Connect an emergency input line
You can use this input for emergency announcements and/or signals. This line is activated when the signal is above a
certain threshold (VOX). When the line is activated it has the highest priority and overrules all input channels.
The emergency line has it's own internal volume control and is not affected by the master volume. To set the
emergency volume, refer to the 'settings' chapter. If you use the emergency input make sure that the internal settings
are correct (refer to settings).
Note
The emergency input has a 24 V relay output (screw terminal), which is activated on the VOX of the input.
An additional 24 Vdc output (screw terminal) is available to power external relays.
