1. Product Overview
The JSY-F401-A is an ATEX-certified multi-spectral flame detector designed for reliable early fire detection across multiple fuel types.
Featuring triple-IR sensors with sapphire optical filtration, the detector delivers exceptional response to various flame types. Its advanced signal processing combines time-frequency domain analysis with proprietary Fourier algorithms to effectively distinguish real fire signatures from ambient light/thermal noise. The robust multi-sensor design ensures stable operation in extreme conditions (-40°C to +85°C, 95% RH) while minimizing false alarms in challenging environments.

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. |
