HMS-FD-3IR uses high-quality multi-infrared sensing technology (MIR), using different wavelength infrared sensors with narrowband filtering, one of which works at the center wavelength reflecting the flame information, and the other two sensors monitor other infrared radiation in the environment, combined with the flickering characteristics of the flame, through high-performance microprocessor and good mathematical algorithm model for computational analysis, so that only the radiation spectrum that meets the flame characteristics will be confirmed as a fire alarm, False fire alarm signals formed by other interfering factors will be excluded.
• Uses high-quality multi-infrared sensing technology
• High-performance microprocessors and high-quality mathematical algorithm models
• High anti-interference ability, accurately identifying the radiation spectrum that matches the flame characteristics
• It has a good inhibition effect on interference such as sunlight, lightning, electric welding, artificial light sources, environment (people, etc.), heat radiation, electromagnetic interference, and mechanical vibration
• The detector alarm sensitivity is divided into four levels to meet the needs of different places.
