Description

The WS1500 Node Controller is an active network hub.  Special alarm and communications handling in the Node make it a powerful supervisory controller.

Using Nodes in large systems provides a means for effective zone management.  Nodes can be positioned to manage physical zones or common equipment, making all programming, diagnostic and supervisory functions for that zone or equipment group available at one location.  The Node is designed to handle high-volume trending and alarm buffering.
