Can sidewall heads be used for water curtain application?
While typically pendent are used to provide a water curtain around a vertical opening, I am working on a project where the arrangement led to sidewall heads being preferred by the architect.
NFPA 13 is not explicit about water curtain needing to be a specific type of sprinkler, it just says it should be a standard spray with 3gpm /lineal ft applied.
Thanks in advance.
