2.5. Emergency Broadcast
Emergency broadcast is conducted by first setting the combinations of the Emergency Sequences, Output
zones (individual or pattern), and Control Output patterns as Emergency Broadcast Patterns, then activating
these patterns by pressing the key on the remote microphone or via the control input of the system equipment.
A maximum of 128 patterns can be set for the Emergency Broadcast Patterns.
A combination of the EV message (sound source) and its broadcast duration is set as a single phase for the
Emergency Sequences, each of which can contain up to 3 levels of phases. A maximum of 4 Emergency
Sequences can be set.

Note
An EV message is a short form of Electronic Voice Message. These messages are
recorded as audio files.
The separately created EV messages are registered using the Setting Software, and
each message is set to one of 3 types: Alert, Evacuation, and Reset depending on the
contents.
The Alert and Evacuation messages are used in emergency situation, while the Reset
message is used to notify that the emergency situation is over.
Sixteen kinds of EV messages can be recorded on the SX-2000SM's CF card.
Output zone pattern Multiple zones
Control output pattern Multiple control outputs
Output zone pattern is the one into which multiple
broadcast zones are grouped, so broadcast can be
made to multiple zones simultaneously by activating only
one pattern.
Similarly, control output pattern is the one into which
multiple control outputs are grouped. This control output
pattern can be used, for example, to activate multiple
control outputs in synchronization with the emergency
broadcast.
To use the emergency broadcasting function, follow the procedures below to perform each setting using the
SX-2000 Setting Software.
Set the emergency broadcasting function to "Used."
Perform this in the "Basic settings."
Register the EV messages.
Perform this in the "System settings (System manager)."
