Intruder Alarm System (Safety and Security Systems)

The system designed to detect intrusion – unauthorized entry – into a building or area. Systems are also called security alarms, security systems, alarm systems, intrusion detection systems, perimeter detection systems,and similar terms..

Powerins(system Integrator) offers combination systems provide both fire ,property and personal protection via wired and Wireless networks.

Design



The most basic alarm consists of one or more sensors to detect intruders, and an alerting device to indicate the intrusion. However, a typical premises security alarm employs the following components:

  • Premises control unit (PCU), or panel: The "brain" of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions

  • Sensors: Devices which detect intrusions. Sensors may place at the perimeter of the protected area, within it, or both. Sensors can detect intruders by a variety of methods, such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for motions by PIR.ultra sonic, microwave sensors, to detect sound by sound sensors , to detect vibration by vibration sensors, or other disturbances.

  • Alerting devices: These indicate an alarm condition. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of intrusion, and potentially scaring off burglars.

  • Keypads: 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 mulch-character display, or both.

  • Interconnections between components. This may consist of direct wiring to the control unit, or wireless links with local power supplies.

  • Security devices: Devices to detect thieves such as spotlights, cameras & lasers.In addition to the system itself, security alarms are often coupled with a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station. Operators at the station see the signal and take appropriate action, such as contacting property owners, notifying police, or dispatching private security forces. Such signals may be transmitted via dedicated alarm, telephone lines, or Internet.
