Before you wire this

Code and jurisdiction vary. Locking and egress requirements differ by edition and authority — NFPA 101, IBC, and your local amendments do not always agree. This reference confirms only that your wiring matches a known-good electrical topology. It does NOT confirm that the locking arrangement is permitted at this opening. Whether a lock may be installed here — and how it must release on fire alarm, loss of power, and egress — is determined by the Authority Having Jurisdiction and the stamped, approved fire and life-safety design for the building.

If you are unsure how this door must behave in an alarm or power-loss condition, stop and confirm with your foreman or the AHJ before energizing.
