Narrative:

Approximately 30 mins to landing, flight attendant #1 was called from cockpit. I, #2, began to smell burning wire aft of cockpit door. Noticed passenger were looking around. Commuting first officer came back. We informed the #1 flight attendant and captain of the smell and went forward to investigate the forward entry area, since that's where the strong smell was coming from. I grabbed one of the halon extinguishers. Captain told crew we were going to land at ZZZ and made an announcement to passenger, but not to be alarmed to see safety vehicles approaching aircraft. Once on the ground, emergency personnel examined the aircraft and cleared us to proceed to the gate. Mechanics repaired the problem, and the aircraft was continued to ZZZ1. Callback conversation with reporter revealed the following information: the reporter stated the cause of the strong electrical burning smell was a burned up radio rack cooling fan. The captain declared an emergency and diverted the flight to ZZZ.
