Smoke detector would latch up.  Was an older ESL smoke. I don't
remember what revision. Owner didn't want to take a chance by just
replacing with a new unit. I replaced it with a newer unit but out side
and away from the conference room. Never tripped again, but who knows
if it was due to the move or the new unit.
