1. A computing device for maintenance prediction for devices of a fire system, comprising:
a memory; and
a processor configured to execute executable instructions stored in the memory to:
receive fire system device data of a fire device in a fire system; and
generate a fire device analysis based on the fire system device data including:
determining a predicted behavior of the fire device by determining a maintenance index value of the fire device going into a maintenance state based on a condition code included in the fire system device data and historical device data; and
generating a predicted timeline for which the fire device enters the maintenance state by plotting the maintenance index value against a maintenance service time range for other fire devices that are of a same device type as the fire device included in a database.
