System Sensor

Remote Test Capable photoelectric detector (2251BR)

With the launch of a new intelligent Remote Test Capable photoelectric detector (2251BR), System Sensor adds simplified remote testing capability to the updated DNR and watertight NEMA DNRW InnovairFlex intelligent duct smoke detector housing. The detector is especially designed for use in applications requiring a remote test. The Remote Test Capable 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.
