Multi-Criteria Sensors

Opal™ Multi-Criteria Detector

The Opal multi-criteria, multi-sensor, photo, thermal detectors uses thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and faster response to a wide range of incipient fires.

The Opal multi-criteria, multi-sensor, photo, thermal detectors uses thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and faster response to a wide range of incipient fires. The plug-in unit combines two separate sensing elements that are managed by embedded software to act as a single unit. The Opal NFX-SMT2 conforms to EN54-7, a 58°C fixed temperature and rate of rise thermal assistance conforming to EN54-5.

The thermal detection function combines thermistor technology with a software corrected linear temperature response. In areas where the normal daytime activities may potentially create unwanted alarms, the detector can be programmed to operate in a “heat only” mode, automatically reverting to full photo-thermal operation during unoccupied periods. The sensing elements of the Opal NFX-SMT2 are panel controllable so the sensitivity thresholds of each element can be changed by the panel offering the ability to customise the device for the changing use of the area it is protecting. The detector has two integral tri-colour LEDs that provide 360° local visual indication of the device status. The LEDs are programmable with static or blinking red, amber and green status indications available
