FireLite BEAM355 Addressable Projected Beam Smoke Detector
The Fire·Lite BEAM355 and BEAM355S are intelligent, addressable projected beam smoke detectors for protecting open areas with high and sloping ceilings, and wideopen areas, where spot-type smoke detectors are difficult to install and maintain. Ideal applications are atriums, cathedral ceilings, aircraft hangers, warehouses, sporting arenas, concert halls, and enclosed parking facilities. They are compatible with the MS-9600 and MS9200UD addressable Fire Alarm Control Panels (FACPs). Installation of the single-ended reflective design is much quicker than a dual-ended projected beam detector. Alignment is easily accomplished with an optical sight and a two-digit signal strength meter incorporated into the beam detector. Listed for operation from –22ºF to 131ºF, the BEAM355 and BEAM355S are usable in open area applications where temperature extremes exceed the design limits of other types of smoke detection.
The BEAM355 and BEAM355S are a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector, it causes a reduction in the signal strength. When the smoke level (signal strength) reaches the predetermined threshold, an alarm is activated. The detectors have four standard sensitivity selections as well as two Adapt™ settings. When either Adapt™ setting is selected, the detector's advanced software algorithms automatically adjust to the optimum sensitivity for the specific environment. The protection range is 16 to 328 feet and there are built-in isolators for Style 7 operation.
The BEAM355S has an integral sensitivity test feature of a filter attached to a servomotor inside the detector optics. Activation of the RTS451 remote test station moves the filter into the pathway of the light beam, testing the detector's sensitivity. This sensitivity test feature allows the user to quickly and easily meet the annual maintenance and test requirements of NFPA 72, without physical access to the detector.
