The AW-FD704EX Explosion-Proof UV/IR³ Flame Detector is a high-performance fire detection device engineered for hazardous industrial environments. Integrating four spectral ranges—UV (185–260 nm) and IR (3.8 µm, 4.3 µm, 5.0 µm)—it ensures precise flame detection with a rapid response time of ≤5 seconds. Its patented signal processing algorithm effectively suppresses false alarms from sources like sunlight, welding, and lightning. With a detection range of up to 60 meters and a wide 120° field of view, it offers extensive coverage. The detector's robust construction, featuring a cast aluminum or stainless-steel housing, meets IP66/IP67 protection standards, making it suitable for challenging conditions. Additional features include lens contamination self-check, adjustable sensitivity settings, and support for multiple communication protocols, ensuring reliable and flexible integration into various safety systems.

Applications
-
Oil & Gas
This sector is one of the most high-risk environments for fire and explosion, making ATEX smoke and heat detection indispensable.
- Installed in living quarters, control rooms, compressor rooms, and helidecks to detect smoke from electrical faults or equipment overheating.
- Deployed in processing units, control buildings, and storage tank zones where flammable gases and vapors are present.
- Positioned near valves, fuel pumps, and gantries to provide early warning in case of leaks or combustion.
-
Manufacturing and Processing Plants
Facilities that process volatile chemicals require continuous air monitoring and reliable early fire detection.
- Solvent Storage Rooms: Detect smoke from spontaneous combustion or faulty electrical equipment.
- Reactor & Mixing Areas: Placed above or around reactors where exothermic reactions may cause overheating or fires.
- Cleanrooms & Laboratories: Sensitive enough to detect smoke without disrupting delicate operations; certified enclosure ensures safe installation in explosive environments.
-
Industrial Manufacturing & Fabrication
Many manufacturing operations involve combustible materials or high-voltage equipment.
- Prevents ignition of aerosolized paints and solvents.
- Used near extrusion machines or chemical mixing areas where fumes and particles can become ignition sources.
- Detects overheating or smoke from spark-prone processes.
Why Choose This dual ATEX Smoke & Heat Detector?
Equipped with both photoelectric smoke sensing and thermal detection, the AW-CSH831EX-4W offers a comprehensive approach to fire detection. This dual-sensor technology enables the detector to promptly identify both smoldering fires and rapidly growing flames, ensuring timely alerts and responses.
With a smoke response threshold ranging from 0.10 dB/m to 0.27 dB/m, the detector offers precise sensitivity to smoke particles, enhancing its ability to detect fires at an early stage.
Energy Efficiency and Versatile Integration
Operating at 24V±2V DC with a monitoring current of ≤60μA and an alarm current of ≤30mA, this detector is designed for energy efficiency. Its low power consumption makes it an ideal choice for facilities aiming to reduce energy costs without compromising safety.
The detector features both Normally Open (NO) and Normally Closed (NC) passive contact outputs, allowing for flexible integration with various alarm systems and control panels. This versatility ensures that the AW-CSH831EX-4W can be seamlessly incorporated into existing safety infrastructures.
