Description
Honeywell VPLEX-VSI V-Plex Short Circuit Isolator Module for Polling Loop Systems
The Honeywell VPLEX-VSI is a specialized short circuit isolation module designed for all Resideo V-Plex two-wire polling loop systems, providing automatic fault detection and branch isolation to enhance system reliability and life safety. When a short circuit occurs on a polling loop branch, the VPLEX-VSI illuminates a trouble LED and automatically isolates the defective branch from the system, preventing a single fault from compromising the entire polling loop. Powered directly from the V-Plex two-wire polling loop without requiring external power, this module can be strategically placed on any major or minor branch to separate burglary devices from fire devices, significantly reducing troubleshooting time and maintenance costs while maintaining critical system protection during fault conditions.
Key Features:
- Automatic short circuit detection and branch isolation; protects entire polling loop from single branch failures while maintaining system operation
- LED trouble indicator for rapid fault identification; reduces troubleshooting time and maintenance costs by clearly identifying the isolated defective branch
