SINGLE-ENDED REFLECTED TYPE BEAM SMOKE DETECTOR
BEAM1224A System Sensor Single-ended Reflected Type Beam Smoke Detector
Model BEAM1224A System Sensor is a four-wire conventional reflected beam smoke detector, which is uniquely suited for protecting open areas with high ceilings, where other methods of smoke detection are difficult to install and maintain. It is to be used with ULC Listed control panels only. An advantage of this single-ended reflective design is that it is much easier to install than the dual-ended projected beam detectors.
Alignment is quickly accomplished via an optical sight and a two-digit signal strength meter incorporated into the product. Another advantage of the BEAM1224A is that it is listed for operation in temperatures ranging fromÃƒÆ’Â¢ÃƒÂ¢''Å¡Â¬Ãƒâ€¦''Å“30Â°C to 55Â°C. This means it can be used in open areas to provide early warning in environments where temperature extremes may exceed the capability of other types of smoke detectors.
BEAM1224A System Sensor consists of a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector, the smoke causes a reduction in the signal. When the smoke level reaches the predetermined threshold, an alarm is activated. BEAM1224A has four stand(more...)
