2.3. Failure Output Patterns
failure output patterns are used to indicate the locations of failures when detected. up to 315 patterns can be
created for equipment, amplifier, speaker and power supply systems, and several failure sources can be set
per pattern.
[Method to indicate a failure]
Assigning the failure Output Pattern to the remote microphone's function key causes the failure lED to light
and the built-in buzzer to sound when a failure included in the pattern occurs.
One control output can be set in the failure Output Pattern and is turned ON when a failure included in the
pattern occurs. using this control output permits visual indication such as lamp to light for an external failure
indication.
use the Pc software to create failure output patterns. for details, refer to p. 7-51 .
for details on operations and indications when failures are detected, refer to p. 5-34 .

[EV Broadcast]
• If the assigned EV messages are the same, the message is broadcast to every zone set in all recalled
patterns.
• If the assigned EV messages are different, but the recalled pattern output zones are duplicated, the EV
message assigned the highest priority is broadcast to all duplicated zones, while other recalled messages are
broadcast to the corresponding output zones that are not among the duplicated zones.
