MIWA AU type electric lock, unlocking the apartment manager's room

"I want you to open the door of the caretaker room that closed automatically."

The target is the condominium manager's room.When the caretaker was about to go home, he forgot the key and went out to lock it automatically.

The previous vendor seems to have put it on hold only with an estimate, saying that it cannot be opened without breaking it.

It opens outward and there is no smoke guard.It seems that there is no trigger latch, so it is a single stroke AU type.If so, is it solidified and the unlocking direction is the upward direction?

Thumbturn always in vertical position

Proceed according to the procedure, turn the thumbturn, and then lower the lever to unlock.No need to hold.

For types without a thumbturn, there are also AL types and hotel locks that can be unlocked by lowering the inner lever with a string.I proceed with the work judging from the outside, but when there is a door scope, I do not forget to check with the CCD camera.
