Sidewall Sprinkler Head with Pendant Sprinkler in Coverage Area

Question asked by dan callahan on Oct 6, 2017

Hi all,

I am trying to install a sidewall sprinkler head with a coverage area of 14' x 14'. The room has a pendant sprinkler that is less than 6' away from where the sidewall sprinkler would be located. NFPA 13 code 8.7.3.1.6 states that there cannot be adjacent or opposite sidewall heads in the same room and 8.7.3.4 states that sidewall heads cannot be less than 6 feet apart. If the other head in the room (pendant head) is within 6 feet and adjacent to the sidewall head, is this allowed? The pendant head would be approximately 3" below the ceiling and the sidewall is 6 inches below.

Reference NFPA 13 Codes:
8.7.2.2.1
8.7.2.2.2
8.7.3.4
8.7.3.1.6
