Basic Wired Zones - Honeywell Ademco Vista-12D Installation And Setup Manual

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 signalling on the same 2 wires used for alarm
signalling, 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).

Mounting and Wiring the Control
Notes
• 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.
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:
Zone Paired with zone

3 11
4 12
5 13
6 14
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).
