Preparing for a Fire Alarm Inspection
Inspections validate design and installation. Thorough documentation and a self-check prevent failed inspections and costly delays.
Acceptance vs periodic inspections
Acceptance (commissioning) inspections verify a new or modified system before it is placed in service. Periodic inspections confirm ongoing performance over the system's life. Both rely on functional testing and records.
Documentation inspectors expect
Have the approved drawings, sequence of operation, battery and voltage-drop calculations, device records, and completed test documentation ready. Organized paperwork signals a well-managed system.
Common review items
Frequent items include coverage gaps, notification below performance goals, mislabeled devices, missing supervision, and incomplete records. A self-inspection against the approved design catches most before the AHJ arrives.
