Using Honeywell Ademco 748 Siren with Smart things

Hi. I have a great (and very loud) Honeywell Ademco 748 siren that I wish to continue using. Can anyone talk/walk me though how I would go about getting this to work with the smartthings hub. Thinking it may be possible to power it from a smart things wall outlet but I suspect that something else may be required.

These sirens just need 12V DC to operate. The easiest way is to power them from a 12V 1A DC power brick and plug it into any Z-Wave or Zigbee appliance module (on/off, not dimming) that can be controlled by SmartThings.

Something like this?

Yep, that should do it.
