Faraday Air Duct Housings

The Faraday air duct detector housings are designed to be used with most Faraday smoke detectors that do not require a relay. Designed for installation directly to heating, ventilating and air conditioning duct systems they comply with National Fire Protection Association Standard No. 90A. When equipped with photoelectric detectors, these units will signal the presence of hazardous quantities of products of combustion or smoke being carried through the duct system. Air duct detectors are not intended to be a substitute for open area detection.
