Will the sliding glass door open automatically when the power is cut off?

The sliding glass door will not open automatically when the power is cut off. When the sliding glass door access control is powered on, there is a sensor inside that will automatically open and close the door. After the power is turned off, the sensor stops working and cannot sense external movements and will not automatically open or close the door. After a power outage, the door lock of the access control system will be normally open or normally closed, depending on the electric lock. If you use an electric lock that turns on and off when the power is off, the access control system will automatically open. Otherwise, the office access control system will still be locked and you will have to wait for power to open the door.
