Verify alignment, latching, closing, egress-side operation, door swing, and required clearances under normal conditions before attributing a mechanical problem to software.\nTrigger one condition at a time. Observe the actual lock and latch, the person’s ability to use the approved egress method, local indications, access events, fire/life-safety status, and remote monitoring.\nTest combined and restoration states. Exercise the approved sequence when two material conditions overlap, then prove that restoration does not relock, suppress an alarm, or clear an event prematurely.\nRecord discrepancies by opening. Capture expected versus actual behavior, time, witness, evidence, corrective owner, retest, and approval. A global “doors tested” checkbox is not adequate.\n\nKeep the approved matrix with the as-built record and controlled operating instructions. Revalidate after lock, power-supply, controller, reader, request-to-exit, fire-interface, schedule, firmware, or door-hardware changes. Also test after unexplained unlocks, failed releases, door work, or emergency-plan changes. The objective is a door that preserves the approved balance of entry control, egress, fire/life-safety operation, and auditable restoration in every state the site depends on.\n\nOfficial references\n\nUL Solutions, Proper Application of UL Standards for Controlled or Delayed Egress Locking Devices—UL 294 & 1034, March 5, 2021.\nNFPA, free online access to NFPA 101, Life Safety Code; use the adopted edition and project-specific approval.",
