Narrative:

Flight was to operate from syr to dtw. We left the gate on time and had a normal climb to FL280. While in cruise flight 30 mi west of aylmer VOR, the cargo smoke and master warning annunciator illuminated along with the warning horn. I continued to fly the airplane along with the radios. We began the divert to bus as the captain had asked. I declared an emergency with the communication section 2.26.6 (cargo smoke). The flight attendants were informed of the emergency (yellow) and the passenger were briefed. The aircraft was operated at maximum forward speed until a 5 mi final. We were cleared for the visual approach. The landing was uneventful and the aircraft was stopped quickly and turned off the runway. Crash fire rescue equipment was instructed not to open any cargo bins, but only to inspect the outside for smoke. The indicated to us that no smoke was present. We taxied to the gate, deplaned all passenger and crew before inspecting the cargo bins. No evidence of smoke, fire, or intense heat was noted.
