Lower Ceiling, Lower Sprinkler Head

[jar546]

This is a condominium, and there are other problems, other than the sprinkler head. They are using wood furring strips across the metal framing in a Type II construction for this condo. The wood will be removed as it is not allowed in a Type II.

Have to find an exception for a concealed combustible space in NFPA 13

MOre importantly, the distance from the sprinkler head deflector to the gypsum - regardless of wood or metal strips used...

It is a sidewall

1. Depending on where finished ceiling is it may be legal as is.

2. Also depends on brand/ model of sidewall. Some are allowed more than 4-6 inches down.

Issue is the other way....once sheetrock is hung, will be within an inch or so of the new lid.

All depends on the listing of the head.....NFPA 13 has a flat out no closer to a wall than 4" for a pendant head I believe, but I haven't done that many sidewall to know if there is a head that can go that close...

Think about that for a minute. For a sidewall head ... would it make sense for it to be 4” from the wall? In that case wouldn’t the adjacent surface ... the ceiling ... require the standoff distance?

Normally it is four inches down from the ceiling, for a sidewall

There are models that can be further down.

And normally the fitting is against the wall

AS a side note, the sprinkler looks like it should be replaced due to the corrosion on the finish ---- Is this area near the beach/ocean???
