FM200 multiple area of protection
FM200 multiple area of protection
(OP)
Dear All,
I would like to ask if I could use only one FM200 container to protect multiple rooms? The size of container will be selected based on largest area protected.
But what if the smallest area has fire? Do all the agent in the container discharge?
Thanks!

Thank you for the response. So assuming the room is closed and there is no way gas could escape, the discharge will stop after the required time is reached?

Once the system dumps there is no stopping it, the entire cylinder will discharge

So...if one room takes 400 lbs of agent, and the other room(s) take 200 lbs, use two (2) cylinders with each cylinder filled to 200 lbs.
You'll likely have other issues however. Just because the math works, doesn't mean the hydraulics' will work. Selector valves impose a significant equivalent length in the piping system.
There are two (2) manufactures (in the USA) that have systems with sufficiently high enough pressure to overcome the equivalent lengths of the selector valves. They are:
Kidde with their "ADS" (Advanced Delivery System).
Minimax with their high pressure systems (720 PSI).
If you're specifying a system, I would suggest you contact a company that can run the calc's and verify that it's possible "Hydraulically". At some point the costs can become prohibitive.
Regards,
DM
