Watertight 4-Wire Photoelectric Duct Smoke Detector The InnovairFlex™ Series are the only duct smoke detectors flexible enough to fit configurations from square to rectangular and everything in between. Features • NEMA Type 4 UL listed for non-hazardous indoor and outdoor applications • UV Resistant, UL listed housing and cover material • Photoelectric, integrated low-flow technology • Air velocity rating from 100 ft/min to 4,000 ft/min (0.5 m/s to 20.32 m/sec) • Versatile mounting options: square or rectangular configuration • Plug-in sensor offers superb false alarm immunity and the latest sensor technology • Broad ranges for operating temperature (–4°F to 158°F) and humidity (0% to 95% non-condensing) • Patented sampling tube installs from front or back of the detector with no tools required • Increased wiring space with a newly added ¾-inch conduit knockout • One easy-access Test/Reset button and improved LED status • Patented interconnect feature for multi-fan shutdown • New high contrast terminal designations • Built-in short circuit protection from operator wiring errors • Field selectable settings for configuring the detector • Two DPDT Form-C relay contacts • 24 VAC/DC or 120VAC • Backward compatibility with existing Innovair products, including remote accessories Agency Listings The InnovairFlex D4120W watertight 4-wire photoelectric duct smoke detector is UL listed as a watertight enclosure providing protection against falling dirt, rain, windblown dust, splashing and hose directed water. D4120W duct smoke detector features a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of –4°F to 158°F, and a humidity range of 0 to 95 percent (noncondensing). A plug-in sensor head offers superior false alarm immunity. These features, plus a NEMA 4 rating, allow operators to mount the detector to rooftop HVAC equipment or use the detector in other harsh environments. The new design provides the same form, fit, and wiring terminations as the standard InnovairFlex unit. Superior test and operational features added to the standard model are also available in this watertight unit. As the only watertight duct smoke detector on the market, D4120W provides unsurpassed environmental protection while simplifying installation, testing, and maintenance. This InnovairFlex duct smoke detector can be customized to meet local codes and specifications without additional wiring. The new InnovairFlex product line is compatible with all previous Innovair models, including remote test accessories. WARNING: Duct smoke detectors are NOT a substitute for open area smoke detectors; 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. NOTE: To maintain the watertight properties of this duct smoke detector, watertight conduit and fittings must be used.

Important Interconnect Notes • When using the interconnect feature, all interconnected units must be powered using the same independent supply. • Polarity must be maintained throughout the interconnect wiring. Connect the INT+ terminal on unit 1 to the INT+ terminal on unit 2 and so on. Similarly, connect the INT/AUX– terminal on unit 1 to the INT/AUX- terminal on unit 2 and so on. • Up to 50 D4120W units may be interconnected. • Up to 10 DH100ACDC units may be interconnected. Please note that each of the 9 DH100ACDC units interconnected may be replaced by three D4120W units. Therefore, when using the interconnect feature a single DH100ACDC can drive either 9 DH100ACDCs or 27 D4120W units. * NOTE: Alarm can be reset only at the initiating device and not at the devices interconnected. A05-0420-000 Accessories System Sensor provides system flexibility with a variety of accessories, including two remote test stations and several different means of visible and audible system annunciation.
