Johnson Controls IOM3731-0A INSTALLATION MANUAL

Models to support both BACnet MS/TP and N2. with

auto-detection of the communications protocols

Controller auto-detects the BACnet MS/TP or N2 protocol

that is connected to it, which enables the same controller

to support multiple communication protocols without

the need to purchase a special model per protocol, and

without extra manual setup.

BACnet Testing Laboratories (BTL) listed and certified

Ensures openness and interoperability with other BTL

listed devices. BTL is a third-party agency, which validates

that BAS vendor products meet the BACnet industry

standard protocol.

BACnet automatic discovery

Supports easy controller integration into a Metasys BAS.

Wireless ZFR and ZFR Pro support

Provides a wireless alternative to hard-wired MS/TP

networking, offering application flexibility and mobility

with minimal disruption to building occupants, and also

simplifies and speeds up replacements.

Integral real-time clock

An integral real-time clock, which enables the controllers

to monitor and control schedules, calendars, and trends,

and operate for extended periods of time as stand-alone

controllers when offline from the Metasys system network.

Pluggable screw terminal blocks

Pluggable input/output wiring terminal blocks provide

electrical installers and field technicians the ability to

quickly and easily install and service a controller without

the need to disconnect and reconnect the input/output

wiring.

Auto-Tuned Control Loops

Reduce commissioning time, eliminate change-of

season re-commissioning, and reduce wear and tear on

mechanical devices.

The M4-XPM series I/O expansion modules can serve

in one of two capacities depending on where they are

installed in the Metasys system. When installed on

the Sensor/Actuator (SA) Bus of a Metasys equipment

controller, an XPM expands the input and output

interfaces that can be used with that equipment

controller. When installed on the Field Controller (FC) Bus

of a Metasys network engine, an XPM can be used as I/O

point multiplexors to support monitoring and control from

a Metasys network engine. The point multiplexor can also

be useful for sharing points between other equipment

controllers on the FC Bus using peer-to-peer connectivity.
