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.

Duct smoke detector.

One unit can accommodate multiple installation footprints to overcome mounting constraints. An adjustable housing overcomes mounting constraints. Plug in tool free sampling tubes speed installation. Hvac duct smoke detection.

A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust. Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. Tool free plug in sampling tubes speed and simplify installation. The duct smoke detector samples air for early detection of smoke and products of combustion present in air moving through hvac ducts.

Typical smoke detection devices used for duct application include smoke detector sensors within a housing mounted. Ventilation fan systems used to remove air from the inside of the building to the outside of the building. Nfpa 72 also states that a duct smoke detector is not allowed to replace an area smoke detector mainly because if the air handling unit ahu is not running the detector would not detect smoke. Therefore duct smoke detectors are typically considered mechanical equipment devices instead of life safety devices.

Duct smoke detection nfpa 90a code requirements there are exceptions to the two basic requirements. Duct smoke detection equipment a duct smoke detector is a device or group of devices used to detect the presence of smoke in the airstream of ductwork sections of the hvac air handling systems typically used in commercial buildings. The duct smoke detector is designed for use in duct applications where temperatures can exceed standard detector. Duct detectors aren t a replacement for room sensors.

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. Duct smoke detectors are a key component of fire detection and fire alarm systems.
