We have put FM-200 systems for under floor coverage in a 15 - 20 thousand SF
facility and are presently discussing with a client the necessity of putting
FM-200 into a 35 000 SF facility (they presently have an 8000 SF facility
that has halon above and below the floor).

The need for FM-200 type protection should be based on the actual and
perceived risk seen by the client and any perceived benefit of minimizing
damage and downtime.

In a large facility the system should be zoned to limit the amount of gas
discharged (and associated costs).  This should be done without severely
limiting  flexibility and obstructing air flow.

Subject: DATACENTER: FM-200

And speaking of large facilites......

What's the largest facility that y'all have installed FM-200 in?
Don't name company names, just sizes.

Where's the point that you say "Hey, this facility is too big to have
FM200, use IFD/VESDA/etc"

As long as I'm asking.....does anybody know the multiplier to use to
figure out how much an FM200 system would cost, based on cubic feet?  
I've been using 1.70 - 1.85, but I want to make sure that's still valid.

Anybody bought any gas lately?  Is it still $21-23/lb???
