Installation instructions
B-1993x
If a control signal is applied at I2 within the active leaf release hold-open time, the lock also retracts
the vertical rods of the top/bottom lock and moves to the fully open final position. The passive leaf
can now be accessed. Once the hold-open time has expired, the lock moves into its initial position
and the signal contact 1 closes.
4.3 Voltage loss during motor-driven operation
If the power supply fails during motor-driven actuation, the motor stops and the lock remains in its
current position.
The door leaf can still be opened at any time manually via the hardware.
