FSB-200 and FSB-200S

The Notifier FSB-200 and FSB-200S 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 NFS-3030, NFS2-3030, NFS-640, NFS2-640, and NFS-320 in FlashScan® or CLIP mode, as well as legacy addressable panels. 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 FSB-200 and FSB-200S are usable in open area applications where temperature extremes exceed the design limits of other types of smoke detection.
The FSB-200 and FSB-200S 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 Acclimate® settings. When either Acclimate® setting is selected, the detector’s advanced software algorithmsautomatically adjust to the optimum sensitivity for the specific environment.
