By installing the Intermatic 2-Line Telephone Protector where your phone line enters your home, you'll be protecting your phone, fax, modem and/or DSL lines from the surges that can destroy their connected components. The Intermatic 2-Line Telephone Protector even carries a 5-year warranty with a $10,000 connected-equipment warranty.

    Usage and Installation
    The surface-mounted 2-Line Telephone Protector is designed for low-voltage metallic phone and data lines and features balanced protection between Tip, Ring, and Ground for each of two lines. Terminal block-type connectors allow installation without special tools. Made of epoxy-enameled steel, the 2-Line Telephone Protector has been designed to minimize interference with the signal.

    Protection Component Details
    The protection component is a three-element gas tube, which guarantees continued balance between the Tip and Ring lines at all times. Accidental or "sneak" current is minimized by the use of a Positive Temperature Coefficient Resistor (PTCR), which will reset and allow normal phone line operation once the abnormal current situation has been corrected.

    The gadget looks well made, and it's easy to install. Of course, I cannot tell whether the Protector works unless lightning hits my telephone line! So, I don't want to know whether it works!
