How does a security system work?

A security system consists of a control panel which functions as a central computer, receiving messages from a number of sensors that act as the "eyes" and "ears" of the system. If the system is "armed" and a signal is received by the panel it automatically dials a Central Monitoring Station via a built-in telephone communicator. The station operator then alerts the appropriate authorities.

Secure at Home.

Keypads, located near common entry doors allow you to control the system. They communicate with a control panel that contains an automatic dialer to call the monitoring station. Any number of other products make up a system. Generally included are:

• Magnetic Contacts to protect doors and windows that open
• Glassbreak sensors to protect windows and glass doors
• Motion sensors to detect movement within a defined area
• Panic switches that can be manually operated
• Sirens and sounders to sound a local alarm
• Smoke detectors to detect smoke and fire
• Heat detectors are often placed in attics and kitchens
• Barrier Bars protect basement windows

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 motion sensors off. System smoke detectors are always active. Your security professional can help design the system that works best for you, there are many options available.

What is a magnetic contact?

A two-part device that protects doors and windows that open. One part of the contact is a switch, installed in the door or window jam, the other is installed in the door or window itself and contains a magnet that signals an alarm when it moves "out of contact" with the switch. To ensure an optimum level of detection, every door and window that opens would require a magnetic contact. If a burglar attempts to cut the wire leading to the contact, the alarm will activate.

How does a glassbreak sensor work?

There are two basic types of glassbreak sensors -- "acoustic" sensor that is mounted in the wall or ceiling and listens for the sound of breaking glass in a window or door and a "shock" sensor that is mounted on the window and "feels" the shock of breaking glass. Optimally, a glassbreak sensor can detect an intruder while he is still outside your home. Your security dealer will be able to recommend the best product for each room in your home.

What is a PIR?

A passive infrared motion detector (PIR) is a security sensor that detects an intruder by sensing his body heat as he passes through the area "covered" by the PIR. Since PIRs are motion sensors, they are designed to be used when no one is at home or when the family will not be moving through the protected areas. If you have dogs or cats home when the PIR is on, let your security dealer know so he can provide you with the appropriate product.

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.
