It's a question that comes up again and again. Roughly 4 percent of new homes all over the country are being sprinklered, a figure that is on the rise. If the basements in these homes are “finished” - complete with gypsum board or acoustical tile ceilings - then certainly the type of sprinklers to be used in conjunction with this type of construction is listed residential pendent sprinklers or, more commonly, residential pendent “concealers.”
Meanwhile, if the basement is an “unfinished” basement, then you will logically want to turn to the code for answers. The trouble is, you won't find any.
