Reflector-Type Beam Smoke Detector

The honeywell intelligent, addressable reflected beam smoke detectors protects open areas with high and sloping ceilings, and wide-open areas, where spot-type smoke detectors are difficult to install and maintain. Ideal applications of beam smoke detectors are atriums, cathedral ceilings, aircraft hangars, warehouses, sporting arenas, concert halls, and enclosed parking facilities. Detectors are compatible with honeywell’s intelligent fire alarm control panels in FlashScan® or CLIP mode, as well as with the FS90, XLS200, and XLS1000 in CLIP mode only. 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. Detectors are listed for operation from –22°F to 131°F, the detectors are usable in open area applications where temperature extremes exceed the design limits of other types of smoke detection.

The intelligent addressable reflected beam smoke detectors 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 algorithms automatically adjust to the optimum sensitivity for the specific environment. The beam smoke detectors has an integral sensitivity test feature of a filter attached to a servomotor inside the detector optics. The servomotor must be powered by +24 VDC, not SLC power. Activation of the RTS151 or RTS151KEY remote test stations 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 detectors.
