8.7.4. Clearing System Faults
If the fault condition is associated with an RLDS, the
monitor will return to normal operation soon after the
problem is corrected. At that time the yellow LED
will turn off and any external alarms connected to the
monitor's alarm relays will also turn off.
Once the system malfunction has been corrected, it
may take some time for the fault condition to clear
completely. If the fault is associated with a specific
zone, the RLDS must first cycle back to the affected
zone before it returns to normal operation. At that
time the yellow LED will turn off and any external
alarms connected to the monitor's alarm relays will
also turn off.
8.7.5. Viewing Fault Log
A data log of the last 20 fault conditions is retained in
memory. On the Fault screen ( Figure 8-6 ) select the
LOG option to view a display of the Fault Log:
This screen lists potential fault conditions in the left
column and displays a check mark indicating which
problems were associated with each fault

condition as represented by the vertical cursor bar. As
you move the bar horizontally using the left/right

cursor keys, the date and time the fault condition was

detected are displayed in the upper right hand corner
of the display window.
Anytime the fault status changes, there is an entry in
the fault log, both when the fault occurs and when it
is cleared.
The Fault Log can be reset by pressing a

combination of the ENTER and right arrow buttons
while viewing the log.
