What a security alarm system does is basically to sense when someone has entered a building or any other property. If such a person does not send a message to the system indicating that the entry is lawful after sometime, the system assumes that such entry is illegal and the alarm is triggered. This post will touch on the design and some other aspects of the security alarm system.
Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance (CCTV) systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control. It may even include two-way voice which allows communication between the panel and Monitoring station.
Let us peep at the design
Every security alarm system consists of one or more sensors to detect when there is an intrusion and an alerting device to indicate the unlawful entry. However, a typical home security system consists of the following components:
- The PCU or ACP?
PCU stands for premises control unit while ACP stands for Alarm Control Panel.
The “brain” of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions. In modern systems, this is typically one or more computer circuit boards inside a metal enclosure, along with a power supply.
These are the devices that actually detect the entry and send signals to the panel. They are usually placed within the perimeter of the protected area. How do they sense the entry? They do this by a number of ways. One of those is to track the opening and closing of doors and windows, or by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances.
- Alerting Devices
They are most commonly bells, sirens or flashlights that indicate the alarm conditions of your property. Because of the disturbance they create, they serve the dual purpose of scaring off burglars and notifying the homeowners of an intrusion in their home. These devices can also serve the purpose of fire alarms for occupants.
They are small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically feature indicator lights, a small multi-character display, or both. They are input devices whose main functions are to enter codes for avoiding or resetting the alarm system.
This is found between components of the system. It may consist of wireless link to local power supplies or direct link to the control unit.
- Security Devices
These are peripherals to the system itself. They are used to monitor movements within the protected area. These devices include spotlights, lasers and cameras.
