Alarm Control Panel: it reads sensor inputs, tracks arm/disarm status, and signals intrusions. It is
typically a circuit board inside a metal enclosure, along with a power supply.
Sensors: Devices which detect intrusions. Sensors can detect intruders by a variety of methods,
such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for
motions, sound, vibration, or other disturbances.
Alerting devices: These indicate an alarm condition. Most commonly, these are sirens,
and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of
intrusion, and potentially scaring off burglars. These devices may also be used to warn
occupants of a fire or smoke condition.
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 multi-character display, or both.
Interconnections between components: This may consist of direct wiring to the control
unit, or wireless links with local power supplies.
