We have a job to replace some painted (4) sprinkler heads in a fire rated corridor, (I believe 2 hour). They are semi-recessed and we may have to cut a hole in the drywall to change them, the wrenches are no longer manufactured. If we cut the hole, and use one of the common 4" metal rings that fit around the escutcheon to conceal the hole is the fire rating still valid? Or should I tell the owner to call a drywall person out to drywall in the extra space?

It seems like it would make ense, but there is no listing or precedence that I am aware of for doing this or walls - unlike what is in place for glazing with window sprinklers and such. Luckily, rated doors are not that expensive. Your contractor should just buy ne.

I was hoping that there was ome code or study that allows for a water curtain to be placed on both sides of he door in order to maintain the fire rating. Has anyone heard of anything like his?
