System Sensor D2 2-Wire Photoelectric Duct Smoke Detector

The SYSTEM-SENSOR-D2 2-wire photoelectric duct smoke detector senses airflow speeds ranging from 100 to 4,000 feet per minute with proven System Sensor precision.

The enhancements built into the D2 improve false alarm immunity (with plug-in sensor head); broaden operating temperature (4F to 158F) and humidity (0 to 95 percent noncondensing) ranges; while simplifying installation and maintenance. These advance features can detect smoke even in the harshest duct applications.

The D2 duct smoke detector has signals to indicate trouble and maintenance conditions. Additionally, a cover tamper feature is incorporated to indicate a trouble condition for removed or improperly installed sensor cover.

The D2 eatures a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular duct work.
