Narrative:

Flight pushed back and began a taxi to runway. We started the left engine first then did a delayed start on the right engine. Prior to the end of the runway; all checklists were completed and the cabin was ready for takeoff. The captain was the PF and I was the pilot monitoring. Tower cleared us for takeoff and assigned us a 250 degree heading with a climb to 10000 ft MSL. The takeoff and initial climb were normal. Tower told us to switch to departure. The after takeoff checklist was completed. Departure control assigned us a turn left to a heading of 190 degrees. Once established on the 190 degree heading and climbing through approximately 8500 ft MSL; the engine fire warning for the left engine came on. The captain and I performed the memory items. The duties were then split. The captain continued to fly and took responsibility for ATC communications. I ran the QRH procedures and communicated with the cabin crew; passenger; and flight control. After we closed the left thrust lever; the left engine no longer indicated a fire. I asked the lead flight attendant to discretely look at the left engine for any signs of an abnormal condition. When she reported back she said everything appeared normal; however; one of the flight attendants reported a smoke odor. With this information; the captain and I decided to continue with the QRH procedure that guides us to shut down the engine. Once shutdown with the fire handle pulled; there were no other indications of a fire. An emergency was declared with a return to land. We were vectored for an approach to runway . The descent and approach checklist were completed. The approach and landing were uneventful. The aircraft was stopped on taxiway M. The fire personnel completed an exterior inspection. They reported no evidence of an engine fire. We then proceeded to the gate and shut down.
