How to program a Honeywell Ademco Vista 20p output trigger to control a garage door.

NOTE: As some have mentioned, a complete lose of power to the system (AC and DC battery fail) will cause a pulse to the trigger contacts on power up which may cause the relay to trip. This could in turn cause your garage to open. Some guys found a work around for this with additional equipment. I have multiple battery backups and a generator so not an issue in my install. Work on your system at your own risk.
