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.
