Johnson Controls IOM3711 Installation Manual

Application
The IOM37 input/output expansion module is a part of the
Metasys system Field Equipment Controller family. Input/
®
Output Module (IOM) expansion modules expand the
number of I/O points connected to a Network Automation
Engine (NAE), Network Control Engine (NCE), 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 expansion modules operate on an RS-485 BACnet
MS/TP Bus and integrate into Johnson Controls
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 operation of the
Input/Output Module (IOM) is not affected by the
selection of the BACnet or the N2 protocol in the host
controller, when the (IOM) is connected to the host
controller using the SA bus. Only the BACnet protocol
is supported when the (IOM) is connected directly to
the trunk using the FC bus.
Important: In Metasys system smoke control
applications, use only the MS-IOM3710-0U and MS-
IOM3711-0U 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 Listed Metasys system devices. The UL 864
UUKL 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).
