The Silent Knight SK-DUCT is an addressable photoelectric air duct smoke detector. It detects smoke and products of combustion in air moving through HVAC ducts. This version includes the photoelectric sensor head and no relay module. On alarm, the panel can shut down fans and blowers per its programming.
The housing is a rugged steel back box with a clear cover. In addition, the pivoting design fits square or rectangular footprints. It mounts to round or rectangular ducts. The patented sampling tube installs from the front or back without tools. There is also space inside to add an SK-RELAY addressable relay module.
