SYSTEM SENSOR D2 Duct Smoke Detector, 2-wire, Photoelectric

The SYSTEM SENSOR D2 duct smoke detector uses photoelectric sensing with integrated low-flow technology. It operates efficiently in air velocities ranging from 100 to 4,000 ft/min (0.5 to 20.32 m/sec).

Its modular design supports square or rectangular mounting. The detector features a patented sampling tube that installs without tools from either the front or back. It includes a cover tamper switch to signal trouble if the sensor cover is missing or improperly installed. Wiring space is improved with a 3/4 inch conduit knockout.
