In many buildings, intrusion detection systems and KNX building automation operate in parallel without their data being meaningfully connected. As a result, valuable information remains unused while additional sensors are installed at the same time. Lighting and temperature functions are often implemented using separate KNX sensors, even though security systems already provide this information. This leads to redundant hardware, increased installation effort and unused synergies in building operation – both technically and economically. This is where the integration of the NOX intrusion detection system into a KNX/EIB environment comes into play: Security-relevant events and system statuses are made available for building technology functions and specifically integrated into the building automation system. Lighting, temperature, blinds and shutters can therefore be controlled automatically whenever the status of the intrusion detection system changes. The NOX TIO functionality provides the basis for standardised, bidirectional communication between the security system and KNX. Existing sensors can therefore be used for multiple purposes, installation costs can be reduced, and security and energy efficiency can be intelligently combined – while maintaining clear system separation and ensuring future-proof integration into KNX building automation.

In buildings with KNX building automation and separate intrusion detection systems, lighting and temperature functions are often implemented redundantly using separate sensors, such as motion detectors. The aim is to use security-relevant events from the NOX system for building technology functions.

By using existing security and access data, energy consumption, space utilisation and operating processes can be controlled intelligently without installing additional sensors. Based on an example office building with approximately 5,000 m² of usable floor space, occupancy-based control can generate savings in the following areas:

ⓘ As existing security and access data is used, additional sensors are often not required. As a result, the integration frequently pays for itself within 6 to 24 months.

NOX not only connects security technology and building automation on a technical level but also makes existing security data usable for more economical building operation.

While conventional integrations primarily enable data exchange between systems, NOX actively uses status and event data to control building technology functions. This creates additional value for everyone involved in the project, from planning and implementation through to the subsequent operation of the building.
