Product Overview

The InnovairFlex D4120 4-wire photoelectric duct smoke detector features 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 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 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.

Main Features

  • 4-Wire Photoelectric, integrated low-flow technology
  • Versatile mounting options: square or rectangular configuration
  • IncreasedWiring space with a newly added ¾" conduit knockout
  • 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
