Johnson Controls FAC2612-1 Installation Manual

Application
The FAC2612-1 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) 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.
FAC2612-1 Advanced Application Field
Equipment Controller Installation Guide
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
