FireClass 701PH Conventional Optical and Heat Enhanced Detector

16.00 ex VAT


Product Code 



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