Tool-free, plug-in sampling tubes speed and simplify installation. NFPA Standards and 90A should also be refer-enced for detailed information. The flexible housing of the duct smoke detector fits multiple footprints from square to rectangular. Innovation is our way of life. We design fire, carbon monoxide and heat detection and notification devices that use the most innovative technologies in the most inventive ways.
We Have Almost Everything on eBay. Smoke introduced into an air duct system will be distributed throughout the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct. The detector housing shall be UL listed per UL 268A specifically for use in air handling systems.
A plug-in duct sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. As with our duct smoke detectors , all duct smoke detector accessories are ULC listed. Ordering Information Part No. Fire situations may cause an interruption of power.

Furthermore, intentions for using duct smoke detectors should not be a substitute for area smoke detectors. Nor should it serve as an early warning detection system. Therefore, they should complement the buildings fire detection system and not serve as the primary fire detection system.
Because the detector mounts to round or rectangular ductwork, it is indispensable for Building Automation Systems, BAS, and HVAC applications. WARNING: Duct smoke detectors have specific limitations. Refer to NFPA and 90A for additional duct detector application information. If you do not wire the resistor through each of the detectors supervisory contacts, you are not monitoring the status of the detector itself.
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 (included). The difference in air pressure between the two tubes pulls the sampled air through the sensing chamber. NOT a replacement for a building’s regular fire detection sys-tem.
NOT a substitute for early warning detection.
