Learn mode transmitter

Claim 3

A method as set forth in claim 1 wherein said predetermined transmission comprises a tamper alarm condition at a transmitter enclosure.

Claim 4

A method as set forth in claim 1 including the step of defining an index value corresponding to each stored identity code and its location in the code table.

Claim 5

A method as set forth in claim 1 wherein each of said plurality of wireless transmitters is constructed to include an electrically programmable read only memory, and including the further step of permanently programming a portion of said read only memory of each transmitter with a pseudo-random identity code as each transmitter is manufactured.

Claim 6

A method as set forth in claim 4 wherein said permanent programming comprises the steps of: (a) coupling the output of an identity counter to a data input of said wireless transmitter; (b) establishing each transmitter in a program mode; and (c) writing the output of said identity counter into the identity code table of said wireless transmitter.

Claim 7

A method as set forth in claim 5 including the further steps of: (a) partitioning said identity counter output into a plurality of data groups; (b) individually writing each of the plurality of data groups; and (c) clocking a group counter as each data group is written and terminating said program mode at a predetermined group counter count value.

Claim 8

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.

Claim 9

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.

Claim 10

Apparatus as set forth in claim 7 including means for establishing an unique index value for each identity code stored in said table.

Claim 11

Apparatus as set forth in claim 7 wherein during an armed mode said system controller compares each temporarily stored identity code to said identity code table and responds only if a correspondence is detected.
