Narrative:

We were in cruise flight at 36;000 feet when the emergency pressure activated twice in about a 15 second time period. We declared an emergency with ATC and began a descent. A suitable airport was just off our nose and in sight; so we told ATC that we would like to divert and landed there without further issues.
