Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP) BACnet points list
Updated 12 November 2026
The AMC-1DBx is a gas detection controller for large sensor networks. Over BACnet IP it exposes 4,119 fixed objects: a system state, then for each possible sensor a raw value, a cause state and a status string, and the same kind of blocks for relays, zones and analog outputs, plus file objects for logs, database and firmware. Configuration is not available over BACnet.
This page lists 25 BACnet objects for the Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP) — 6 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Armstrong Monitoring’s own free documentation, linked below.

BMS integration notes: Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP)
Watch MSI 0 for the overall state (32 = All Clear; the Relay bit means an alarm event). Then read only the sensors, relays and zones actually installed, using the device counts in OS 0, rather than discovering all 4,119 objects. COV on the cause-state objects avoids heavy polling.
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 |
|---|---|---|---|
| MI 0 | System Status State | Monitor state; 32 = All Clear | Read |
| AI 0 | Sensors Raw Input | Sensor 1 gas level, mV (800-4000 = 0-100 %) | Read |
| MI 1 | Sensor Cause State | Sensor 1 alarm/fail state; 32 = All Clear | Read |
| BI 0 | Relay Current Condition | Relay 1 state; check Polarity | Read |
| MI 1245 | Zone Cause State | Zone 1 alarm/fail state; 32 = All Clear | Read |
Network setup
- BACnet IP only (MS/TP not available); default IP 10.0.0.103/24, router 10.0.0.1, UDP 47808 (47808-47823 allowed).
- Default device ID 677003, network 0; BBMD address 0.0.0.0 when not used; BACnet IP time to live 60 s.
- Settings are made in the monitor's Interface > BACnet menu.
Watch out for
- Full discovery of 4,119 objects can take many minutes; add only the objects for installed devices.
- Up to 255 simultaneous confirmed COV messages; COV lists over 31 entries may cause segmentation aborts.
- After IP or BACnet changes treat the monitor as unreliable for another 120 s once it answers again.
- Writing push.fw or push.db starts a firmware or database update; never write those files casually.

Integration notes
- Objects come in fixed instance ranges, one object per sensor, relay, zone or output. Only the first object of each range is listed; the range is in each description (e.g. AI 0-987 = sensors 1-988).
- Object names are not printed; the group labels from the object list are used.
- Analog outputs are Analog Input objects AI 988-1115. OctetString Value objects (OS) carry packed status bytes.
- All objects are read-only except File objects; some support Out-Of-Service for testing interlocks.
- Cause states are 6-bit masks reported as values 1-32, where 32 = All Clear.
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 AMC-1DBx digital gas monitor (BACnet IP) and exports what it actually has to Excel — free.

Questions about the Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP)
How many BACnet points does the Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP) have?
This list has 25 BACnet objects: 2 analog inputs, 1 binary input, 14 files, 4 multi-state inputs, 4 octetstring values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP) BACnet points are writable?
6 of the 25 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 Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP) BACnet documentation?
The source is Digital Monitor 1DBx Series BAS Interface Manual, revision 2015-06-25, published free by Armstrong Monitoring at https://armstrongmonitoring.com/wp-content/uploads/2022/01/AMC-1DBx-BAS-Interface-Manual.pdf.
What are the minimum BACnet points to integrate the Armstrong Monitoring AMC-1DBx digital gas monitor (BACnet IP)?
Start with MI 0 System Status State (Monitor state; 32 = All Clear); AI 0 Sensors Raw Input (Sensor 1 gas level, mV (800-4000 = 0-100 %)); MI 1 Sensor Cause State (Sensor 1 alarm/fail state; 32 = All Clear); BI 0 Relay Current Condition (Relay 1 state; check Polarity); MI 1245 Zone Cause State (Zone 1 alarm/fail state; 32 = All Clear).
How do I check these points on the real AMC-1DBx digital gas monitor (BACnet IP)?
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.
