Before starting the job, take the proper work permit and inform to all the respective departments. Then do force the respective logics or interlocks if any (like fire suppression systems activation etc)

Prior to testing of Flame Detector we should check LED Visibility of the Flame Detector. It should be blinking green. This can be seen on the flame Detector.

Check the + 24 Volts DC Supply of the Flame Detector between + and – terminal of the Flame Detector.

Take UV / IR Testing Torch for testing of Flame Detector.

Before applying UV / IR rays to the Flame Detector, clean the detectors display by cotton cloth. It should be always cleaned for detecting the UV / IR rays. Otherwise Fault LED indication appears.

Apply the UV /IR rays from UV / IR torch to the Flame detector.

Resolution can be adjusted for the torch for checking the detector from short and long distance.

After 3 seconds alarm appears and hooter is activated.

Flame detectors Red LED indication will be ON (steady Red).

Acknowledge the Flame detector’s alarm & silence the hooter.

Note down the alarm tag and descriptions from the HMI or workstation. The alarm details must match with the flame detector tag number and installed location.

Confirm the flame detector activation status from the respective graphics page. You have to visually identify the color change signals of the respective flame detector on the graphics.
