Johnson Controls FAC2612-2 Installation Manual

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
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
FAC2612-2 Advanced Application Field
Equipment Controller Installation Guide
system.

Tool Help (LIT-12011147) for information about

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
