ADDRESSABLE DUCT HOUSING W/ SD505-APS SMOKE SENSOR PRE-INSTALLED

The Silent Knight SD505-DUCT is an addressable duct smoke detector with the SD505-APS sensor pre-installed in a heavy duty housing. The SD505-DUCT is used for detecting smoke and products of combustion present in air moving through an HVAC air handling system.

When smoke is detected in a duct, the unit sends a signal to the IntelliKnight control panel, which, depending on programming and wiring, will proceed to turn off fans, blowers, and other devices.
