Mounting
Location Considerations
Follow these guidelines when locating a ZFR1810
Coordinator within a ZFR1800 Series system.
•
Locate the ZFR1810 Coordinator so that it is easily
accessible.
•
For best signal transmission, vertically orient 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 the antenna in a horizontal orientation.
•
Due to the nature of the radio frequency waves, a
wireless device may have significantly different
signal strengths if its position changes relative to
another wireless device or if its environment
changes. If a ZFR1810 Coordinator shows poor
signal strength, you can improve the signal
strength by moving the device’s antenna a couple
of inches in either horizontal direction.
•
Locate the ZFR1810 Coordinator’s antenna in
line-of-sight with as many ZFR1811 Routers as
possible.
•
Do not mount the ZFR1810 Coordinator’s antenna
in recessed areas, metal enclosures, or shelving
units.
Follow these additional guidelines when installing a
ZFR1810 Coordinator:
•
Locate the ZFR1810 Coordinator near the center
of the associated array of ZFR1811 Routers.
•
At a minimum, position a ZFR1810 Coordinator
within 15.2 m (50 ft) of at least two
ZFR1811 Routers.
•
At a minimum, position all ZFR1811 Routers within
15.2 m (50 ft) of at least two other ZFR1811
Routers or one ZFR1811 Router and the ZFR1810
Coordinator.
•
Locate the ZFR1810 Coordinator on the same floor
as the associated ZFR1811 Router and
WRZ Series Sensors.
•
Test the transmission signal strength between the
ZFR1810 Coordinator and the associated
ZFR1811 Router and WRZ Series Sensors to
ensure a reliable mesh network is in place. For
more information, see the
ZFR1800 Series
Wireless Field Bus System Technical Bulletin
(LIT-12011295).
•
Avoid metal obstructions and concrete or brick
walls between the ZFR1810 Coordinator and the
associated ZFR1811 Router and WRZ Series
Sensors.
•
Avoid configurations where a microwave oven is
located between two wireless devices. At a
minimum, ensure no microwave ovens are within
6 m (20 ft) of a ZFR1810 Coordinator.
Note:
For detailed information on location guidelines
for a ZFR1800 Series system, and for estimating the
number of ZFR1811 Routers needed as repeaters for
extending wireless transmission range, refer to the
ZFR1800 Series Wireless Field Bus System Technical
Bulletin (LIT-12011295)
