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 2-6 as
shown below. 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.
