Duct Smoke Detector Installation Location

Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector.

Duct smoke detector installation location.

Duct preparation the duct detectors are designed for use in ducts where the air velocities are from 300 to 4000 feet per minute. 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. 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. One unit can accommodate multiple installation footprints to overcome mounting constraints.

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. Installation instructions for duct smoke detectors mounted on combination fire smoke or smoke dampers ii detector 04 12. 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. Tool free plug in sampling tubes speed and simplify installation.

Consult nfpa 90a nfpa 72 and local codes to determine where smoke detectors are required. Duct smoke detection may be useful in preventing injury and property dam age in instances such as the following. Furthermore intentions for using duct smoke detectors should not be a substitute for area smoke detectors. 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. 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. Hvac duct smoke detection.

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. Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system.
