Model SD505-DUCTR Analog Duct Smoke Detector with Relay Module
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.
