WI853C XP-400 Installation Instructions
,QVWDOODWLRQ
Mounting the Panel
Mount the Panel close to an unswitched AC
source, a cold-water pipe ground, and a tele-
phone line connection.
Mounting the Keypad
A keypad should be located near an exit/entry
door. To remove the keypad from the backplate,
insert a small screwdriver into the slots at the
bottom of the keypad. Pull up on the screwdriver
to pop off the cover.
Up to 3 keypads can be connected on individual
wire runs with #22 AWG wire with a maximum
total cable length of 1000 feet. Each keypad
draws approximately 35 mA.

Grounding the Panel
Connect the control-panel EARTH GROUND
screw to a metal cold-water pipe. Do
not
use a
gas pipe, plastic pipe or AC ground connec-
tions. Use at least #16 AWG wire. Connect a
wire with a ground lug crimped or soldered onto
one end and connect it to the EARTH
GROUND screw in the cabinet.
AC Power and Battery Wiring
Complete all wiring before connecting the bat-
tery or AC Power. Do
not
plug the transformer
into a switched outlet.
Telephone Wiring
Wire as shown in the wiring diagram in the back
of this manual.
WARNING
The FCC restricts the use of this equipment on
certain telephone lines. Read the FCC state-
ment on the back of this manual to ensure
compliance.
Burglary Zone Wiring
NAPCO’s EZ Zone Doubling
TM
is simple. Each
terminal has 2 zones, use an E (2.2 K) type
Zone Doubling Resistor for the primary zone and
a Z (3.9 K) type Zone Doubling Resistor for the
secondary zone.
Wire zones as shown in the wiring diagram (pg.
27). All resistors must be installed, even if the
zone is not used. If required, unsupervised
open
circuit devices may be used instead of closed
circuit devices. Program the zone as an
Open
Circuit Zone [06] (Zone Doubling Resistor re-
quired). If necessary, use the voltage chart
below to verify proper voltages.
