1. Product Overview
This explosion-proof quad-band flame detector is engineered for early fire detection in environments with diverse fuel sources. By combining advanced infrared (three wavelengths) and ultraviolet sensing technologies, it precisely identifies combustion patterns across multiple fuel types, enabling faster alarm triggering.
The device integrates three IR sensors and one UV sensor, paired with a sapphire optical filter to create a comprehensive spectral monitoring system. It improves response times by over 30% for flames from hydrocarbons, alcohols, and other fuels. Its proprietary quad-band detection employs a multi-dimensional analysis framework, incorporating:
(1) Time-domain waveform profiling
(2) Frequency-domain spectral decomposition
(3) Fourier-based fuzzy algorithms
Coupled with an interference logic database, it eliminates >98% of false alarms caused by sunlight, welding arcs, and thermal radiation. Ideal for challenging settings like chemical plants and storage facilities.
Advanced sensor fusion algorithms and adaptive thresholding ensure consistent performance (≤15 sec response) under extreme conditions (-10°C to 55°C; 95% RH). Its enhanced sensitivity surpasses conventional detectors, delivering reliable 24/7 protection for high-risk areas.

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. |
