IOM3721 Input/Output Module Installation Instructions
MS-IOM3721
Application
The IOM3721 field controller is a part of the Metasys®
system Field Equipment Controller family. Input/Output
Module (IOM) field controllers expand the number of
points connected to an 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 Heating, Ventilating, and Air Conditioning
(HVAC) equipment.
IOM field controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into the Web-based Metasys system.
Important: In Metasys system smoke control
applications, use only the MS-IOM3710-0U
models that are UL Listed, UUKL/UUKLC
864 Listed, Smoke Control Equipment. For
Metasys system smoke control applications,
you must refer to the Metasys System UL
864 Ninth Edition UUKL/UUKL7 Smoke
Control System Technical Bulletin
(LIT-12011252) for detailed requirements
and procedures for installing and operating
UUKL/UUKLC 864 Listed Metasys system
devices. Failure to meet the requirements
or follow the procedures in the Metasys
System UL 864 Ninth Edition UUKL/UUKL7
Smoke Control System Technical Bulletin
(LIT-12011252) can void the UUKL/UUKLC
864 listing for Smoke Control Equipment.
