NFPA 13 (2019) Section 22.214.171.124 states that quick-response sprinklers shall not be mixed with any standard-response within a compartment unless some conditions apply.
126.96.36.199 Where quick-response sprinklers are installed, all sprinklers within a compartment shall be quick-response unless otherwise permitted in 188.8.131.52, 184.108.40.206, or 220.127.116.11.
Those conditions don't apply in my case and I know there's a definition of a compartment in 3.3.38.
However, from a practical standpoint if the compartment in question is a corridor, would you include the adjoining offices in the compartment? These offices are likely to have their doors open and are not on any magnetic door closing devices.
