1.Product Overview
JSY-F401-B is an explosion-proof multi-spectral flame detector. This detector is applicable to multiple fuel types and can provide early alarms.
The detector is equipped with three infrared wavelength sensors, one ultraviolet sensor, and a sapphire optical filter. It has extremely high response characteristics to the combustion flames of various fuel types. The detector processes multiple signal data collected through its unique time-domain and frequency-domain signal processing and Fourier fuzzy algorithm. By comprehensively judging and processing in combination with the interference source logic, it can eliminate the interference of ambient light and heat body radiation, and can maximally suppress false alarms. It is very suitable for indoor or outdoor open-air environments with multiple false alarm sources. The special fire signal processing algorithm and multi-sensor technology greatly improve the sensitivity of the detector, enabling it to work in harsh industrial environments such as high/low temperature and high humidity.

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. |
