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.

Claims

1. A process of programming and actuating an access control transmitter comprising the steps of:

actuating a portable access transmitter in the vicinity of an antenna connected to a memory having at least two memory addresses and an access code associated with each memory address, wherein the portable access transmitter generates a coded signal, wherein said portable access transmitter is first actuated a multiple number of times to indicate a memory address and then actuated to transfer an access code using the coded signal generated by the portable access transmitter to said memory via a connected radio receiver;

actuating a switch;

selecting a memory address from said at least two memory addresses in said memory based upon the actuation of said switch;

transmitting a radio frequency signal modulated with said selected access code.

2. The process of claim 1, further comprising:

switching to a programming mode within said access control transmitter.

3. The process of claim 2, further comprising:

while in said programming mode, selecting said memory address indicated by said actuation of said portable transmitter from said at least two memory addresses; and

storing said access code transferred using said coded signal generated by said portable access transmitter in said selected memory address.

4. The process of claim 2, further comprising:

returning to a transmit ready mode within said access control transmitter.

5. The process of claim 1, further comprising:

selecting an output frequency for said access control transmitter.
