expansion modules expand the number of points

connected to a Network Automation Engine (NAE), Field

Equipment Controller (FEC), VAV Modular Assembly

(VMA), or Advanced Application Field Equipment

Controller (FAC) to monitor and control a wide variety of

HVAC equipment.

IOM field controllers operate on an RS-485 BACnet®

MS/TP Bus and integrate into Johnson Controls®and

third-party BACnet systems.

Important: The MS-IOM171x-0U and MS-IOM271x-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 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

Wiring

Risk of Electric Shock: Disconnect or isolate all power

supplies before making electrical connections. More than

one disconnection or isolation may be required to

completely de-energize equipment. Contact with

components carrying hazardous voltage can cause

electric shock and may result in severe personal injury

or death.

Avertissement: Risque de décharge électrique:

Débrancher ou isoler toute alimentation avant de réaliser

un branchement électrique. Plusieurs isolations et

débranchements sont peut-être nécessaires pour

-couper entièrement l'alimentation de l'équipement. Tout

contact avec des composants conducteurs de tensions

dangereuses risque d'entraîner une décharge électrique

et de provoquer des blessures graves, voire mortelles.

Risk of Property Damage: Do not apply power to the

system before checking all wiring connections. Short

circuited or improperly connected wires may result in

permanent damage to the equipment.

Mise En Garde: Risque de dégâts matériels: Ne pas

mettre le système sous tension avant d'avoir vérifié tous

les raccords de câblage. Des fils formant un court-circuit

ou connectés de façon incorrecte risquent

d'endommager irrémédiablement l'équipement.

Important: Do not exceed the controller electrical

ratings. Exceeding controller electrical

ratings can result in permanent damage to

the controller and void any warranty.

Important: Use copper conductors only. Make all wiring

in accordance with local, national, and

regional regulations.

Important: Electrostatic discharge can damage

controller components. Use proper

electrostatic discharge precautions during

installation, setup, and servicing to avoid

damaging the controller.

For detailed information on configuring and wiring an

MS/TP Bus, FC bus, and SA bus, refer to the MS/TP

Communications Bus Technical Bulletin (LIT-12011034).

Terminal Blocks and Bus Ports

See Figure 3 for terminal block and bus port locations on

the controller. Observe the following guidelines when

wiring a controller.

Input and Output Terminal Blocks

Most of the input terminal blocks are mounted on the

bottom of the controller and the output terminal blocks

are mounted on the top of the controller. See Table 3 for

more information about I/O terminal functions,

requirements, and ratings.

SA/FC Bus Terminal Block

An IOM can be connected to a Sensor/Actuator (SA) bus

or a Field Controller (FC) bus, but not to both buses

simultaneously. The SA/FC bus terminal block is a

removable, 4-terminal plug that fits into a board-mounted

jack.

When connecting the IOM to an FC bus, wire the bus

terminal block plugs on the controller and the other

controllers in a daisy-chain configuration using 3-wire

twisted, shielded cable as shown in the FC Bus Terminal

Block wiring figure below. See Table 5 for more

information.

Figure 4: FC Bus Terminal Block Wiring

When connecting the IOM to an SA bus, wire the bus

terminal block plugs on the controller and other SA bus

devices in a daisy-chain configuration using 4-wire

twisted, shielded cable as shown in Figure 5. See Input

and Output Wiring Guidelines for more information.

5IOM1711 and IOM2711 Input/Output Module Installation Instructions

Figure 5: SA Bus Terminal Block Wiring

Note: The SA PWR/SHLD terminal does not supply 15

VDC. The SA PWR/SHLD terminal is isolated and

can be used to connect (daisy chain) the 15 VDC

power leads on the SA bus (Figure 5) or the cable

shields on the FC bus (Figure 4). The SA bus

supervisor (FAC, FEC, or VMA) supplies 15 VDC

to devices on the SA Bus requiring power.

SA/FC Bus Port

The SA/FC bus port on the front of the controller is an

RJ-12, 6-position modular jack that provides a connection

for devices on the SA bus.

The SA/FC bus port is connected internally to the SA/FC

bus terminal block. See Table 5 for more information.

The SA/FC Bus Port pin assignment is shown in the Pin

Number Assignments figure below.

Figure 6: Pin Number Assignments for Sensor, SA

Bus and FC Bus Ports on Controllers

Supply Power Terminal Block

The 24 VAC supply power terminal block is a gray,

removable, 3-terminal plug that fits into a board-mounted

jack on the top right of the controller.

Wire the 24 VAC supply power wires from the transformer

to the HOT and COM terminals on the terminal plug as

shown in the following figure. The middle terminal on the

supply power terminal block is not used. See Table 5 for

more information about the Supply Terminal Block.

Figure 7: 24 VAC Supply Power Terminal Block Wiring

Important: Connect 24 VAC supply power to the

controller and all other network devices so

that transformer phasing is uniform across

the network devices. Powering network

devices with uniform 24 VAC supply power

phasing reduces noise, interference, and

ground loop problems. The controller does

not require an earth ground connection.

Wireless Network Applications

Important: Wireless operation is not approved for

smoke control applications. 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

Terminal Wiring Guidelines,

Functions, Ratings, and

Requirements

Input and Output Wiring Guidelines

Table 3 provides information and guidelines about the

functions, ratings, and requirements for the controller

input and output terminals; and references guidelines for

determining proper wire sizes and cable lengths.

In addition to the wiring guidelines in Table 3, observe

these guidelines when wiring controller inputs and

outputs:

• Run all low-voltage wiring and cables separate from

high-voltage wiring.

• All input and output cables, regardless of wire size or

number of wires, should consist of stranded, insulated,

and twisted copper wires.

• Shielded cable is not required for input or output

cables.

• Shielded cable is recommended for input and output

cables that are exposed to high electromagnetic or

radio frequency noise.

• Inputs/outputs with cables less than 30 m (100 ft)

typically do not require an offset in the software setup.

Cable runs over 30 m (100 ft) may require an offset

in the input/output software setup.
