Sorting
Annunciator items are sorted first by their category
assignment. The category order is:
LCI, ILK, PII, Other (Unused items appearing in the Other
category)
Within the category, inputs are sorted by the input identifier
(A1–A8), with the additional rule that LCI (if enabled) is last in
the LCI category, ILK last in the ILK category, and PII (if
enabled) is last in the PII category.
Viewing the System Display using the "programmable"
annunciator display in this case would resemble Fig. 27.

If A7 is defined as a HFS input, then the parameter that calls it
a "Security door" would be ignored and the automatic value
(High Fire Switch) is used instead (the same would be true for
the A8 LFS and A1 IAS).
