Wiring an Isolator Base

9.4 Wiring an Isolator Base
The B224BI Isolator Base will isolate its detector from short circuits that occur on the SLC con-
nected at terminals 2 and 3. 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.
Note: The "grid" pattern on the
redesigned B224BI mounting
plate has been removed for
illustration purposes only.

9.5 Wiring a Relay Base

Figure 9.3 shows typical wiring of a B224RB plug-in relay detector base connected to an SLC.
