Applications
The wireless Metasys products within a Metasys system are ideal for any location
where it is cost-prohibitive, difficult, or aesthetically unappealing to hardwire
between Metasys products. Examples of these locations include the following:
• hospitals, office buildings, university campuses, educational facilities,
correctional facilities, and other commercial structures with brick or solid
concrete walls and/or ceilings that impede hard-wired applications
• office buildings, retail stores, and other commercial real estate where tenant
turnover is frequent and temporary walls and ceilings are common
• museums, historical buildings, atriums, and other sites where building
aesthetics and historical preservation are important
• stadiums, arenas, gymnasiums, convention centers, airports, zoos, and other
locations with large, open spaces
• buildings with marble, granite, glass, mirrored, wood veneer, or other
decorative surfaces that present challenges to hard-wiring
• buildings with asbestos or other hazardous materials that must not be disturbed
• buildings with occupants sensitive to disruptions to business
• regions with high labor costs
• refrigerator/freezer storage containers
Applications to Avoid
Locations or applications that prohibit cellular telephones or Wireless Fidelity
(WiFi) systems are unsuitable for the wireless Metasys products. Examples
include:
• operating rooms or radiation therapy rooms
• validated environments
• UL 864 applications
• Department of Defense applications requiring Diacap certification (for
example, military bases and military hospitals)
Do not use the wireless Metasys products in applications that cannot tolerate
intermittent interference, or where:
• critical control features would impact life-safety or result in large monetary
loss, including secondary (backup) life-safety applications
• data centers, production lines, or critical areas would be shut down
• loss of critical control would result from loss of data from humidity or
temperature sensor communications
• operation of exhaust fans or Air Handling Units (AHUs) would impair a purge
or pressurization mode

• missing data would invalidate reporting required by the customer
• security points are monitored
ZFR1800 Series Wireless Field Bus System Overview
The ZFR1800 Series Wireless Field Bus System uses ZigBee technology for
wireless monitoring of HVAC equipment using the BACnet® protocol. The
system creates a wireless mesh network that enhances reliability and provides a
resilient self-healing capability by using automatically forming multiple
transmission paths for the data.
The Multidrop Serial Bus/Token-Passing (MS/TP) trunk and device limits for
supported Network Automation Engine (NAE) and Network Control Engine
(NCE) models are the same for hard-wired products, wireless products, or a
combination of hard-wired and wireless products.
The wireless mesh network is independent of any building infrastructure and does
not require any preexisting wireless infrastructure.
Any of the following Metasys® field controllers can be wirelessly enabled using a
ZFR1811 Wireless Field Bus Router:
• Field Equipment Controllers (FEC) - FEC16 or FEC26
• Advanced Application Field Equipment Controllers (FAC) - FAC26 or FAC36
• Input/Output Module (IOM) - IOM17, IOM27, IOM37, or IOM47
• Variable Air Volume (VAV) Modular Assembly (VMA) - VMA16
The wireless components are transparent to the supervisory controller and require
no special setup procedure to discover, map, and integrate the Wireless Enabled
Field Controllers (WEFCs).
Note: The devices within the ZFR1800 Series Wireless Field Bus System are
designed for indoor, intra-building applications only.
Note: A successful ZFR1800 Series Wireless Field Bus System requires that a
minimum wireless signal strength is maintained between system
components. Component location is an important part of system design.
Distance, metal objects, and other obstructions can reduce or completely
block the wireless signal transmissions.
IMPORTANT: A Network Engine reports an offline alarm within a fixed
period of time when an associated MS/TP field controller goes offline. For a
hard-wired FEC, FAC, IOM, or VMA field controller, this time period is usually
20 seconds. For a wireless-enabled FEC, FAC, IOM, or VMA field controller
within the ZFR1800 Wireless Field Bus system, this time period is 5 minutes.
An example of a ZFR1800 Series Wireless Field Bus System is shown in Figure 1.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 7
Figure 1: Example Metasys Network with ZFR1800 Wireless Field Bus System

ZFR1800 Series System Components
One ZFR1811 router is required per field controller. This pairing of a router and an
FAC, FEC, IOM or VMA16 field controller is a Wireless Enabled Field Controller
(WEFC).
A ZFR1800 Series system consists of:
• up to eight ZFR1810 Wireless Field Bus Coordinators per field bus
• up to 35 Wireless Enabled Field Controllers (WEFCs) per coordinator/
Personal Area Network (PAN)
• up to 100 WEFCs per field bus, depending on the network engine (32 with
NCE, 50 with NAE35)
• up to nine WRZ Sensors per WEFC
Note: Up to 100 total WEFC and WRZ Sensors per PAN
• additional ZFR1811 Wireless Field Bus Routers connected to MS-ZFRRPT-0
Repeater accessories, as required, acting as repeaters.
Note: Repeaters extend the wireless transmission distance of the BACnet data
communications, fill in any gaps within the wireless mesh network, and
provide multiple wireless data transmission pathways.
NAE and NCE
NAE35/45/55s and NCE25s (NxEs) are Web-enabled, Ethernet-based, supervisory
controllers that connect BAS networks to IP networks and the Web. NxEs provide
scheduling, alarm and event management, trending, energy management, data
exchange, dial-out capability, and password protection. With a computer running
Microsoft® Internet Explorer® Version 6.0 (or later), you can browse to a
configured NxE, and monitor and control BAS field devices in the Metasys Site
Management Portal on the NxE.
ZFR1810 Coordinator
A ZFR1810 Wireless Field Bus Coordinator provides a wireless interface between
an NAE35/45/55 or NCE25 supervisory controller on a wired BACnet MS/TP
network and wireless-enabled Metasys BACnet FEC/IOM/VMA field controllers.
Each wireless mesh network requires one ZFR1810 Coordinator, which initiates
the formation of the network. Each field bus can support up to eight ZFR1810
Coordinators.
A ZFR1810 Coordinator can operate from either of two power sources:
• a 24 VAC, Class 2 power source
• 15 VDC power provided from the FC Bus jack on any Field Equipment or
Supervisory Controller that is connected directly to the FC Bus
The ZFR1810 Coordinator features a remote-mount antenna and cable to allow
transmission when the ZFR1810 Coordinator is mounted inside a metal panel.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 9
ZFR1811 Router
A ZFR1811 Wireless Field Bus Router is used with any model FEC, IOM, or
VMA16 field controller to provide a wireless interface between a field controller
and:
• the NAE/NCE supervisory controller (by means of a ZFR1810 Coordinator)
• its associated WRZ Series Sensors
The ZFR1811 Router can also be used as a repeater to extend the range of the data
communications within the wireless mesh network, or to fill any gaps within the
mesh network, based on the physical layout of the wireless devices, obstacles, and
other characteristics of the installation site.
A ZFR1811 Router is powered directly from the connected field controller’s
15 VDC output. It can also be powered by the ZFRRPT repeater accessory to serve
as a stand-alone repeater, extending the range of the BACnet data communications
within the wireless mesh network.
Supported Field Controllers
The ZFR1800 Series Wireless Field Bus System enables wireless BACnet
connectivity between FAC, FEC, IOM, or VMA16 controllers and Network
Engines, including NAE/35/45/55 and NCEs.
In addition, the wireless field bus system provides wireless communication
between FEC, FAC, or VMA16 Controllers and WRZ Series Sensors. Each
wireless-enabled FEC, FAC, or VMA16 controller can support up to nine WRZ
Series Sensors, for multi-zone or averaging applications, or for high/low
temperature or humidity selection within a zone.
Note: The ZFR1811 Routers should be at the same Metasys system release
version as the wirelessly enabled FEC, IOM, or VMA16 field controller. If
there is a version mismatch, the Controller Configuration Tool (CCT)
provides indication of this, and the ZFR1811 Router automatically updates
during the main code download to the field controller. For information on
uploading or downloading the devices to match, refer to the Loading
Devices chapter of the Controller Tool Help (LIT-12011147).
Note: Some field controller applications do not support the occupancy/
temperature setback function.
Note: Wirelessly enabled FEC, FAC, and VMA16 field controllers can also use
hard-wired NS Series network sensors.
10 ZFR1800 Series Wireless Field Bus System Technical Bulletin
WRZ Series Sensors
Depending on the sensor model, the WRZ Series Sensors transmit temperature,
setpoint, humidity, occupancy status, and low battery conditions to an associated
field controller by means of a ZFR1811 Router. If the field controller is mapped to
the NxE, the data sent by the wireless sensor can be displayed.
Some applications that support the temperature or humidity control functions do
not support the occupancy/temperature setback function. Refer to a field
controller’s commissioning and operation literature to determine if the application
supports occupancy or temperature setback functions.
Note: Configure the Analog Inputs (AIs) on all WRZ Sensors as SA Bus devices
(the same as with hard-wired NS Series Sensors).
Note: The WRZ Series Sensors are designed for indoor, intra-building
applications only.
The WRZ Series Sensors require two 1.5 VDC AA alkaline batteries. The WRZ
sensors minimize power consumption by transmitting data only once per minute,
which yields an expected battery life of approximately 4 to 5 years.
ZFR Checkout Tool (ZCT)
The ZFR Checkout Tool is an optional tool, included with the installation of the
Controller Configuration Tool (CCT), that allows you to validate the wireless
connectivity and health of wireless devices within a ZFR1800 Series Wireless
Field Bus system, helping ensure a reliable mesh network is in place. You can use
the information provided by the ZCT to analyze and troubleshoot the wireless
mesh network created by a ZFR1800 Series System.
The ZCT gathers information by discovering the wireless field controllers and
wireless sensors on your network and analyzing their status and wireless
communication paths. The ZCT provides a simple report of wireless network
performance, including online status verification and wireless signal strength
information. The ZCT also provides wireless device lists, signal strength
information, and diagnostic measurements of the wireless mesh network.
Refer to the Using the ZFR Checkout Tool (ZCT) chapter of the Controller Tool
Help (LIT-12011147) for more information on the ZCT.
The ZCT requires a Universal Serial Bus (USB) adapter with ZigBee driver. For
information on this adapter and how to order it, see WRZ-SST-120 Wireless
Sensing System Tool.
Note: You must connect the adapter to the computer running CCT/ZCT before
attempting to scan the network.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 11
ZFR Wireless USB Dongle
The ZFR Wireless USB Dongle allows a computer to connect to a ZFR wireless
Field Bus for commissioning and downloading applications to wirelessly enabled
field controllers. The ZFR Wireless USB Dongle is also used with the ZFR
Checkout Tool for the purpose of analyzing a ZFR wireless mesh. The ZFR
Wireless USB Dongle requires a USB software driver, which is installed
automatically with CCT Release 5.3 or later. No user configuration is required.

Positioning the wireless Metasys products in the optimum locations with direct,
unobstructed, line-of-sight signal paths enhances the wireless signal strengths
between associated products and typically reduces the number of wireless products
required for your application. Figure 2 shows an example of a line-of-sight path for
a ZFR1800 Series Wireless Field Bus System.
Figure 2: Line of Sight
IMPORTANT: For special precautions regarding installing of a ZFR1800
Series system in a hallway, see Appendix C: Restricted Hallway Scenario.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 13
Required Materials
To perform the procedures for locating the components of your wireless Metasys
systems, you need the following:
• a detailed copy of the job site floor plans for the proposed application site with
the wall locations, column locations, mechanical rooms, elevator shafts,
stairwells, metal duct work, chases and risers, and other large metal
obstructions shown. The plans should also include the proposed
mechanical/HVAC zone layout and wireless device locations.
• a copy of the job site architectural and mechanical specifications with the
construction materials defined
• information on the dimensions, materials, and the general location of the
furnishings and other mobile content that is or will be installed in the occupied
application space (for example, file cabinets, shelving units, partitions,
displays, and other large metal items that can obstruct wireless signals)
• several different colored pens or markers for identifying zone and area
boundaries, wireless Metasys product locations, and signal obstructions.
Examples of major obstructions (MOs) include:
- interior building features such as elevator shafts, stairwells, mechanical or
electrical equipment rooms, equipment chases for HVAC, plumbing and
electrical risers, metal reinforced walls, concrete walls, cinder blocks, glass
walls with metal coating, and large metal-reinforced columns and pillars
- office equipment and furnishings such as computer racks, many rows of tall
file cabinets and book shelves, metal partitions, and displays
Examples of minor obstructions include several rows of cabinets or shelves,
metal light fixtures, multiple small pillars, sheetrock walls with metal or wood
studs, and glass walls without metal coating. For estimating purposes, several
small or minor obstructions can be grouped and considered a single MO.
General Guidelines for Locating Wireless Devices
Follow these general guidelines when locating your wireless products:
• Locate the wireless Metasys products so they are easily accessible.
• Locate the wireless products in direct, line of sight to as many other wireless
products within the same wireless network. The best distance is calculated by
locating the device on the same plane; however, it is possible to locate the
devices in an atrium as long as you maintain proper line of sight.
• Avoid metal, concrete, and brick obstructions (including equipment rooms and
elevator shafts) between the wireless products.
• Locate the ZFR1810 Coordinators in an elevated position in the space, above
furniture, cabinets, shelves, and other obstructions.
14 ZFR1800 Series Wireless Field Bus System Technical Bulletin
• All ZFR1811 Routers/Repeaters should be located in the same plane. For
example, if you are mounting the routers/repeaters above a dropped ceiling, all
routers/repeaters must be mounted above the dropped ceiling.
• Avoid configurations where a microwave oven is located between two wireless
devices. Avoid locating the ZFR1810 Coordinator near areas that may contain
a microwave oven, such as an employee break area or cafeteria. At a minimum,
ensure that no microwave ovens are within 6 m (20 ft) of a
ZFR1810 Coordinator.
• For best signal transmission on ZFR1810 Coordinators, which have an external
antenna, vertically orient the external antenna with at least 50 mm (2 in.)
exposed below and clear of any pipes, duct work, or other metal obstructions.
• For best signal transmission on ZFR1811 Routers and WRZ sensors, which
have internal antennas, vertically mount these products.
• Do not mount the wireless Metasys product in recessed areas, metal
enclosures, or shelving units unless the antenna can be positioned outside of
the recessed area or enclosure.
• Locate the wireless Metasys products that are within a wireless network on the
same floor or building level as the associated wireless products in the same
wireless network. For example, locate ZFR1810 Coordinators, ZFR1811
routers, and WRZ sensors on the same floor.
Guidelines for Locating Thermostats and Wireless Sensors
For best temperature sensing and control, follow the same best practices used to
locate a hard-wired temperature control, sensor, or thermostat when locating
wireless sensors:
• Avoid enclosed or recessed locations and locations behind curtains, doors, or
other obstructions to the controlled space.
• Avoid locations near entry foyers, doors, windows, supply air ducts, and pipes.
• Avoid locations that are exposed to drafts, direct sunlight, and other sources of
heat or cooling.
• Avoid locations where the wireless products could be exposed to excessive
vibration.
• Locate the wireless products on an interior wall where it is easily accessible, at
least 1.4 m (54 in.) above the floor, in an area where the temperature is
representative of the entire zone.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 15
Guidelines for Locating ZFR1800 Series System Components
Use information in this section to determine the optimum location for the
ZFR1810 Coordinator, ZFR1811 Routers, and WRZ Sensors in your ZFR1800
Series system applications and to estimate the number of additional repeaters
required.
• ZFR1811 Router locations are determined by the locations of the equipment
that are being controlled, the locations of the associated field controllers and
WRZ sensors, the physical characteristics of the applications space, and the
obstructions in the application space.
• Every WRZ Sensor should be within 15 m (50 ft) (recommended) of at least
two ZFR1811 Routers. (WRZ Sensors communicate only with routers.)
• Every ZFR1811 Router should be within 15 m (50 ft) (recommended) of at
least two other ZFR1811 Routers.
• The ZFR1810 Coordinator should be within 15 m (50 ft) (recommended) of at
least two ZFR1811 Routers.
• The ZFR1810 Coordinator should be at the center of the mesh network.
• The maximum distance between the ZFR1810 Coordinator and the farthest
ZFR1811 Router should be less than 76.2 m (250 ft).
IMPORTANT: If any WRZ Sensor, ZFR1811 Router, or ZFR1810
Coordinator is not within 15 m (50 ft) (recommended) of at least two other
ZFR1811 Routers, then use ZFR1811 Routers and ZFRRPT Repeater
accessories to function as repeaters to provide multiple wireless data pathways.
Wireless Signal Transmission Range
The effective transmission range/distance 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.
Transmission ranges between ZFR1800 Series products can be less than the
maximum distances shown in Table 3.

16 ZFR1800 Series Wireless Field Bus System Technical Bulletin
Selecting a PAN OFFSET for a Wireless Network
When selecting a PAN OFFSET for a wireless network, keep these points in mind:
• All devices within one wireless mesh network must be set to the same PAN
OFFSET.
• Select PAN OFFSETs that are unique for the site.
• Select PAN OFFSETs that result in unique MS/TP addresses for each ZFR1810
Coordinator on a trunk.
IMPORTANT: To avoid interference, assign a unique PAN OFFSET to each
wireless network in a building. Using a unique PAN OFFSET is particularly
important if you have PANs on adjacent floors of a building. Do not use the
same PAN OFFSET on multiple wireless networks in a building, even if the
PANs do not overlap.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 17
Detailed Procedures
Designing and Planning the ZFR1800 Series Wireless Field Bus
System
To ensure that the system is well-designed with good line-of-sight communication
paths and distances, see Location and Estimating Guidelines for planning
guidelines and restrictions before designing the system.
IMPORTANT: For special precautions regarding installing of a ZFR1800
Series system in a hallway, see Appendix C: Restricted Hallway Scenario.
In designing and planning the system, pay special attention to these points:
• Every WRZ Sensor should be within 15 m (50 ft) (recommended) of at least
two ZFR1811 Routers.
• Every ZFR1811 Router should be within 15 m (50 ft) (recommended) of at
least two other ZFR1811 Routers.
• The ZFR1810 Coordinator should be within 15 m (50 ft) (recommended) of at
least two ZFR1811 Routers.
• If any WRZ Sensor, ZFR1811 Router, or ZFR1810 Coordinator is not within
15 m (50 ft) (recommended) of at least two other ZFR1811 Routers, then use
ZFR1811 Routers and ZFRRPT Repeater accessories to function as repeaters
to serve this purpose of providing multiple wireless data pathways.
Note: WRZ sensors do not act as repeaters in the ZFR1800 Series Wireless
Field Bus System.
• The maximum distance between the ZFR1810 Coordinator and the farthest
ZFR1811 Router/Repeater should be less than 76.2 m (250 ft).
• Transmissions may use up to ten hops to transmit the signal to the coordinator;
transmissions that require more than ten hops can not reach the coordinator due
to network restrictions. A hop is any time a signal (information packet) moves
from one wireless device in the network to another wireless device in the
network.
18 ZFR1800 Series Wireless Field Bus System Technical Bulletin
• When a wireless mesh network forms, it uses up to five address depths in
assigning addresses for network communication. Refer to Figure 3. For more
information, see Appendix C: Restricted Hallway Scenario.
Figure 3: Address Depths
Note: Sensor devices cannot communicate directly with routers at depth 5. They
must be able to join the mesh at depth 4 or lower. For example, suppose a
WRZ sensor is physically located in the same room as its VMA with
Address K at depth 5. Since Address K cannot support any sensors directly,
the sensor must be within range of Device J at depth 4 and send its data to
Device J, which then forwards it to Address K.
Note: When a router joins the mesh, it does so based on the availability and signal
quality of other devices around it at that point in time. For example,
although Device L is physically located in the proximity of Device H, it
may get its address from Device J when it joins, making it a depth 5 device
and effectively limiting the growth of the mesh from that point.
Table 3 shows recommended and maximum indoor transmission ranges between
ZFR1800 Series products.
Table 3: Indoor Transmission Ranges
Range Type Transmission Distance
ZFR1810 Coordinator, WRZ Series Sensor
ZFR1811 Router/Repeater
Recommended 15.2 m (50 ft) 15.2 m (50 ft)
Maximum, Line of Sight 76.2 m (250 ft) 30 m (100 ft)
Indoor line-of-sight transmission ranges between products can be less than shown
in Table 3. The effective transmission distances and signal quality can vary per
application because of wireless signal absorption and reflection due to metal
obstructions, walls, ceilings, floors, and furniture found in typical building
interiors.
Note: Use the optional, battery-operated WRZ-SST-120 Wireless Sensing System
Tool with any model WRZ Series Sensor as a site survey tool to determine
the wireless signal strength between potential locations of ZFR1800 system
devices to survey your application and adjust ZFR1800 device locations
before permanently installing the devices. Refer to the WRZ-SST-120
Wireless Sensing System Tool Installation Instructions (Part No. 24-10563-
12) for more information on the tool.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 19
To locate the products on a copy of the job site building and HVAC plans:
1. Inspect the building plans floor by floor (section by section on each floor if
necessary), and locate your field controller and the intended locations of all
WRZ sensors. See Figure 4.

elevator shafts, metal equipment, equipment rooms, and duct work. See
Figure 4.
4. Locate the ZFR1810 Coordinator near the center of the space. See Figure 4.
You must locate the ZFR1810 Coordinator on the same floor or building level
as the associated ZFR1811 Routers. The ZFR1810 Coordinator’s antenna
should be in direct, unobstructed line-of-sight with a minimum of two
ZFR1811 Routers.

6. Add ZFR1811 Routers and ZFRRPT Repeater accessories to serve as repeaters
in order to fill in gaps and provide multiple wireless transmission paths
between products. See Figure 6.
Note: On your floor plan, if you have 15-m (50-ft) diameter (7.5-m
[25-ft] radius) circles that do not overlap with each other, add
ZFR1811 Routers (yellow circle) to serve as repeaters to fill in the gaps
so that every 15-m (50-ft) diameter (7.5-m [25-ft] radius) circle
overlaps with at least two other 15-m (50-ft) diameter (7.5-m [25-ft]
radius) circles.
Note: Typical job sites include a number of major and minor obstructions in
the final occupied space. The router quantity and locations are directly
affected by the number and location of obstructions.

22 ZFR1800 Series Wireless Field Bus System Technical Bulletin
Installing the ZFR1800 Series Wireless Field Bus System
Ensure that the physical installation of the ZFR1810 Coordinator and all the
ZFR1811 Routers/Repeaters have good line-of-sight communication paths, good
wired connections, and correct DIP switch settings per the guidelines in the
following documents:
• ZFR1810 Wireless Field Bus Coordinator Installation Instructions
(Part No. 24-10325-2)
• ZFR1811 Wireless Field Bus Router Installation Instructions
(Part No. 24-10325-10)
Pay special attention to these points:
• Mount all ZFR1811 Routers/Repeaters and the antenna of the ZFR1810
Coordinator in the same horizontal plane where possible, preferably just above
the ceiling panels. See Figure 7.

• 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.
24 ZFR1800 Series Wireless Field Bus System Technical Bulletin
• Connect the ZFR1811 Router to the correct jack on the field controller. Refer
to the ZFR1811 Wireless Field Bus Router Installation Instructions
(Part No. 24-10325-10).
• Select PAN Addresses that are unique within the site.
• Select PAN Addresses that result in unique MS/TP addresses for each
ZFR1810 Coordinator on a trunk. We recommend that you set the PAN
addresses of multiple ZFR1810 coordinators on the same trunk sequentially to
guarantee that each ZFR1810 has a unique MSTP Address on the bus.Refer to
the ZFR1810 Wireless Field Bus Coordinator Installation Instructions (Part
No. 24-10325-2).
Note: Once the PAN has been selected and other devices start to join the network,
do not change the PAN switches to another value and then back again.
Changing the PAN switches causes that device to clear its network
information, resulting in abandoned children. This can lead to duplicate
network (short ) addresses and controller online/offline toggling.

Installing the ZFR1810 Coordinator
To install the ZFR1810 Coordinator:
1. Select mounting locations for the ZFR1810 Coordinator and its external
antenna. See Location and Estimating Guidelines and Designing and Planning
the ZFR1800 Series Wireless Field Bus System.
2. Mount the ZFR1810 Coordinator and its external antenna. Refer to the
ZFR1810 Wireless Field Bus Coordinator Installation Instructions
(Part No. 24-10325-2).
Note: The connection from the antenna cable to the ZFR1810 is intended to
be made only once. Avoid any repeat removals and reinsertions that
may affect wireless connection integrity and unit performance.
Note: Remove the ZFR1810 Coordinator from its mounting base before
connecting the antenna cable to the ZFR1810 Coordinator.
3. Set the ZFR1810 Coordinator’s End-of-Line (EOL) switch based on MS/TP
network installation guidelines. Refer to the ZFR1810 Wireless Field Bus
Coordinator Installation Instructions (Part No. 24-10325-2).
4. Set the ZFR1810 Coordinator’s PAN OFFSET Switch per the job drawings
(for example, Floor 1 = 1, Floor 2 = 2, and so forth). The MS/TP address of the
ZFR1810 Coordinator is 120 plus the sum of the first three values of the
PAN OFFSET DIP switch, giving an MS/TP address range of 120 to 127. Only
the values associated with the first three switch positions (right to left) affect
the MS/TP address. In Figure 9, for example, the PAN OFFSET is configured
to 13 with values 1, 4, and 8 set to the ON position. The sum of these values is
5, and the MS/TP address of the ZFR1810 Coordinator would then be 120 + 5,
which equals 125.
IMPORTANT: The PAN OFFSET switch setting must be the same for all the
ZFR1800 Series and WRZ devices on the same wireless mesh network.
IMPORTANT: To avoid MS/TP address conflicts, do not connect the
ZFR1810 Coordinator to the field bus before setting the PAN OFFSET switches.
IMPORTANT: To avoid interference, assign a unique PAN OFFSET to each
wireless network in a building. Using a unique PAN OFFSET is particularly
important if you have PANs on adjacent floors of a building. Do not use the
same PAN OFFSET on multiple wireless networks in a building, even if the
PANs do not overlap.
IMPORTANT: For multiple ZFR1810 Coordinators on a field bus, use
sequential PAN OFFSETs to ensure unique MSTP addresses.
ZFR1800 Series Wireless Field Bus System Technical Bulletin 27
5. Wire the MS/TP FC Bus between the ZFR1810 Coordinator and the NAE or
NCE. Refer to the ZFR1810 Wireless Field Bus Coordinator Installation
Instructions (Part No. 24-10325-2).
6. Connect the power supply to the ZFR1810 Coordinator, but do not apply
power.
Installing the ZFR1811 Router Used with a Field Controller
The ZFR1811 Router connects to each FEC/IOM/VMA field controller as
specified in Table 4. For additional information on the appropriate connection
point, refer to the ZFR1811 Wireless Field Bus Router Installation Instructions
(Part No. 24-10325-10) and the appropriate installation instructions of each
controller.
IMPORTANT: Switch 128 on the FC Bus address switch block enables the
FEC/FAC/IOM/VMA field controller to operate in a wireless mode using the
ZFR1800 Series Wireless Field Bus system. Set the field controller’s Switch
128 to the ON position for wireless operation. Set the field controller’s Switch
128 to the OFF position for hard-wired operation.
To install the ZFR1811 Router used with a field controller:
1. Select mounting locations for the ZFR1811 Router. Refer to the job plans and
see Location and Estimating Guidelines and Designing and Planning the
ZFR1800 Series Wireless Field Bus System.
2. Set the ZFR1811 Router PAN OFFSET Switch to match the ZFR1810
Coordinator PAN OFFSET according to the job plans (for example,
Floor 1 = 1, Floor 2 = 2, and so forth).
IMPORTANT: The PAN OFFSET switch setting must be the same for all the
ZFR1800 Series and WRZ devices on the same wireless mesh network.
IMPORTANT: Do not connect the ZFR1811 Router to the field controller
before setting the PAN OFFSET switches.
IMPORTANT: To avoid interference, assign a unique PAN Offset to each
wireless network in a building. Using a unique PAN OFFSET is particularly
important if you have PANs on adjacent floors of a building. Do not use the
same PAN Offset on multiple wireless networks in a building, even if the
PANs do not overlap.
3. Mount the ZFR1811 Router. Refer to the ZFR1811 Wireless Field Bus Router
Installation Instructions (Part No. 24-10325-10).
4. At each FEC/FAC/IOM/VMA16 WEFC, set the MS/TP Address switch per the
job plans. Set the MS/TP Address switch 128 to the ON position. This
procedure enables the field controller’s wireless mode and allows it to work
with a ZFR1811 Router.
