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.
Duct smoke detector installation location.
Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system.
One unit can accommodate multiple installation footprints to overcome mounting constraints.
If the unit operates off a battery test the detector weekly and replace the battery at least once a year.
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.
Like smoke detectors co alarms need to be tested regularly and cleaned as indicated in the manufacturer s use and care booklet.
Installation instructions for duct smoke detectors mounted on combination fire smoke or smoke dampers ii detector 04 12.
The duct smoke detector is designed for use in duct.
Fad 325 v2f r duct housing with the fad 325 v2f dh analog photoelectric smoke sensor relays installation instructions for the duct smoke detector a.
Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector.
Hvac duct smoke detection.
Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring.
Duct preparation the duct detectors are designed for use in ducts where the air velocities are from 300 to 4000 feet per minute.
In the areas where smoke detectors become inaccessible designers should include smoke detection controls remote from the inaccessible area.
We will show you how to wire a system sensor duct smoke detector to a carrier bryant or icp furnace and then configure it s communicating infinity evoluti.
Duct smoke detection may be useful in preventing injury and property dam age in instances such as the following.
The duct smoke detector is equipped with an auxiliary relay.
Nor should it serve as an early warning detection system.
Duct smoke detection can also serve to protect the air conditioning system itself from fire and smoke damage.
Consult nfpa 90a nfpa 72 and local codes to determine where smoke detectors are required.
