1.4.1 Detection Principles

The Model 40/40U and UB Flame Detector is an electronic device designed

to sense the occurrence of fire and flames and subsequently activate an

alarm or an extinguishing system directly or through a control circuit.

The UV Flame Detector is a single spectrum optical detector sensitive to the

UV radiation spectrum that is present in fires. The detector monitors the

protected volume, by measuring the radiation intensity in it, within the

frequency range of the electromagnetic spectrum, namely the Ultra-Violet

(UV).
