Walker Systems NBC Native BACnet Controller

Compatibility with product line and installed base

The Walker Technologies NBC allows any Walker Stand Alone Controller (SAC) panel to communicate via BACnet with other BACnet devices on a network.

Highly Configurable

The NBC is highly configurable: the user can configure the NBC to BACnet-enable only 1 panel, up to 49 panels connected to a smartLAN network, or any combination of panels in between. The NBC BACnet-enables up to 240 points per panel, transforming these points into BACnet objects, and again the choice of which points to enable is highly configurable by the user.

Quick and Easy Integration Into Sites

The NBC is designed to integrate BACnet functionality into new or existing sites very quickly and easily. The NBC can be attached to any panel on a smartLAN without interrupting the service of that smartLAN. Once the NBC is connected to a panel and has been configured to connect to a BACnet network, that panel instantly becomes BACnet-enabled with no extra configuration needed. If added configuration is desired, the NBC's Telnet interface allows all configuration options to be modified remotely, and also facilitates remote upgrades to allow feature enhancements in the field.
