What I have done in the past for a room or a prop is this: I first record my audio onto my audio repeater. I then program my Animation Maestro to control my pnuematic prop (solenoid valve) and have it do what I want it to do in sync with the audio. Finally I set my timer (you could also use an Animation Maestro to control lighting as well), to turn on and then turn off my lighting. There's 3 seperate components that need to be switched at the same time. You now pick up a 3 pole 24volt relay, hook the three components to it. And at last, pick up a 24voly transformer and a doorbell switch. Wire that up to the 24v relay. Now with the push of one button, all 3 components: animation, lighting, and audio are activated at the same time.
