CNEX IIIC IIC Quad-Band UV IR Flame Detector -10°C~55°C Wide Temperature Range
1. Product Overview
This explosion-proof multi-spectral flame detector integrates 3 infrared wavelength sensors and 1 ultraviolet sensor, and is equipped with a sapphire optical filter. Relying on multi-spectral detection technology, it can accurately identify the combustion flames of various fuel types. Its built-in time-domain and frequency-domain signal processing systems, combined with Fourier fuzzy algorithms and interference source logic analysis, can effectively shield interference factors such as ambient light and thermal body radiation, greatly reducing the false alarm rate. It can operate stably in both complex indoor environments and open-air sites with numerous interference sources.
The detector adopts special fire signal processing algorithms and coordinates the collaborative work of multiple sensors, significantly improving detection sensitivity. Even in extreme industrial environments such as high/low temperatures and high humidity, it can quickly respond and achieve early fire warning, providing a reliable guarantee for safety protection.

5.Indicator Lights
| Status |
Indicator light |
| Operation Indicator Light (Green) |
Always on |
| Alarm Confirmation Indicator Light (Red) |
It flashes for early warning and stays on when in alarm. |
| Fault Indicator Light (Blue) |
When a fault occurs, the blue light stays on (and the red light goes out). When the device is powered on, it flashes, indicating the self-checking and self-adaptive status. |
