There's a fully-sprinklered jail renovation that is using 18-foot long (13-foot wide) four-man pre-engineered steel jail cells.
Typically we would use sidewall institutional-style sprinklers which can throw up to 16-feet in length. The goal is typically to conceal the piping behind the cell so that it is inaccessible to those within the cell. Has anyone encountered these longer cells, and if so is there a solution other than putting a sidewall at the front and back of the cell? Posted anonymously by a member for discussion.

May I suggest extended coverage H.S.W if you have the pressure available. There is heads that will cover 14' x 22' requiring 31gpm @ 15 psi. (VK680). I am not familiar with institutional-style sprinklers and not sure if this head would qualify.

Typically you can come out of the chase and run your line across the top of the wall tight to the ceiling. This will allow you to position your head for the greatest coverage. Unfortunately,based on the size of the room, you may be stuck putting two heads in. After you run your pipe have the steel workers come and conceal your pip with steel. You can cut a hole in the steel for your head to stick out. Make sure the steel is bolted up and not welded to allow access for futures repairs. Naturally this will require some coordination.
