The LMSeries:

The most advanced,cost-effective product line in the industry

The LM is a surge protective device (SPD) that offers continuous protection from damaging transients and electrical line noise. The LM utilizes patented circuitry to monitor the status of all protection modes, including neutral to ground. Should protection be unavailable in any mode, the green LED will be extinguished, and the red LED will be illuminated. In addition, high isolation form C dry contacts provide for remote monitoring of suppression system failure, under voltage, and phase and power loss. LM patented suppression integrity monitoring indicates failure for both shorted or opened suppression components.

The LM Series can be a facility-wide product family and may be installed from service entrances to distribution panels to branch panels.
