Product Overview
12 or 24 volt operation
Removable cover and insect screen for
easy cleaning
Visible LED blinks in standby, latches on
in alarm
All 400 Series ionization smoke detectors include a unique dual source, dual unipolar
chamber detection design which will sense the presence of smoke particles produced by
fast combustion as well as slow smoldering fires. This chamber exhibits increased stability,
significantly reduces nuisance alarms, and provides better performance at higher air
velocities.
Dual unipolar chamber design
The 400 Series meets the performance criteria required by UL/ULC. Additional key
features include an LED which blinks in standby and latches on to indicate an alarm.
Detectors feature convenient field testing and sensitivity metering. The model 1400
includes remote LED annunciator capabilities using the RA400Z.

Smoke detector shall be an ionization type (model 1400, 1412B, or 1424) as manufactured
by System Sensor. Wiring connections shall be made by means of SEMS screws. Detector
will have a visible LED which will blink in standby and latch on in alarm. The detector
shall have a sensitivity of 1.9 ± 0.6%/ft. as measured in the UL smoke box. The detector
screen and cover should be easily removable for cleaning. It shall be possible to perform a
sensitivity and functional test on the detector without the need of generating smoke. The
detector shall have a mounting bracket that allows for mounting to a 3 1/2 ″ or 4″ octagon
box or 4″ square electrical box.
