Abstract
An assembly for testing of smoke detectors, installed to detect the presence of smoke in ductwork or through a smoke protected opening, and includes a plenum rated hose assembly having a duct end and a smoke end. The hose assembly smoke end is extendable to within the duct and is terminated with a nozzle directable at an inlet tube of a smoke detector associated with the duct, or to the detector protecting a smoke protected opening. A duct mounting plate is adapted to be sealingly installed to cover an aperture formed within the duct and to retain the hose assembly duct end. Smoke is directed into the hose smoke end. The smoke exits the hose through the nozzle and towards the inlet tube of the duct-mounted smoke detector, or towards the detector for a smoke protected opening, for testing of the smoke detector.
