1.Product Overview
The JSY-F301-A, a two-infrared flame detector dedicated for tunnels, is an explosion-proof multi-spectral flame detector, suitable for various fuel types and can provide early warnings.
This detector is equipped with two infrared wavelength sensors, an ultraviolet sensor, and a sapphire optical filter. It has a very high response characteristics to a variety of fuel types of combustion flame,Tthe detector for the collection of multiple signal data, through the unique time domain, frequency domain signal processing and Fourier fuzzy algorithm, combined with interference source logic comprehensive judgment processing, to eliminate the interference of ambient light, thermal body radiation, can maximize the suppression of false alarm. Therefore, It is well suitable for applications in related environments such as indoor and outdoor open air where multiple false alarm sources exist.The special fire signal processing algorithm and multi-sensor technology have greatly improved the sensitivity of the detector, enabling it to operate in harsh industrial environments such as high/low temperatures and high humidity.

5.Indicator Lights
The JSY-F301-A 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. |
