V-Plex

Honeywell’s patented V-Plex polling loop technology literally defines price and performance on a simple pair of wires. By utilizing only two wires instead of four, V-Plex offers significant advantages over conventional four-wire installations — providing economical expansion of peripheral devices and point identification to your central monitoring station. In addition, reduced power consumption by V-Plex devices virtually eliminates the need for auxiliary power supplies. V-Plex offers a labor and time–saving maintenance feature that gives you the ability to diagnose and pinpoint defects while in maintenance mode.
