The SS-PROBE-D2 conventional photoelectric smoke detector features a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular duct work. This duct smoke detector senses airflow speeds ranging from 0.5 to 20.32 metres per minute with proven precision. The enhancements built into this model improve false alarm immunity (with plug-in sensor head); broaden operating temperature (-20 °C to 70 °C) and humidity (0 to 95 percent non-condensing) ranges; while simplifying installation and maintenance. These advance features can detect smoke even in the harshest duct applications.
The new design provides more wiring space with an added 20mm conduit knockout. Numbers and labels for terminal designations are consistent with previous models. The sampling tube can be clicked into position with one smooth motion from either the front or the back of the detector.
The SS-PROBE-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. An improved cover design, with an integrated low-flow feature, isolates the sensor head from the low-flow technology for simple maintenance.
The D2 series is designed for greater flexibility and reliable smoke detection to simplify installation and maintenance. The new product line is backward compatible to existing models, including remote test accessories.
