I. Infrared and ultraviolet flame detectors Features

Rapid response: High flame detection sensitivity, much faster than traditional temperature/smoke detection systems.
Non-contact detection: No need to be near a fire source, suitable for dangerous places such as high temperature, toxic, and explosive environments.
Low false alarm rate: AI algorithm + multi-sensor fusion effectively filters interference from sunlight, welding, vehicle lights, etc.
II. Installation Requirements for Infrared and ultraviolet flame detectors
1. Flame detectors should be installed so that the monitored area is within the effective range of the field of view.
2. The mounting surface of the flame detector should be firm and earthquake-resistant.
3. Install the detector away from high-temperature objects.
4. Flame detectors should be installed to avoid obstruction as much as possible. For obstacles with a horizontal or vertical dimension not exceeding 0.5 meters, the distance between the detector and the obstacle should not be less than 2.5 meters. For obstacles with a dimension exceeding 0.5 meters and which cannot be avoided, the number of detectors should be increased appropriately.
5. Flame detectors can be installed on walls, roofs, or fixed racks. The detector’s monitoring window should be tilted downwards at a 30-45 degree angle, so that it can look both downwards and forwards, reducing the accumulation of dust on the mirror surface.
6. The distance between the detector and the monitored target can be determined according to the characteristics of the fire, but is generally not less than 1.5m. The installation height of the detector is generally not less than 2.5 meters.
7. During on-site installation, in accordance with the requirements of GB/T 836.15-2024 standard, use cable entry devices and explosion-proof plugs that are suitable for the environment and have obtained explosion-proof certificates, and use high-temperature resistant cables;
8. Flame detectors typically employ a cross-protection method, which involves installing two detectors diagonally opposite each other. This avoids blind spots and provides backup in case one detector fails.
