• For best signal transmission, vertically orient the ZFR1811 Router/Repeater or
the ZFR1810 Coordinator’s antenna with at least 50 mm (2 in.) exposed below
(and clear of) any pipes, duct work, or other metal obstructions.
Do not mount a ZFR1811 Router/Repeater or the ZFR1810 Coordinator’s
antenna in a horizontal orientation.
When mounting the ZFR1811 Router/Repeater or the ZFR1810 Coordinator’s
antenna to an enclosure, mount it to the top, bottom, or side of the enclosure.
See Figure 8.
• Do not mount the ZFR1810 Coordinator’s antenna or the ZFR1811 Router/
Repeater in recessed areas, metal enclosures, or shelving units.
• Locate the ZFR1810 Coordinator’s antenna and the ZFR1811 Router/Repeater
in line-of-sight with as many ZFR1811 Routers/Repeaters and WRZ Sensors as
possible. Ensure that the line-of-sight is clear of metal studs or ductwork.
• Locate the ZFR1810 Coordinator on the same floor as the associated ZFR1811
Routers/Repeaters and WRZ Sensors.
