Description Specifications
The Model SD505-DUCTR Addressable Duct Smoke Detector with Relay provides early detection of 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-DUCTR is a heavy duty metal housing with a pre-installed SD505-APS Analog Photo Electric Smoke Sensor and relay module. When smoke is detected in a duct, the unit communicates the condition to the IntelliKnight FACP. The built-in relay module, in turn, turns off fans, blowers, and other devices.
