Smoke Detectors - Honeywell Ademco Vista-12D Installation And Setup Manual

Installation and Setup Guide

Smoke Detectors

2-Wire Smoke Detectors
1. Connect up to sixteen 2-wire smoke detectors across
zone 1 terminals 8 (+) and 9 (-) as shown in the
Summary of Connections diagram. Observe proper
polarity when connecting the detectors.
2. Connect an EOL resistor across the loop wires at the
last detector.
4-Wire Smoke Detectors
3. Connect 4-wire smoke detectors (up to 16, depending
on detector current drain) to any zone from 2-8 as
shown on the next page. This control does not
automatically reset power to 4-wire smoke detector
zones, so you must use a relay (e.g., 4204, 4229), or
on-board trigger 17 to reset power (also required for
fire verification). Do this by programming the
designated relay/trigger as zone type 54 (fire zone
reset); see On-Board Trigger section for other
information.

Notes
• • • • Fire Verification (zone type 16):
The control panel will "verify" a fire
alarm by resetting the smoke
detectors after the first alarm trigger,
and then waiting 90 seconds for a
second alarm trigger. If the smoke
detector does not trigger again, the
control will disregard the first trigger,
and no alarm signal will occur. This
feature eliminates false alarms from
smoke detectors due to electrical or
physical transients.
• The zone 1 alarm current supports
only one smoke detector in the
alarmed state.
• Do not use 4-wire smoke detectors on
zone 1.
• Maximum current for trigger 17
output for 4-wire smoke detectors is
100mA.
