4-Wire Photoelectric, Low-Flow Duct Smoke Detector System Sensor’s Innovair DH100ACDCLP reduces the spread of smoke through HVAC air duct systems, including low-flow applications. As a photoelectric detector, it’s ultra-responsive to the large smoke particles commonly found in duct systems. The DH100ACDCLP uses low-flow technology to sense smoke in the lowest air speeds, from 100 to 4,000 feet per minute. When smoke is detected, all interconnected units will initiate their relays. However, to quickly locate the fire source, only the detector sensing smoke will alarm. Two DPDT Form-C relay contacts, connected to auxiliary equipment, can also be configured to prevent the spread of smoke through a particular area. Features • Photoelectric, low-flow technology • An air velocity rating from 100 feet per minute to 4,000 feet per minute (.5 meters per second to 20.32 meters per second) • Patented interconnectability for multi-fan shutdown • Two DPDT Form-C relay contacts The DH100ACDCLP is simple to install and maintain. Powered by 24 VAC/DC or 120/240 VAC, it can be easily mounted to round and rectangular ducts, from one to twelve feet in width, with outside mounting tabs. It also offers an adjustable telescopic sampling tube that can be used for duct widths up to 18 inches. This tube locks into place – no additional tools are necessary. Its modular construction allows for easy cleaning and field replacement of the power and sensor boards. Also simplifying maintenance is a transparent cover that provides convenient visual inspection. If the cover is removed, a patented cover-tamper trouble signal gives a 7-minute delay before the panel or remote accessory is notified of trouble. At a remote location, the remote test station option ensures that a detector is functioning properly and the remote sounder/LED indicator option signals if a detector is in alarm. However, the cover does not need to be removed if a detector needs to be reset at the detector. Simply push the built-in reset button. WARNING: Duct smoke detectors are NOT a substitute for open area smoke detectors, NOT a substitute for early warning detection and NOT a replacement for a building’s regular fire detection system. Refer to NFPA 72 and 90A for additional information. • 24 VAC/DC or 120/240 VAC • Versatile mounting options • Outside mounting tabs • A patented telescopic sampling tube • Modular construction • A patented cover-tamper trouble signal • A transparent cover • A remote test station • Remote sounder/LED indicator options • A built-in reset button Agency Listings Innovair Duct Smoke Detector Specifications Architectural/Engineering Specifications The air duct smoke detector shall be a System Sensor Model DH100ACDCLP Series Duct Smoke Detector.
