Suitable for use on telephone lines with a maximum (or ringing) voltage of up to 190 volts.
For telephone lines with a British style, jack plug and socket, connection use ESP TN/JP. For telephone lines with RJ11 connections protect the middle 2 (of 6) conductors with ESP TN/RJ11-2/6, the middle 4 (of 6) with ESP TN/RJ11-4/6 or all 6 with ESP TN/RJ11-6/6.For wire-in applications the high performance ESP TN or ready-boxed derivative ESP TN/BX or ESP TN/2BX, can be used. To protect PBX telephone exchanges and other equipment with LSA-PLUS connections .
Application
Use these to protect equipment plugged into a telephone or ISDN socket:
computers and computer modems faxes, phones and answer machines dial-up fire/burglar alarms telemetry equipment.
Features and benefits
Controls transient overvoltages to a low level to ensure maximum protection for your equipment. Provides repeated protection in lightning intense environments. ESP TN/JP and ESP TN/RJ11-6/6 give protection between all six conductors, so whichever wires your system communicates through you can be sure your equipment is fully protected. ESP ISDN/RJ45-8/8 gives protection between ll 8 conductors, fully protecting attached equipment no matter which wires the system uses. Correctly applied, ESP TN/RJ11-2/6, ESP TN/RJ11-4/6 and ESP ISDN/RJ45-4/8 protect all signalling conductors. Supplied ready for flat mounting. Sturdy ABS housing. Simple installation. Substantial earth stud to enable effective earthing. Straightforward and comprehensive installation instructions with every unit. UK Oftel Approval NS/G/1235/W/100025 5 year warranty.
Installation
Connect in series with the telephone line or ISDN line. These units are usually installed close to the equipment being protected and within a short distance of a good electrical earth.
