DAHUA WISUALARM DHI-HY-IF43DA-EX-GYXF - Flame detector, infrared point, RS 485, Relay output, FFT processing algorithm, Response time <10 seconds, 24 VDC
- SKU DHI-HY-IF43DA-EX
- Categoria CCTV Industrial > Incendio > Detectores
General Information
The DAHUA DHI-HY-IF43DA-EX-GYXF is a point infrared flame detector, ideal for industrial applications in hazardous environments. It uses a triple spectral band sensor (3.8 μm, 4.3 μm, 5.0 μm) to detect flames with high precision and interference immunity. It offers multiple outputs: RS485, 4–20 mA, and three relays (alarm, fault, and auxiliary). Its explosion-proof design and self-diagnosis functions make it reliable for petrochemical industries, tunnels, and paint plants.
Main Features
- Flexible installation: Uses a specific explosion-proof cast aluminum housing, with a 360-degree adjustable installation angle.
- Superior protection: Explosion-proof rating Ex d IIC T6, high resistance to electromagnetic interference.
- Intelligent algorithms: Intelligent composite discrimination of real flames, eliminating interference and reducing false alarm rates.
- High sensitivity: Maximum detection range of 60 m, emitting a fire alarm signal within 10 seconds.
Technical Specifications
- Model: DHI-HY-IF43DA-EX-GYXF
- Type: Point infrared flame detector
- Spectral range: 3.8 μm, 4.3 μm, 5.0 μm
- Sensitivity: 5 adjustable levels (3 by default)

- Operating voltage: DC 24 V (16–28 V)
- Operating current: Monitoring: <70 mA; Alarm: <80 mA; Defrosting: <300 mA
- Indicators: Alarm (solid red), Fault (flashing red), Monitoring (solid green)
- Outputs: RS485, 4–20 mA, three relays (alarm, fault, auxiliary)
- Operating temperature: –25 °C to +75 °C
- Relative humidity: ≤95% (non-condensing)
- Dimensions: 146 × 123 × 133 mm
- Weight: 1.55 kg (without mounting bracket)
- Mounting: Ceiling or wall
Includes
- Infrared flame detector DHI-HY-IF43DA-EX-GYXF
- User manual
- Warranty policy
