5.7 DISPLAYING THE ALARM CAUSE
5.7.1 FUNCTION
In "FFCIF mode", the information for the zone in alarm is normally displayed. However, it
can be useful to know which circuit/point caused the alarm.
The LCD displays this information when the operator presses and holds the "POINT" key.
The time that the alarm occurred at and the alarm type are replaced by the circuit/point that
caused the alarm.
5.7.2 OPERATING SEQUENCE
To display the circuit/point that caused the alarm displayed, press and
hold the "POINT" key.
- The alarm time and type are replaced by the circuit/point that
caused the zone to go into alarm.
To restore the alarm display, release the "POINT" key.
- The alarm time and type are re-displayed.
NOTES: If the LCD is in FFCIF Type 2 mode, this keypress is invalid.
The FIP may be programmed to show a preview of the cause of the alarm on
the main alarm display instead of the alarm time. If this feature has been
enabled, when the "POINT" key is pressed the alarm time is displayed along
with the full alarm cause information.
F4000 V2.31 and later can be programmed to update the alarm cause text
whenever a new alarm cause is detected. They can also be programmed to
reannunciate a zone alarm when a new cause is received, i.e.
unacknowledge a previously acknowledged alarm, activate the alarm
sounder, and make the Master Alarm LED flash.
