Motion sensor configured to 'Away' sets off alarm even when alarm panel is set to 'Home' monitoring state. The external siren will also not turn off when the alarm panel is 'Disarmed'

Following the suggestion below will resolve the issue.

1. Reset and re-add the external siren

• Click here to see a video on how to reset the siren and re-add the external siren to the alarm panel

2. Delete the pir sensor(s) from the alarm panel

• Make sure both PIR sensors are turned off.
• Turn one motion sensor on and add it to the alarm panel (Set Mode to: away), once added, turn the motion sensor off
• Turn the second motion sensor on and add it to the alarm panel (Set Mode to: away).
• You can now turn the other motion sensor back on.
  The reason why the Motion sensors need to be turned off is unlike the door/windows sensors, motion sensors are always 

3. Reboot the alarm panel. Click Here to see a video on how to reboot the alarm panel

4. After you have rebooted the alarm panel, perform a test in 'Home' mode with the motion sensor.

Note: If you are having a similiar issue with the door/window sensors you can follow the same instructions above, however there is no need to turn off the sensors as only the motion sensor can be turned off and on.
