Abstract:

An evironment which is protected from fire employs a nozzle arrangement having three discharge apertures for distributing a fire suppression fluid such as HALON. The environment is arranged in a predetermined area or space having an odd shape, such as an L-shape, and is adequately protected with a single nozzle arrangement. The nozzle arrangement is characterized by a chamber for receiving the fire suppression fluid at a rate of flow sufficient to supply the fire suppression fluid to the three apertures in conformance with applicable specifications, such as those established by Underwriters' Laboratories, Inc. The discharge apertures in the nozzle arrangement are in the form of through-holes arranged in the chamber wall. Preferably, the apertures are arranged at 90. degree. increments around the chamber wall, whereby the fire suppression fluid is discharged in diametrically opposed directions, and orthogonal thereto.
