Image Description - 0766-1 A block diagram is captioned "Figure 1. SRB Command Destruct System Functional Diagram". Commands are received by command antennas and processed to the Integrated Receiver Decoder of Side B. The signal is sent to the Side-B Distributor Subsystem. Side A and B distributor subsystems have the capability for cross strapping. The fire command is sent to the NASA Standard Detonators and passes through the Safe and Arm Device and the confined Detonating manifold. This in turn activates the destruct assembly, which contains the Linear Shaped Charge.
