FEC26 Field Equipment Controllers Installation Instructions
MS-FEC2611-x, MS-FEC2621-x, MS-FEC2611-x OET,
Application
The FEC26 controllers are part of the Metasys® system
Field Equipment Controller (FEC) family. The FEC2511
is a modification of the FEC26 controllers. These
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.
The FEC controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls® and third-party BACnet systems.
The FEC26 controller is available with or without an
integral LCD and push button user interface.
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
135-2004.
The BACnet protocol is a standard for ANSI, ASHRAE,
and the International Standards Organization (ISO) for
building controls.
FEC, IOM, and VMA16 controllers are BTL- tested and
listed as BACnet Application Specific Controllers
(B-ASCs). FAC field controllers 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 of CCT and later can be used to switch the
Field Bus communications protocol in FEC Family Field
Controllers to be either the standard BACnet
Master-Slave/Token-Passing (MS/TP) or the N2 protocol.
BACnet MS/TP is the default communications protocol
for all new controllers. Switchable communications
protocols 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 Compatibility Options
chapter of the Controller Tool Help (LIT-12011147) for
information about mapping N2 Objects in controllers with
switchable communications protocols.
FEC26Field Equipment Controllers Installation Instructions
Part No. 24-10143-144, Rev. K
Refer to the
QuickLIT website
The N2-capable FEC family controllers can be used as
functional replacements for legacy N2 controllers. The
N2-capable FEC family controllers:
•
have the 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
•
are available in Buy American versions (most models)
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 pass through
•
are not listed for UL864 UUKL. N2 is not supported
as part of the Metasys® 9th Edition listing for Smoke
Control System Equipment
North American Emissions
Compliance
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.
