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 de-
tector 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 smoke detectors:
US Models: 1151, 1451, 2151, 2451, 2451TH, 5451
European Models: 1151E, 1451E, 2151E, 2451E, 5451E
Australian Models: 1151AUS, 1451AUS, 2151AUS, 2451AUS,4451AUS, 5451AUS
