Equipment operation upon failure detection
In this event, a failure of the contents shown on the LCD screen has occurred within the system. Pressing the
amplifier’s [OK] key to acknowledge the failure or acknowledging the failure by way of the Fireman’s
Microphone stops the buzzer and switches the yellow failure indicator from flashing to steady-on mode. (Refer
to "Failure Acknowledgement" on
page 54 ).
If the failure is reset at the amplifier, the failure indicator goes out. However, if the cause of the failure has not
been remedied, the unit will return to failure status. (Refer to "Failure Reset Operation" on
page 55 ).
