In traditional architectural terms a lintel is the piece between two vertical supports over a portal, so it could (and often is) used to describe the header span not only over doors but also windows.

If a beam would suffice, a room with a beam is would be two compartments. We reasonable assume that a fuel package is not placed within a doorway (aka under the lintel).

Isn't the intent to basically have a compartment capable of containing the heat in one area and ensuring only the sprinklers in the compartment operate? In dealing w/ compartments it is acceptable to have openings into other areas as long as the minimum lintel depth is met. This beam is basically an 18" lintel separating the two areas. > > > _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler .org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
