1.Product Overview
The JSY-F401-B is an explosion-proof, multi-spectral flame detector designed for versatile fuel types, ensuring early fire detection.
Equipped with three infrared wavelength sensors, one ultraviolet sensor, and a sapphire optical filter, it excels at detecting combustion flames across various fuels. Leveraging a proprietary combination of time-domain and frequency-domain signal processing along with a Fourier fuzzy algorithm, the detector analyzes incoming data. By integrating interference source logic into its analysis, it effectively mitigates ambient light and heat radiation, minimizing false alarms. This makes it an ideal choice for both indoor and outdoor environments where false triggers are common. Thanks to its advanced fire signal processing algorithm and multi-sensor design, the detector maintains high sensitivity, performing reliably in tough industrial conditions, including extreme temperatures and high humidity.
2.Product Features
(1) Comprehensive Detection: Utilizes multi-frequency infrared, ultraviolet, time-domain, and frequency-domain analysis for accurate identification.
(2) Adjustable Sensitivity: Customizable settings on-site for tailored performance.
(3) Self-Learning Capability: Optimizes operation based on the environment.
(4) EMI Resistance: Resistant to electromagnetic interference for stable operation.
(5) False Alarm Prevention: Solar-blind design reduces unwanted alerts.
(6) Patented Design: Unique, industrial-grade appearance.
(7) Easy Installation: Field-of-view angle adjustment markings for quick setup.
(8) Robust Build: Dustproof, explosion-proof, corrosion-resistant, and rainproof.
3. Application
(1) Fire-Prone Areas: Ideal for environments with smokeless liquid and hydrocarbon fires, as well as locations at risk of deflagration.
(2) Energy Sector: Nuclear power plants, converter stations, and transformer areas.
(3) Manufacturing & Storage: Brewing and wine storage facilities, spray painting workshops, pharmaceutical plants, paint production/storage/transportation, chemical production/storage/transportation, and petrochemical sites.
(4) Industrial Settings: Power plant pump areas, machine rooms, and unattended zones; large factory warehouses storing flammable materials.
(5) Specialized Processes: Printing facilities (solvent handling, flattening, drying); chip production workshops.

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. |
