ZFR1811 Wireless Field Bus Router Installation Instructions 1
Refer to the QuickLIT Web site for the most up-to-date version of this document.
Application
A ZFR1811 Wireless Field Bus Router is used with
Field Equipment Advanced Application Controllers
(FACs), Field Equipment Controllers (FECs), Input/
Output Modules (IOMs), and Variable Air Volume
Modular Assembly (VMA) Series field controllers.
The ZFR1811 Router provides a wireless interface
between:
• a field controller and the supervisory controller (by
means of a ZFR1810 Coordinator)
• a field controller and associated WRZ Series
Wireless Room Sensors
Additionally, the ZFR1811 Wireless Field Bus Router
can be used as a repeater in WRZ-7860-0 One-to-One
Wireless Room Temperature Sensing System. For
more information, refer to the WRZ Series One-to-One
Wireless Room Sensing System Technical Bulletin
(LIT-12011641).
Up to nine WRZ Series Sensors can be associated
with a single field controller. In multi-sensor
applications, the ZFR1811 Router passes all the
sensor data to an FAC, FEC, IOM, or VMA controller,
which can be configured to either average the sensors’
input or select the highest or lowest sensed condition
for control of the target zone.
A ZFR1811 Router is powered directly from the
connected field controller’s 15 VDC output.
The Router can also be powered by the power supply
in the Repeater Accessory Kit to serve as a
stand-alone repeater, extending the range of the
communications within the wireless mesh network.
Refer to the ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295) or the
ZFR1800 Series Wireless Field Bus System Quick
Reference Guide (LIT-12011630) for information on
commissioning and configuring a ZFR1800 Series
Wireless Field Bus System for operation.
Use the ZFR1811 Wireless Field Bus Router only to
provide an input to equipment under normal
operating conditions. Where failure or malfunction of
the ZFR1811 Router could lead to personal injury or
property damage to the controlled equipment or
other property, additional precautions must be
designed into the control system. Incorporate and
maintain other devices, such as supervisory or
alarm systems or safety or limit controls, intended to
warn of or protect against failure or malfunction of
the ZFR1811 Router.
IMPORTANT: The ZFR1800 Series Wireless Field
Bus System is not designed or intended for use in
mission-critical or life/safety applications.

ZFR1811 Wireless Field Bus Router Installation Instructions 3
Mounting
When mounting the ZFR1811 Router to an enclosure,
mount it to the top, bottom, or side of the enclosure. Do
not mount the ZFR1811 Router in a horizontal
orientation. See Figure 2.
Location Considerations
Follow these guidelines when locating a ZFR1811
Router within a ZFR1800 Series System.
• Locate the ZFR1811 Router so that it is easily
accessible.
• For best signal transmission, vertically orient the
ZFR1811 Router with the flag end of the router
exposed below (and clear of) any pipes, duct work,
or other metal obstructions by at least 50 mm
(2 in.). Do not mount the ZFR1811 Router in a
horizontal orientation. See Figure 2 and Figure 3.
• 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 ZFR1811 Router shows poor signal
strength, you may be able to improve the signal
strength by rotating the ZFR1811 Router.
• Locate the ZFR1811 Router in line-of-sight with as
many ZFR1811 Routers and WRZ Sensors as
possible.
• Do not mount the ZFR1811 Router in recessed
areas, metal enclosures, or shelving units.
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).

Wireless Signal Transmission Considerations
Line-of-sight transmission ranges between a
ZFR1810 Coordinator, ZFR1811 Router, and/or a
WRZ Sensor can be less than the maximum distances
shown in Table 1. The effective transmission range for
indoor applications varies because of wireless signal
absorption and reflection due to metal obstructions,
walls (or floors), and furniture found in typical building
interiors.
Wiring
Wiring Considerations and Guidelines
Wiring with an FEC or VMA16 Series Field
Controller
Connect the ZFR1811 Router to the field controller as
shown in Table 2. This connection provides both power
and communication to the ZFR1811 Router.
Note: When using a field controller in a wireless field
bus network, ensure that the DIP switch for Address
128 is set to the ON position.

IMPORTANT: Do not connect supply power to the
ZFR1811 Router before finishing wiring and
checking all wiring connections. Short circuits or
improperly connected wires may result in permanent
damage to the Router.
IMPORTANT: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations. The ZFR1811 Router is a
low-voltage (less than 30 VAC) device. Do not
exceed the ZFR1811 Router’s electrical ratings.
IMPORTANT: Prevent any static electric discharge
to the ZFR1811 Router. Static electric discharge can
damage the ZFR1811 Router and void any
warranties.
IMPORTANT: Do not connect the ZFR1811 Router
to the power supply before setting the PAN OFFSET
switches.

more information on using the ZFRCBL accessory,
refer to the Wireless Commissioning Converter
Installation Instructions (Part No. 24-10108-2).
Port Swap on Wireless-Enabled VMA1610/1620s
On the VMA1610/1620 models, when the 128 bit
switch on the address DIP switch is turned ON (to
enable wireless operation), the FC and SA bus are
swapped internally. All connections that were SA bus
(RJ-12 and terminal blocks) are now FC bus
connections. The terminal block connections marked
for the FC bus are now connected internally to the
SA bus.
If you have an installation that calls for a wired IOM
connected to the SA Bus of a wireless-enabled
VMA1610/1620 field controller, connect the IOM to the
FC Bus Terminals (which are really the SA Bus
terminals on a VMA1610/1620 in wireless mode) as
indicated in Figure 6 and Figure 7.
Note: The VMA1615/1630 controller have RJ-12
connectors on the FC bus and SA bus. These
controllers do not require port swapping when in
wireless mode.

Setup and Adjustments
Set the PAN Offset value of the ZFR1811 Router using
the DIP switches (located on the back of the cover) to
configure the ZFR1811 Router to communicate on the
wireless mesh network. See Figure 1 and Figure 8.
The value equals the sum of the numbers set to ON.
For example, if the DIP switches labelled 1, 4, and 8
are set to ON, the PAN Offset value is 13
(1 + 4 + 8 = 13).
When selecting a PAN Offset value for a wireless
system:
• Use a unique PAN Offset value for each wireless
mesh network at a job site.
• Use the same PAN Offset value for each wireless
device in a wireless mesh network - the
ZFR1810 Coordinator and each associated
ZFR1811 Router and WRZ Sensor.
Note: On some date code labels, the switch position
numbers on the bottom of the dip switch are reversed.
In either case, the switch positions are always read
right to left.
IMPORTANT: Ensure that the PAN OFFSET
switches are set to the same value for each
ZFR1810 Coordinator, ZFR1811 Router, and
WRZ Sensor in a mesh network.
IMPORTANT: Do not connect the ZFR1811 Router
to the power supply before setting the PAN OFFSET
switches.
IMPORTANT: On the MS/TP Address switch block
of the associated FEC/IOM/VMA16 Field Controller,
set switch 128 to ON for use with a ZFR1811 Router.

Troubleshooting
Use the Status Light-Emitting Diode (LED) (see
Figure 1) along with the information in Table 3 to
troubleshoot the ZFR1811 Router.
Wireless Signal Strength
A wireless signal strength indication LED displays the
reception strength of the transmissions between the
ZFR1810 Coordinators, ZFR1811 Routers, and the
WRZ Series Sensors. This LED helps determine the
network connectivity status when selecting locations for
the devices during system installation.
Wireless transmissions between ZFR1810
Coordinators and ZFR1811 Routers occur as needed.
Wireless transmissions between ZFR1811 Routers and
WRZ Sensors occur approximately every 60 seconds
or when the occupancy button on the WRZ Sensor is
pressed. Refer to the WRZ Series Wireless Room
Temperature Sensors Installation Instructions (Part No.
24-10332-2) for more information.
Approximately once every 10 seconds, the Signal
Strength LED flashes to indicate the strength of the
signal received from neighboring devices. See Table 3.
Note: The Signal Strength LEDs on all the ZFR1811
routers in a network extinguish after approximately
2 hours of normal operation, making the ZFR1811 less
distracting when installed in an open area. To re-enable
the ZFR1811 LEDs for troubleshooting purposes,
perform a scan using the ZFR Checkout Tool (ZCT).
Alternatively, push the Network Optimize/Reform Push
Button on the ZFR1810 coordinator for 0-5 seconds.
Note that if you press this button more than 5 seconds
a Network Optimize or Reform is initiated.
Refer to the ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295) for more
information on determining the signal strength between
ZFR1800 Series devices in your application.
