How can I power multiple devices simultaneously using KC868-A16?

Sure, here is how I wired two sirens for testing purposes. I am using the junction terminal block seen here as an easy way to connect each of the negative siren wires to the same ground terminal of the power supply, since otherwise they would not all fit inside that terminal. The positive wires of the sirens are in output 15 and output 16.
