Johnson Controls Metasys FAC4911 - User Manual

FAC4911 Advanced Application Field Equipment
Controller Installation Guide
Application
The FAC4911 Advanced Application Field Equipment
Controller is part of the Metasys
®
system Field
EquipmentController 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
®
/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).

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.
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.
Installation
Observe the following guidelines when installing a
field controller:
• To minimize vibration and shock damage,
transport the controller in the original container.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
Parts included
• One field Controller. (Power and SA bus terminal
blocks are removable)
• One installation instructions sheet.
Materials and special tools needed
• Three fasteners appropriate for the mounting
surface (M4 screws or #8 screws)
• One 23 cm (9.125 in.) or longer piece of 35 mm
DIN rail and appropriate hardware for DIN rail
mount (only)
• Small straight-blade screwdriver for securing
wires in the terminal blocks
