The Opal photoelectric smoke detector features a completely redesigned detection chamber, developed through extensive research and development. This advanced design provides faster response times, reduces sensitivity shifts caused by dust accumulation, and minimizes false alarms from insects or other debris.
The plug-in detector incorporates sophisticated processing circuitry with smoothing filters to suppress transient environmental noise that could trigger unwanted alarms. Embedded software runs advanced algorithms to enhance detection speed while improving immunity to false alarms.
The NFXI-OPT also includes built-in short-circuit isolation and dual tri-colour LEDs, providing 360° local visual status indication. LED behaviour is fully programmable, offering static or blinking red, amber, and green signals.
