Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors, which pro-
vides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies of this man-
ual are available at no charge from System Sensor. (For
installations in Canada, refer to CAN4-S524, Standard for the
Installation of Fire Alarm Systems, and CEC Part 1, Sec. 32.)
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with this base must be
tested and maintained regularly following NFPA 72 require-
ments. The detector used with this base should be cleaned
at least once a year.

General Description
The plug-in detector base B401BR is used with System
Sensor 400 Series photoelectronic, ionization, and heat
detector heads. The ability to accept a variety of detector
heads makes this base more versatile than equivalent
direct-wired models. Refer to the System Sensor catalog for
other available plug-in detector bases.
This B401BR base is intended for use in 2-wire systems,
with screw terminals provided for power, ground, and
remote annunciator connections. The B401BR base also
contains a resistor to provide current limiting in the alarm
state.
