Complete the statement on the propulsion section arm and firing sequence.
The rocket motor Safe Arm Device (SAD) provides an out of line ____________ whose electrical contacts are grounded and __________ in the safe position. The CIA card provides the _______ 28 V power which rotates the rocket motor squib in line. If the SAD is returned to__________ volts the SAD will rotate back to its original (safe) position. The SAD should not be energized for more than __________ or the SAD may be damaged. Once voltage is removed from a damaged SAD it will return to a
_________ under the action of the return mechanism. A fire pulse providing more than _______ (each squib) will fire the dual (redundant) rocket motor _______ to ignite the rocket motor.
