IOM47 Input/Output Module Installation Instructions
MS-IOM4711-x
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), Network Control
Engine (NCE), 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®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls® and third-party BACnet systems.
Note: At CCT Release 10.1 and later, a new capability
was introduced allowing 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: In Metasys system smoke control
applications, use only the MS-IOM4711-0U
and MS-IOU4710-0U 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/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 UUKL Tenth
Edition Smoke Control System Technical
Bulletin (LIT-12012487).

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
