GENERAL DESCRIPTION
System Sensor Model BEAM1224/BEAM1224S is a long range projected beam smoke detector designed to provide open area protection. It is to be used with UL-listed, separately supplied power (4-wire) control panels only. The detector consists of a transmitter/receiver unit and a reflector. Smoke entering the area between the transmitter/receiver and reflector causes a reduction in signal. When the obscuration reaches alarm thresholds (chosen at the transmitter/receiver unit), the detector generates an alarm signal. Complete blockage of the beam causes a trouble signal. Slow changes in obscuration due to a build up of dirt or dust on the lens of the detector are compensated for byD400-73-00 2 I56-2294-004R a microcontroller that continuously monitors the signal strength and periodically updates the alarm and trouble thresholds. When the self-compensation circuit reaches its limit, the detector generates a trouble signal, indicating the need for service.
