Ex Point Type Triple-Band Flame Detector UV IR Multi-Criteria Judgment
1.Product Overview
This explosion-proof multi-spectral flame detector is designed for early fire warning across diverse fuel types. Equipped with dual infrared wavelength sensors, an ultraviolet sensor, and a sapphire optical filter, it delivers high responsiveness to combustion flames from various fuels.
To minimize false alarms, the detector processes multi-signal data through proprietary time-domain/frequency-domain analysis and Fourier fuzzy algorithms, combined with interference source logic judgment. This effectively eliminates interference from ambient light and thermal radiation, making it ideal for indoor/outdoor open environments with multiple potential false alarm sources.
Its advanced fire signal processing algorithms and multi-sensor technology enhance sensitivity, ensuring reliable operation in harsh industrial conditions such as extreme temperatures and high humidity.

5.Indicator Lights
The JSY-F301 flame detector is equipped with three status indicator lights, which are used to indicate its working status.
| Status | Indicator light |
| Operation Indicator Light (Green) | Always on |
| Alarm Confirmation Indicator Light (Red) | It blinks for early warning and is always on for an alarm. |
| Fault Indicator Light (Blue) | When a fault occurs, the blue light is always on (and the red light goes out). When the device is powered on, it blinks to show the self-checking and self-adaptive status. |
