Strange such an expert doesn't realize there are 8 -- not 7 -- alarm types.
Napco decided to use the 8 most common alarm signals: Fire, Panic, Holdup, Gas
Heat, Auxiliary and "24 Hour".  This is always followed by the zone ID, with
which any competent CS is able to display "Burglary: Zone 27, Left Rear
Window" or whatever else is needed.  The Napco panels can send the above 8
Alarm types plus Alarm Restore, Trouble and Trouble Restore.  As well, Napco
will report Openings, Opening  After Alarm, Closings, Conditional Closing,
Late to Open, Late to Close, Cancel codes, System Troubles of every type, A/C
and System Battery trouble and Restore, RF Battery trouble, etc.

DSC allows the panel to send different codes for every zone.  The problem with
that is the results are non-standard.  You can mistakenly program the DSC
system to send a fire alarm from a burglary zone or vice versa.  One of the
main points of Contact ID and "SIA" (technically, they're both SIA formats but
there's no need to quibble) is to standardize the signals sent for each alarm
condition.  You want to have any panel reporting a Burglary condition to send
only the codes which indicate Burglary.  The Contact ID format does allow
panels to report various sub-types, such as Burg on a Delay Zone but few
panels actually use that and, judging from what I've seen during takeovers,
most installers don't even know how the full code set.  Honeywell panels do
make use of the full code set, but it's their format so that is to be
expected.
