Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas. Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

2.2DESCRIPTION

The potential threats to ISDN and Telco hardware are vast: lightning, AC power induction, electrostatic discharge, ground potential differences, EMI/RFI interference and more. The Patton Model 552 has been designed to greatly reduce these risks. Just attach one unit to each of your telco ports and rest easy.

The Model 552 connects directly between twisted pair telco cables and their respective I/O ports. Grounding is accomplished using an external ground strap that provides a separate unit-ground to chassis- ground connection. By shunting threatening voltages directly to chassis ground, the Model 552 insures data integrity and protects connected equipment from damage.

The Model 552 uses a solid state design and sophisticated multistage hybrid circuits to achieve maximum protection without performance loss. Eight versions are available: Model 552-ST, 552-D8, and 552-L8 protect all 8 pins; Model 552-D6 protects six pins; Models 552-DDS, 552-D4, 552-U, 552-L4, 552-E1, 552-E1 CX, and 552-T1 protect four pins; and, Model 552-D2 protects two pins. All versions provide up to 1500 Watts of data line protection.

NOTE: Model 552-L8 may be used to protect Leased Line, DDS, T1, E1, ISDN PRI, and ISDN BRI “U” and “ST” interfaces.

WARNING!: This product will not provide complete protection should your equipment or building be subject to a direct lightning hit.
