SD505-ADHR Addressable Duct Housing and Relay

Detect smoke in air handling systems and prevent re-circulation with Silent Knight's addressable duct smoke detector.

The SD505-ADHR/DTS addressable duct smoke detector detects smoke and products of combustion present in air moving through an HVAC duct to prevent re-circulation of smoke into the air handling system. 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 5820XL FACP. The built-in relay module, in turn, turns off fans, blowers, and other devices.

The SD505-ADHR/DTS is designed to be used with Silent Knight's SD505-APS Photoelectric Smoke Detector and SD505-AIS Ionization Smoke Detector.
