Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) BACnet points list

Updated 12 November 2026

Short answer

The FMS-2000C controls and monitors room pressure (and optionally flow, temperature and humidity) with a touch display, four analog inputs, two thermistor inputs, four analog outputs, four digital inputs and four relays. It talks BACnet MS/TP. The BACnet table has 93 objects: I/O, setpoints, alarm and warning limits, network-written values, airflow and volumetric offset, output overrides and input override values, deadbands, isolation mode commands and alarm status.

This page lists 93 BACnet objects for the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) — 59 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Johnson Controls’s own free documentation, linked below.

BMS integration notes: Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)

Integration in brief

Map the primary isolation mode command, the room pressure setpoint, the measured room pressure, the damper output and the primary alarm status. Write network variables (AV 43-46) only if the BAS supplies those values.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)

How many BACnet points does the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) have?

This list has 93 BACnet objects: 6 analog inputs, 4 analog outputs, 66 analog values, 4 binary inputs, 4 binary outputs, 9 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) BACnet points are writable?

59 of the 93 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.

Where is the official Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP) BACnet documentation?

The source is FMS-2000C Critical Environment Controller User Guide (LIT-12013504), revision 2025-08, published free by Johnson Controls at https://docs.johnsoncontrols.com/bas/api/khub/documents/qp2ryilUcG~ViAADcbhQ9g/content.

What are the minimum BACnet points to integrate the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)?

Start with MV 1 Primary isolation mode (Isolation mode: 1 positive, 2 negative, 3 neutral); AV 1 AI-1 setpoint for room pressure (Room pressure setpoint); AI 1 Analog input 1, default: isolation pressure (Room (isolation) pressure); AO 1 Analog output 1, default: damper position (Damper position output); BI 1 Digital input 1, default: door switch (Door switch); MV 3 Primary alarm status (Primary alarm: 1 normal, 2 warning, 3 alarm).

How do I enable BMS control of the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)?

Primary isolation mode (MV 1) is writable: 1 positive, 2 negative, 3 neutral.

Can the BMS supply sensor values to the Johnson Controls Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)?

AV 43-46 are writable network variables for humidity, temperature, air changes and pressure sent from the BAS.

How do I check these points on the real Triatek FMS-2000C Critical Environment Controller (BACnet MS/TP)?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
