3-1
Fault conditions are used to indicate something wrong, e.g. the presence of a field wiring
problem (circuit break, short or ground), somewhere between the 4100U-S1 and one of its
points. Faults are also used to indicate a problem with the 4100U-S1’s option cards, power
supplies, network card, etc.
Note that disabling a point introduces a fault condition into the system.
Isolate conditions exist when one or more zones have been manually isolated by an operator,
e.g. to prevent a false alarm when maintenance work (e.g. building repairs, welding) is being
done in an area.
This chapter describes using the operator interface keys to investigate the details of the fault
condition, and to view isolate conditions.
