Features

• 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 ft. (use BEAMLRK beyond 230 ft.) protection range.
• Digital display  no special tools required.
• Built-in automatic gain control compensates for signal deterioration from dust build-up.
