Johnson Controls FAC2611 - User Manual

FAC2611 Advanced Application Field Equipment
Controller Installation Guide
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.
Switchable communications protocols
By default, the Metasys system FEC Family Controllers
and network sensors communicate using the standard
BACnet protocol based on the ANSI/ASHRAE 135-2008. The
BACnet protocol is a standard for ANSI, ASHRAE, and the
International Standards Organization (ISO) for building
controls.
FEC, VMA16, and VMA18 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). The NS Series Sensors are BTL-listed as BACnet
Smart Sensors (B-SSs).
Release 10.1 and later of the Controller Configuration Tool
(CCT) can be used to switch the Field Bus communications
protocol in supported FEC Family Field Controllers to be
either the standard BACnet MS/TP or the N2 protocol.
All new controllers use BACnet MS/TP as the default
communications protocol. Switchable communications
protocols in the MS/TP 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
• 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. For details, refer
to the Metasys System UL 864 10th Edition UUKL/ORD-
C100-13 UUKLC Smoke Control System Technical Bulletin
(LIT-12012487).
The N2-capable 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
North American emissions compliance
United States
This equipment has been tested and found to comply with
the limits for a Class A digital device pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
this equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area may cause harmful
interference, in which case the users will be required to
correct the interference at their own expense.
Canada
This Class (A) digital apparatus meets all the requirements
of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur du
Canada.
Installation
Observe these guidelines when installing a field controller:
• Transport the controller in the original container to
minimize vibration and shock damage.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
Parts included
• One field controller with removable terminal blocks
(Power, SA, and FC bus are removable)
• One installation instructions sheet
