- 2-WIRE POLLING
(Zones 10
GENERAL INFORMATION
To expand the system using a P-wire polling loop
and remote point modules (RPMs), a 4171XT-XM
dialer board, and a 4152LMB loop module must be
installed, a6 described in the ZONE EXPANSION
MODULE section.
Wire each of the RPMs in parallel to the P-wire
polling loop, making sure no more than the
maximum allowable wire length is used per
individual polling loop run, a6 follows:
822 gauge @ 850’ max
#20 gauge @95v max
#18 gauge @SO0 max
#16 gauge @2400’ max
NOTE: Twisted pair recommended for all normal
wire runs.
IMPORTANT:
The maximum combined polling
loop run is 4000’. If using shielded wire, the
maximum is 2000’. If longer wire runs are needed,
a 4197 Loop Extender Module must be used.

through 64)
CAUTION
If an intercom system is being used, the polling loop
wires must be as far from the intercom wiring a6
possible (minimum 6’). If this spacing cannot be
achieved, shielded wire must be used. If this is not
done, interference on the intercom 6ystem might
occur. Also note that the maximum total wire
length supported is cut in half when shielded wire is
used.
ADVISORY
The maximum allowable current draw on the polling
loop is 64mA. Refer to the Polling Loop Current
Draw Worksheet (found in the POWERING THE
SYSTEM section of this manual) for current draws
of various polling loop devices. If more than 84mA
is being drawn, use of the 4197 provide6 another
loop with 64mA available. Refer to the instructions
provided with the 4197, or the Technical Reference
Manual for complete information.
