The standalone controllers (and convertibles in controller mode) using the auxiliary input and output provide various Solutions/Applications:

Integration with Alarm Panels
The auxiliary relay can be connected to an alarm panel as a key-switch for arming-disarming purposes, within the controllers. Specific users can be assigned to activate the auxiliary relay.
Operation:
Creating user using menu 7, and then assigning the user to the auxiliary relay (menu 9), then setting the auxiliary relay to follow a valid user code (menu 6).

Door Forced
In this mode, the auxiliary input functions as a door monitor and is wired to the magnetic contact switch on the door. The auxiliary relay is to be wired to the alarm system or to a siren. If the door is forced open, the controller will wait for the period of the forced door delay time to elapse and then, it will activate the auxiliary relay.
Operation:
Auxiliary input and output settings configure the input behavior and the forced door delay period to activate the relay.

Door Held Open
In this mode, the controller can trigger the auxiliary relay, if it detects that the door has been held open (ajar) for longer time then the configured timer. In this mode the auxiliary input functions as a door monitor switch and is wired to the magnetic contact switch on the door.
The auxiliary relay is to be wired to the alarm system or directly to a siren. If the door is opened, the controller will wait for the door ajar delay time to elapse and if the door does not close prior to the end of this period, the controller will activate the auxiliary relay.
Operation:
Auxiliary input and output settings define the input behavior and the door-ajar time to activate the relay.
In addition to that, if the BL-D40 External Sounder is connected in the system and a door-ajar event occurs, the sounder will chime every few seconds until the door is closed.

Shunt
The standalone controller is capable of shunting an alarm system event.
Without a valid code entered, the auxiliary relay will match the condition of the magnetic contact switch; if the door opens, the auxiliary relay will open; if the door closes, the auxiliary relay will close.
When a valid code is entered, a countdown for maximum shunt time, as defined by the auxiliary setting, begins; if the door is not closed before the maximum shunt time, alarm will be triggered.
Operation:
The auxiliary input is to be wired to the magnetic contact switch on the door. The auxiliary relay is wired to the alarm system.
