Point flame detectors are particularly useful in high-risk areas where fires can start rapidly, offering immediate alerts that enable swift responses.

4. Open-Path Gas Detectors

Open-path detectors work by emitting a beam of light across a monitored area and detecting changes in the beam when a specific gas is present. These detectors are ideal for large, open areas where gas may disperse widely, making fixed-point detectors less effective. Open-path gas detectors are highly sensitive and can monitor gases long distances, making them suitable for facilities with spacious layouts.

5. UV/IR and Multi-Spectral Flame Detectors

UV/IR detectors use a combination of ultraviolet and infrared sensors to distinguish between real flames and false triggers caused by hot surfaces or reflective materials. Multi-spectral infrared (MSIR) flame detectors are more advanced, using multiple infrared wavelengths to detect flames while minimizing false alarms accurately. These systems are invaluable in environments with potential interference, such as areas with welding equipment or high levels of particulate matter.
