Designed to work on all Honeywell V-Plex polling loops, the VPLEX-VSI provides short circuit isolation for devices on compatible control panels. When a short occurs on a polling loop branch, it illuminates a trouble LED and isolates the defective branch from the system -- enhancing life safety and protection while reducing troubleshooting time and maintenance costs.

Features

• Detects and isolates polling loop branches with complete or resistive shorts, and overload or defective polling loop devices on initial power up
  
• Can be used to isolate burglary devices from fire devices, increasing life safety and protection
  
• LED indicator reduces troubleshooting time and maintenance costs
  
• Can be used on all qualified controls that support the ADEMCO V-Plex two-wire polling loop
  
• Operates automatically on qualified controls without the need for changes to existing control hardware or software
  
• Powered directly from the V-Plex two-wire polling loop
  
• Can be placed on any major or minor branch in any configuration on the polling loop
  
• Low power consumption
  
• Designed to meet appropriate regulatory agency requirements
