A sensor/switch that can show if alarm is armed

Hi All

I am looking for a wifi/zigbee based device that can change a state based on whether my alarm is armed or not. From the alarm’s instruction manual it will put out a 12V reading for an armed state, and drop back to 0V once disarmed. So, I am looking for something to wire in there that will be turned ‘on’ when the alarm is armed, and turned ‘off’ when disarmed.

I am not from the US, but will take all inputs I can get and then I will see if I can source them locally.

Thanks in advance for any help!
