This version has an internal timer to set re-locking time.

Fail safe.

The electric handle is disabled (idle) with the red LED turned on.

When the open button is pressed and released the LED turns green, the buzzer sounds if it has been enabled, and the handle allows the door to be opened. This state lasts for the time set on the timer (from 0 to 60 seconds), or until the handle is first activated. To open the door again it is necessary to press the open button once more.

The use of a door loop is recommended.
