Multiple Dry/Pre-Action Systems on Compressor?

1/14/2019

Can multiple sprinkler systems be connected to a single air compressor/nitrogen generator?

NFPA 13 states that the 30-minute fill time would be based on the single largest system; so I'm assuming it's permitted and under this arrangement an air maintenance device would be needed to maintain the pressure in each system.

Yes. It's permitted and I have done it. It's also permitted with plant air, for which often times there is one compressor for multiple sprinkler systems as well as the plant.
