Application
The FEC26 controllers are part of the Metasys
Field Equipment Controller (FEC) family. 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 and other facility
equipment.
The FEC controllers operate on an RS-485 BACnet
TP Bus as BACnet Application Specific Controllers (B-ASCs)
and integrate into Johnson Controls
BACnet systems.
The FEC26 controller is available with or without an
integral LCD and push button user interface.
Important: In Metasys system smoke control
applications, use only the MS-FEC2611-0U and MS-
FEC2621-0U at Metasys Release 8.1 that is UL 864
UUKL/UUKLC 10th Edition Smoke Control Listed. For
Metasys system smoke control applications, you must
refer to the Metasys System UL 864 UUKL Tenth Edition
Smoke Control System Technical Bulletin (LIT-12012487)
for detailed requirements and procedures for
installing, commissioning, and operating UL 864
UUKL Listed Metasys system devices. The UL 864
UUKL 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 UUKL
Tenth Edition Smoke Control System Technical Bulletin
(LIT-12012487).
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
