Restoring the Default Settings
Restore the default settings as follows:
1. The system is in a disarmed state (e.g. in revision mode).
2.
Remove the control unit cover. The plugs with the
LSN lines (3.4 and 7.8) must be removed from the control unit.
3. In the control unit, move the jumper from BR1 to BR2.
4. Close the tamper contact GK for at least 3 seconds until the yellow LED on the control unit is
deactivated and the buzzer emits a signal.
¨
All the keys and the customer code have now been erased.
The default settings have been restored.
5. In the control unit, move the jumper from BR2 back to BR1.
6. Reconnect the plugs with the LSN lines to the control unit and reset the LSN line malfunction
message on the control panel.
