FIREX® the recognized leader in residential fire protection, brings you the latest in duct smoke detection technology. FIREX® Duct Smoke Detectors provide early detection of smoke and products of combustion present in air moving through an HVAC duct. These devices are designed for prevention of smoke recirculation in areas by the air handling systems. Fans, blowers, and complete systems may be shut down in the event of smoke detection. Our universal voltage models will operate on any one of four input voltages..

Air sampling is accomplished by two tubes, which protrude into the duct. An exhaust tube of one standard length (7'') is provided with each FIREX® Duct Smoke Detector. Intake sampling tubes, which must be ordered separately, are available in three standard lengths.

Duct smoke detector mounting is accomplished by the use of a mounting template and four sheet metal screws, which are provided.
