First Alert FA2000C Installation And Setup Manual page 19

Wiring 2-Wire Smoke Detectors to Zone 5
Connect up to 16 of the 2-wire smoke detectors listed below across zone 5 terminals 15 (+) and 16 (–).
Observe proper polarity when connecting the detectors. Connect the EOL resistor at the last detector.
Due to the alarm current available on zone 5, only one smoke detector at a time can be supported in the alarmed
state.

This model may not be used on zones designated as Zone Type 16: Fire with Verification.
•
These smoke detectors are UL Listed for use with the FA2000C, and are the only 2-wire smoke detectors that
U L
may be used.
•
A combination of heat detectors and smoke detectors is not permitted on a zone programmed for fire verification.
•
UL Fire installations require the use of a synchronization module to synchronize the sounders and strobes on the
system.
Fire Alarm Verification for Smoke Detectors
This feature applies to 2-wire smoke detectors wired to zone 5 when zone 5 is set to response type 16. This feature also
applies to 4-wire smoke detectors wired to any zone when the zone is set to response type 16 and the detectors are
powered from the Aux relay power output (field 34 must be set to 2).
The control will verify any 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 due to electrical or physical transients.
