Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) BACnet points list
Updated 12 November 2026
The SPM-3000 Micro Guardian monitors one room's differential pressure and alarms on it. On BACnet MS/TP it gives the pressure reading, the room mode (off, positive, negative), separate alarm limits for each mode and the alarm status.
This page lists 14 BACnet objects for the Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) — 11 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Paragon Controls’s own free documentation, linked below.

BMS integration notes: Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP)
Set the room mode with MSV 1 (positive or negative) and read the pressure AI 1 and the alarm status MSV 2.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| MV 1 | Operating Mode | Room mode: 1 off, 2 positive, 3 negative | Write |
| AI 1 | Process Value | Room differential pressure | Read |
| MV 2 | Alarm Status | Alarm: 1 none, 2 high, 3 low | Read |
Network setup
- MS/TP MAC address 2-127, unique on each trunk; set at the device (see the device O&M).
- Baud 9600, 19200, 38400 or 76800; the SPM-3000 section gives 38400 as the default.
- Turn the BACnet terminator switch ON only on the two end devices of the trunk.
- Device instance 1,002 to 65,535.
Watch out for
- Alarm limits are separate for positive (AV 2/3) and negative (AV 4/5) mode.
- AV 7 is the front-panel password; leave it alone unless asked.

Integration notes
- The manual gives each object as '<object type> <number> - <label>'; the label is used here as the object name.
- The process value units follow MSV 3.
- Device instance range 1,002 to 65,535 per the manual.
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 SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP)
How many BACnet points does the Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) have?
This list has 14 BACnet objects: 1 analog input, 9 analog values, 1 binary value, 3 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) BACnet points are writable?
11 of the 14 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 Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP) BACnet documentation?
The source is BACnet Communication Operation & Maintenance Manual (MicroTransEQ, MicroTransII, SPM-3000, SPM-4000), revision Revision Level 003, published free by Paragon Controls at https://paragoncontrols.com/wp-content/uploads/2021/03/BACnet-IOM.pdf.
What are the minimum BACnet points to integrate the Paragon Controls SPM-3000 Micro Guardian space pressure monitor (BACnet MS/TP)?
Start with MV 1 Operating Mode (Room mode: 1 off, 2 positive, 3 negative); AI 1 Process Value (Room differential pressure); MV 2 Alarm Status (Alarm: 1 none, 2 high, 3 low).
How do I check these points on the real SPM-3000 Micro Guardian space pressure monitor (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.
