Duct Smoke Detector Installation Location

The duct smoke detector is equipped with an auxiliary relay.

Duct smoke detector installation location.

Like smoke detectors co alarms need to be tested regularly and cleaned as indicated in the manufacturer s use and care booklet. Consult nfpa 90a nfpa 72 and local codes to determine where smoke detectors are required. Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system. 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.

Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector. Duct smoke detection can also serve to protect the air conditioning system itself from fire and smoke damage. 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. Designers should also remain aware that duct detectors may not substitute for area smoke detection.

Tool free plug in sampling tubes speed and simplify installation. If the unit operates off a battery test the detector weekly and replace the battery at least once a year. Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. One unit can accommodate multiple installation footprints to overcome mounting constraints.

Installation instructions for duct smoke detectors mounted on combination fire smoke or smoke dampers ii detector 04 12. 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. Furthermore intentions for using duct smoke detectors should not be a substitute for area smoke detectors. Nor should it serve as an early warning detection system.

Duct smoke detection may be useful in preventing injury and property dam age in instances such as the following. The duct smoke detector is designed for use in duct. Duct preparation the duct detectors are designed for use in ducts where the air velocities are from 300 to 4000 feet per minute.
