For the optimal operation of communication between NOW devices, we recommend you to place the Connection Unit in the center of the System, so that the communication (radio frequency protocol) is uniform between all the installed devices.
In general, the range of the Connection Unit is about 10 meters, however the width could be reduced due to the structure of the building (e.g. thick or stone walls, presence of metal/shielding panels).
If you need to extend or strengthen the signal, you can add one Connection Unit to your system and activate it in Repeater mode.
