Note:

To activate any of the above functions, change the corresponding command bit from Off to On. The panel does not reset the command bit, so you have to reset the command bit before commanding the panel to perform the same function again. Keep the state of the command bit long enough so the panel can detect the change. The best way is to use the corresponding acknowledge bit in the Command Status Word. The panel turns on the acknowledge bit when it detects the change. It is safe to reset the command bit when the acknowledge bit turns on. The panels turns off the acknowledge bit when it sees the command bit turn off.
