Loud Out Door Siren

Hello group
Im new here and just set up my new ST I need a loud and compatible outdoor siren,I have seen The Swann ONE outdoor siren does anyone know if this will work with ST or does anyone have a suggestion.

The simplest way is to use a regular 12V alarm siren powered by a 12V power supply plugged into a Z-Wave plug-in module.


where could I buy this is there an amp to drive it what would make it loud

You don’t need amp. Just connect it to 12V, 1A DC power supply and plug it into any Z-Wave appliance module

where can I get that power supply

Have you tried Amazon? :slight_smile:
