2.7 ALARMS
2.7.1
Alarm Control
When a pre-set alarm parameter is reached, e.g. the depth reducing, the
system raises an alarm automatically. In an alarm condition, the lower display
changes to highlight the cause of the alarm and flashes red and green
alternatively until the Enter Key is pressed twice. At which point all the FFDs
except the one on which Enter was pressed, return to normal. The audible
alarm, if fitted, is also silenced by this operation. After this, the lower display
continues to monitor the alarm condition. The alarm is still active and, if the
alarm parameter is again exceeded, the alarm will flash/sound as necessary.
The displayed alarm function remains on the lower display until Page is
pressed.
2.7.2
Alarm Types
The system incorporates the following types of alarm:
HI ALARM - This is initiated if the value of a function exceeds a pre-
set level.
LO ALARM - This is generated if the value of a function drops
below a pre-set level.
SECTOR ALARM - This is generated when the value of a function
leaves the safe sector as shown in Fig 2.2.
