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.
