The Apollo Duct Smoke Detector provides early detection of smoke in the air moving through heating and ventilation (HVAC) ducts in comŽmercial and industrial premises. Its purpose is to prevent the recirculation of smoke from an area on fire to areas unaffected by the fire. Duct smoke detector part no 53546-021 is designed to accept a conventional detector head. See Table 1 overleaf for details of suitable heads. Duct smoke detector part no 53546-022 is designed to accept an analogue addressable detector head.
Under no circumstances should a duct smoke detection system be used as the sole method of detecting fire. They should be used as supplemen-tary detection in a fire detection system.
