Learn mode transmitter
First Claim
1. A method for programming a local security system controller with the identity of each of a plurality of wireless transmitters to whose transmissions it is to respond, comprising:
- (a) programming a unique identity code into each of said wireless transmitters which identity code is transmitted with each transmission;
(b) establishing said system controller in a program mode;
(c) inducing a predetermined transmission from one of said wireless transmitters;
(d) temporarily storing each received identity code as it is received by said system'"'"' controller;
(e) upon detecting said program mode and a predetermined alarm condition, comparing each received identity code at said system controller to a code table; and
(f) writing the temporarily stored identity code into said code table, if not located.

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.

7. In a security alarm system having a system controller and a plurality of wireless transmitters operative to transmit at radio frequencies a plurality of conditions, apparatus for identifying to said system controller to which received transmissions it is to respond, comprising:
-
(a) means for permanently storing a unique identity code in each of said plurality of transmitters which is transmitted with each transmitter transmission; (b) means for temporarily storing each received identity code at said system controller; (c) means for operating said system controller in a program mode and an armed mode; (d) means at said system controller for detecting the condition inducing each received transmission; and (e) means at said system controller for comparing a received identity code to a table of codes, upon detecting a program mode and a predetermined one of said plurality of detectable conditions, and writing said temporarily stored identity code into said table if not already present. - View Dependent Claims (8, 9)
