A Division of Pittway
System Sensor Europe
Via Caboto 19, 34143, Trieste, Italy
Before Installing
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
manual are available at no charge from System Sensor.
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.
For use with the following smoke detectors: 1451E and 2451E

General Description
The B401R plug-in detector base is used with System Sen-
sor model 2451E photoelectronic detector head and model
1451E ionization detector head. The capability 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 plug-in detector
bases.
The B401R base is intended for use in 2-wire systems, with
screw terminals provided for power, ground, and remote
annunciator connections. The B401R base also contains a
resistor to provide current limiting in the alarm state.
