Defining an Open System
Building control systems are often a collection of use-specific subsystems such as lighting, HVAC, and security. At Echelon, we do things differently. We treat every device in the building as an equal on a control network. So, instead of needing three motion sensors — one each for lighting, HVAC, and security — building integrators can use a single motion sensor for all their systems. We call this an open system.
Benefits of an Open System
- Lower installation costs.
- Greater expandability.
- Easier to manage.
- Extremely flexible.
- Integrates easily with future building automation technologies such as XML and IP.
LonMark Open Systems
- Contain LonMark certified products from multiple manufacturers.
- Use the LNS network operating system, which includes a database that holds the image of the building control system.
- Don't require gateways, except to interact with legacy systems or as required by codes.
End users and consultants should specify the use of LonMark certified products — as well as LNS based network tools for design, installation, and commissioning — whenever possible. The combination of open products and standard services lets integrators easily build a complete open system with products from multiple manufacturers.
