The SX-2000AO has a 24 V emergency cutoff
input terminal on the rear panel, allowing
control of an emergency audio input. When the
SX-2000 system is combined with an
emergency broadcast system, a 24 V DC is
normally kept being supplied to this
emergency cutoff input terminal and is cut off
(24 V emergency cutoff function) in emergency
situations. This interrupts the general-purpose
broadcast from the SX-2000 system, allowing
the emergency broadcast system to override it.
(For details, see the separate Installation
Manual, "Installation.")
Note
When the 24 V Emergency cutoff input is set to
be disabled (not usable) with the DIP switch 8
inside the protective cover, the Emergency
indicator will not flash even if 24 V DC supply to
this input terminal is cut off.
