Their linear response allows these sensors to be used to signal temperatures over the range of 58°C (Class A1S) to 78°C (Class BS)

The unit is designed to fit to the Standard Base (YBO-R/3(RED) or the Isolator Base (YBO-R/SCI)

Notifier NFXI-OPT Opal Addressable Smoke Detector photoelectric smoke sensor you can always rely onThe Opal photoelectric smoke detector has a completely new detection chamber design, the result of many years of research and development. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from ingress of insect and other debris. The plug in unit uses sophisticated processing circuitry that incorporates smoothing filters to help eliminate transient environmental noise
