I have a question about how sound module interfaces with DCS. What I want to do is have various electrical actuators fire/turn on when sound module sends a signal to the other transducers/shakers/jetseat. One example is when the ejection seat fires, I want an electromagnetic lock to actuate. Essentially, when the locks magnet is electrified, it throws the bolt away from the magnet. The energy is good enough that the feeling is similar to being kicked in the back, just like being ejected from a plane. It also would be perfect for the catapult launch. So the signal from SSA would go to the seat and Sound Module normally and would still do what it does for the shakers. Nothing would change, but the initial signal going to the shaker would also provide the signal to a relay that would then open to signal the relay to open and then to fire the lock bolt.
I am not explaining it too well. The signal doesn't have to sustain anything and I don't think it would take anything away from the proper functioning of the shaker. It would essentially be like a lighted switch. The light on the switch is really just a parasitic effect and it's energy would be enough to open the relay. After the relay opens, there is no further need for electricity.
Since the signals from DCS to the Jetseat and Sound module originate in SSA, I think the answer lies here..
