IMPORTANT: If two alarm conditions exist at the same time, the highest priority alarm is
indicated. If two or more alarm conditions of equal priority exist at the same time, the
most recent one will be displayed.
IMPORTANT: The most recent alarms indicated by the device are logged for reference
by service personnel. This log is maintained even if the device is powered down or if
power is lost for any other reason.
IMPORTANT: If the mute button is pressed prior to an alarm condition (for example, to
mute the device in a movie theatre), critical high priority and high priority alarms will
override the mute function; medium and low priority alarms will be muted for eight hours
and twenty four hours respectively from the time the button was pressed. Press the mute
button off to display the last highest priority alarm. Press the mute button on again to
reset the eight-hour timer.
