Narrative:

After landing runway 34R, ZZZ ground instructed us to taxi to the ramp. While taxiing and performing after landing checklist, the fire bell rang and the #1 engine fire handle was illuminated. The bell was silenced and the captain called for the engine fire checklist. Ground control was notified and the emergency equipment was requested. The fire warning continued after the engine was shut down. We shot the #1 fire bottle and the fire warning extinguished. We asked ATC if there was any indication of a fire. They said no. The fire warning bell and #1 engine fire handle again indicated fire. We fired the second extinguisher bottle. All warnings again extinguished. We asked the flight attendants if there was any indication of fire on the outside of the aircraft. They said 'no,' but also said they heard a 'pop' earlier. By now the fire procedure was complete, the fire trucks had been around the aircraft a couple of times with no evidence of a fire. We elected to taxi to the gate and deplane, with rescue equipment following. During the taxi, the fire bell and indicator went off again, but intermittently. We concluded it was a faulty detection system. We deplaned normally at the gate.
