Smoke detector BEAM355/355S

Fire-Lite’s BEAM355 and BEAM355S are intelligent, addressable projected 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. 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. Usable in open area applications where temperature extremes exceed the design limits of other types of smoke detection. Four standard sensitivity selections as well as two Acclimate® settings (automatically adjust to the optimum sensitivity for the specific environment). Integral sensitivity test feature allows you to quickly and easily meet the annual maintenance and test requirements of NFPA 72, without physical access to the detector. Transmitter/receiver built into same unit. 16’ to 328’ (use BEAMLRK beyond 230’) protection range. Digital display no special tools required. Built-in automatic gain control compensates for signal deterioration from dust build-up.
