BEAM355 and BEAM355S Reflected-Type Beam Smoke Detectors FireLite BEAM355 and BEAM355S are reflected beam smoke detectors for protecting areas with high and sloping ceilings, and wide-open where spot-type smoke detectors are difficult to install maintain. applications are atriums, cathedral aircraft hangars, warehouses, sporting arenas, halls, and enclosed parking facilities. They are with the MS-9600 Series and MS9200 Series in or CLIP mode. Installation of the single-ended design is much quicker than a dual-ended projected detector. Alignment is easily accomplished with an sight and a two-digit signal strength meter incorporated the beam detector. Listed for operation from to the BEAM355 and BEAM355S are usable in open area where temperature extremes exceed the design of other types of smoke detection.
