Don’t wait until your LIM fails!

Line Isolation Monitors (LIMs) often fail or become inaccurate and/or unreliable due to age, wear and tear, or damage. Upgrading your outdated or non-functional LIM with a new replacement from PG LifeLink can extend the life of your existing system in cases where the transformers, panelboards, wiring, and other components still have useful service life. Upgrading your system will also help ensure compliance with NFPA 99 requirements. 

Upgrades can be an economical alternative to replacing your entire Isolated Power System. 

Benefits of upgrading your LIM

  • Digital LIMs are more reliable and easier to use
  • Many analog style LIMs have reached their life expectancy
  • Older LIMs may no longer be serviceable due to component obsolescence
  • Updating obsolete analog LIMs to the latest digital technology reduces required testing frequency from monthly to annual, per NFPA 99 Section 6.3.4.1.4
  • Reduce maintenance costs and total cost of ownership
  • Add LIM Connect capability with the PG LifeLink Mark V LIM
  • Less expensive than replacing the whole Isolated Power System
  • Avoid costly, time-consuming, and dirty construction activity in your OR
  • Extend the useful life of your existing transformer and panelboard, if their capacity is adequate

PG LifeLink can also upgrade old Laser and X-ray Isolated Power Panels that are shared among multiple rooms. Upgrades provide Programmable Logic Control (PLC) for automatic selection of receptacles preventing overload or accidental shutdown of receptacles in use.

  • Has your LIM failed or been physically damaged?
  • Are replacement parts for your LIM no longer available?
  • Is your LIM built to a 2mA standard alarm point?
