hi - frank will presumably respond as well, but my vote would
be to set *no alarms whatsoever* on TOFp's HVSys.
that system has always been a little schizo - we know this.
there is definitely not a need to bother the shift crew w/
this noise.
an alarm on the tofr gas mixture is really the only
one that is really necessary i think....
re: your comment on accessing the data, that's not necessarily
a huge need - we can access it "directly" too. but a web-based
path to that archived data would be a nice feature....
thanks,
bill
