Malfunction inspection of idling thumbturn, Push-pull handle lock with GOAL GON type TME crime prevention thumbturn

"Sometimes I'm trapped"

There were times when the thumbturn would spin idle, and there were times when I was trapped indoors.From what I hear, I think it's a mistake in the operation of the TME type security thumbturn made by GOAL.

When I arrived at the scene, the front door was open. Apparently ALSOK opened it with a duplicate key. The push-pull grip handle lock that caught my eye has a rugged design that looks pretty solid. This type is seldom seen.

The thumbturn was still a TME security thumbturn.When I checked, it was in idle mode.

The operation itself is working normally, so it was an operation error.

I told her how to operate it in OJT, but after the work was completed, I received another call just before I left the apartment. It looks like she didn't understand how to do it.

I returned by elevator again and had her practice operation method repeatedly. She will be fine this time.
