My question is directed more towards members working in the fire service. But I would appreciate feedback from anyone knowagable in this area.

According to the National Fire Protection Agency (NFPA) all trunked radio systems shall have a secondary system that automaticly switches over to, when the primary fails. I was wondering if the Shawnee, Wyandotte, Sedgwick, or Johnson county system has an emergency system. If so is the secondary system a trunked or conventional system? Do the individual departments that use these systems have their own back up?

Thanks your help!
