2-Wire and 4-Wire
GENERAL
The System Sensor 400 Series plug-in ionization smoke detectors respond quickly to both fast flaming and slow smoldering fires as required by UL 268. Unipolar dual chamber sensor has the sensitivity needed to quickly detect smoke, and
the stability needed to avoid false alarms.
FEATURES
Unique dual unipolar sensor:
Provides exceptional stability.
Factory preset at 1.9% nominal sensitivity.
Stable operation up to 1,200 feet per minute (6 meters
per second) air velocities.
Removable cover for field cleaning.
Two visible LEDs blink in standby.
Sealed against dirt, insects, and back pressure.
Three-year limited warranty.
Field metering of detector sensitivity.
Built-in test switch.
Low standby current.
Built-in tamper-resistant feature.
Designed for direct surface or electrical box mounting.
360° field viewing angle of the visual alarm LEDs.
Insect-resistant screening (0.020"/0.508 mm openings).
Easy plug-in of the head to base.
SEMS screws for easy wiring.
Optional recess mounting.
Field-adjustable sensitivity.
APPLICATIONS
Use to contribute to life safety, fire protection, and property
conservation. Superior to photoelectric detectors in detecting
fast-flaming fires. Superior to bipolar detectors in avoiding
false alarms.
CONSTRUCTION & OPERATION
All 400 Series plug-in ionization smoke detectors contain 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. Additional
key features include a blinking LED standby status indicator,
an easily visible alarm indication, and provision for convenient
field test and metering.
The back of the detector is sealed to block back-pressure air
flow. The chamber is protected by a fine mesh (0.020"/0.508
mm) screen to minimize problems with dust, dirt, and insects.
If cleaning is required, it is easy to remove the cover (with a
special tool) and obtain access to the screen and chamber to
perform a thorough cleaning.

is listed in the installation manual for each control panel. Easy
to install and maintain, this detector is designed for direct surface mounting (using one of the B400 Series bases listed below. Easy-to-wire screw terminals allow fast and simple field
wiring of IN, OUT, and remote annunciator connections.
Consult FireLite control panel specifications for the maximum
allowable loop resistance for the particular control panel to be
used.
To prevent wiring mistakes, observe polarities and make certain that each conductor is identifiable. A copy of Installation
and Maintenance Instructions is packaged with each detector.
For further information, refer to NFPA 72 Standard on Automatic Fire Detectors.
A MOUNTING BASE SELECTION GUIDE is included on page
2 of this document.
JUNCTION BOX SELECTION GUIDE: Box depth is contingent on base and wire size. Refer to National Electrical Code
or local applicable codes for appropriate recommendations.
Bases B401 and B401B can utilize a single-gang, 3-1/2" (88.9
mm) octagonal, 4" (101.6 mm) octagonal, or 4" square junction box. Bases B402B and B406B can utilize a single-gang,
3-1/2" octagonal, 4" octagonal, 4" square, 50 mm, 60 mm, or
75 mm junction box. Base B404B can utilize a 4" octagonal
or 4" square junction box.
