The ProReact range of Digital Linear Heat Detection Cables is designed to trigger a response when a specific temperature is reached. If the temperature surrounding the cable reaches the activation temperature the two cores quickly come into contact and trigger an alarm.

These cables are known as ‘digital’ because they are ‘off’ below the activation temperature and irreversibly switched ‘on’ when the activation temperature is reached. The ProReact EN Digital LHD range is the first linear heat detection system to be approved to be approved to EN54-28:2016.

The ProReact Analogue Linear Heat Detection Cable provides an easy installation method for sensing changes in temperature. The analogue technology offers separate Pre-Alarm and Alarm outputs in order to maximise functionality, coupled with open and short circuit detection and discrimination.

Ambient temperature compensation maintains alarm temperature accuracy. The new EN Analogue LHD system meets the strict requirements of EN54-22:2015 as certified by VdS Global.

Benefits of ProReact EN Digital

  • EN54-28, UL and RoHS compliant
  • Available in 100m and 500m reels for each temperature
  • Wide coverage - up to 1,000 metres (3,280 ft) of ProReact EN Digital LHD cable per zone
  • Can monitor up to two zones of ProReact EN Digital LHD cable

Benefits of ProReact EN Analogue

  • Approved to EN54-22:2015 Class A1I, A2I and BI as certified by VdS Global
  • Up to 500 metres of linear heat detection cable per zone
  • ProReact EN Analogue LHD system is restorable following an activation if the sensor cable is not subject to a temperature above its maximum recoverable temperature of 125⁰C
  • Reduces the likelihood of false alarms through a temperature compensation feature
