Note: Door Controls can be installed within 30 meters
of the Controller or within 30 meters of any other Door Control
as each Door Control will function as a repeater. Each Door Control
transmits data to/from the Controller. These distances are a guideline.
The actual communication range depends on building shape and
construction methods used.
