Narrative:

Approximately 30 minutes after takeoff we received a level 3 forward lower cargo fire warning. Per phase one procedures 'flashing discharge switch push' was accomplished. We were 80 miles south of ZZZ. We declared an emergency with center and turned direct to ZZZ. We ran the emergency checklist for lower cargo fire. An ILS was flown to runway 36C. We cleared the runway; stopped the jet; and had crash fire rescue inspect the jet's forward exterior cargo area. They found no indication of fire. We then taxied to the ramp where crash fire rescue equipment opened and inspected the lower forward cargo compartment. No fire indications were found.
