Application
The FEC26 controllers are part of the Metasys® system
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®
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.
Important: In Metasys system smoke control
applications, use only the MS-FEC2611-0U and MS-FEC2621-0U at Metasys Release
8.1 that are 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 either the standard BACnet protocol based on the ANSI/ASHRAE 135-2004, or the BACnet/IP protocol.
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). 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, 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 UL864 UUKL/UUKLC (some models).
N2 is supported as part of the Metasys® Tenth 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
The BACnet protocol is a standard for ANSI, ASHRAE, and the International Standards Organization (ISO) for building controls.
