Duct Smoke Detectors Overview 

FireX®, the recognized leader in 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.

 

The detector also offers universal voltage input compatibility 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.  Please see the specific model for details.

 

Accessories for the duct smoke detectors are also available to provide the most complete functionality ever in these devices. Audible and visual indicators as well as remote test/reset functions are just a few of the accessories.  Review our entire line of accessories in this section.
