General Description

The model B116LP plug-in detector base is used with

System Sensor model 1151, 1151A, and 1151E ionization

detector heads and model 2151, 2151A, and 2151E photo-

electronic 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.
