An alarm condition generates audible and visual signals according to the alarm priority.
When an alarm condition occurs, the backlight switches ON (if OFF) until the alarm
condition ends. All audible and visual alarm signals are cleared when the alarm condition
ends.
Audible signal
Continuous tone or five
beeps (beep-beep-beep,
beep-beep with falling
tone) twice every
10 seconds.
Three beeps (beep-beep-
beep with falling tone)
every 20 seconds.
During multiple alarm conditions, the visual and audible alarm signals always indicate
the highest priority alarm. For example, if a medium priority alarm is present when a
high priority alarm occurs, the high priority alarm signals replace the medium priority
alarm signals.
When you press the Alarm Silence button to silence one or more alarms, the alarm LED
indicates the highest priority alarm condition. All other visual alarm indicators (flashing
value, dashed display, etc.) are displayed until the alarm condition ends.
If no alarms are present when you press the Alarm Silence button, the alarm LED is lit
yellow to indicate upcoming alarms will be silenced. If an alarm condition occurs while
alarms are silenced, the alarm LED indicates the priority of the alarm. All other visual
alarm indictors are displayed until the alarm condition ends.
