How to connect the Device and Audio Loop circuits
The audio loop may be commissioned once the device (analogue) loop has been satisfactorily powered up
with addresses allocated to all the devices on loop circuits. The Audio loop wiring is routed from the control
panel with connection to each micro-DAU and Mains Powered DAU on the associated loop with return
connection at the panel, that is Audio loop 1 is used with Device loop 1 and Audio loop 2 is used with Device
loop 2.
