Can I add any sirens in addition to the built-in siren to the DSC Touch?
SS-300. If you are looking for a higher output, you can use the buzzer output to power a relay and then connect to a power supply module and siren. Our additional power supply kit is a great option to add everything you need other than the wire all at once. If you don’t have the ability to run wire we also have the RE116-U that has a wireless transmitter that would connect to the buzzer terminals and send a signal to the included wireless siren.
