Narrative:

Takeoff from cvg to ZZZ was normal. Through 6000 ft we received approximately 6 fire fail caution messages. They went away, and then we received a left engine fire message. We did the emergency checklist and shut down the left engine. Declared an emergency and proceeded back to cvg. We set up for a landing to runway 36R. On base to final we received a right engine fire message. Informed tower and emergency vehicles of the right engine. We elected to keep it running. Upon landing we received an APU fire message. The APU automatic shut down and blew the bottle. No visual fire indications noted by emergency vehicles. Taxied back to gate with no problems. It was an indication problem due to moisture in the area of the switches. Possible drink was spilled and shorted the circuits.
