Duct Smoke Detector

Innovairflex duct smoke detectors combine an impressive collection of innovations designed to save you time and money and provide the flexibility you need in the field.
Duct smoke detector. Duct smoke detection nfpa 90a code requirements there are exceptions to the two basic requirements. Therefore duct smoke detectors are typically considered mechanical equipment devices instead of life safety devices. The duct smoke detector should be compatible with building automation and fire alarm systems. Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring.
The duct smoke detector samples air for early detection of smoke and products of combustion present in air moving through hvac ducts. These fans are excluded from the above requirements and. Duct detectors aren t a replacement for room sensors. Hvac duct smoke detection.
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. The duct smoke detector is designed for use in duct applications where temperatures can exceed standard 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. 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.
Tool free plug in sampling tubes speed and simplify installation. An adjustable housing overcomes mounting constraints. Ventilation fan systems used to remove air from the inside of the building to the outside of the building. One unit can accommodate multiple installation footprints to overcome mounting constraints.
Typical smoke detection devices used for duct application include smoke detector sensors within a housing mounted. A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust. 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.
