Functions

Locking and unlocking

The door bolt locks automatically.
The door bolt is unlocked for several seconds when an electrical unlock impulse is
received. The duration is set via a DIP switch ("DIP switch S1 and S2", page 32).
If the door is opened within this time, the bolt remains in the unlocked state. The
door bolt locks again when the door is closed.
Fail-unlocked operation
The bolt is under electrical voltage in locked state.
If the door is closed, the maximum power is applied several times within 15
seconds. The door bolt then switches to a holding mode with reduced current
consumption to reduce the heating effect.
Fail-locked operation
The bolt is under electrical voltage in unlocked state.
The maximum power is applied several times within the set unlock period.

Monitoring sensors

Door and bolt statuses can be monitored electrically and used as a signal
generator for an alarm system or EAC system.
Depending on the connection type, not all sensors can be connected ("Control
input", page 33).
