Duct Smoke Detector Installation Detail

A wiring diagram is a simplified traditional pictorial depiction of an electric circuit.

Duct smoke detector installation detail.

The duct smoke detector is designed for use in duct. Smoke introduced into an air duct system will be distributed throughout the entire building. Nor should it serve as an early warning detection system. 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.

The duct smoke detector is equipped with an auxiliary relay. One unit can accommodate multiple installation footprints to overcome mounting constraints. Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system. Duct smoke detectors utilize 4 wire photoelectric technology for the detection of smoke.

Duct smoke detection may be useful in preventing injury and property dam age in instances such as the following. Patented tool free plug in sampling tubes. Duct detectors aren t a replacement for room sensors. 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.

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. It shows the components of the circuit as streamlined shapes as well as the power as well as signal links between the gadgets. Air velocity rating from 100 ft min to 4 000 ft min. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.

Tool free plug in sampling tubes speed and simplify installation. This detection method when combined with an. A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust. Furthermore intentions for using duct smoke detectors should not be a substitute for area smoke detectors.

Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. Duct preparation the duct detectors are designed for use in ducts where the air velocities are from 300 to 4000 feet per minute. Adjusts to square and rectangular mounting configurations. Variety of duct smoke detector wiring diagram.
