1. An electronic security system comprising:
- a power line having exactly two wires;
a power supply electrically connected to the power line and including a power supply module,the power supply module configured to receive electrical power, to selectively receive operational instructions, to modulate the electrical power with the operational instructions, and to supply the modulated electrical power through the power line;
a plurality of electronic security devices electrically connected to the power line, and configured to be powered with the modulated electrical power from the power line,each including an input/output module configured to receive the modulated electrical power, to decode the modulated electrical power to retrieve the operational instructions, to program the electronic security device based on the retrieved operational instructions, and to operate the electrical security device with the modulate electrical power and the programmed operational instructions;
wherein the power supply module also includes a multiple power supply module interface configured to couple the power supply module to and to transmit programming signals to another power supply module of another electronic security system via a line.

13. A method of establishing an electronic security system comprising the steps of:
-
receiving the electrical power at a power supply; modulating the electrical power with a plurality of operational instructions at a first power supply module of the power supply; supplying the modulated electrical power from the power supply through a two-wire bus to first and second input/output modules connected to the two-wire bus, the first and second input/output modules associated with first and second electronic security devices, respectively; retrieving the operational instructions from the modulated electrical power at the respective first and second input/output modules; operating the respective first and second electronic security devices with the electrical power from the power supply module and based on the retrieved operational instructions; connecting and communicating bi-directionally between a multiple power supply module interface of the first power supply module and a second power supply module of a second electronic security system; and mapping at least a portion of the operational instructions to a third electronic security device of the second electronic security system via the multiple power supply module interface. - View Dependent Claims (14, 15, 16, 17, 18, 20)
