The Opal photoelectric smoke detector features a completely redesigned detection chamber, developed through extensive research and development. This innovative design delivers faster response times, reduces sensitivity changes caused by settling dust, and minimizes false alarms caused by insects or other debris.
The plug-in detector incorporates advanced processing circuitry with smoothing filters to reduce unwanted alarms from transient environmental conditions. Embedded software runs complex algorithms that enhance detection speed while improving resilience against false alarms.
The NFXI-OPT includes built-in short-circuit isolation and two tri-colour LEDs that provide 360° local visual status indication. LED behaviour is programmable, allowing static or blinking red, amber, and green signals.
