There was a comment that SS sprinklers were used to protect "Small" openings. Some of those small openings such as the windows in doors are OK by code up to a specific size, openings larger than that size would require listed protection in a listed assembly.

Only listed window sprinklers are tested and listed to provide an actual fire resistance rating for glazing. This is because these sprinklers are tested in accordance with the ASTM E119 standard for fire resistance. If the glazing is located in a fire rated assembly, like a rated corridor wall, the fire resistance must be maintained for the opening protective. Therefore, if sprinklers were to be used for this purpose in lieu of fire rated glazing, the listed window sprinklers must be used. In addition to the testing for the fire rating, the positioning of the sprinklers relative to the glazing is also test specific, as this ensures all areas of the are wetted. This does not apply to regular spray sprinklers. Regards, Salvatore J. Izzo, P.E.
