Make certain to include the total current drain on the polling loop when figuring the
total auxiliary load on the panel's power supply (use the AUXILIARY CURRENT
DRAIN WORKSHEET in the FINAL POWER UP PROCEDURE section.

Loop
VISTA-120
An overload on the polling loop is indicated by a trouble on its supervisory zone
(997) and reports as a trouble condition only, even if the system is armed. As
such, it should be assigned zone type 05 if annunciation is desired.
If a device on the polling loop fails (the panel cannot "see" that device), the
partition (or partitions) that use that device will display a trouble condition for
all zones associated with that device. If the panel is armed when a device fails,
the zones associated with that device will cause an alarm on the corresponding
partition(s).
A trouble on Zone 997 will not prevent a partition from being armed, as long as all
polling loop zones on that partition are bypassed.
