1. Product Overview
The JSY-F301-A is a two-infrared flame detector dedicated to tunnels. As an explosion-proof multi-spectral flame detector, it is suitable for various fuel types in the petroleum industry and can provide early warnings.
Equipped with two infrared wavelength sensors, an ultraviolet sensor, and a sapphire optical filter, this detector has a high response to combustion flames from various fuel types in the petroleum industry. It collects multiple signal data and, through unique time-domain and frequency-domain signal processing, as well as the Fourier fuzzy algorithm, combined with comprehensive judgment and processing of interference source logic, eliminates the interference of ambient light and thermal body radiation, maximizing the suppression of false alarms. Thus, it is well-suited for petroleum industry environments with multiple false alarm sources, both indoor and outdoor. The special fire signal processing algorithm and multi-sensor technology have significantly improved the detector's sensitivity, enabling it to operate in harsh industrial environments such as high/low temperatures and high humidity in the petroleum sector.

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. |
