    Guard Locking switches if tripped require that both the fault be cleared AND a functional test of the Guard Lock.

    Guard Lock Switch can become faulted if someone attempts to force open a locked door or uses the emergency escape release mechanism.

    1. Ensure door is closed.

    2. Reset GIS.

    3. Verify that no fault is present. Diagnostic code will remain.

    4. Lock door (if necessary).

    5. Unlock door.

    6. Open door.

    7. Close door

    8. Verify that no fault is present and there are no diagnostic codes.

    9. Lock door (if necessary).
