DH100LP is a 2-wire photoelectric air duct smoke detector capable of sensing smoke in air velocities from 100 to 4,000 feet per minute (0.5 to 20.32 m/sec). this innovair features low-flow technology enabling duct smoke detection throughout a broad range of airfow environ - ments. many diffcult to solve hvac applications occur in low airfow duct applications where reliable smoke detection is critical. innovair with low-flow technology can detect smoke at air speed velocities of 100 feet per minute or greater, while continuing the same reliable performance to 4,000 feet per minute. the innovair family is designed for simplifed installation and easy maintenance. the modular construction allows for easy cleaning and uncomplicated feld replacement of the ul recognized power and sensor boards. warning: duct smoke detectors have specifc limitations. duct smoke detectors are: not a substitute for an open area smoke detector, not a substitute for early warning detection, and not a replacement for a buildings regular fre detection system. refer to nfpa 72 and 90a for additional duct smoke detector application information. model DH100LP 2-wire photoelectric duct smoke detector with low-flow technology product overview 2-wire low-flow duct smoke detector h v a c s y s t e m s m o n i t o r i n g
