System Sensor D4120W 4-Wire Photoelectric Duct Smoke Detector, Watertight


  • Also known as: BK-D4120W

  • The SYSTEM-SENSOR-D4120W watertight 4-wire photoelectric duct smoke detector senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of 4F to 158F, and a humidity range of 0 to 95 percent (non-condensing).

    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 D4120W provides unsurpassed environmental protection while simplifying installation, testing, and maintenance. The unit features a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular ductwork.
