GENERAL OPERATION & DISPLAY (CONTINUED)
Once all alarms have been acknowledged, and then reset or isolated, the FIP restores the
display and keypad to the exact state before the alarm occurred. Consequently, partly
entered commands or numbers can be finished, or any recalls that were being done are re-
started.
5.1.2 FFCIF TYPE 3 OPERATION
When the FIP is displaying an alarm using an FFCIF in Type 3 Mode, the LCD displays the
following information:
(i)
The time at which the alarm occurred, or a preview of the cause of the alarm
(programmable).
(ii)
The zone alarm type.
(iii)
Whether the alarm is acknowledged or not (Figure 5.1 shows an unacknowledged
alarm).
(iv)
The total number of alarms and the sequence number of the currently displayed
alarm.
(v)
The zone number and location. The location may be a zone name, a detector name,
or a combination of both.
The F4000 FIP maintains a list of alarms in the order in which they occurred. In the absence
of operator intervention, the LCD display will show the first alarm. All alarms in the list can
be viewed, one by one, by pressing the "NEXT" or "PREV" keys.
Each alarm can be individually acknowledged when it is displayed by pressing the "ACK"
key. The text "ACKD" appears on the display whenever an acknowledged alarm is viewed.
Once an alarm has been acknowledged, it can be removed from the alarms list by:
(i)
Pressing the "RESET" key - all acknowledged alarms are RESET, and removed from
the list; or
(ii)
Pressing the "ISOLATE" key - all acknowledged alarms are ISOLATED, and
removed from the list; or
(iii)
The alarm condition being cleared from the detector on a non-latching zone.
