Security Glossary

Abort

Discontinues the transmission of an alarm signal, and/or signals the monitoring centre to disregard an alarm signal. This feature allows the system user to reduce false alarms if the system is accidentally tripped.

Absorption

The property of materials such as carpeting, drapes, clothing, acoustic ceilings, weatherstripping, etc., to absorb shock and/or sound waves. It affects the manner in which certain sensors (such as audio discriminatory and/or glass breaks, etc.) can be used or set.

AC Line Noise

Electrical noise of a rapidly alternating or pulsating nature that can "mask" signals received by the panel and/or disrupt panel memory. This problem is dealt with by installing a line choke on the A.C. power supply line.

Access Control

Any means of limiting entry into an area and/or building. A common usage would be a card that controlled access to a parking garage.

Account

(And/or Monitored Account) is a location at which Intercept has installed a security system and is providing monitoring service. The accumulation of accounts is Intercept's sole reason for existence.

Acoustics

How sound travels in a certain area is called the acoustics of a room. It affects how audio discriminatory sensors can be placed in that room.

Active Detector

A detector that transmits energy in order to perform its detection function, (for example, photoelectric beams, ultrasonics, microwaves, etc.), as opposed to passive detectors, such as a motion sensor (which uses infrared). As a general rule, active detectors are not used in wireless systems due to their energy draw .

Alarm

Signal a Panel generates when responding to activation of a sensor

Alarm Screen

A window screen with fine insulated wires, either woven into or sewn onto the screen fabric, and connected in such a way that cutting the screen or removing it, will trip the alarm.

Alarm Signal

A signal sent out by the main control unit, indicating that a sensor has indicated unauthorized activities.

Alignment

The proper aiming of a motion sensor to cover the intended area, while at the same time, paying particular attention to any environmental concerns that could lead to false alarms.

Arm Away

The alarm system reacts to all signals received from sensors that indicate any movement within the protected premises. Usage would be when no one would be at the premises.

Arm Home

The alarm system only reacts to signals received from sensors that are programmed into the system as perimeter protection. It is designed to alert the alarm user to any unauthorized access to the premises, while at the same time allowing free movement inside the premises. Usage in a residential setting would be at night, when everyone is in bed, and no access to the premises is anticipated.

Armed

An alarm system that has been instructed to look for intrusion as well as environmental trips. An example would be an unarmed system that will still respond to a fire alarm, but which would not respond to a motion sensor being tripped.

Audible Alarm

An alarm that makes a noise as well as sending a signal to the monitoring centre, as opposed to a silent alarm. It is Intercept policy to strongly recommend that an audible alarm be installed as the noise forms a deterrent.

Audio Discriminator

A detector that triggers an alarm when it detects a certain type of noise or any noise. The main problem with depending on this type of sensor, is that there is only chance to be right. If the sensor misses the initial noise of the break-in, it does not have a second chance to detect it. Also, in order for this type of detector to work, the area being protected must be violently broken into. Crawling in an open window, or jemmying a lock will not set it off. It is Intercept policy to never recommend exclusive use of this technology in protecting a location.

Back Up Battery

Reserve power source in case of primary (AC) power loss. It is Intercept policy to make a rechargeable battery, a part of every system sold.

Blind Area

In referring to a motion detector, this indicates areas that are blocked out due to physical obstructions located between the motion detector and the whole space. An example would be using a motion detector to protect a garage, and then parking a big truck in front of the sensor.

Burn In

The preliminary operation of an alarm system to help stabilizes its electrical characteristics after manufacture. An example would be when an alarm system is put on a seven (7) day "burn in," or test period before being put "on line."

Bypass (TO)

Overriding the alarm's safety features. With keyfobs there is an audible "buzzing" sound when someone arms the system. When something is open or not checking in, the system can be "bypassed" or "overridden" and armed by pushing the Arm button again quickly. After this is done, the normal beeps should sound. This is not a recommended procedure because if a window or a door is left open, and it then blows shut -- opening it again will cause the system to treat the occurrence as an alarm.

Casement Windows

A type of window that hinges outward and is usually opened with a crank. It is often difficult to mount contact on this type of window especially if customers want a fresh air feature.

CCTV

Closed Circuit Television.

Certified Alarm System

An alarm system that has been certified by Underwriters Laboratories (U.L.), or Underwriters Laboratories Canada (U.L.C.) to meet certain standards depending upon usage. This is a very complicated field.

Check-In

A signal sent from a transmitter to the panel telling the panel the status of the transmitter (for example, if it is opened or closed, whether or not it has a low battery, etc.). The panel listens for each transmitter that has been taught to check-in with it on a regular basis, and if the panel does not receive a check-in signal from that transmitter, the panel will contact the central Emergency Response Centre and transmit a supervisory report. The account is then flagged with a "restore report within 48 hours" condition. If this is not received, a direct follow-up with the customer, and most likely, a service call is necessary.

Closing Signal

A signal sent to the central Emergency Response Centre, usually in a commercial setting, indicating that the premises have been secured at the close of business. For an extra fee, Intercept can provide opening and closing reports to those customers who want them.

Commercial Alarm

An alarm installed in a commercial or business location as opposed to a residential alarm. Please see Residential Alarm.

Compromise

To defeat or bypass an alarm system, or any part of it.

Contact

A switch, which can be either magnetic or mechanical, which is hooked up to a transmitter.

Control Panel

Please see Panel.

Decibel

A measure of how loud something is.

Defeat

To bypass an alarm system or any part of it.

Delay

A feature of some alarm systems that permits locating the Arm/Disarm control inside the protected premises. When entering or exiting through a prearranged means, the alarm system waits the preprogrammed time delay cycle before going into duty, or alarm mode, as the case may be. The use of this feature does not allow an alarm system to be used to its full extent as an immediate acknowledgment of an intrusion is a very effective deterrent. Please see Pre-Entry Protection.

Detector

Any device that senses the presence of an intruder, an intrusion attempt, fire, smoke, or any other condition, and which is hooked up to a transmitter that transmits a "trip" when such a condition is detected.

Deterrent

Anything that discourages a break-in, such as having an alarm system installed in such a way that it is easy to see. Stickers and lawn signs on the outside of the premises are also a very effective deterrent.

Dialler

Also known as a digital communicator, the dialler is a device that can connect the panel with the central Emergency Response Centre through the phone line. A dialler is an essential part of every alarm system that Intercept sells. Another type of Dialler is a voice dialler, which uses a tape recorded voice to transmit the message verbally, instead of transmitting the message digitally. Due to the length of the transmission and the possibility of errors, it is not Intercept's policy to use or recommend voice diallers.

Direct Connect

An electric current that flows in one direction only. Batteries providing direct current provide "clean" power. Most alarm equipment operates on D.C. current. Public power provides alternating current, and it is the transformer that "transforms" A.C. power into D.C. power to power alarm equipment.

Disarm

To instruct an alarm system not to react to alarms as it normally would in an armed state.

Double Hung Window

An older type of window design, in which the lower sash can be raised and the upper sash lowered. Usually, these windows have to be "split" to protect both sashes.

Drop

Usually, as in "Phone Drop." It refers to the wire running from the main phone lines into the premises. This line is what people usually worry about when they worry about their phone lines being cut prior to a break-in.

Duress Switch

Also known as a silent panic, this is a device that will trigger a silent alarm, while at the same time ensuring that there is no indication of an alarm having been triggered at the premises.

Entry Exit Delay

Please see Delay.

Environmental Considerations

Factors that must be considered in determining the correct location for situating alarm detectors so as to provide proper protection while at the same time minimizing the risk of false alarms. Of particular concern with motion sensors, factors to be considered include humidity, temperature, swaying objects, plants, animals, etc.

Environmental Sensors

Sensors that operate even if the alarm system is in a disarmed state (for example, temperature alerts, smoke detectors, A.C. power loss, and phone line loss).

Exit Delay

Please see Delay.

Failure To Alarm

A fault or problem existing in an alarm system that prevents the detection of a dangerous condition, such as an intrusion. An example would be a system that fails to work when it should.

False Alarm

An alarm signal that does not represent a dangerous or unwanted condition, but which is never-the-less interpreted as such by the Emergency Response Centre. A false alarm can lead to a police dispatch. Commonly caused by some fault in the system, user error, phone line problems, etc. It is worth remembering that approximately eighty-five (85) percent of all false alarms are generated by user error.

Fresh Air Contacts

Fresh Air Contacts are detectors designed to allow windows and/or patio doors to be left partially open for air circulation, but at the same time remain alarmed, so that they will warn if tampering occurs. The most common approach on sliding windows or patio doors is to place a second magnet approximately six (6) inches from the original magnet, so that the customer has a choice of either closing the opening fully, or lining up the second magnet on the frame with the reed switch, thereby leaving the window open enough for air circulation, but not open enough to permit unauthorized access. Under no circumstances should a fresh air contact be left wide enough for someone to slip in, thereby defeating the purpose of the alarm system. It is Intercept policy to recommend that a fresh air opening be no more than six (6) inches wide. Another way to install fresh air contacts is on Casement windows, which are defined a windows that crank rather that slide open, in order to achieve a fresh air opening. On this type of window, the contact point must be moved towards the hinge until a satisfactory opening for fresh air circulation is achieved, while care is taken it is a small enough opening so that it will still allow for an alarm if the window is opened any further. The problem with this procedure comes with environmental forces such as wind, which may blow the window further open, thus setting off the alarm. Service personnel must ensure the customer is instructed about this possibility and advised to keep their window as closed as far as possible.

GAP

The distance allowed between the reed switch and the magnet before the reed switch changes position. This change of position is what tells the transmitter to signal the main control unit. Physical factors affecting the GAP are the composition of the material upon which the switch is mounted (steel doors, for example, must have a spacer inserted under the magnet to prevent magnetic failure over time). Different GAPS are designed into system, primarily by changing the size of the magnet. Intercept's inside contacts have a designed gap of one-half (1/2) to three-quarters (3/4) of an inch, with the preferred separation being one-quarter (1/4) of an inch.

Glass Break Detector

A device mounted on or near a window which detects the breakage of glass, both by the frequencies (sound) and vibration (shock) which are generated when glass breaks. Different types of glass create different frequencies when they break, and the installed detector must be capable of working with the type of glass situated at the premises. These sensors are prone to false alarms, due to environmental reasons, such as a glass dropping on the floor, a dishwasher clicking dishes together, and/or even children screaming. The location chosen for a glass break sensor is extremely important, as an alarm siren or even arm/disarm chirps can also trip the sensor. If a glass break detector is located too close to a siren, it will create an endless loop after the first trip. The first trip will set off the siren. The siren will trip the glass break. The glass break will hear the siren and then trip the alarm again. As is apparent, this can go on indefinitely.

Hard Wire

A system in which the detectors are connected with wire, as opposed to wireless system that uses radio transmitters. Hard wire systems are not recommended for most installations, due to the difficulty of installing them and the difficulty of the end user working with them.

Rate of Rise Heat Sensor

A sensor that is triggered by a rapid rise or fall in temperature, indicating either a fire or an environmental problem at the protected premises.

Hang Up

An expression, meaning that the device (usually a panel) refuses to respond to any commands. It is usually fixed by completely powering the unit down, for a minimum of one (1) minute so as to free up the RAM memory, and then powering it back up.

High Risk Account

An account that stands to suffer a high dollar loss in the case of successful burglary, or an account that has a high likelihood of a break-in taking place, (for example, a pharmacy with narcotics in stock).

Holdup Alarm

Please see Duress Switch .

Indicator

A light or LED display which indicates the status of an alarm system.

Infrared Detector

A detector that operates by detecting an intruder by his body heat. The proper installation and use of these sensors is subject to environmental concerns.

Interlacing

A method of coordinating wireless sensor check-ins and communication, so that there is no loss of signals with two or more transmitters trying to communicate at the same time cancelling each other out.

Intrusion Alarm

An arrangement of sensors designed to detect the presence of an intruder and/or an attempt to break into a protected location.

Level of Protection

Exactly what constitutes proper protection is something upon which everyone has a different opinion. It is Intercept's policy to present different options to the customer, from which the customer can pick the level of protection that they want.

Line Cut Monitor

A device attached to a telephone line, either at the central Emergency Response Centre in the case of a direct wire account, or, more normally, at the premises itself, that will detect if the phone line is cut or shorted, and which will then signal an alarm.

Line Seizure

Line seizure, otherwise known as an eight (8) pin plug, is necessary for the proper operation of Intercept's alarm system. It is company policy that every alarm system installed, must have a line seizure plug installed. Line seizure works by taking control of the telephone line. That is, if any one else is on the phone, or if phone is off the hook, or if someone is trying to phone in, the line seizure works by "dropping" anything else connected to the phone line, and taking control of the phone line to phone the monitoring centre.

Line Supervision

Any system used in direct wire accounts, in which a known current (either AC, DC, or constant communication) is at all times present on the line. In the event the line is then cut or shorted, the signal will then be changed. Upon detection of this change, an alarm condition will be indicated and the appropriate response taken.

Local Alarm

An alarm that makes a noise on the premises when activated. It is not usually recommended due to its low deterrent value, and because, as there is no monitoring of such an alarm, there is also no supervisory capacity, (i.e., if something goes wrong, no one will know).

Lost Check-In

In a supervised wireless alarm system, each transmitter or zone must check in with the panel on a regular basis. The panel supervises these check-ins by listening for them on a regular basis. If a transmitter fails to check in with the panel, the panel will generate a lost check-in report and transmit it to the monitoring centre. The monitoring centre logs these reports and transmits them to the service department every day.

Louver Window

A type of window, consisting of many slats of glass, three (3) or four (4) inches wide, that all open together, therefore making it very difficult to protect.

Low Battery

In a supervised wireless alarm system, each transmitter reports to the panel on a regular basis. These reports tell the panel if the transmitter is active, and what its status is. Intercept transmitters have an internal circuit that monitors the battery voltage, and informs the panel when the voltage drops below a point preset by the manufacturer. Upon receipt of this information, the panel transmits a low battery report to the Emergency Response Centre, who, in turn, transmits the information to the service department. How long a transmitter will continue to function after having reported a low battery condition, depends upon the type of battery installed. (For example, a lithium battery will maintain a high voltage right to the end of its very long service life, and then drop off quickly, while a standard Alkaline-Manganese Dioxide battery will not last as long, but will drop off slower.) Intercept estimates that it would take weeks or possibly even months in the case of an Alkaline-Manganese Dioxide battery, and weeks in the case of a lithium battery.

Magnetic Contact

A magnetically operated switch, which is typically used on doors and windows to detect opening. Usually the switch and the attached transmitter are mounted on the frame, and the magnet is mounted on the moving surface. It is a big advantage over the older style mechanical switches.

Magnetic Surface

When mounting magnetic contacts on iron or steel (i.e., a fire door or metal door frame, which are themselves magnetic in nature), it is necessary to use a non-conducting spacer (i.e., plastic, wood, or aluminum) to hold both units one-quarter (1/4) of an inch away from the iron or steel surface. Failure to do this will result in the eventual loss of magnetic flux to the surrounding iron or steel, which can trigger false alarms.

Medical Alert

An alarm signal that indicates a medical problem. Usually transmitted by an invalid, elderly or sick person with a mobile transmitter button that they can push signalling a medical alarm. Please see Medical Control Form.

Medical Control Form

Form filled out with information pertaining to a Medical Alert.

Mirrors

Mirrors are an excellent blocker of RF transmissions. Therefore, caution should be used in locating wireless sensors in an area that is surrounded by mirrors.

Money Trap

A special switch placed in the bottom of a cash drawer, which is activated by the act of pulling money out of it.

Monitored Alarm

A local alarm, which is also monitored at Intercept's central Emergency Response Centre. This is the only type of alarm that Intercept sells. When an alarm is monitored, is provides the user with the support and service that are necessary for the proper utilization of an alarm system.

Motion Detector

Usually a PIR. Please see PIR.

Normally Closed

A switch whose contacts are normally closed. For example, in a magnetic switch when the magnet and the reed switch are in close proximity, the contact is closed. Another example would be a contact (such as a door) which is considered to be at rest or in its standard position when it is closed.

Opening Signal

A signal transmitted by the alarm system to the central Emergency Response Centre, signifying that the premises have been properly opened. There are many different ways this can be programmed. An example might be that the central station must receive an opening signal by a certain time, or they will telephone the store owner or manger at home. This is a positive management tool for which Intercept charges extra, and which is very useful in commercial applications.

Overhead Door

A truck, loading dock or garage door that needs special wide-gap magnetic contact, known as overhead door contacts.

Overhead Door Contacts

A special set of heavy duty contacts that are designed to work in rough conditions and deal with the gaps involved in big, loose-fitting doors.

Panel

The main control in an alarm system, and the brains of the system, which is usually the communication centre.

Panic Alarm

The panic feature in an alarm system, which allows the user to trigger a full alarm manually, even when it is disarmed. A panic alarm feature is not to be confused with a Holdup alarm, which is silent.

Parallel Circuit

Normally open devices, connected in a parallel circuits. The components are connected across each other, so that the circuit segment could be drawn showing components leads bridging common conductors like rungs across a ladder. All components share a common positive and a common negative connection. This device is activated by the reed switch closing, thereby making a connection between the negative and positive conductors which causes an alarm. It is comparable to a series Circuit.

Party Wall

A demising wall shared by two premises. Typically, it exists in a shopping centre or an apartment building, and would allow easy, undetected access to a burglar coming directly through the wall from the adjacent space. In such a situation, internal detectors such as motion detectors, are very important.

Passive Detector

A sensor that does not emit any kind of energy in order to perform its detection function is most commonly referred to as a PIR (Passive Infrared).

Pattern

The shape and volume of coverage of motion detectors. Factors concerning the determination of the pattern, include the physical limitations of the premises and/or its contents, and any environmental concerns.

Perimeter Protection

A series of sensors designed to detect intrusion at all logical points of entry to the premises. Please see armed home, and arm away.

Polarity

Reeds are bimagnetic, which means they are sensitive to the polarity of the magnet. Therefore, it is necessary to ensure that the reed switch and the magnets are orientated the same way. The easiest way to do this, is to ensure the manufacturer's label or arrow are facing in the same direction.

Police Response

Arrival of the local police at a location from which an alarm signal has been received. It can also refer to the length of time it takes the police to respond to an alarm.

Power Conditioner

A combination, voltage regulating transformer and super isolation transformer, which provide smooth, regulated, noise-free, AC voltage. Unfortunately, they are very expensive, so Intercept is presently searching for one that to supply to our accounts at a much better price.

Power Supply

Please see transformer.

Preventive Maintenance

Maintenance done to the alarm system to keep the system in top shape; aspects of which can include on-site testing, battery changes, etc.

Preventive Maintenance Contract

Please see Service Contract.

Procedures

The written operations guide that governs the proper usage of an alarm system by the end user, the standards used to install the alarm system, and the type of response that the central Emergency Response Centre will generate upon receiving a signal.

Program

The standardized set of instructions that Intercept programs into an alarm system, so as to instruct the system how to act and react, (for example what telephone number to call in the event of an alarm).

Programmer

The instrument used to install the operating program in the alarm system.

Protected Area

That portion of a premises, covered by an alarm system. Due to the cost and use considerations, the entire premises is not usually covered. For example, in a residential alarm situation the second story windows are rarely protected unless there are other environmental concerns that make protecting these windows necessary. It is not Intercept's job to decide what should, or should not, be protected. It is our job is to present all the available options to the customer to the best of our ability, and then to allow the customer to decide what level of protection is best for them.

Radio Frequency

Otherwise expressed as RF, it refers to frequencies above one hundred (100) KHZ.

RFI

Radio frequency interference, either man-made or natural, intentional or unintentional, is an electromagnetic propagation which results in unintentional and undesirable response from the alarm equipment.

Reed Switch

A type of magnetically operated switch, which is made by sealing two (2) small steel leaves, or "reeds", inside a glass tube. When a magnet is brought near, the reeds flex slightly, touching each other to complete the circuit. When the magnet is removed, the reeds spring apart, breaking the circuit. Please see Magnetic Contact.

Receiver

A unit that accepts or receives a communication from any of Intercept's alarms, and which is located at the central Emergency Response Centre.

Residential Alarm

An alarm system installed in a private home as opposed to one installed in a business. These are two very different markets that have different applications for alarm systems. Please see Commercial Alarm.

Response

As in police, medical, or fire response to an alarm.

SAW

Abbreviation for Surface Acoustical Wave resonator, which is a special chip in each transmitter that keeps the frequency precise, without drift. It makes the transmitter impervious to temperature extremes, vibration and humidity.

Sensor

A device that detects an occurrence of any kind to cause it to trip a transmitter, that sends a signal to the panel, which then analyzes the signal and responds as programmed.

Series Circuit

All normally closed switches are connected in a series circuit, (i.e., a circuit whose components are, in effect, connected in a string, or end to end, so as to create a single current path in a normally closed circuit). An alarm is caused by a normally closed switch, opening and breaking the current path in the circuit, thereby triggering an alarm.

Service Contract

A signed contract between Intercept and the end user that agrees to the payment of a certain fee for the maintaining of the alarm system and its parts.

Shelf Life

The length of time in which equipment will remain in good condition while sitting in stock, or "on the shelf". It is a major item of concern regarding batteries, which should be rotated as often as possible.

Silent Alarm

An alarm that is set to transmit an alarm signal to the central Emergency Response Centre without alerting anyone at the premises that it has been activated.

Siren

A noise-maker activated by the alarm system.

Slider Window

A type of window found in older homes in which both sides are moveable, so entry can be made from either end. It is important the both planes of a slider window be protected as other techniques, such as pinning one side can later be defeated by the customer without any indication that this has been done being given to the alarm system, thereby leaving an unprotected entry point. Please see Split.

SMT

Abbreviation for Surface Mount technology.

Smash and Grab

A burglary in which a display window or some other readily available object is smashed, valuable items are grabbed or vandalized, and the burglar flees within seconds. Only physical protection can stop such attacks.

Smoke Detector

A device that responds to the by-products of combustion.

Spike

A momentary increase in electrical voltage or current. Spikes can damage or "hang up" electronic equipment, such as a panel. This problem can be dealt with through the use of line chokes, and in severe conditions, through the use of power conditioners.

Split

An installation technique that is used to hook up more than one contact to a transmitter. For example, on slider windows, it is necessary to hook up a contact to each inside plane of glass as well as the frame, so that if either plane is moved, a signal will be sent.

Spot Protection

Protecting a specific, small area of particular value to the customer. Usually done with its own contact and its own zone programmed as an environmental zone, so that it will be constantly monitored to respond to even if the system is disarmed.

Standby Battery

A battery used to provide power to an alarm system in the event of a AC power line failure. Intercept uses a rechargeable battery for this purpose.

Strobe Light

A light that flashes with very short, very bright flashes. It is used to supplement a siren.

Structured

Wiring The wired home is essential in today’s society - it provides access to a high speed internet, digital television, and data networking for advanced technology. Your home will be wired for today’s technology and ready for the future.

Supervised

In wireless technology, it is a system of keeping track of all transmitters that are programmed into a panel and their status. All alarm systems sold by Intercept are supervised.

Swinger

Used to describe an intermittent problem that the service department has trouble tracking down, and consequently, even greater trouble, fixing. It is not common as Intercept's policy is to always replace suspect equipment, so therefore monitoring centre can usually identify the transmitter from which the problem signal came.

Tamper Switch

A switch mounted to detect the opening of particular compartment. For example, a tamper switch might be mounted and programmed in such a way so as to create an alarm if the house phone box was opened. At this time, due to environmental concerns, it is not Intercept's policy to recommend this procedure.

Telephone Answering Service

While some alarm companies use them to monitor their account, Intercept does not approve of the practice.

Time Delay

A time interval that can be programmed into the panel, so as to provide a feature such as entry delay, exit delay, etc.

Transient

Please see Spike.

Transformer

Also known as a power cube, it is device that transforms main line AC power into power that can be used by the alarm panel.

Transmitter

A device that transmits a signal by RF to the main panel. There are many different types of sensors that can be hooked up to a transmitter.

U.L.

Abbreviation for Underwriters Laboratories, a private organization that issues standards of safety for components, equipment, and their operation.

U.L.C.

Abbreviation for Underwriters Laboratories, Canada, which is the Canadian branch of a private organization that issues standards of safety for components, equipment, and their operation.

U.L.C. Listed

Equipment for that has been tested by ULC and that the manufacturer has paid a fee for to be listed.

U.P.S.

Abbreviation for Uninterruptable Power Supply. It is a device that provides a steady source of electric energy to a piece of equipment. For example, the backup battery in Intercept systems is considered a U.P.S.

Walk Test

A procedure which consists of actually walking through the area protected by a motion detector so as to determine the actual limits of its coverage.

Wide Gap Magnetic Contact

A unit which uses an extra sensitive switch and/or an extra strong magnet to obtain a wider than normal operating range. At Intercept, it is assumed that any gaps over three-eights (3/8) of an inch are wide gaps.

Wireless

A method of sending signals from the detection device to the panel without the expensive and time-consuming method of running of wires.

Zone

It is Intercept's practice to divide an alarmed premises into zones in order to pinpoint the specific areas of intrusion, or the specific environmental sensors.

Zone Description

A method of identifying zones clearly so that every one involved with the alarm system (i.e., the customer, the service department, and the police) can all easily identify the exact location of the zone.
