The Silent Knight SK-DUCT is a smoke detector for HVAC ducts in commercial and industrial locations.

Upon detecting smoke in an HVAC Duct, the SK-DUCT will transmit an alarm signal to the IntelliKnight Control Panel. The unit is housed in a heavy duty gray steel back box that is capable of adapting to both square and rectangle footprints. This detector can sense smoke or combustion particles in areas with airflow speeds up to 4000 feet per minute.
