Means are provided for generating from a station a signal representative of a device address to transfer such signal to each of the devices. Means are provided for comparing the generated signal with device addresses registered in association with the devices whereby, upon identity therebetween, control of the device is effected to the generating station first to request such control. Feedback means are provided operative with the generating station and other stations to indicate the status of the device and its function, and to indicate when control thereof has been relinquished.
