ABSTRACT:
An electronic security system which includes an infrared (IR) transmitter operable to broadcast a digital identification code signal at a pre-selectable programmable baud rate. Also included is an IR receiver responsive to the identification code signal received at the programmed baud rate. Further included is a comparator within the receiver to compare the received IR signal and its baud rate with baseline references. The comparator is operably coupled with an ignition circuit when the pre-selected code and baud rate matches the received digital code and baud rate. Both said transmitter and receiver are held within enclosures that are, on their external surfaces, IR transparent and visible light opaque. The internal surfaces of said enclosures are IR reflective.
