Duct Smoke Detector Installation Location

If the unit operates off a battery test the detector weekly and replace the battery at least once a year.

Duct smoke detector installation location.

Duct smoke detection can also serve to protect the air conditioning system itself from fire and smoke damage. The duct smoke detector is equipped with an auxiliary relay. Designers should also remain aware that duct detectors may not substitute for area smoke detection. Like smoke detectors co alarms need to be tested regularly and cleaned as indicated in the manufacturer s use and care booklet.

E pdd duct smoke detector installation sheet operation the duct smoke detector s primary purpose is to provide early warning of an impending fire and shut down the hvac unit in order to prevent smoke from circulating throughout the building. Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector. Consult nfpa 90a nfpa 72 and local codes to determine where smoke detectors are required. One unit can accommodate multiple installation footprints to overcome mounting constraints.

Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. In the areas where smoke detectors become inaccessible designers should include smoke detection controls remote from the inaccessible area. A heating ventilating or air conditioning hvac fan motor overheats and resulting smoke is sensed by the duct smoke detector installed in the main supply duct.
