intruder alarm
The control unit is the nerve centre of the alarm and is usually situated in a cupboard, or under the stairs for a domestic system. The control unit works jointly from the mains supply and a rechargeable battery. It processes signals from the various detectors and sensors – and operates the sounders accordingly. Whilst it normally incorporates a keypad to allow you to set and unset the alarm, on most systems a separate or remote keypad will be installed. The external sounder box (usually referred to as a‘bell box’) will provide mechanical and weather protection for the warning sounder located inside the box. The bell box will be protected against unauthorised tampering or attack. Noise pollution legislation requires that external sounders do not operate for more than 20 minutes.
Fitted on the underside or inside the bell box, a strobe light will give visual warning that the alarm has activated, which is useful for identification within a row of alarm box-bearing buildings.
