7.3 Repair

Problem

The flame detector does not activate an alarm during the performance check.

Remedy

Ensure that the flame detector is registered on the control panel.

If the problem persists:

Ensure that the protective glass on the flame detector is clean and the sensors

are clearly visible. Clean the protective glass if this is not the case.

If the problem persists:

Replace the flame detector.
