Duct Smoke Detection System and Method

摘要

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 duct end is extendable to the duct and is not 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 by a smoke generator that generates smoke under pressure.
