Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors, which
provides detailed information on detector spacing, place-
ment, zoning, wiring, and special applications. Copies of
this manual 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 B401BR750 plug-in detector base is used with System
Sensor model 2451 and 2451TH photoelectronic detector
heads and model 1451A ionization detector heads. The ca-
pability of plugging these detectors into a variety of special
bases makes them more versatile than equivalent direct-
wired models. Refer to the System Sensor catalog for other
available plug-in detector bases.
This base is intended for use in 2-wire systems, with screw
terminals provided for power, ground, and remote annun-
ciator connections. It also contains a resistor to provide
current limiting in the alarm state.
