Remote equipment is controlled from each of several control locations by means of an arrangement which prevents more than one control location from producing a control signal at the same time and which provides a delay between control signals for proper resetting of the controlled equipment. The response of the arrangment is optimum in that the effective delay is never greater than the minimum required for proper control of the remote equipment. The control locations may also be provided with logic circuits connected together so that each control location has the desired priority of control with respect to the other control locations.
