General Description
This B401 plug-in detector base is used with System Sensor
smoke and heat detector heads. 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 available plug-in
detector bases.

The B401 base is intended for use in 2-wire systems, with
screw terminals provided for power and remote annuncia-
tor connections.

For use with the following detectors:
US Models:

1151, 1451, 2151, 2451, 2451TH, 5451

European Models:
