Intelligent Detector Bases Wiring an Isolator Base
9.3 Wiring an Isolator Base
The Isolator Base will isolate its detector from short circuits that occur on the SLC connected at
terminals 3 and 2. It will not isolate its installed detector from short circuits that occur on the SLC
connected at terminals 1 and 2. In Style 7 applications, the loss of a single detector during a short
circuit is not acceptable, and an isolator module must be installed as shown in the figure below.
