Abstract
A sprinkler system, for cooperation with an array of ceiling tiles, essentially features a mount of tiles including at least one with a central opening, a web disposed above the mount of tiles and including a central hub and legs extending therefrom to the corners of a frame with a dimensional profile like that of the tiles, a number of ceiling wires supporting the frame in spaced relation to a ceiling, a sprinkler head supported within the central hub and extending through the central opening, and apparatus for connecting the sprinkler head to a source of fluid. Preferably, the apparatus includes a rigid stationary water grid and supply and a flexible hose connecting the sprinkler head to the water grid and supply. Preferably, the flexible hose is an annealed stainless steel braid hose having an open pitch.
