The System Sensor D4120W is the watertight InnovairFlex 4-wire photoelectric duct smoke detector. First, it senses smoke inside HVAC ducts and air handlers. As a result, it can shut down air handling during a fire event. In addition, it is UL listed as a watertight enclosure. Specifically, it guards the sensor against falling dirt, rain, windblown dust, splashing, and hose-directed water.
System Sensor D4120W key features
- Watertight InnovairFlex housing for wet or washdown environments.
- Multi-voltage 4-wire operation for conventional panels or standalone HVAC use.
- Plug-in photoelectric sensor head for easy service and better false-alarm immunity.
- Ample wiring space, a 3/4-inch conduit knockout, and built-in short-circuit protection.
- Controls up to 50 air handling systems when interconnected.
Operating conditions
The D4120W performs across tough duct environments. Specifically, it operates in airflow from 100 to 4,000 feet per minute. Also, it functions from -4°F to 158°F. Furthermore, it tolerates 0 to 95% humidity, non-condensing. Therefore, it suits commercial and industrial ductwork exposed to moisture.
