Wildeboer OR4 pro smoke release device (RM4 optical smoke switch), BACnet IP BACnet points list
Updated 12 November 2026
The OR4 pro is a duct smoke release device built around the RM4 optical smoke switch. Its BACnet interface is small: airflow and contamination level as Analog Inputs, operating hours of the OR4 and RM4 as Analog Values, and alarm, contamination trend, fault and airflow flags as Binary Inputs. Nothing is writable.
This page lists 9 BACnet objects for the Wildeboer OR4 pro smoke release device (RM4 optical smoke switch), BACnet IP — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Wildeboer’s own free documentation, linked below.

Object ID lookup: Wildeboer OR4 pro smoke release device, point IDs by name
Integration notes
- Objects come from the EDE file (bacnet_EDE_OR4_02.csv) in Wildeboer's interface ZIP; all are marked not settable.
- Object names and state texts are German, kept as in the EDE (ASCII spellings such as Stroemung).
- The ZIP also holds a German PICS (or4pro_bacnet_pics_de_01-00) titled BACnet IP.
- Instance numbers follow the EDE object-instance column (1-9 running). The PICS in the same ZIP numbers the same objects per type instead (AI 1-2, AV 1-2, BI 1-5); check with a scan.
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 OR4 pro smoke release device (RM4 optical smoke switch), BACnet IP and exports what it actually has to Excel — free.
