5.12. Connecting Analog Input Devices

The AMC-4W has eight analog inputs, for example, for potential free lock
mechanisms or to detect if a lock is closed or open. The AMC-4W can also
detect the wiring conditions 'short circuit' and 'broken' and initiate an alarm if
the appropriate devices are connected.
