F and K input Supervision
Although the F and K inputs will work when they are unsupervised, as shown in Figure 5-21
on page 5-25 and Figure 5-22 on page 5-26 , Software House recommends that you use the
standard Software House method of supervising the inputs. Use parallel/serial for the
normally open K input and use serial/parallel for the normally open F signal.
The wiring is shown in Figure 5-23 on page 5-26 . Be sure that the resistors are as close as
possible to the F and K switches for the most security.
