1. A remote control adaptor for use with an electrical firing control signal generating detonator for controlling the actuation of a self-powered device comprising:

  • input terminal means for receiving an electrical firing control signal from a detonator;

    output terminal means for connection to a self-powered device to be actuated;

    switch means connected between said input terminal means and said output terminal means and being selectively operable to produce open-circuit and closed-circuit states at said output terminal means;

    said switch means being operable in responsive to an electrical firing control signal applied to said input terminal means to produce a closed-circuit state at said output terminal means to thereby actuate a self-powered device connected thereacross; and

    indicator means connected to said switch means for generating a warning signal indicative of a closed-circuit state at said output terminal means prior to the connection of the self-powered device to the output terminal means as an indication of an unsafe connection condition.
