FM200 duct dampers for sealed enclosure

FM200 duct dampers for sealed enclosure

FM200 duct dampers for sealed enclosure

(OP)
Hello everyone!
Several type of ducts are passing in the ceiling of a room protected by FM200 system as follow:

1-Supply duct to the space
2-Return duct to the space
3-Fresh air duct to the space
4-Exhaust air duct to the space
5-A series of ducts that are crossing the protected room walls to serve other areas (without having a supply or return grill inside the protected room with the FM200)

-The motorized damper should be installed at the duct when penetrating the protected room for all the duct mentioned above (point 1/2/3/4/5) or it must only be installed for point (1/2/3/4)?
-As well the motorized damper must be a motorized smoke fire damper? or can be a normal motorized damper?

I already try to search in the NFPA 2001, but i was not able to find a reply.
Thank you very much for your help :) :) :)

RE: FM200 duct dampers for sealed enclosure

the walls are not fire rated for some spaces
