When selecting the installation locations of the Master Units, consider the following conditions:
• 24 VDC power supply can be supplied to the Master Unit
• To set the Master Unit at a relatively high position. When installing the Master Unit on the floor, the
communications distance becomes short.
• Installation at a higher position will be installed in a more open space. As a result, radio waves will be
more easily reachable without being affected by obstacles.
• Do not place a metal object around the antenna.
Metal objects reflect radio waves, so if there is a metal object around the antenna, the radio waves in
a specific direction may become weak.
Keep the antenna away from the metal object.
