Abstract

method and apparatus to automatically store unique identity code of a plurality of wireless transmitters into permanent memory of a receiver control. By specifying and establishing in the receiver control the quantity of transmitters to be installed and causing each transmitter to transmit identity code along with a longer than normal preamble, new identity codes will be stored in receiver control memory. Each time a new identity code is stored one is subtracted from established quantity and when zero is reached storing is disabled.

Claims

1. A method for programming a receiver control permanent memory with a plurality of unique identity codes of wireless transmitters, comprising:

(a) establishing in said receiver control the quantity of said transmitters said receiver control will accept;

(b) causing said transmitters to transmit unique identity code along with a wider preamble than normally transmitted;

(c) temporarily storing each received identity code in said receiver control;

(d) comparing temporarily stored identity code to identity code stored in said receiver control permanent memory and if no match found store temporarily stored identity code to said receiver control permanent memory;

(e) subtracting one from total quantity of said transmitters specified as each said transmitter identity code is programmed into said receiver control until zero is reached;

(f) disabling storing of identity code by said receiver control when zero count is reached.

2. In a security alarm system including a plurality of wireless transmitters and a receiver control that automatically stores unique transmitter identity code into said receiver control permanent memory, comprising;

(a) means for establishing in said receiver control the quantity of said transmitters said receiver control will accept;

(b) means for causing said transmitters to transmit identity code along with a wider preamble than normally transmitted;

(c) means for receiving identity code from said transmitters and detecting a longer preamble than would normally be transmitted by said transmitters;

(d) means for temporarily storing each received identity code in said receiver control;

(e) means for comparing temporarily stored identity code to identity code stored in said receiver control permanent memory and if no match found store temporarily stored identity code into said receiver control permanent memory;

(f) means to subtract one from established quantity of said transmitters said receiver will accept and to determine if established quantity of said transmitters has reached zero;

(g) means to automatically disable storing of said transmitter identity code by said receiver control when established quantity has reached zero.
