What is the standard pin setup of the DigiAir Pro 3?
As standard, the device is triggered by removing or applying zero volts to input terminals 1-8. No external pull-up resistors will be required. This is usually achieved via the digital communicator outputs of a control panel.
If you need to use a positive applied/removed, you can toggle the pin bias via the MyBase app or contact technical support so that they can amend the bias of the device.
