DUCT ALARMS

DUCT SMOKE ALARMS

Duct Smoke Alarms 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 duct smoke detector units are designed to operate in duct widths from 12 inches to 10 feet wide with an air velocity between 500 and 4000 feet per minute.

To verify correct installation, the pressure differential between the input and exhaust tubes should be measured using a Magnehelic pressure gauge or equivalent. An acceptable reading must be between 0.01 and 1.2 inches of water. For a Smoke Duct Detector unit to operate correctly, it must be installed 6 duct widths from any obstruction i.e. elbows, deflector plates, filters, dampers, etc. In situations where the criteria cannot be met, deviations are acceptable providing they meet the pressure differential requirements.

As a guideline, the detector head should be cleaned every six months or as required. The best methods of cleaning are to vacuum the detector head thoroughly or to blow the detector head out using compressed air. Do not use chemicals to clean the detector head housing as this could contaminate the detector head and damage the casing. Sensing tubes must be inspected and cleaned in accordance with the schedule as determined above, to allow the free flow of air through the sensing tube.
