ALARM
The PA microphone can be used at any time because it is given the highest priority.
If the CPU failure indicator lights or flashes during the operation of the system, open the door and set the
computer control on-off switch to the OFF position. This permits attenuator-free all-zone broadcast to be
made using the PA microphone. (See p. 24.)
