Watertight 4-Wire Low-Flow Duct Smoke Detector The System Sensor DH100ACDCLWP Watertight Innovair™ is a NEMA 4 duct smoke detector rated for installation and use in non-hazardous indoor and outdoor applications. Features • NEMA Type 4 UL listed for non-hazardous indoor and outdoor applications • Air velocity rating from 100 to 4000 feet-per-minute (0.5 to 20.32 m/sec.) • Patented interconnectability for multi-fan shutdown (up to 10 air handlers) • Patented telescopic sampling tube • Patented cover tamper trouble signal • 24 VAC/DC or 120/240 VAC operation • High-Low voltage barrier • Equipped with two DPDT Form C relay contacts • Built-in reset button • Outside mounting tabs • Easy and quick mounting to round or rectangular ducts from 1´–12´ (0.3–3.7 meters) wide • Easy to clean • UL recognized field-replaceable power and sensor boards • Remote test station option • Remote sounder option • UL 268A listed Agency Listings 3240-1653:119 The DH100ACDCLWP can be directly mounted to rooftop HVAC equipment or used in other environmentally harsh applications that fall within its specified temperature limits. Since the unit is NEMA 4 rated, no additional enclosure is needed. The Watertight Innovair provides the same form, fit and wiring terminations as the standard Innovair but meets the NEMA 4 requirements, providing unsurpassed environmental protection. In addition to being the only watertight duct smoke detector on the market, the revolutionary Innovair solves many difficult low airflow duct applications where reliable smoke detection is critical. Innovair with Low-Flow technology can detect smoke in air speed velocities as low as 100 feet-per-minute or as high as 4,000 feet-per-minute. The Innovair family is designed for simplified installation and easy maintenance. The modular construction allows for easy cleaning and simple field replacement of the UL-recognized power and sensor boards. System Sensor has again set the standard for HVAC smoke detection technology. WARNING: Duct smoke detectors have specific limitations. DUCT SMOKE DETECTORS ARE: NOT a substitute for an open area smoke detector. NOT a substitute for early warning detection. NOT a replacement for a building’s regular fire detection system. Refer to NFPA 72 and 90A for additional information about the proper application of duct smoke detectors. • 3 year warranty S911 The DH100ACDCLWP is UL listed as a watertight enclosure providing protection against falling dirt, rain, windblown dust, splashing and hose directed water. Additionally, this detector features advanced Low-Flow technology, capable of sensing smoke in air velocities from 100 to 4,000 feet-per-minute (0.5 to 20.3 meters-per-second). 199-01-E 2091 NOTE: To maintain the watertight properties of this duct smoke detector, watertight conduit and fittings must be used. Mount the product with the conduit holes facing downwards, if possible.
