Does alarm panel work when there's no WIFI?

Hi, I'm wondering if I configure the alarm triggers in Smartthings, will the Konnected alarm panel will still function and sound the alarm/sirens even when the Wifi is down? Or, does it always rely on the Wifi connection to check with smartthings on what to do when motion is detected?

Hi, I am interested to know this as well. 


If this is the case, it is really good. Even with a power failure (no internet/router), but we can use the battery back up to sound the alarm. Also, if we can use a tablet (powered by the backup battery power) which has sim card, it is possible to send a notification. Will this work?
