5.3.8 Emergency Signal
Input 2 is designed to broadcast an Emergency Evacuation Message (EEM), overriding the discussion in the event of an
emergency. Connect a switch (normally-open) must be connected to the emergency switch connector. When the switch
is closed an "Emergency Evacuation Message (EEM)" audio signal present on the 'In 2' input is distributed to all output
channels, overriding all other audio inputs.
Note: There is no level adjustment for input 2. The level of the signal must be controlled externally.
