The FireLite BEAM355 and BEAM355S are intelligent, addressable reflected beam
smoke detectors for protecting open areas with high and sloping ceilings, and
wide-open areas, where spot-type smoke detectors are difficult to install and
maintain. Ideal applications are atriums, cathedral ceilings, aircraft hangars,
warehouses, sporting arenas, concert halls, and enclosed parking facilities.
They are compatible with the MS-9600 Series and MS9200 Series in LiteSpeed or
CLIP mode. 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 -22°F to 131°F, the BEAM355 and
BEAM355S are usable in open area applications where temperature extremes exceed
the design limits of other types of smoke detection.
