ABSTRACT:
A method and apparatus in a security system whereby a central processing unit self learns the identities of its distributed wireless keypad and alarm transmitters. Each transmitter includes an electrically eraseable memory containing signal conditioning data and a pseudo randomly programmed identification code. During a transmitter initiating programming condition, the CPU captures the received identification code of each transmitter and establishes an identity code table by which subsequently received transmissions are confirmed as belonging to the system.
