Alarm Priorities
Apollo alarms are organized into three categories
based on urgency:
Figure 100. Alarm DisplayAlarm Indications
Alarms are indicated to the user in three ways:
• a color-coded alarm message is displayed in
the status field on the screen (1 in Figure 100)
• the LED alarm indicator lights up (2 in Figure
100)
• an acoustic tone is annunciated (see below)
If alarm limits are violated, the corresponding
measured values on the screen will be highlighted on
a colored background (3 in Figure 100) and will flash
on and off. The colored background will reflect the
color-coding of the alarm priority (red, yellow, white).
The specific way each alarm type is indicated is as
follows:
