Heat Detectors

OpalTM Photoelectric Isolator Smoke Detector

The Opal NFX are fixed temperature analogue addressable sensors employing low mass thermistors and microprocessor technology for fast response and linear temperature sensing

The Opal NFX are fixed temperature analogue addressable sensors employing low mass thermistors and microprocessor technology for fast response and linear temperature sensing The sensing elements of all three heat sensors are panel controllable through the Advanced Protocol 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 detectors have 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.

Features & Benefits:
  • Tri colour LED offering red, green and amber colours
