Gengtlemen: There is no restriction in NFPA 13 on using 175 degree sprinklers. In some cases it is better to use 175 degree sprinklers i.e. A residence that might not be air condition in the hot summer months. Or if the engineer, owner or developer just wanted to use 175 degree sprinklers. Note: Some sprinklers are not available in higher temperatures. Michael L. Brown

If not, then you should use the temperature ratings as described in NFPA 13. What advantage would there be to using 175 degree sprinklers only? There shouldn't be any problem mixing temperature ratings as long as they are detailed on the drawing as to what to use where. Todd G.
