The air duct detector housings from Siemens Building Technologies' Fire Safety Division are specifically engineered for compatibility with the 11-Series detectors. These housings are intended for direct installation within heating, ventilation, and air conditioning duct systems, adhering to the National Fire Protection Association Standard No. 90A. When fitted with photoelectric detectors, these units are capable of detecting dangerous levels of combustion products or smoke traveling through the ductwork. It is important to note that air duct detectors should not be used as a replacement for open area detection systems.

Air duct enclosures may be fitted with optional relays. These relays are employed to activate additional equipment upon the detection of smoke or combustion particles.
