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.
