The System Sensor D4120 is an 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 before smoke spreads through a building. In addition, the multi-voltage 4-wire design works on a conventional fire alarm system or as a standalone HVAC device. Specifically, a plug-in sensor head simplifies installation and testing.
System Sensor D4120 key features
- Pivoting InnovairFlex housing fits square or rectangular footprints.
- Plug-in photoelectric sensor head for easy service and better false-alarm immunity.
- Multi-voltage 4-wire operation for conventional panels or standalone HVAC use.
- 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 D4120 handles a wide range of 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 fits demanding commercial and industrial ductwork.
