Application

Use the ZFR1812 Wireless Field Bus Router only to
provide an input to equipment under normal
operating conditions. Where failure or malfunction of
the ZFR1812 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 ZFR1812 Router.

IMPORTANT: The ZFR1800 Series Wireless Field
Bus System is not designed or intended for use in
mission-critical or life/safety applications.

A ZFR1812 Wireless Field Bus Router is used with
Advanced Application Field Equipment Controllers
(FACs), Field Equipment Controllers (FECs), Input/
Output Modules (IOMs), and Variable Air Volume
Modular Assembly (VMA) Series field controllers.

The ZFR1812 Router provides a wireless interface
between:

• a field controller and the supervisory controller (b
ans of a ZFR1810 Coordinator)

me

• a field controller and associated WRZ Seri

Wireless Room

Additionally, the ZFR1812 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 ZFR1812 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.

Physical Features and Dimensions, mm (in.)

Follow these guidelines when installing a
ZFR1812 Router:

• Transport the ZFR1812 Router in the original
container to minimize vibration and shock damage.

• Do not drop the ZFR1812 Router or subject it to
physical shock.

Materials and Special Tools Needed

• A 1.5 mm (1/16 in.) Allen wrench or a Johnson
Controls® T- 4000-119 Allen-He ad Adjustment Tool
is required for tightening or loosening the security
screw

Dimensions

See Figure 1 for physical features and dimensions of
the ZFR1812 Router.

The ZFR1812 can be mounted directly to drywall with
drywall anchors. Both the standalone and repeater kit
versions of the ZFR1812 include a 10 foot long RJ12
cable hardwired to the device. The Repeater Kit
versions (the ZFRRPTK-H1 and ZFRRPTK-H2)
provide additional flexibility for mounting such as a
separate power supply. ZFR1812s can be flush
mounted to a wall or ceiling, or mounted on a 4x4 box
using a standard mudplate. When mounting the
ZFR1812 Router to an enclosure, mount it to the top,
bottom, or side of the enclosure. For floor mount
unitary equipment, mounting on top where books or
other items may be placed is not ideal. See Location
Considerations.

Mounting Directly to Drywall with Drywall Anchors

- ZFR1812

1. Separate the plastic base and circuit board
assembly (cover). Do not remove the security
screw from the cover. See Figure 2.

IMPORTANT: The label showing the unit MAC
address is on the plastic base of the unit. Be sure to
keep the plastic base and circuit board assemblies
together so the correct MAC address is shown.

Mounting

Note: These instructions are for mounting new

ZFR1812s rather than retrofitting factory-mounted
routers.

2. Determine where to secure the plastic base to the
surface using the mounting holes and supp lie d
screws. A template (Figure 11) is provided at the
end of this document to help you place the
mounting holes.

3. Set the DIP switches. (See

Setup and Adjustments

4. Reattach the circuit board assembly in the plastic
base being careful not to pinch the a t tached RJ-12
cable.

5. Tighten the security screw to prevent tampering
using a 1.5 mm (1/16 in.) Allen wrench or a
Johnson Controls® T-4000-119 Allen-Head
Adjustment Tool. Use caution when tightening the
screw to avoid stripping the plastic threads in the
ZFR1812.

Mounting the ZFRRPTK-H1

The ZFRRPTK-H1 is intended for flush wall mount or
ceiling mount applications. In addition to the ZFR1812,
it includes a power supply, a 10 ft RJ-12 cable for
connecting the power supply, and an adapter to
connect the power supply to the RJ-12 cable.

address is on the plastic base of the unit. Be sure to
keep the plastic base and circuit board assemblies
together so the correct MAC address is shown.

2. Decide whether you are mounting on a wall or
ceiling.

a. For flush wall mount applications, determine

where to secure the plastic base to the surface
using the mounting holes and supplied screws.
A template (Figure 1 1) is provided at the end of
this document to help you place the mounting
holes.

b. For ceiling mount applications, mount the

ZFR1812 to the grid between the tiles. Ther e
are a number of ceiling mounting clips
available from third parties which can be used.
Make sure to match the clip you purchase to
the grid in the location where you are doing the
installation. Ceiling grid dimensions and offsets
vary, so using an incorrectly sized clip may
prevent mounting the ZFR1812 flush for a
professional appearance. A hole is provided in
the base of the assembly for this purpose
(Figure 3).

IMPORTANT: If you are using a ceiling mounting clip
you must make sure that no part of the clip makes
contact with the circuit board assembly when installed.

3. Assemble the external power and adapters as
necessary (Figure 4).

a. The 24 VAC to 15 VDC power supply (1) uses

screw terminals to attach to a 24 volt source.

b. The adapter connects the 15 VDC output of the

power supply to an RJ12 adapter (2). Plug this
adapter directly to the cable coming from the
ZFR1812 through a connector (3 ).

c. This connector (3) is then used to connect to

the 10 ft RJ-12 cable which is attached to the
ZFR.

Note: Any inline adapter used to extend the
connection of the ZFR1812 to a controller or po wer
must be a straight through adapter instead of
crossover.

4. Set the DIP switches. See Setup and Adjustments

5. Reattach the circuit board assembly in the plastic
base.
