FAC3613 Advanced Application Field Equipment
Controller Installation Guide
Application
The FAC3613 Advanced Application Field Equipment
Controller (FAC) is part of the
Metasys
®
system
Field Equipment Controller family. The FAC36
Series controllers run pre-engineered and user-
programmed applications and provides the inputs
and outputs required to monitor and control a wide
variety of HVAC and other facility equipment.
FAC36 controllers operate on an RS-485 BACnet
®
MS/TP Bus as BACnet Advanced Application
Controllers (B-AACs) and integrate into Johnson
Controls
®
and third-party BACnet systems.
FAC36 field 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.
Communications protocols
The FAC3613 field controllers can communicate
using BACnet MS/TP, N2, or wireless Zigbee. By
default, the FAC3613 field controllers communicate
using the standard BACnet MS/TP protocol. The
BACnet protocol is a standard for ANSI, ASHRAE, and
the International Standards Organization (ISO) for
building controls.
The FEC Family Controllers, including the FAC3613,
can be used as functional replacements for
legacy N2 controllers. The N2-capable MS/TP
field controller models provide a cost-effective
upgrade and modernization path for customers
with existing N2 controllers. For installation and
commissioning support, and tips for efficient and
safe replacement, refer to the
Modernization Guide
for Legacy N2 Controllers (LIT-12012005)
and the
controller-specific documentation. For information
about mapping N2 Objects in controllers with
switchable communications protocols, refer to the
N2 Compatibility Options
chapter of the
Controller Tool
Help
(LIT-12011147).
To configure FAC3613 field controllers to
communicate using the N2 communications
The FAC3613 field controller can also be installed in
a wireless application using a ZFR/ZFR Pro Wireless
Field Bus Router. To configure these controllers to

Fast persistence
The FAC3613 model has been significantly upgraded
and now includes a fast persistence feature that
allows you to retain data values at a configurable
interval, up to once per second. Persistence refers
to how often samples of data are stored locally. This
upgrade to the persistence feature ensures that
in the event of a problem, such as a loss of power,
more recent data can be retrieved up to the rate that
the data is persisted, minimizing the potential loss of
data. When power is restored, previously persisted
data, up to the rate of persistence, is still available
and accessible. When persistence is configured
for once per second, you risk losing only the most
recent one second of data before the power loss.
Persisting data may be essential for situations that
require greater data accuracy. This may include
certain methods of utility data collection and billing
Attributes that can be persisted in the FAC3613
include: Counter Input Present Value Attributes,
Binary Input, Binary Output, and Binary Value COS
Counts and Active Time Attributes, and PID/PRAC
tuning parameters.

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.
