Seismic Restraint/Bracing for 1-1/2" CPVC Main?

I am designing a fire suppression system for a residential building in a seismic area (BC, Canada). There is 1-1/2" CPVC pipe running down the corridor with 1" branches going into each suite. I'm using NFPA-13 (2013).

Does the 1-1/2" pipe in the corridor count as a cross-main, and thus require seismic restraint, or can it be omitted given its small size?

If it does require restraint, would a Tolco 3000 clamp, 909 brace fitting, and 1" shed 10 steel pipe be acceptable?

What sort of solutions are typically used for small CPVC pipe?
