Johnson Controls ZFR1831 Pro Series Bedienungsanleitung
ZFR1831 Pro Series Wireless Router
Installation Guide
Introduction
The ZFR1831 Wireless Router (ZFR1831) is a component of the ZFR183x Pro Series Wireless Field Bus
System which provides BACnet IP connectivity to compatible Johnson Control Field Controllers, VAV
Controllers, Thermostats and Sensors over a wireless mesh network. The ZFR1831 can be used as a
wireless Network Coordinator, a Field Controller Router or Stand-alone Repeater.
Applications
Important: Where failure or malfunction of an ZFR1831 or loss of communications due to
wireless interference 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 a
ZFR1831.
Important: The WRG1830/ZFR183x Series Wireless Field Bus System is not designed or
intended for use in mission-critical or life/safety applications.

Installation
CAUTION
Risk of Electric Shock
Disconnect the power supply before making electrical connections to avoid electric shock.
ATTENTION
Risque de décharge électrique
Débrancher l’alimentation avant de réaliser tout raccordement électrique afin d’éviter tout risque de
décharge électrique.
Important: Do not insert tools into the housing. Be careful not to damage any components
when pushing the tabs on either side of the sensor.
Important: Do not remove the printed circuit board (PCB). Removing the PCB voids the
product warranty.
Important: The modular phone jack and screw terminal connections cannot be used
simultaneously.
Location Considerations
Follow these guidelines when locating an ZFR1831 within an ZFR183x Pro Series Wireless Field Bus
system:
• The ZFR1831 wireless router can be installed on wall, wall box, conduit, or ceiling grid.
• Do not mount inside metal enclosures or on surfaces that can block RF signals.
• Locate the ZFR1831 so that it is easily accessible.
• For best signal transmission, orient the ZFR1831 with at least 50 mm (2 in.) exposed below
and clear of any pipes, duct work, or other metal obstructions.
• Locate the ZFR1831 in line-of-sight with as many wireless controllers as possible. At a
minimum, two other ZFR1831 Routers.
• Do not mount the ZFR1831 in recessed areas, metal enclosures, or shelving units.
• If feasible, mount the ZFR1831 outside of mechanical rooms, as many mechanical rooms
excessively attenuate the radio signal.
• Position WRZ Series sensors within 15m (50ft) of any ZFR1831 Router with the same PAN
setting.
ZFR1831 Pro Series Wireless Router Installation Guide2
Johnson Controls - CONFIDENTIAL
• Position ZFR1831 Routers within 75m (250ft) of other Routers with the same PAN setting.
• Locate all wireless devices that have the same PAN setting on the same floor (ZFR1831's,
TEC3000's, WRZ's). Communications between floors is typically not advised due to the
attenuation of the signal through the decking.
• Avoid metal obstructions and concrete or brick walls between the ZFR1831 and the associated
wireless devices.
• 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 an ZFR1831 or any wireless
controllers or WRZ Sensor.
Note: For detailed information on location guidelines for an WRG1830/ZFR183x Series system,
and for estimating the number of ZFR1831 Routers needed as repeaters for extending
wireless transmission range, refer to the applicable WRG1830/ZFR183x Series Wireless Field Bus
System Technical Bulletin.
Parts included

Wireless signal transmission considerations
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.
Transmissions may use up to 30 hops to transmit a message to the coordinator. In a well- designed
system, the layout design should minimize the required hops based on the recommended
transmission ranges and should typically be kept below five. Information on determining the
numbers of hops being used is covered in the WRG1830 Wireless Gateway Users Guide (LIT-12013550).
The WRZ sensors list a lower line of sight range because they transmit at a lower power (10mW)
than the wireless routers (100mW) and are typically mounted in the occupied spaces where there is
more attenuation due to occupants and furnishings.

Indoor line-of-sight transmission ranges between products can be less than those in the table
above. The effective transmission distances and signal quality can vary for each application because
of wireless signal absorption and reflection due to metal obstructions, walls, ceilings, floors, and
furniture found in typical building interiors.
Transmission ranges between ZFR183x Pro Series products can be less than the maximum
distances shown in the table above.
Wiring
Wiring considerations and guidelines
Wiring Considerations and Guidelines
Follow these guidelines when wiring a ZFR1831:
• Route the wires at least 50 mm (2 in.) away from the sides of the ZFR1831 housing.
• Provide slack in the wires. Keep wires routed neatly around the ZFR1831 to promote good
ventilation, LED visibility, and ease of service.
Important: Do not connect supply power to the ZFR1831 before finishing wiring and checking
all wiring connections. Short circuits or improperly connected wires may result in permanent
damage to the ZFR1831.
Important: Use copper conductors only. Make all wiring in accordance with local, national,
and regional regulations. The ZFR1831 is a low-voltage (less than 30 VAC) device. Do not
exceed the ZFR1831’s electrical ratings.
Important: Prevent any static electric discharge to the ZFR1831. Static electric discharge can
damage the ZFR1831 and void any warranties.
Important: Do not connect the ZFR1831 to the power supply before setting the PAN OFFSET
rotary switches.
Power input and communication
Using as a Router connected to a Field Controller
1. Follow the mounting instructions above for mounting to either wall, conduit, or ceiling grid.
2. Connect the ZFR1831 to a compatible Field Controller using either the RJ-12 connector
(shown) or the 4 pin FC Bus terminal connection. This connection provides both power and
communication to the ZFR1831.

Setup and adjustments
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 setting.
• Select PAN settings that are unique for the site.
• The AREA rotary switch should be set to 0.

Important: To avoid interference, assign a unique PAN setting to each wireless network in a
building. Using a unique PAN setting 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.
