UPRIGHT SPRINKLERS

Upright sprinklers are fire protection devices designed to discharge water upward against the deflector, creating a hemispherical spray pattern that effectively covers open areas. They are commonly installed in locations where ceiling obstructions prevent the use of pendent sprinklers.
