Description

The Silent Knight SD505-DTS addressable duct smoke detector detects smoke as well as products of combustion present in air moving through an HVAC duct to prevent re-circulation of smoke into the air handling system. Also, the SD505-ADHR is a heavy duty metal housing with a pre-installed detector base and relay module. When smoke is detected in a duct, the unit communicates the condition to the IntelliKnight FACP. Furthermore, the built-in relay module, in turn, turns off fans, blowers, and other devices.

The Silent Knight SD505-DTS is a remote test switch that is used with the SD505-ADHR so you can remote test the Duct Detector. It also provides LED indication of the status of the SD505-ADHR. The SD505-DTS is designed to be used with Silent Knight’s SD505-APS Photoelectric Smoke Detector as well as SD505-AIS Ionization Smoke Detector.
