To locate the transmitter in wireless applications, follow these guidelines:

  • Locate the transmitter on the same building level as the nearest ZFR or ZFR Pro Series Router, or WRZ-78x0-0 Receiver.
  • For best signal transmission, locate the transmitter at least 2 in. (51 mm) away from any metal obstructions.
  • Wherever possible, locate the transmitter in the direct line-of-sight to the ZFR or ZFR Pro Series Router, or WRZ-78x0-0 Receiver. Signal transmission is best if the path between the transmitter and the router or receiver is as direct as possible. Line-of-sight is preferred but not required, as long as the path is not blocked by large metal objects.
  • Avoid metal obstructions, this includes equipment rooms and elevator shafts, and concrete or brick walls between the transmitter and the ZFR or ZFR Pro Series Router, or WRZ-78x0-0 Receiver.
  • Do not mount the transmitter closer than 2 ft (0.61 m) or farther than 100 ft (30 m) from the ZFR or ZFR Pro Series Router, or 150 ft (45 m) from the WRZ-78x0-0 Receiver.
  • The indoor line-of-sight transmission range between the transmitter and the ZFR or ZFR Pro Series Router is 50 ft (15 m).
