VISTA-50P/VISTA-50PUL Installation and Setup Guide
Step
Action
Wire each device to the polling loop, making
5
sure of the correct polarity (refer to the
device's instructions).
NOTE: If you are using serial number
devices, and intend to enroll each device
through the keypad automatically, wire no
more than 25 of these devices to the
control at a time. Then power up and
program them before connecting the next 25.
Leave previously enrolled devices connected.
If you intend to manually enter the serial
numbers through the keypad or through
Compass downloading software, all the
devices may be connected before powering
up to program.

Polling Loop Supervision
A short on the polling loop is indicated by a trouble on
zone 97 and reports as a trouble condition only. If
annunciation is desired, program the zone as type 05.
If a device on the polling loop fails (the panel cannot
"see" that device), the system displays a trouble
condition for all zones on that device. If the panel is
armed when a device fails, and the zone is a burglary
zone, the will go into alarm
A trouble on zone 97 prevents a partition from
being armed, unless all polling loop zones on
that partition are bypassed.
Using the 4297 Polling Loop Extender
The 4297 Polling Loop Extender may be used to provide
additional polling loop current, to extend the polling
loop wire run length, and/or to provide individual
electrically isolated polling loops. Refer to Figures 3-17
and 3-18, to follow.
DO NOT use the 4197 Polling Loop Extender
module with the VISTA-50P/VISTA-50PUL.
Be sure to include the total current drawn on
the polling loop when figuring the total auxiliary
load on the panel's power supply.
