  • an elongate ignition cord;

    an initial gas generant, initially surrounding the ignition cord; and

    an initiator;

    a housing having upstream and downstream ends and an interior space and wherein the initiator is mounted in the upstream housing end; and

    a sustainer gas generant;

    wherein;

    the initiator is positioned to, upon triggering, cause ignition of the gas generant so that the gas generant combusts over a first time interval so as to generate gas in a sufficient amount to substantially extinguish a fire; and

    the initiator is positioned to, upon triggering, cause ignition of the sustainer gas generant so that the sustainer gas generant combusts over a second time interval, ending after an end of the first time interval, so as to generate sustainer gas in a sufficient amount to substantially prevent reignition of the fire.
