Smoke Detectors
4-Wire Smoke Detectors
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.
•
Maximum current for trigger 17 output for 4-
wire smoke detectors is 300mA.
