CEP HISTORY MODE OPERATION AND DISPLAY
NOTE
•
When an extinguisher is electrically fired (called an event), data is stored which
can give information on the status of the CEP prior to the event, the status of CEP
after the event, and the cause that triggered the event. History data for 15 events
can be stored at one time. If more than 15 events occur, the oldest event is erased
to make room for the newest event.
•
Wait at least 10 seconds after the last extinguisher is discharged before attempting
to review CEP History. Failure to wait 10
seconds could cause the CEP to give
erroneous result.
•
Only manual discharges that are initiated from the CEP are recorded in CEP
History. All automatic discharges are recorded, including those generated through
the application of the M88 FOV AFES Test Set.
1.
Press and hold BIT/LAMP TEST switch (Figure 4, Item 2).
2.
Press MAINT switch (Figure 4, Item 1) while still holding BIT/LAMP TEST switch (Figure 4, Item 2).
Pre-event information will be displayed for the most current event.
3.
While still holding BIT/LAMP TEST switch (Figure 4, Item 2), release MAINT switch (Figure 4, Item 1).
Post-event information will be displayed for the most current event (Table 2).
4.
Repeat Steps 2 and 3 to display additional events. If there is no event to display, then all LEDs will blink
(Table 2).
5.
Release BIT/LAMP TEST switch (Figure 4, Item 2) and the MAINT switch (Figure 4, Item 1) to perform a
BIT, followed by normal operation.
Table 2.
Pre- and Post-Event Information.
Pre-Event Information
Post-Event Information
All LEDs on CEP will be in same state as they were
immediately prior to the event.
If a Sensor LED is on, it indicates a corresponding
sensor generated a fire signal that caused the event.
If all Sensor and EXTINGUISHER LEDs on CEP are
blinking (SYSTEM ON and CEP FAULT on solid),
there are no further history events recorded.
If CEP FAULT LED is turned on, it indicates a MECH
MANUAL DISCHARGE switch was activated, causing
the event.
If SYSTEM ON LED is turned on, it indicates a ENG 1
MANUAL DISCHARGE switch on CEP was activated,
causing the event.
All EXTINGUISHER LEDs on CEP will be in same
state as they were immediately after the event.
