is listed in the installation manual for each control panel. Easy
to install and maintain, this detector is designed for direct sur-
face mounting (using one of the B400 Series bases listed be-
low. Easy-to-wire screw terminals allow fast and simple field
wiring of IN, OUT, and remote annunciator connections.
Consult FireLite 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 cer-
tain 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 Auto-
matic Fire Detectors.
A MOUNTING BASE SELECTION GUIDE is included on page

JUNCTION BOX SELECTION GUIDE: Box depth is contin-
gent 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 junc-
tion 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.
GENERAL
The System Sensor 400 Series plug-in ionization smoke de-
tectors respond quickly to both fast flaming and slow smolder-
ing fires as required by UL 268. Unipolar dual chamber sen-
sor 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.
