Duct Smoke Detector Connection

It reveals the elements of the circuit as streamlined shapes and also the power and also signal connections between the devices.

Duct smoke detector connection.

A wiring diagram is a simplified traditional photographic depiction of an electric circuit. The detector assembly cover provides easy access to the smoke sensor its wiring connections sample and exhaust tube fittings and the smoke chamber itself. Duct detectors aren t a replacement for room sensors. Features 4 wire photoelectric integrated low flow technology air velocity rating from 100 ft min to 4 000 ft min 0 5 m s to 20 32 m sec.

Furthermore intentions for using duct smoke detectors should not be a substitute for area smoke detectors. The duct smoke detector is designed for use in duct. Therefore duct smoke detectors are typically considered mechanical equipment devices instead of life safety devices. 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.

How to installation air duct smoke detector. Therefore they should complement the buildings fire detection system and not serve as the primary fire detection system. A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust. Install the duct smoke detector on a flat section of hvac duct between six and ten duct widths from any bends or.

Air enters the detector s sensing chamber through a sampling tube ordered separately that extends into the duct and is directed back into the ventilation system through an exhaust tube. 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. Nor should it serve as an early warning detection system. Duct smoke detector the innovairflex series are the only duct smoke detectors flexible enough to fit configurations from square to rectangular and everything in between.
