ABSTRACT:
A method for actuating an access control transmitter in which a four code access transmitter is employed with the dimmer switch flashed once to produce a first signal, twice in rapid succession to produce a second signal, three times in rapid succession to produce a third signal, and four times in rapid succession to produce a fourth succession. Each separate signal is an access controlled signal to gain access to an access controlled area such as a garage. Programming of the access controlled transmitter occurs by actuating a standard transmitter nearby, when the access transmitter is in a programming mode. A programming access mechanism is provided to prevent authorized programming of the access transmitter by one not having the programming access code.
