  • a consumable partition dividing said gas generant material into first and second portions;

    a first electric-initiated igniter adjacent said first portion for igniting it in response to any signal from said sensor;

    a second electric-initiated igniter adjacent said second portion for igniting it in response to only a high-level signal from said sensor, said second igniter extending through said partition from said second portion into said first portion, whereby said second igniter may be ignited either simultaneously with said first igniter in response to said high-level signal, or sequentially, with respect to said first igniter, by the heat of combustion from said first portion.
