Photoelectric detector

System Sensor's 2251BR Remote Test Capable photoelectric detector.

04/30/2012


System Sensor’s 2251BR Remote Test Capable photoelectric detector adds simplified remote testing capability to the updated DNR and watertight NEMA DNRW InnovairFlex intelligent duct smoke detector housing. This new detector is especially designed for use in applications requiring a remote test. The “remote test capable” text printed on the detector cover can identify the new 2251BR detector. The detector enables updated DNR (W) duct smoke detectors to be tested remotely when used in conjunction with RTS151 or RTS151KEY remote test stations. This eliminates the need for the DCOIL or external 24 V power to duct smoke installations, thereby reducing the additional first cost and installation labor associated with the DCOIL and pulling external power. The InnovairFlex duct smoke detector can accommodate multiple installation footprints to overcome mounting constraints. It offers superb false alarm immunity, a broad temperature range of –4 to 158 F, easily visible status indicators, and a readily accessible test feature.
