A burglar alarm consists of a panel, door and window contacts, motion detectors and siren plants. Each component is wired to the central panel. There are several areas where a burglar alarm. A zone can be a whole room or a specific component burglar alarm. The panel receives signals from each zone and sends these signals to the monitoring center. The panel is connected to the telephone line. This allows the burglar alarm to communicate with the control center.
Setting the Alarm
A burglar alarm is set by entering a code number on the keypad. You then have a set amount of time (usually several seconds) to exit the building after the alarm has been set. Upon entering the building, the new code is entered to disable the burglar alarm. If the code is incorrect, the burglar alarm panel sends a signal to the monitoring station. The monitoring center will then notify the authorities.
The triggering of an alarm
A person can shoot a burglar alarm by opening a door or window or by activating a motion detector. Within seconds, the component sends a signal to the central panel, causing the burglar alarm goes off. Usually a siren sounds when an alarm is triggered; however, a silent alarm can be installed. People with hearing problems can choose a flashing light that an intruder alerts. If the alarm system is monitored, the panel makes a phone call to a monitoring center when the alarm is triggered.
When the monitoring center receives a call from an alarm system, you can see the area that caused the alarm. The monitoring center then notifies the authorities and alarm system owner. The police then sent to the location of the alarm system to investigate.
Other monitoring options
If the alarm is triggered, the monitoring center can call any phone number you specify. You may have to call your cell phone instead of the authorities. You can also opt to have both a phone number of your choice and notified authorities when the burglar alarm will go off. Some call centers monitoring the location of the burglar alarm to verify that there is a false alarm before alerting authorities.
