[foxboro] What causes System Alarms and What doesn't??

Hello All

We were recently surprised to discover that upon a fault of a single CP in a
fault-tolerant pair that our 6.1.2 IA System did not annunciate the problem
and only the System button in Foxview started blinking green (as if an alarm
had reset).  I'm amazed that cable faults annunciate but the fault of a
FT-CP pair doesn't.

I'd appreciate some discussion on what other hardware failures do not
annunciate and/or just blink, together with how you handle system alarms.
I'm now aware that Foxboro has a solution to turn the binking green to
blinking red for this situation.  What else will surprise us?

It appears that Foxboro has no plans to provide an upgrade for the SMDH or
the ICC - these are just available on new systems.  I wonder why they can't
provide an upgrade.

Thank you,
