Model B – Open Window Nozzle

This Nozzle is designed to provide protection for exterior wall, windows and other openings of buildings that may be subjected to fire spreading from neighboring properties. It is usually installed at the top of windows or other openings. The Model B Open Window Sprinkler may be utilized in the protection of such things as horizontal, multi–tier veneer dryers and structural steel members not requiring fire–resistant insulation. For such uses the authority having jurisdiction should be consulted for the acceptance of the application. A Model B Open Window Sprinkler distributes water in a fan–shaped pattern against the exterior surface, resulting in a water curtain extending all the way to the ground.

FM-approved

Model FM – Open Cornice Nozzle

This Nozzle is installed under building cornices and ridges to provide protection for these exterior surfaces. Because of the special contour of the deflector, it distributes water equally on opposite sides in a narrow fan–shaped curtain. The distribution pattern covers the underside of cornices and ridges with water.
