Flame Detection units are optical devices, designed to ‘see’ flaming fires in a specified risk area. (such as a waste bunker or item of machinery)
Flame detection is usually installed in high risk applications where flaming fires may be expected and speedy detection is essential. Flame detection will respond immediately to the presence of a flame but will ignore the presence of smoke/heat. They are extremely resistant to false alarms and are robust and reliable.
Flame detectors look for the specific frequencies of UV (Ultra Violet) and/or IR (Infra-Red) radiation to detect a flaming fire.
The radiation produced by flames fall within a unique range of frequencies/wavelengths – the detectors only operate within these ranges to help eliminate the risk of false alarms.
The key points you need to know are:
Flame Detection is a reliable and cost-effective solution for protecting open risk areas at waste recycling facilities. They are commonly used for activating automatic fire suppression systems.
Flame Detection is not always suitable for the protection of waste recycling process lines. The speed that the material moves at through these areas means that the detector could be unable to spot the fire before it has passed – going on to cause more damage further down the line. Ember/Transit detectors are best for process areas.
