IOM4711 Input/Output Module Installation Instructions
MS-IOM4711-0U
Application
The IOM47 field controller is part of the Metasys® system
Field Equipment Controller family. Input/Output Module
(IOM) controller expand the number of points connected
to a Network Automation Engine (NAE), Field Equipment
Controller (FEC), or Advanced Application Field
Equipment Controller (FAC) to monitor and control a wide
variety of HVAC equipment.
IOM controllers operate on an RS-485 BACnet® MS/TP
Bus as BACnet Application Specific Controllers (B-ASCs)
and integrate into Johnson Controls® and third-party
BACnet systems.
Note: With CCT Release 10.3 and Release Module (RM)
10.2, a new capability allows VMAs, FECs, and
FACs to communicate by using either the BACnet
or the N2 field bus networking protocol. The I/O
can be connected through the SA bus to a host
controller that is using either the BACnet or the
N2 protocol. Only the BACnet protocol is
supported when the I/O is connected directly to
the trunk using the FC bus.
Important: The MS-IOM4711-0U model is used in
Metasys Release 8.1 smoke control
applications and is 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).

North American Emissions
Compliance
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.
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.
Installation
Observe these guidelines when installing a controller:
Transport the controller in the original container to
minimize vibration and shock damage.
Verify that all parts shipped with the controller.
Do not drop the controller or subject it to physical
shock.
Parts Included
one controller with removable terminal blocks (Power
and SA/FC bus are removable)
one installation instructions sheet
