Hochiki Duct Detector Mounting Box including SDP-3 PIPE (0.6M) (SDP-3)

The Hochiki SDP-3 is a duct probe housing that lets a standard Hochiki photoelectric smoke detector, either a conventional detector or an analogue addressable sensor, be mounted on the outside of an air duct to monitor the air inside it. Air from the duct is drawn through the sampling pipe into the housing, where the detector samples it. It fits square or round section ducting (round ducts need the optional brackets). The detector is sold separately.
