Which observation helps to find the cause? · Company hall
Fixing a malfunction focuses on Ajax hub, detector range, zones and apprechten. Note when the problem started, which components were affected, and what changed shortly before that. Check the chain in sections and record where the operation is still present. Repeat the situation in which the error occurred after repair; a restart alone without a follow-up test provides insufficient certainty. We complete the check against tested detectors with appropriate user rights and demonstrable receipt of a test alarm.
