Abstract
The invention provides in combination, an electronic article surveillance system for disposition in an area to be subjected to such surveillance and control circuitry connected with the system, the system generating a readiness signal when prepared to effect electronic article surveillance and being thereafter responsive to an input signal to commence electronic article surveillance, the control circuitry being responsive to the readiness signal selectively to generate the input signal and being adapted to suppress generation of the input signal responsively to further input to the control circuitry indicative of the existence of a predetermined condition. The predetermined condition is the presence in the area of a further electronic surveillance system which has not generated its readiness signal, and the invention looks to interconnecting the further system to the control circuitry.
