Duct under sprinkler
Duct under sprinkler
(OP)
Is it possible to put an pendent under and off to the side of a large duct? I would be putting an upright at a higher elevation, dropping the deflector of the pendent just below the bottom of the duct and providing a water shield.
I've done similar things in the past without issues but I'm not sure if the lower head will actually be set off properly if not placed directly under the duct. See attached for my two thoughts

AND, I try very hard not to approve pie plates attached to the head.
Heard one theory that the hot gases will possibly go around the pie plate.
Head should be under duct.

Like I said I do not like them and try very hard not to approve them, though it seems I have not seen them proposed in a long time.
