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 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.
