Introduction
Waterguard+ can be connected to and controlled directly from SD facilities or a third-party management system (eng. BMS - Building Management System) via BACnet IP.
Connection via BACnet IP makes it possible to view water alarms, malfunctions on valve units, read moisture and temperature measurements from WaterSensor+, battery status and open/close valves, as well as a number of other functions.
Waterguard+ systems that have already been installed will automatically be updated to the latest version of AbraOS so that these also support connection to SD systems via BACnet IP.
If the SD system does not support BACnet IP or it is not desirable to use this, you can alternatively use a smart IO module as a connection to the system. Please see this article for more info.
NB! Bacnet IP integration is only available with Linkbox+ 4G

Connection diagram
Solution description
One or more Linkbox+ 4G (B) are installed and valves are connected for water protection in the relevant building. Each individual Linkbox+ is connected to the SD system (T) via Cat cable (connected to the Ethernet port of the Linkbox+ 4G). Desired functions are programmed in the SD system's interface.
Data that can be transferred via BACnet IP integration
- Alarm on water detection
- Alarm in case of valve malfunction
- Humidity and temperature data from Wireless Water Sensor
- Battery status of Wireless Water Sensor(s)
- Voltage on Waterguard+ Central unit (Hub)
- Control signal for water OFF/ON
- IP configuration on Waterguard+ Central unit
Technical details
Default settings
- Dynamic IP address for connection to network with DHCP server and internet access via ethernet
- Port: 47808
Settings options
- IP address dynamic for connection to network with DHCP server but NOT internet access via ethernet
- By setting this setting, Linkbox+ will connect to 4G and preserve BACnet connection on local network via ethernet
- IP address static for connecting to a network without a DHCP server
- Same choice about internet via ethernet or not

You can add more wireless water sensors and more similar objects will be populated but with a different ID in front.
Product list
To connect a Waterguard+ installation to an SD system, only a Cat6 cable of the desired length is required (in addition to the Linkbox+ 4G). This is a standard network cable that can be purchased from electrical retailers etc.
Options: Abra Portal and remote control
In multi-dwelling buildings or commercial buildings, significant advantages can be achieved by using Abra as a top system. The building manager gets access to the Abra Portal (N) for management, which makes it possible to monitor the status of the installation, detect and prevent unwanted situations at an early stage.
Notification between housing units in the event of a fire, for example, increases security for residents without having to deal with different apps and solutions.
The Abra universe is in continuous development and more and more parts of the technical infrastructure in buildings will become compatible with Abra in the future. Click here for more information.
