IOM2710 and IOM3710 Input/Output Modules Installation Instructions 1
Applications
The Input/Output Module (IOM) 2710 and IOM3710 are
members of the Metasys® system Field Equipment
Controller (FEC) family. The IOM controller provides
increased capacity to larger FEC applications when
used on the Sensor-Actuator (SA) Bus. The IOM
controller can also be used on the Field Controller (FC)
Bus to connect additional I/O points to the system.

Installation
Observe the following guidelines when installing the
IOM controller:
• Transport the IOM controller in the original
container to minimize vibration and shock damage
to the IOM.
• Do not drop the IOM controller or subject it to
physical shock.
Materials and Special Tools Needed
You need either of the following items to install the IOM
controller:
• three fasteners appropriate for the mounting
surface (#8 screws or M4 screws)
• one 20.3 cm (8 in.) or longer piece of DIN rail and
appropriate hardware for mounting the DIN rail
Mounting
Follow these guidelines when mounting an IOM
controller:
• Ensure that the mounting surface can support the
IOM controller and any user-supplied enclosure.
• Mount the IOM controller in the proper orientation.
See the Wall Mount Applications and DIN Rail
Mount Applications sections.
• Mount the IOM controller on an even surface
whenever possible.
• Use shims or washers to mount the unit securely
on the mounting surface.
• Mount the IOM controller in areas free of corrosive
vapors and observe the environmental limitations
listed in the Technical Specifications section.
IMPORTANT: The MS-IOM2710-0U and MS-
IOM3710-0U models are used in Metasys Release
8.1 smoke control applications and are 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 (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 requiredversions; 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 (LIT-12012487).

IOM2710 and IOM3710 Input/Output Modules Installation Instructions2
• Do not mount the IOM controller on surfaces that
are prone to vibration, such as duct work, or in
areas where electromagnetic emissions from other
devices or wiring can interfere with IOM controller
communication.
• Allow sufficient space for cable and wire
connections (minimum of 51 mm [2 in.] in each
direction).
On panel or enclosure mount applications, observe
these guidelines:
• Do not install the IOM controller in an airtight
enclosure.
• Mount the IOM controller so that the enclosure wall
or the transformer does not obstruct ventilation of
or radiate heat into the IOM controller housing.
Wall Mount Applications
Use the holes in the mounting clips for wall mount
applications.
To mount the IOM controller on a wall or other vertical
surface:
1. Ensure that the bottom mounting clip(s) are pulled
outward and snapped firmly into the extended
position and that the top clip is securely installed
(Figure 2).
2. Mark the location of the wall mount holes using the
dimensions in Figure 3, or hold the IOM controller
up to the wall as a template and mark the locations.
Note: Mount the IOM controller horizontally for proper
airflow.

3. Drill holes in the wall at the locations marked in
Step 2 and insert wall anchors (if necessary).
4. Position the IOM controller and insert the screws
through the holes in the mounting clips, and
carefully tighten all the screws.
DIN Rail Mount Applications
To mount the IOM controller on a DIN rail:
1. Securely mount the section of DIN rail horizontally
and centered in the required space.
2. Carefully pull down (outward) the bottom mounting
clips until they lock in place (Figure 4).
Note: The top mounting clip is not used on DIN
rail applications. You may remove the clip.
3. Hang the IOM controller on the DIN rails using the
DIN rail hooks on the back of the IOM controller.
4. Secure the IOM controller on the DIN rail by
pressing the bottom mounting clips up until they
snap into place.
To remove the IOM controller from the DIN rail, snap
the bottom DIN clips to the outboard position and
carefully lift the IOM controller off the DIN rail.
Wiring
Refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for more information on MS/TP
devices.
To wire the IOM controller:
1. Terminate wiring per engineering drawings.
2. If the IOM is connected to the FC Bus of a Network
Automation Engine (NAE) or Network Control
Engine (NCE), wire the FC Bus in a daisy chain.
IMPORTANT: Do not overtighten the mounting
screws. Overtightening the screws may damage the
mounting clips or IOM housing.

IMPORTANT: Do not connect 24 VAC supply
power to the IOM controller before finishing wiring
and checking all wiring connections. Short circuits or
improperly connected wires may result in permanent
damage to the equipment.
IMPORTANT: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations. The IOM controller is a
low-voltage (<30 VAC) device. Do not exceed the
IOM controller electrical ratings.
IMPORTANT: Prevent any static electric discharge
to the IOM controller. Static electric discharge can
damage the IOM controller and void any warranties.

3. If the IOM is connected to the SA Bus of an NCE or
FEC, wire the SA Bus in a daisy chain (Figure 6).
Note: The SA/FC Bus Port (RJ-12 6-position
modular connector) provides 15 VDC on one of its
pins, which is used to power the MS-BTCVT.
Note: If the IOM controller is at one end of the SA
Bus daisy chain, set the End-of-Line (EOL) switch
to ON.
4. Connect power to the IOM controller.
5. Download and commission the IOM controller. See
the Commissioning section.
SA/FC Bus Port
The SA/FC Bus port on the front of the IOM is an
RJ-12, 6-position modular jack that provides a
connection for the Wireless Commissioning Converter.
See Table 1 for more information. The SA/FC Bus Port
pin assignment is shown in (Figure 7).

Wiring Requirements
Setup and Adjustments
The IOM controller can reside on either the FC Bus or
the SA Bus. When you set the address, you are setting
the address for the specified bus. The IOM controller
can only be on one bus at a time.
Determining the FC Bus or SA Bus Address
The ADDRESS DIP switch sets a unique address for
the controller (or module) on the FC Bus or SA Bus.
Set the address to 4-127 for an IOM. For best
performance, all devices on the same Bus (FC Bus or
SA Bus) should have consecutive addresses. Do not
use Addresses 128 and above when connecting the
IOM to the FC Bus or SA Bus. For more information,
refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034).
Table 3 shows and describes the valid FC Bus and
SA Bus devices addresses for FECs and IOMs on
Johnson Controls® MS/TP communications bus
applications.

controllers on the SA or FC Bus.

IOM2710 and IOM3710 Input/Output Modules Installation Instructions8
Setting the FC Bus or SA Bus Address
For most devices on an FC Bus or SA Bus, the
(non-supervisory) device address is set using the DIP
switches on the device’s ADDRESS DIP switch block.
The DIP switch blocks are binary switch blocks and
each switch represents a binary numerical value when
the switch is set to the ON position. For example,
positioning switches 16, 4, and 1 to ON, as shown in
Figure 9, sets the device address to 21. Always set
switch 128 to OFF to enable wired FC or SA Bus
operation.
FC Bus or SA Bus EOL Switch
The EOL switch applies power termination to the
device’s FC Bus or SA Bus. If the IOM is at the
End-of-Line (EOL) position on the Bus, set the EOL
switch to the ON position. Otherwise, set the EOL
switch to the OFF position (Figure 10). The controller
ships with the EOL switch set in the OFF position.
Commissioning
Commission the IOM controller with the Controller
Configuration Tool (CCT) software. For details, refer to
the Controller Tool Help (LIT-12011144).
Troubleshooting
Use Table 4 to troubleshoot the IOM controller.
Repair Information
The MS-IOM2710-0U and MS-IOM3710-0U models
are UL 864 10th Edition UUKL/ORD-C100-13 UUKLC
listed for smoke control. If the device fails to operate
within its specifications, contact the Johnson Controls
Repair Center in Louisville, Kentucky, at 1-502-671-
