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

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.
