Installation and Setup Guide

Basic Wired Zones

Normally Open Zones/Normally Open EOLR
Zones
1. Connect open circuit devices in parallel across
the loop; for EOLR zones, connect the EOLR
across the loop wires at the last device.
2. Enable normally open/EOLR zones using
Zone Programming mode, "Hardwire Type"
prompt.
Normally Closed Zones/Normally Closed EOLR
Zones
1. Connect closed circuit devices in series in the
high (+) side of the loop; for EOLR zones,
connect the EOLR in series following the last
device.
2. Enable normally closed/EOLR zones using
Zone Programming mode, "Hardwire Type"
prompt..
Double-Balanced: Connections as shown
(resistors provided for one device in selected
models); maximum of 8 sensors on each double-
balanced zone.
IMPORTANT: Double-balanced zones provide
unique tamper signaling on the same 2 wires used
for alarm signaling, and should be used as
burglary or emergency zones only. Do not use
double-balanced zones as fire zones.
Zone Doubling: Connections as shown (resistors
provided).

Zone Doubling:
This feature provides two unique zone
identifications for normally closed sensors
connected to each basic wired zone (but does not
increase the total number of zones supported by
the control). Do not use zone doubling for fire
zones. If enabled (Zone Programming mode,
"Hardwire Type" prompt, option "3"), basic
wired zones are automatically paired as follows:
NOTE: A short across the EOL (i.e., at
terminal) on either zone of a zone-doubled pair
or on a double-balanced zone causes a tamper
condition (displayed at keypad as CHECK).

EOLR: If the EOLR is not at the end of the
loop, the zone is not properly supervised and
the system may not respond to an "open" on
the zone.
Zone 1 is intended only for EOLR usage.
