Disconnect for batteries

We are designing a diesel engine fire pump system. The customer has specified disconnects on the battery cables for maintenance. NFPA 20 2016 does not appear to explicitly disallow this but we believe is does introduce an additional point of failure. The customers argument is that the controller would still give us an alarm condition if the disconnect was open.


Is a disconnect allow on battery cables on a diesel engine fire pump?
