InnovairFlex™ D4120 4-wire photoelectric duct smoke detectors feature a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 ft/min, temperatures of –4 °F to 158 °F, and a humidity range of 0 to 95% non-condensing. A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance. 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.
Features & Benefits:
Patented sampling tube installs from front or back of the detector with no tools required
Increased wiring space with a newly added 3/4 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
24V AC/DC or 120V AC
