FAC2612-2 Advanced Application Field
Equipment Controller Installation Guide
Application
The FAC2612-2 Advanced Application Field
Equipment Controller (FAC) is part of the Metasys®
system Field Equipment Controller family. The
FAC26 Series controllers run pre-engineered and
user-programmed applications. They provide the
inputs and outputs required to monitor and control
equipment.
FAC26 field controllers operate on an RS-485
BACnet® MS/TP Bus as BACnet and integrate into
the web-based Metasys® system.
FAC26 controllers include an integral real-time clock,
which enables the controllers to monitor and control
schedules, calendars, and trends; and operate for
extended periods of time as stand-alone controllers
when offline from the Metasys system network.
The FAC2612-2 model operates on VAC supply
power.
Switchable communications protocol
The Metasys® system FEC Family Controllers and
network sensors communicate using either the
standard BACnet protocol, based on the ANSI/
ASHRAE 135-2008, or the BACnet/IP protocol. The
BACnet protocol is a standard for ANSI, ASHRAE, and
the International Standards Organization (ISO) for
building controls.
FEC, VMA16, VMA18, and most IOM field controllers
are BTL-listed as BACnet Application Specific
Controllers (B-ASCs). FAC field controllers and the
VMA1930 Field Controller are BTL-listed as BACnet
Advanced Application Controllers (B-AACs).
Release 10.1 and later of the Controller
Configuration Tool (CCT) can be used to switch the
Field Bus communications protocol in supported
FAC, FEC, and VMA controllers to be either the
standard BACnet MS/TP or the N2 protocol. All new
controllers use either BACnet MS/TP as the default
communications protocol, or BACnet/IP. Switchable
communications protocols in the MS/TP models
provide a cost-effective upgrade and modernization
path for customers with existing N2 controllers.
The Modernization Guide for Legacy N2 Controllers
(LIT-12012005) and the controller-specific
documentation provide installation and
commissioning support and include tips for
efficient and safe replacement. Refer to the N2
Compatibility Options chapter of the Controller
Tool Help (LIT-12011147) for information about
mapping N2 Objects in controllers with switchable
communications protocols.
The N2-capable FEC Family Controllers can be used
as functional replacements for legacy N2 controllers.
The N2-capable FEC Family Controllers:
• have the input and output (I/O) quantities and
characteristics of the FEC Family Controllers
• must be programmed with CCT, which has similar,
but not identical programming capabilities as
HVACPro, GX9100, GPL, and other legacy tools
• support SA Bus devices
• support WRZ wireless sensors from the controller
using the WRZ-7860 receiver (most models)
• are available in Buy American versions (most
models)
• are listed for UL 864 UUKL/ORD-C100-13 UUKLC
10th Edition Smoke Control (some models).
N2 is now supported as part of the Metasys®
10th Edition listing for Smoke Control System
Equipment.
The N2-capable FEC family controllers:
• do not support Zone Bus (for example, TMZ
sensors and M100 actuators) or XT-Bus (System
91) devices (for example, XT, XTM, and XP
modules)
• do not support a wireless connection to the N2
bus
• do not support NxE passthrough

For detailed information on configuring and
wiring an MS/TP Bus, FC bus, and SA bus, refer to
the MS/TP Communications Bus Technical Bulletin
(LIT-12011034).
FAC terminal blocks and bus ports
See FAC2612-2 physical featuresfor terminal block
and bus port locations on the FAC2612-2 controller.
Observe the following guidelines when wiring a
controller:
Input and output Terminal Blocks
Most of the input terminal blocks are mounted on
the bottom of the controller and the output terminal
blocks are mounted on the top of the controller.
See Table 2 for more information about I/O terminal
functions, requirements, and ratings.
FAC2612-2 Advanced Application Field Equipment Controller Installation Guide 5

FC Bus Terminal Block
The FC Bus terminal block is a blue, removable, 4-
terminal plug that fits into a board-mounted jack.
Wire the removable FC bus terminal block plugs on
the controller, and other controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 4 for more information.
Figure 4: FC Bus Terminal Block Wiring
Note: The FC bus Shield (SHLD) terminal is
isolated and can be used to connect (daisy
chain) the shields for FC bus wiring.
SA Bus Terminal Block
The SA Bus terminal block is a brown, removable, 4-
terminal plug that fits into a board-mounted jack.
Wire the removable SA Bus terminal block plugs on
the controller, and other SA bus devices in a daisy-
chain configuration using 4-wire twisted, shielded
cable as shown in Figure 5 for more information.
Figure 5: SA Bus Terminal Block Wiring
Note: The SA PWR terminal supplies 15 VDC.
The SA PWR terminal can be used to connect
(daisy chain) the 15 VDC power leads on the SA
bus.
FC Bus Port
The FC bus port on the front of the controller is an
RJ-12, 6-pin modular jack that provides a connection
for the Wireless Commissioning Converter, ZFR181x
Wireless Field Bus Router, or ZFR182x Wireless Field
Bus Router.
The FC bus port is connected internally to the FC bus
terminal block. See Table 4.
Note: When the FAC is configured for N2
network communication, the FC bus port
cannot be used.
Figure 6: Pin Number Assignments for Sensor, SA
Bus, and FC Bus Ports on Controllers
FAC2612-2 Advanced Application Field Equipment Controller Installation Guide6

SA Bus Port
The Sensor (SA Bus) port on the bottom of the
controller is an RJ-12, 6-position modular jack
that provides a connection for the Wireless
Commissioning Converter, the VAV Balancing Tool,
specified network sensors, or other SA Bus devices
with RJ-12 plugs. When the FEC is configured for N2
network communication, the SA Bus port must be
used to download and commission the controller.
A DIS1710 Local Controller Display also can be
connected to the SA Bus port.
The Sensor port is connected internally to the SA
bus terminal block.
Supply Power Terminal Block
The 100-240 VAC supply power terminal block is
a gray, removable, 3-terminal plug that fits into
a board-mounted jack on the top right of the
controller.
Wire the 100–240 VAC supply power wires from the
transformer to the HOT and COM terminals on the
terminal plug as shown in the following figure:
Figure 7: 100-240 VAC Supply Power Terminal
Block Wiring
Note: The supply power wire colors may
be different on transformers from other
manufacturers. Refer to the transformer
manufacturer’s instructions and the project
installation drawings for wiring details.
Important: Connect 100–240 VAC supply
power to the controller and all other network
devices so that transformer phasing is uniform
across the network devices. Powering network
devices with uniform 100–240 VAC supply
power phasing reduces noise, interference, and
ground loop problems. The controller does not
require an earth ground connection.
Wireless network applications
When configured for BACnet MS/TP communication,
the controller can also be installed in a wireless
application using a ZFR181x or ZFR182x Wireless
Field Bus Router. To configure a controller for use
with the WNC1800/ZFR182x Pro (ZFR Pro) Series
Wireless Field Bus system:
1. Wire the input/output terminals and SA bus.
Note: In wireless network applications, do not
connect any wires to the FC bus terminal block.
(Connect the SA/FC terminal block on an IOM
to an SA bus only.)
2. Connect the ZFR181x or ZFR182x Wireless Field
Bus Router to the FC bus port (RJ-12 modular
jack) on the front of the field controller.
3. Ensure that the controller's device address DIP
switches are set to the correct device address.
See Setting the device address.
4. Set DIP switch 128 to ON, which enables
wireless operation on the field controller.

Setup and Adjustments
Setting the device address
Metasys field controllers are master devices on an
MS/TP (SA or FC) bus. Before you operate field
controllers on a bus, you must set a valid and
unique device address for each controller on the
bus. You set a field controller's device address by
setting the positions of the switches on the DIP
switch block at the top of the controller. Device
addresses 4 through 127 are the valid addresses for
these controllers on an MS/TP FC Bus.
The DIP switch block has eight switches numbered
128, 64, 32, 16, 8, 4, 2, and 1. Switches 64 through 1
are device address switches. Switch 128 must be set
to OFF for all hard-wired SA and FC bus applications.
Figure 9: Device address DIP switch block set to
address 21
Note: Metasys field controllers ship with switch
128 ON and the remainining adress switches
off rendering the controllers wired subordinate
devices, which do not operate on MS/TP
buses, but do not interfere with bus operation.
Set a valid and unique device address on
the controller before applying power to the
controller on the bus.
To set the device addresses on the controllers,
complete the following steps:
1. Set all of the switches on the address DIP
switch block (128 through 1) to OFF.
2. Set one or more of the seven address switches
(64 though 1) to ON, so that the sum of the
switch numbers set to ON equals the intended
device address. Set the highest number switch
that is less than or equal to the intended device
address to ON. Then continue setting lower
numbered switches until the total equals the
intended address. For example, if the intended
device address is 21, set switch 16 to ON first,
then set switch 4 ON, followed by switch 1
(16+4+1= 21). See Figure 9.See for valid device
addresses.
3. Set switch 128 to ON only for controllers on an
WNC1800/ZFR182x Pro (ZFR Pro) Series Wireless
Field Bus application. For all hard-wired SA and
FC bus applications, ensure that switch 128 is
set to Off
Note: Do not connect an controller with switch
128set to ON to anactive (hard-wired) SA or
FC bus. When a controller with switch 128 set
to ON and a device address from 4 to 127 is
connected to a wired field bus, the entire field
bus is rendered inoperable until the controller
is disconnected or switch 128 is set to Off.
Refer to the WNC1800/ZFR182x Pro Series Wireless
Field Bus System Technical Bulletin (LIT-12012356) for
more information on device addresses in wireless
applications
4. Set a unique and sequential device address for
each of the controllers connected on the SA or
FC bus starting with device address 4. To ensure
the best bus performance, set sequential device
addresses with no gaps in the device address
range (4, 5, 6, 7, 8, 9, and so on). The controllers
do not need to be physically connected on the
bus in their numerical device address order.
5. Write each controller's device address on the
white label below the DIP switch block on the
controller's cover.
The following table describes the FC bus and SA bus
devices addresses for controllers communications
bus applications.
Refer to the MS/TP Communications Bus Technical Bul-
letin (LIT-12011034) for more information on con-
troller device addresses and how to set them on
MS/TP buses.

Valid for MS/TP Master controllers on wireless FC
Buses only.
Note: Do not connect a controller with switch
128 ON to an active (hard-wired) SA or
FC bus. When a controller with switch 128
ON and a device address from 4 to 127 is
connected to a wired field bus, the entire
field bus is rendered inoperable until the
controller is disconnected or switch 128 is set
to Off.
Setting the N2 Controller address to
be greater than 127
N2-configured controllers support the full range
of possible N2 device addresses provided by the
N2 protocol standard (1–254). However, these
controllers require special configuration for
addresses above 127.
Use the following instructions for controllers greater
than 127.
Note: This special configuration is required
because controller addresses above 127 were
originally intended for use with the Wireless
Field Bus system.
Note: Prior to performing this procedure,
be sure the controller has been converted
from BACnet to N2 protocol first. Refer to the
Modernization Guide for Legacy N2 Controllers
(LIT-12012005) for more information.
1. Disconnect the 24 VAC supply from the
controller.
2. Remove the FC Bus connector from the
controller.
3. Set the address switch set to the desired N2
address.
4. Set the address switch segment labeled 128 to
OFF.
5. Reconnect the 24 VAC supply to the controller.
6. Using an SA bus connection, download the
firmware and controller application file. The
download process asks to confirm switching the
communication protocol to N2.
7. Click OK.
8. After the download is finished, disconnect the
24 VAC supply to the controller.
9. Set the address switch segment labeled 128 to
ON.
10. Reattach the FC Bus connector to the controller.
11. Reconnect the 24 VAC supply to the controller.
Setting the End-of-Line (EOL) switch
Each field controller has an EOL switch, which, when
set to ON, sets the controller as a terminating device
on the bus. The default EOL switch position is OFF.
Figure 10: End-of-Line switch positions
To set the EOL switch on a field controller, complete
the following steps:
1. Determine the physical location of the field
controller on the FC bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note: For detailed information regarding EOL
termination rules and EOL switch settings on
FC buses, refer to the MS/TP Communications
Bus Technical Bulletin (LIT-12011034).
FAC2612-2 Advanced Application Field Equipment Controller Installation Guide 17

3. If the controller is a terminating device on
the FC bus, set the EOL switch to ON. If the
controller is not a terminating device on the
bus, set the EOL switch to Off.
When a controller is connected to power with its
EOL switch set to ON, the amber EOL LED on the
controller cover is lit.
Setting the UI current loop DIP
switches
The five Universal Input (UI) current loop switches
are on the (6-switch) DIP switch block on the
controller cover near the UI terminals (see
FAC2612-2 physical features). When a UI is defined
in the system software as a 4–20 mA Analog Input
(AI) and the UI’s current loop switch is in the
DISABLED (default/off/down) position, the 4–20
mA current loop circuit opens whenever power
to the field controller is interrupted or off. Setting
a current loop switch to the ENABLED (ON/up)
position maintains the 4–20 mA current loop
circuit even when power to the field controller is
interrupted or off.
Figure 11: Current loop jumper positions
To set the current Loop Mode switches:
1. Determine if the UI is intended to operate as a
4–20 mA AI (and configure the system software
accordingly).
2. If the UI is not intended to be a 4–20 mA AI,
set the UI’s corresponding Current Loop Mode
switch to the off/ down position.
3. If the UI is intended to be a 4–20 mA AI and
the current loop is intended to be maintained,
set the UI’s corresponding Current Loop Mode
switch to the ON/up position.
Important: Current Loop switches must be
in the DISABLED (off/down) position for all
UIs that are not set up to operate as 4–20 mA
analog inputs.
