indicated on the system. However, events for only point 0 will be logged
to the event history or to the printer, so as to not unnecessarily fill the
event history.
Fault indications for points are usually non-latching, i.e., when the point
fault is cleared, the fault indication will automatically clear.
Therefore, while it is usual to find zones and points in the Faults list, it is
possible to find only zones in the list, if all the point faults have cleared.
In this situation, the point that caused the zone fault can be determined
from the history log. See Chapter 4, Viewing the Event History.
This function requires Access Level 2.
To reset a latched fault indication:
Press FAULTS to display the Fault detail display.
Press NEXT or PREVF2 to step through the Fault list to the zone or
point to be reset.
Press RESET and OK to confirm the reset.
If the reset was successful, the state of the zone or point will change from
Fault to Normal. If the fault is still present, the fault indication will not
clear, or may clear and re-announce after a few seconds.
If the fault on a zone does not clear then the fault condition is still present
on one or more points, and these point faults will need to be cleared
before the zone fault can be reset.
For NZ systems most faults do not latch, and so clear when
the cause is removed.
When there are one or more zones, points or components that have
been disabled, the operator interface does the following:
The yellow DISABLES status indicator lights.
If fitted, the yellow zone indicator will turn on for a disabled zone.
The LCD on the interface panel indicates the presence of an Off-
Normal condition, as shown below.
