Hi! Looking for a code (NFPA72) reference that addresses multiple fire alarm control panels in the same building.  Specifically, is it even allowed?

Two separate systems, now in the same building after a wall was removed, "cross-trigger" each other.  Two locators, two FACP's, two separate indication circuits.  Is this allowed? If so, what is the code reference in NFPA72 2010
