Power Loss to the Safety Relay
When power is cut off to the Safety Relay only, the door will return to its normal mode, but requests from the Video Intercom to grant access do not get processed. When power is restored the Safety Relay returns to its last known state before the power loss. If the Safety Relay was in the lockout state before power was cut off, it returns to the lockout state. If it was in its normal state, it returns to the normal state.
