Lon (LonWorks) is an international standard open-protocol and the world's leading technology for networking building services devices.

Closed systems and proprietary protocols lock clients into a lifetime commitment to a single proprietary solution and vendor, and can only integrate with other systems through specialist gateways. Lon frees Clients from reliance on a single source of supply. Clients select the best-of-breed for detectors, lighting controls, HVAC and access-control units confident that these can be connected into a fully interoperable building control network using software �plug-ins� and standard configuration software: support staff can configure, manage and maintain any Lon system avoiding the need to learn protocols for different systems.
