Application
The FAC4911 Advanced Application Field Equipment
Controller is part of the Metasys system Field Equipment
Controller family. The FAC4911 equipment 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.
FAC4911 controllers operate on BACnet
(BACnet/SC) or BACnet/IP networks and integrate
into Johnson Controls
and third-party systems. The
®
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
Metasys system network.
The Metasys system FAC family controllers and network
sensors communicate using the BACnet protocol. The
BACnet protocol is a standard for ANSI, ASHRAE, and the
International Standards Organization (ISO) for building
controls. FAC equipment controllers are BTL-listed and
certified as BACnet Advanced Application Controllers (B-
AACs).
North American emissions compliance
United States
This equipment has been tested and found to comply with
the limits for a Class A digital device pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
this equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area may cause harmful
interference, in which case the users will be required to
correct the interference at their own expense.
Warning (Part 15.21)
Changes or modifications not expressly approved by the
party responsible for compliance could void the user's
authority to operate the equipment.
Canada
This Class (A) digital apparatus meets all the requirements
of the Canadian Interference-Causing Equipment
Regulations.
