I don't think you should buy from a person who would sell you this product without being sure they could sell you more stuff by asking if you had the power supply and door sensor worked out! You should have asked what it should be used with it. Please check online or by phone with the manufacturer before buying? I mean, what if this thing works on 115VAC 400 Hz* power?

God gave you a butt so you could sit on it and make phone calls to people who know more about this than we do!
