Linear Heat Detection Solutions

FireClass by Johnson Controls Stand: 3a/F50

ProReact Linear Heat Detection provides an easy installation method for sensing changes in temperature. The technology offers an alternative over heat protection in a vast range of applications and industries, from car parks to factories and processing plants.

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.

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.

Benefits of ProReact EN Digital:

  • The first digital linear heat detection system to be certified to EN54-28:2016
  • Activation temperatures of 78°C and 88°C for ambient temperatures up to 45°C and 65°C respectively EN54-28, UL and RoHS complian
  • tAvailable 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
