MS-FAC2611-0U

Part No. 24-10143-01620, Rev. —

Software Release 8.1

Issued March 2018

Application

The FAC2611 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 and provide the inputs and outputs required

to monitor and control a wide variety of HVAC equipment.

FAC26 field controllers operate on an RS-485 BACnet®

MS/TP Bus as BACnet Advanced Application Controllers

(B-AACs) and integrate into Johnson Controls®and

third-party BACnet systems.

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 system network.

Important: The MS-FAC2611-0U model is used in

Metasys Release 8.1 smoke control

applications and is UL 864 UUKL/UUKLC

10th Edition Smoke Control Listed. You

must refer to the Metasys®System UL 864

10th Edition UUKL/ORD-C100-13 UUKLC

Smoke Control System Technical Bulletin

(LIT-12012487) for detailed requirements

and procedures for installing,

commissioning, and operating UL 864

UUKL/UUKLC Listed Metasys system

devices. The UL 864 UUKL/UUKLC listing

for Smoke Control Equipment is voided if

(1) you do not use the required software

tools at the required versions; or (2) you do

not meet the requirements or do not follow

the procedures as documented in the

Metasys®System UL 864 10th Edition

UUKL/ORD-C100-13 UUKLC Smoke

Control System Technical Bulletin

(LIT-12012487).

Switchable Communications

Protocols

The Family Controllers and network sensors communicate

using the standard BACnet protocol, based on the

ANSI/ASHRAE 135-2004. The BACnet protocol is a

standard for ANSI, ASHRAE, and the International

Standards Organization (ISO) for building controls.

Most FEC, VMA16, VMA18,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).

You can use Release 10.3 and Release Module (RM)

10.2 of the Controller Configuration Tool (CCT) to switch

the Field Bus communications protocol in supported FEC,

FAC and VMA controllers to be either the standard

BACnet MSTP or the N2 protocol. All new controllers use

BACnet MSTP as the default communications protocol.

Switchable communications protocols in the MSTP

models provide a cost-effective upgrade and

modernization path for customers with existing N2

controllers.

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

•are available in Buy American versions (most models)

• are listed for UL864 UUKL/UUKLC (some models).

N2 is supported as part of the Metasys®10th Edition

listing for Smoke Control System Equipment.

1FAC2611-0U Advanced Application Field Equipment Controller Installation Instructions

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

communication, the FC bus port is not used.

Figure 6: Pin Number Assignments for Sensor, SA

Bus, and FC Bus Ports on Field Controllers

Sensor 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 VAV Balancing Tool, specified network

sensors, or other SA Bus devices with RJ-12 plugs.

The Sensor port is connected internally to the SA bus

terminal block. See Comm Bus and Power Supply

Terminal Block Rating and Requirements Table for more

information. The Sensor Port pin assignment is shown

in Figure 6.

Supply Power Terminal Block

The 24 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.
