency that the units receive. This change, known as the Doppler Shift, is what causes the unit to sound the alarm. While both ultrasonic and microwave use the same principle to detect motion, a microwave uses a much higher frequency and as a result it can detect motion through most walls not made of metal or concrete.
• Photoelectric eyes, also called “Beams” consist of a transmitter, which sends out a beam of light, and a receiver which "sees" this beam. If someone walks through the beam the receiver will sound the alarm. These devices can be surface mounted or recessed, but require a straight line of sight between the transmitter and the receiver. Contrary to many movies, the light source used in toady's PE's can not be seen with the human eye. Most beams have a “double beam” which reduces false alarms from falling leaves or even birds. Also the pulse rate can be adjusted to further the catch performance of people instead of say jumping cats.
• PIR’s detect the infra red energy given off by all objects and will trip if it senses a movement of this energy above a pre-set limit. Since these devices do not emit any energy, they are called Passive Infra Red (PIR) detectors. This quality also allows the unit to be positioned and adjusted to cover a very specific area or part of an area. Some units have a special Pet Alley lens which allows them to be used in areas with pets. This pet alley prevents the PIR from detecting motion close to the floor only, so care must be exercised to insure that any pets can not jump high enough to cause a false alarm.
• Dual detectors usually combine a PIR detector with either an ultrasonic or microwave detector in a single unit. Both of these detectors must trip before an alarm will sound. These units have become popular due to that they can reduce false alarms. Some units have a special Pet Alley lens which allows them to be used in areas with pets.
• Interior door contacts are the least expensive method of providing interior protection. Installing contacts on bedroom, garage, basement, or other inside doors will sound the alarm if someone opens the door with the system fully armed.

If your system will include interior protection make sure that the control has an easy way to arm the system in either an "at Home" or "Away" mode. The home mode is for when there are people inside the house and will not respond to trips from the interior detectors. The Away mode is for when everyone is out and the interior devices are now active. Most controls in use today have this feature built in.

Fire detection:

No security system is complete without some form of fire detection and you should include some of these devices in your system. In addition to installing fire detectors you should have a pre-planned fire escape plan. All members of the household and/ or staff should know the plan and it is advisable to practice it on a periodic basis. The plan should include 2 escape routes from every area in the home, in the event the fire blocks 1, and a meeting place outside the home. You can contact Master Safety Enterprises Ltd. for additional fire safety tips and information.

• Smoke detectors sense the presence of smoke. There are 2 basic types, Ionization, and Photoelectric. Either type will work well in a home system. Some smoke detectors can also have a fixed temperature heat detector built in. Smoke detectors should be located on each floor and by every sleeping area. It is important that all smoke detectors be cleaned annually and tested periodically.
• Fixed temperature heat detectors will sound the alarm when the temperature at the detector reaches a pre-set limit, typically 135 or 200 degrees. These devices are generally used in attics, boiler rooms, or garages.
• Rate of rise heat detectors will sound the alarm if the temperature at the detector increases at a very rapid rate, typically 15 degrees per minute. These units also have a fixed temperature detector included. They can be used in areas where smoke detectors are not suitable such as kitchens, or work shops.
• Pull stations are devices that can be manually activated to signal a fire. If used, they should be mounted by the exits of the house so that they can be triggered as you leave your house during a fire.

Miscellaneous devices:

Panic devices are manually activated units that you can activate if you need immediate assistance. These units can either be silent or activate your sounders. If you desire the silent version than you must have your system monitored. You should bear in mind that activating these units may alert the intruder to your actions, so care must be exercised in their use. Panic devices can be fixed buttons, portable wireless buttons, or a special combination at the keypad push buttons. A variation on the panic device is the Medical Alert. Typically medical alert uses a wireless button that is worn around your neck on a chain and can be activated if needed.
Detectors are also available to detect gas or water leaks or carbon monoxide gas. These units can sound a special alert tone at the keypads, activate the sounders, or send a signal to the Central Monitoring Station. Temperature detectors can alert you to a failure in your heating system before any damage from freezing pipes can occur. As this is highly unlikely in Thailand we employ these sensors for the opposite purpose, detecting faulty freezers etc. This is particularly helpful for homes and retail outfits where lots of valuable food is in the freezer and there is a fault with the electric power supply. Like the gas detectors they can sound a special alert tone at the keypads, activate the sounders, or send a signal to the Central Monitoring Station.
Home & small office access control
There are two main ways to address the access control requirement of homes and small offices. One way is the keycard system which is inserted in the door knob. These coded card door locks usually replace an existing key door lock without major adjustments and are reasonable priced. These systems are card activated by inserting a patented magnetically coded card which "powers" the lock, providing high-tech security without electricity, wiring, batteries, or an expensive computer. Because they do not use electricity, these locks are ideal for both internal and external doors and require virtually no maintenance.
Another way is to go electronic. This may not be desirable for homes for an aesthetic point of view but for offices it is very acceptable. In this case the control system is divided in various parts, a reader, a lock be it magnetic or a door strike, a battery back up and key cards. The mag stripe card is rarely used, now a days the proximity card took over some time ago. Real fancy and higher security devices are the finger print reader and even retina readers but they are more for very high security applications not found in homes and small offices.

Home & small office CCTV
CCTV cameras properly installed at the correct location are not only a deterrent but we may have a description of the possible perpetrators. System range from basically four, eight, sixteen and even thirty two cameras and the views are recorded simultaneously on one Hard Disc, recording duration of up to three weeks is possible with the right programming. Most systems are able to be viewed over the internet if broadband is available at the place of recording. A four camera video security system is a perfect solution for any home or small business owner with a tight budget. Usually they come complete with four Infrared in/outdoor cameras, a 500Gb hard drive, cables and easy installation instructions. The four IR cameras deliver a razor sharp 520 lines of color resolution day or night, and some have a commanding 92 degree field of view . Each of the video security cameras includes their own 20 meter. all-in-one video/power cables which are easy to install. There are many different cameras for different applications, too many to name. Basically we differentiate between hard wired, wireless and IP cameras the latter connects direct to a computer without using a DVR (Digital Video Recorder).

Home & Commercial High Voltage Scurity Fencing

Traditional physical barriers such as fencing, walls and palisades in conjunction with barbed or razor coils are evident at residences and industrial sites throughout Thailand.
It is Master Safety’s opinion that there is nothing to compare with electric fencing when one wishes to ensure that intruders do not enter where they are not wanted. Not only will the intruder be faced with a physical barrier, they will also be exposed to high voltage pulses that WILL deter the most hardened criminal and definitely the opportunist burglar. 
A Master Safety electric fence is a primary security system. An electric fence not only acts as a physical barrier, but also acts as an early warning alarm system. The fence is continuously monitored and will generate an alarm if interfered with or tampered with.  This means it is designed to prevent/detect unwanted people from entering your property. The electric security fence can be connected to an existing or newly installed burglar alarm system so intrusion is also monitored 24/7 if you so require.
There is no doubt; an electric fence is an asset to home owners and businesses alike, offering a highly effective security system / addition.

Video Door phone

Hear and see who’s at the door before answering! Security and Convenience! Protect employees at work or your family at home. Easy to Install. The Video door phone uses the same four wires between stations as an ordinary telephone system. So, it can be wired in new construction, or replace an existing doorbell. The power source is 220AC to 24 Volt DC. When a caller presses the call button on the door station, the caller can speak completely hands free. If it’s dark outside, the automatic illuminator LED's light up the area in front of the door station, up to 20" away. Using the optional External Light control relay, a porch light or other light source can also be automatically turned on. Inside, at the room station, the two-tone electronic chime sounds, and with the Instant-on feature, you can immediately both hear and see who's at the door before picking up the handset to speak.

24Hr. Alarm monitoring

In case your alarm system is activated due to the violation of one or more alarm zones, it will initiate a call through the build in alarm communicator through a telephone line or wireless telephone connection whichever is installed at your premises. We will call you to verify your alarm signal before we dispatch emergency authorities. Or, if you prefer, we can call the authorities immediately without verification from your premises. Then we call your designated contacts until we reach someone to report that authorities have been dispatched. For emergency conditions other than fire or burglary, you have a choice of a dozen alarm response options. When a hospital sends an ambulance to your premises the cost incurred is to be paid by the called direct to the hospital.
If an intruder forces you to call and cancel an alarm, or you suspect someone is on the premises who may be able to hear our verification call to you, use your stress code instead of your pass code. Our monitor tells you that the alarm is canceled, then calls the police and informs them of a stress situation.

If you accidentally trip your alarm, call us with your pass code to cancel the false activation.


FAQ Most common questions

• How does an alarm system work?

An alarm system may be armed in an at-home or away mode. Once the system is activated, each monitored zone has the ability to recognize a violation. Once a zone has been violated, the alarm system then sounds a local alarm and dials the Central Monitoring Station and transmits the message through a telephone line or SIM line. Once the signal is received the alarm system will wait to send another message if another zone is tripped. Entering the code and turning off the system will end the process.

• Can I have my system turned on when I’m at home?

Yes, your system can be designed in any number of ways to accommodate your lifestyle. You can choose from several levels of protection. For example, when you are away from home you can have all sensors activated. When you are at home in the evening, watching TV or making dinner, you can choose to have your door and window sensors activated and your interior motion sensors off. System smoke detectors are always active. We at Master Safety Enterprises Ltd. can help design the system that works best for you.

• I have a battery-operated smoke detector, why would I need one on a security system?

A smoke detector that is part of your system provides more protection than a "stand-alone" detector because it is monitored. When smoke is detected the detector signals an alarm and sends a trouble signal to the control panel which automatically dials your Central Monitoring Station and the operator calls the fire department, this does not happen with a stand alone unit.

• Why do alarm systems take so long to notify the Central Monitoring Station?

An alarm system usually provides a delay period for the user. This delay period allows the user to disarm the system in order to prevent an alarm activation. The delay period can range for example from 30 seconds up to 1 minute. At our Central Monitoring Station we usually don’t delay alarm signals.

• What happens when I press the panic or fire alarm buttons on a key pad?

If you hold down the panic or fire alarm buttons on the touch pad for 2 to 3 seconds until you hear a beep sound, an alarm is transmitted to our Central Monitoring Station, and emergency services are dispatched. An alarm received in this manner cannot be canceled, only by calling the Central Monitoring Station.

• If the power goes off, will my alarm system still work?

Yes, in case of a power loss, the back-up battery will activate to maintain your alarm protection for several hours. In the event your battery is low, a low battery signal will be sent to your security company so you can be notified.

• If I have an emergency, should I call the security company first?

No, if you have an emergency (not a break in), call 911 first. If you are unable to call 911, then depress the panic alarm button on your touch pad, and the Central Monitoring Station will request emergency services.

• Am I responsible for testing my system regularly?

Yes, it is your responsibility to make sure that your system is in good working order. Master Safety Enterprises Ltd. regularly initiates a communications performance test. It’s easy to test your system; just refer to your owners handbook.

• What is a false alarm?

A false alarm is when an "alarm" is generated by the client to the Central Monitoring Station, which is not due to: - An attack (or attempted attack) on a home or alarm system - Activation of the personal attack device (panic button) resulting from assault or threat of assault within the home. - A fire (if you have a smoke detector fitted)

• What cause false alarms?

Sensors can be activated by - Open windows or external doors causing draughts, which move curtains and plants. (only in case of microwave type sensors) - Pets not being confined to designated rooms. (if no pet excluder window on the sensor is installed) - Insects, ants and spiders and also tjintjoks (small lizards) in particular (keep your premises free from insects and rodents) - Electrical or electronic items which can change temperature quickly - Key holders or users who are unfamiliar with your system - Entry to the home or protected area before the system is switched off.

• My alarm went off accidentally, but I quickly put in the code and shut it off.

I expected a call from Master Safety Enterprises Ltd., but no one called. Why not? The system allows a brief period for you to turn off your system before an alarm signal is sent to the Central Monitoring Station. This gives you enough time to cancel the signal and prevent a false alarm. We can see on our site that you used the proper code to switch off your alarm.

• What is electric fencing and how does it work
  
  The electric fence was primarily developed for the restriction of animal movement. In recent years the security industry has improved on it to give a system utilizing wires fitted on insulators and powered by an energizer which is capable of delivering a substantial and most uncomfortable shock..The energizer in simple terms is a transformer that can convert low power to a huge quantity of power to the person touching the wires. The energizer used for this purpose will not allow anyone to be killed as the unit is designed to allow the power to pulsate on/off on a continuous basis. Therefore unlike your power in the house where a possibility exists that you could die if experiencing a shock, the electric fence power switches on and off momentarily and therefore is termed a non-lethal electric fence.

  Energises conform to IEC legislation. This legislation limits the energy output of security units to stop the public from being fatally shocked.

  There is also other controlling legislation such as the minimum installation height permissible and warning sign requirements etc.

Security Tips
(Irrespective if an alarm system is installed or not)
1. Install solid entrance doors
Most burglaries occur through doors and the burglars do not pick the lock, they simply kick the door open. Steel clad doors offer a very high degree of security but make sure that the door frame and edges are also steel. Glass panels in doors or glass sidelights may look great but they can afford they would be burglar with an easy way to open the door. While you have your tools out you should also install a peephole viewer in the door. These little devices allow you to see who is at the door before you open it. Please contact Master Safety Enterprises Ltd. concerning steel security doors, they have a “wood” finish and are very very secure.

2. Install dead-bolt locks
Your door lock may be the only thing that prevents someone from gaining access to your home. If you install a good quality dead-bolt with a 1 inch bolt you are on the road to increasing your home security. Make sure that you use long screws, 3 inches, to secure the latch plate to the door frame. Using screws of that size should reach the studs and dramatically increase the strength of the lock. If your door has glass panes or sidelights, you should consider using a double cylinder lock, since a burglar could break the glass and unlock the door by reaching inside. This type of lock requires a key from both outside and inside. A word of warning, if you use a double cylinder lock keep a key near the inside of the door for use in an emergency such as a fire and make sure that everyone in the home knows where the key is located.

3. Exterior lighting
Burglars do not like attracting attention. A darkened area is an invitation to would be thieves. Exterior lights can be purchased with sensors that will automatically turn them on when it gets dark and off when the sun comes up. You can also use lighting that incorporates a motion sensor so that the light will only come on when someone walks towards your home. In addition to being a good deterrent these lights make your life easier if you come and go at night.

4. Intercoms
Another great project is installing an intercom at the front door. Intercoms provide a safe and convenient means to speak to someone who rings your doorbell, without opening the door. Remember once you open the door it no longer matters how strong the door or lock is, you will be face to face with whoever is there. If desired you can purchase a video-intercom that will not only allow you to talk to, but to see who is at the door. Most of these systems require you to run wire between the inside units and the outdoor station. The exact type of wire will vary by manufacturer so make sure that you purchase the correct wire for your chosen unit.

5. Landscaping
Trimming your shrubs and trees is another way to increase security. Like adding exterior lighting, keeping your landscaping trimmed deprives the burglar with any concealment, and increases the possibility of detection. Make sure that all doors and windows are clearly visible to your neighbors and from the street. This is a job that almost anyone can do with simple inexpensive tools and a little knowledge. Check with your local garden supplier for information on the proper procedures to keep your beautiful landscape from hiding a terrible act. Just a tip, plant Cactus plants under your windows, it is very uninviting for our local burglars who usually wear only plastic flip flops.

6. Mark and Inventory
One of the simplest things that you can do is to take an inventory of all of you valuables recording the make, model, and serial number. You can also mark many appliances with some identification number such as driver’s license or social security number. To mark the number on the appliance you can purchase a hand held engraver or contact your local police department. They will be able to tell you what type of identification to use and may even be able to loan you an engraving tool. Jewelry should be described on your inventory and attach a picture of every piece using a cloth as a background. You can place a ruler in the picture to assist in determining the size of the jewelry. Make two copies of the list. Keep one in a fire resistant box in your home and give the other to a friend for safekeeping. As you add appliances or jewelry, update your copy and make a new copy for your friend. Video tapes can also be used to record your inventory. When you start recording clearly state your name, address, and date of recording. If the recorder has a time and date feature, keep it on so that it will become part of the tape. Carefully describe each item, including serial number as you record it from every angle. As with the paper inventory you should have 2 copies, one of which is stored at another location.

Above all remember to use the locks, intercoms, and lighting you install. They will not help if you become complacent and begin thinking it cannot happen to you. You can make your home burglar proof with a proper electronic burglar alarm system but you can and should take whatever steps you can to make your home less appealing to a burglar to start with.
