3.2 Detector Window Contamination

It is important to keep the detector window clean and checks should be carried out at regular intervals –

determine locally according to the type and degree of contamination encountered – to ensure optimal

performance of the DRD-E flame detector. Although IR detectors can detect flames when the window is

contaminated, there may be a reduction of sensitivity.

3.2.1 Cleaning

If the window of the DRD-E flame detector is coated with dust or oil, the sensitivity to flames may decrease.

To remove the contamination, use a damp cloth; please ensure to remove any excess moisture with a dry

cloth.

NOTE: Do not wipe the main body of the detector window with alcohol or benzine.
