Narrative:

The aircraft descended to 400 feet prior to the FAF which has crossing restriction of 1500 feet. I noticed the descent then tried to contact the aircraft on my frequency; guard frequency; and through the tower. The pilot finally contacted tower. I don't remember if I gave him his position; reference a point on the approach or not. Sometimes I'll turn aircraft onto final; then give them a position when they are closer to the fix before I switch them.I did feel a little pressured. Sectors were combined and we were on an unusual runway configuration.
