FireClass 701PH - Conventional High Performance Optical Smoke Detector - 516.900.002

The 701PH optical heat detector operates by sensing the optical scatter from
smoke particles generated in a fire, and a rapid rate of rising temperature increases
the smoke detection sensitivity for normal ambient conditions, the high performance
optical detector behaves as a normal optical detector. The micro-processor inside
the detector allows for threshold compensation, meaning the detector will adjust
sensitivity levels to compensate for dust and dirt levels in the chamber, resulting in
fewer unwanted alarms and an extended detector life.

The 701PH is approved to EN54-29, a multi-sensor standard for smoke and heat.
