I'm currently the PDL. It's bad practice to tell shift
people to ignore an alarm, unless it's temporary.
I suggest that you post a message to the effect that
the alarm is not valid and should be ignored FOR NOW.
You (or Krister or Steve) should post it in multiple
places (post-it notes at various places, on white-board,
on today's banner for current run (talk to run coordinator)),
etc. Please indicate that it's temporary, also date the
notes and sign them.
Tell me if this is ok, and when it's been done.
