System Sensor BEAM1224 single-ended reflected-type projected beam smoke detector.

This commercial fire-alarm detector is designed for large open areas and high ceilings where conventional spot smoke detectors may be difficult to install or service. The BEAM1224 uses a single-ended reflective design with the transmitter/receiver at one end and a reflector at the opposite end. System Sensor specifies this model as a 4-wire conventional beam detector for use with compatible UL-listed fire alarm control panels.
