18. External Input Interlock Function
NOTE
● Only available when the optional BRP7A5* Digital Input Adapter is connected.
● In case there are communication problems or the adapter is not working correctly, the External
Input Interlock menu will not be visible in the Service Settings menu.
● When a second remote controller is connected, it is not possible to use the BRP7A5* Digital
Input Adapter.
● When a BRP7A5* Digital Input Adapter is connected, the schedule function will be disabled as
long as the BRP7A5* Digital Input Adapter is connected.
For more information about the schedule functionality, refer to the operation manual.
● When a centralized controller is connected, the External Input Interlock function can be
overruled by the centralized controller. The centralized controller has priority and works like
there was no BRP7A5* Digital Input Adapter connected.
● Please make sure that the BRP7A5* Digital Input Adapter and the optional contacts (window
contact and key card contact) are correctly installed. Don't forget to confirm that the "No Volt"
contact on the BRP7A5* Digital Input Adapter PCB is in the correct position.
● For installation and connection of the BRP7A5* Digital Input Adapter refer to the corresponding
installation manual.
