Hvac Duct Smoke Detector

If the duct system is designed to carry more than 2000 cfm 5 tons nominal of air you need one in the return if imc is being followed and the supply if nfpa is being followed.

Hvac duct smoke detector. The duct smoke detector should be compatible with building automation and fire alarm systems. Tool free plug in sampling tubes speed and simplify installation. Nor should it serve as an early warning detection system. Furthermore intentions for using duct smoke detectors should not be a substitute for area smoke detectors.

Plug in tool free sampling tubes speed installation. Both also have exceptions that allow the deletion of the return duct smoke detectors if the area served is supplied with area smoke detectors and they are configured to control the hvac system in the same way that the duct detectors would have. One unit can accommodate multiple installation footprints to overcome mounting constraints. The duct smoke detector samples air for early detection of smoke and products of combustion present in air moving through hvac ducts.

Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. Hvac duct smoke detection. Nfpa 72 also states that a duct smoke detector is not allowed to replace an area smoke detector. Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system.

An adjustable housing overcomes mounting constraints. A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust.
