A switch that couples transducer signal to a specific sounder of multiple sounders in response to a sensed signal from the specific sounder. The switch can include a first detection circuit that determines the sounder that is requesting the first transducer signal and a first control circuit that couples the first transducer signal to the requesting sounder. The switch can further include a second detection circuit that determines the sounder that is requesting the second transducer signal and a second control circuit that couples the second transducer signal to the requesting sounder.
