Which observation helps to find the cause? · warehouse
Fixing a malfunction focuses on detector positions, zones, activation times and user codes. 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 a registered detection test per zone and a working notification for the designated user.
