Jointing/Terminal Boxes 

On site installation of PROLINE digital linear heat sensor cables will involve at least one of the following wiring connections: 

A) Sensor cable to Sensor cable: For............

 i) existing installation length extensions,

ii) sectional replacements/repairs

iii) to achieve multiple alarm temperatures on a single zone by jointing cables with different alarm temperature ratings.

B) Sensor cable to Short term fire-proof interconnecting cabling

 Where interface units are installed “remote” from the risk area

C) Remote end termination of sensor cable

 Termination box fitted with end of line resistor for open circuit fault condition monitoring.

 With Junction boxes remaining the most reliable and most commonly end user specified method for sensor cable joints and / or end of line terminations,PROLINE has researched a number of manufacturers of such boxes-suitable for Industrial risk applications, and offers the following units – based upon quality and price.
