Flame detectors are line of-sight devices that look for specific types of light (infrared, visible, ultraviolet) emitted by flames during combustion. When the detector recognizes this light from a fire, it sends a signal to activate an alarm.
Flame detectors are best for protecting:
- Areas with high ceilings and open-spaces, such as warehouses and auditoriums.
- Outdoor or semi-enclosed areas, where winds or draughts can prevent smoke from reaching a heat or smoke detector.
- Areas where rapidly developing flaming fires can occur, such as petrochemical production, fuel storage areas, paint shops, and solvent areas.
- Environments that are unsuitable for other types of detectors.
