ZM4 offers the screw terminal port 'Tel. Paging' for emergency or other important announce‐
ments. Connect the shielded audio cable to the 'COM' terminal, ground wire to 'GND' and the
circuit breaker to release announcements to 'HOT' and 'GND'. So the audio signal is perma‐
nently present on the 'COM' terminal and closing the breaker superimposes all other channels.
