I have very little circuit experience, but I can follow a schematic... my designing skills are just not developed yet. This is what I need:

I have 2 different power supplies (one actually powering the circuit (P1) and the other triggering the circuit(P2)). I also need to detect when 2 different pieces are in contact (opposite of a door alarm... when the 2 pieces are separated, the alarm goes off.)

When P2 is on... do nothing.
When P2 is off and the 2 pieces are in contact, enable a voice recording to play through a circuit speaker.
