General Description

The B401B plug-in detector base is used with System

Sensor model 2451 and 2451TH photoelectronic detector

heads and model 1451A ionization detector heads. The

capability of plugging these detectors into a variety of spe-

cial bases makes them more versatile than equivalent

direct-wired models. Refer to the System Sensor catalog for

other available plug-in detector bases.

This base is intended for use in 2-wire systems, with screw

terminals provided for power, ground, and remote annun-

ciator connections.
