I have an armover that is 2'-4" in length. The SEOR is requiring me to put a diagonal brace on the branch line that the armover is supplied from and a restraint on the armover ( I had left a branchline restraint detail from my template and I probably should not have left it on with these small aromovers) When is an armover required to be restrained (if at all?). Could not find any specific length in NFPA-13 (2016 ed.)
