FEC1611 and FEC1621 Field Equipment Controller
Installation Instructions
MS-FEC1611-1U, MS-FEC1621-1U
Application
The FEC16 Field Equipment Controller (FEC) is part of the Metasys® system Field Equipment Controller family.
The FEC16 controller runs pre-engineered and user-programmed applications and provides the inputs and outputs
required to monitor and control a wide variety of HVAC equipment.
The FEC controllers can communicate using either BACnet MS/TP or N2 communications protocols. These controllers
used as MS/TP devices operate on an RS-485 BACnet® MS/TP Bus as BACnet Application Specific Controllers
(B-ASC) and integrate into Johnson Controls® and third-party BACnet systems.
The FEC16 controller is available with or without an integral LCD and push-button user interface.
Important: The MS-FEC1611-1U and MS-FEC1621-1U models are used in Metasys Release 8.1 smoke control
applications and are UL 864 UUKL/UUKLC 10th Edition Smoke Control Listed. You must refer to the
Metasys® System UL 864 10th Edition UUKL/ORD-C100-13 UUKLC Smoke Control System Technical
Bulletin (LIT-12012487) for detailed requirements and procedures for installing, commissioning, and
operating UL 864 UUKL/UUKLC listed Metasys system devices. The UL 864 UUKL/UUKLC 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 10th Edition UUKL/ORD-C100-13 UUKLC Smoke Control System
Technical Bulletin (LIT-12012487).
Communications Protocol
The Metasys® system FEC Family controllers and network sensors communicate using either the standard BACnet
protocol, based on the ANSI/ASHRAE 135-2004, or the BACnet/IP protocol. The BACnet protocol is a standard for
ANSI, ASHRAE, and the International Standards Organization (ISO) for building controls.
Most FEC, VMA16, VMA18, and 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 10.3 with Release Module (RM) 10.2 of the Controller Configuration Tool (CCT) can be used to switch the
Field Bus communications protocol in supported FEC, FAC and VMA controllers to be either the standard BACnet
MSTP or the N2 protocol. All new controllers use BACnet MSTP as the default communications protocol. Switchable
communications protocols in the MSTP 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, which has similar, but not identical programming capabilities as HVACPro,
GX9100, GPL, and other legacy tools
•
support SA Bus devices
•
are available in Buy American versions (most models)
•
are listed for UL864 UUKL/UUKLC (some models). N2 is 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).
