FAC4911 Advanced Application Field Equipment
Application
The FAC4911 Advanced Application Field Equipment
Controller is part of the Metasys® system Field
EquipmentController family. The FAC4911
equipment controllers run pre-engineered and userprogrammed applications, and provide the inputs
and outputs required to monitor and control a wide
variety of HVAC equipment.
FAC4911 controllers operate on BACnet®/IP
networks and integrate into Johnson Controls
and third-party systems. The 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 Metasys system FAC family controllers and
network sensors communicate using the BACnet
protocol. The BACnet protocol is a standard for
ANSI, ASHRAE, and the International Standards
Organization (ISO) for building controls. FAC
equipment controllers are BTL-listed and certified as
BACnet Advanced Application Controllers (B-AACs).

Mounting
Observe the following guidelines when mounting a
field controller:
• Ensure the mounting surface can support the
controller, DIN rail, and any user-supplied
enclosure.
• Mount the controller horizontally on 35 mm DIN
rail whenever possible.
• Mount the controller in the correct mounting
position (Figure 2).
• Whenever possible in wall-mount applications,
mount the controller on a hard, even surface.
• Use shims or washers to mount the controller
securely and evenly on the mounting surface.
• Mount the controller in an area free of corrosive
vapors and observe the ambient conditions
requirements in Technical specifications.
• Provide sufficient space around the controller for
cable and wire connections, easy cover removal,
and good ventilation through the controller (50
mm [2 in.] minimum on the top, bottom, and
front of the controller).
• Do not mount the controller on surfaces prone to
vibration, such as ductwork.
• Do not mount the controller in areas where
electromagnetic emissions from other
devices or wiring can interfere with controller
communication.
Observe these additional guidelines when mounting
a field controller in a panel or enclosure:
• Mount the controller so that the enclosure walls
do not obstruct cover removal or ventilation
through the controller.
• Mount the controller so that the power
transformer and other devices do not radiate
excessive heat to the controller.
• Do not install the controller in an airtight
enclosure.

Wall mount applications
To mount a field controller directly on a wall or
other flat vertical surface, complete the following
steps:
1. Pull the two bottom mounting clips outward
and ensure they are locked in the extended
position.
2. Mark the mounting hole locations on the wall
in either the horizontal or vertical mounting
position. Or hold the controller up to the wall or
surface in a proper mount position and msark
the hole locations through the mounting clips.
3. Drill holes in the wall or surface at the marked
locations, and insert appropriate wall anchors
in the holes (if necessary).
4. Hold the controller in place, and insert the
screws through the mounting clips and into the
holes (or anchors). Carefully tighten all of the
screws.
DIN Rail mount applications
Mounting the field controller horizontally on 35 mm
DIN rail is the preferred mounting method.
To mount a field controller on 35 mm DIN rail,
complete the following steps:
1. Securely mount a 23 cm (9.125 in.) or longer
section of 35 mm DIN rail, horizontally and
centered in the desired space, so that the
controller mounts in the position shown in
Figure 2.
FAC4911 Advanced Application Field Equipment Controller Installation Guide4
Important: Do not overtighten the mounting
screws. Overtightening the screws may
damage the mounting clips.
Wiring
CAUTION
Important: Electrostatic discharge can
damage controller components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid
damaging the controller.
Risk of Electric Shock:
Disconnect the power supply before making electrical
connections to avoid electric shock
ATTENTION
Mise En Garde: Risque de décharge électrique
Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de
décharge électrique.
CAUTION
Risk of Property Damage:
Do not apply power to the system before checking all
wiring connections. Short circuited or improperly connected wires may result in permanent damage to the
equipment.
ATTENTION
Mise En Garde: Risque de dégâts matériels
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement
l'équipement.
For detailed information about configuring and
wiring an MS/TP bus, FC bus and SA bus, refer to
the MS/TP Communications Bus Technical Bulletin
(LIT-12011034).
Network topology
FAC4911 controllers may be connected to a building
automation network in multiple ways: as daisychained devices, as part of a star (also called home
run) network, or as part of a ring network.
To daisy-chain FAC4911 controllers, connect the
controllers to the bus supervisor in a chain with
the Ethernet cable connecting to the FAC4911
at the ETH1 or ETH2 port and connecting to the
next device from the other port. Benefits of daisychained networks are that they require less physical
wiring and new devices can be added easily to the
network.
In a star network, each FAC4911 controller is
connected directly back to a main switch. This
configuration reduces the possibility of network
failure but requires more wiring to install.
A ring network is a chain of controllers virtually
closed by a software component in an Ethernet
switch. Not all switches support the ring topology.
The dual-port controller from Johnson Controls
supports Media Redundancy Protocol (MRP). MRP
allows a chain of Ethernet devices to overcome any
single communication failure, with a recovery time
faster than in a BACnet system.
For more information about network topologies
for the BACnet/IP Controllers, refer to the Metasys
IP Networks for BACnet/IP Controllers Configuration
Guide Technical Bulletin (LIT-12012458).
Important: Do not exceed the controller
electrical ratings. Exceeding controller electrical
ratings can result in permanent damage to the
controller and void any warranty.
Important: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
FAC4911 Advanced Application Field Equipment Controller Installation Guide 5
Terminal blocks and bus ports
See for terminal block and bus port locations on the
controller. Observe the following guidelines when
wiring a controller.
Input and Output terminal blocks
The fixed input terminal blocks are located on the
bottom of the controller, and the output terminal
blocks are located on the top of the controller. See
Table for more information about I/O terminal
functions, requirements, and ratings.
SA bus terminal block
The SA Bus terminal block is a brown, removable, 4terminal 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 daisychain configuration using 4-wire twisted, shielded
cable as shown in Figure 4. For more information
about the SA Bus terminal function, requirements,
and ratings, see .
Figure 4: SA bus terminal block wiring
Wire the 24 VAC supply power wires from the
transformer to the HOT and COM terminals on the
terminal plug as shown in Figure 5. Do not use the
middle terminal on the supply power terminal block.
See for more information about the Supply Power
Terminal Block.
Figure 5: 24 VAC supply power 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.
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 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a boardmounted jack on the top right of the controller.
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 24 VAC supply power
to the field controller and all other network
devices so that transformer phasing is uniform
across the network devices. Powering network
devices with uniform 24 VAC supply power
phasing reduces noise, interference, and
ground loop problems. The field controller
does not require an earth ground connection.
Terminal Wiring Guidelines, Functions, Ratings, and Requirements
Input and output wiring guidelines
The following table provides information and
guidelines about the functions, ratings, and
requirements for the controller input and
output terminals; and references guidelines for
determining proper wire sizes and cable lengths.
FAC4911 Advanced Application Field Equipment Controller Installation Guide6
In addition to the wiring guidelines in the following
table, observe these guidelines when wiring
controller inputs and outputs:
• Run all low-voltage wiring and cables separate
from high-voltage wiring.
• All input and output cables, regardless of wire
size or number of wires, should consist of
stranded, insulated, and twisted copper wires.
• Shielded cable is not required for input or output
cables.
• Shielded cable is required for input and output
cables that are exposed to high electromagnetic
or radio frequency noise.
• Inputs or outputs with cables less than 30 m
(100 ft) typically do not require an offset in the
software setup. Cable runs over 30 m (100 ft) may
require an offset in the input/output software
setup.

Setup and Adjustments
Setting the Controller Number
Each controller on a network must have a unique
number on the subnet where it resides in order to
identify it in the Controller Configuration Tool (CCT)
for uploading, downloading, and commissioning.
The controller number is set using three rotary
switches (Figure 7) and may be numbered from 000
to 999. The numbers are ordered from left to right,
most significant bit (MSB) to least significant bit
(LSB) when the controller is oriented as shown in
FAC4911 physical features.
In the following figure the switches are set to
4 2 5, designating this controller as controller
number 425. The controller number must match
the controller number defined in CCT under Define
Hardware > Network Settings. The number of
the controller can be written in the white squares
provided so the controller number can be easily
seen from a distance.
Figure 7: Rotary Switch for Setting Controller
Numbers
Note: The BACnet device ID is calculated
using the value of controller number added
to 2000000 . The device ID configured in this
manner does not require any configuration
from CCT.
FAC4911 Advanced Application Field Equipment Controller Installation Guide 17

The controller cover is held in place by four
plastic latches that extend from the base and
snap into slots on the inside of the housing
cover.
To remove the controller cover, complete the
following steps:
1. Place your fingertips under the two cover lift
tabs on the sides of the housing cover and
gently pry the top of the cover away from the
base to release the cover from the two upper
latches.
2. Pivot the top of the cover further to release it
from the lower two latches.
3. Replace the cover by placing it squarely over
the base, and then gently and evenly push the
cover on to the latches until they snap into the
latched position.
Setting the Input Jumpers
Figure 8: Current loop jumper positions
Set the current loop jumper to the Enabled position
(Figure 8) to connect an internal 100 ohms resistor
across the UI terminals, which maintains the 4–20
mA current loop circuit even when power to the
controller is interrupted or off.
Important: Current loop jumpers must be in
the Disabled (default) position for all UIs that
are not set up to operate as 4–20 mA analog
inputs.
The following table identifies the current loop
switches associated with each UI on the controller.
Table 7: UI Inputs and Jumper Labels
CAUTION
Risk of Electric Shock:
Disconnect supply power to the field controller before
attempting to adjust the Binary Output Source Power
Selection Jumpers. Failure to disconnect the supply
power may result in electric shock.

Input/Output Wiring Validation
Commissioning Field controllers
The FAC4911 controllers ship with a default state
that can assist in validating the wiring of the input
and output terminals prior to download of an
application file. When the controller is powered on
in this state, the Fault LED will flash in a pattern of
two quick blinks and then a long pause (see Table
8).
To make use of this feature, ensure the rotary
switches are set to the desired controller number
and wire the input and output terminals. Apply
power to the FAC controller and connect to the
device with either a MAP Gateway or MS-DIS1710-0
Local Display to view the points in the controller.
The FAC controller will report an Operational status
even though there is no true application loaded.
CCT will not be able to commission or upload
the device as a result until a true application is
downloaded. The application name displayed will be
the controller number followed by the model of the
controller and “Default State”.
For example, a FAC4911 controller whose rotary
switches are set to 8 would have the default state
application name of “8-FAC4911 Default State”.
The default state creates I/O points for all
connections on the input and output terminals.
It assumes all Universal Inputs (UIs) are Nickel
temperature sensors. All Configurable Outputs
(COs) are treated as Binary Outputs (BOs) with an
initial value of 0. The default state also takes input
from a Network Sensor at address 199. If there is
no connected Network Sensor, the startup of this
default state will be delayed by 30 seconds as the
controller attempts to establish connection with the
sensor.
You commission controllers with the CCT software,
either via a Bluetooth® Wireless Commissioning
Converter, a ZFR wireless dongle, MAP 4.2+/ BACnet
Router (Mobile Access Portal (MAP) Gateway at
version 4.2 or above), or in passthrough mode when
connected to an NAE or NCE. Refer to Controller
Tool Help (LIT-12011147) for detailed information on
commissioning field controllers.
Note: The MAP Gateway serves as a
replacement for the BTCVT, which is no longer
available for purchase, but continues to be
supported.
Firmware Package File
The MS-FCP-0 equipment controller firmware
package files are required for CCT to configure and
commission the controllers. The firmware package
files also allow you to upgrade an existing controller
to the latest firmware release available for that
controller.
Beginning at CCT Release 13, the firmware package
files are orderable separately; they are not included
with CCT. They are obtained from the Metasys
software licensing portal, and are loaded and
licensed on the computer/server that is running
CCT.
For additional information about the firmware
package files, refer to the CCT Installation Instructions
(LIT-12011259).
Troubleshooting Field Controllers
Observe the Status LEDs on the front of the field
controller and see the table below to troubleshoot
the controller. To troubleshoot an integral or
local controller display, refer to the DIS1710 Local
Controller Display Technical Bulletin (LIT-12011270).
