Frequently asked questions about ProReact EN Digital Linear Heat Detection

What is EN54-28:2016?

This European Standard applies to non-resettable line-type heat detectors consisting of a sensing element using an electrical sensor cable which can be connected to a sensor control unit or either directly or through an interface module to a control and indicating equipment intended for use in fire detection and fire alarm systems installed in and around buildings and civil engineering works.

Why are European Standards important in the fire safety industry?

They provide a technical basis to assess the performance of construction products and they enable manufacturers to draw up declarations of performance and affix CE and UKCA marking. Products that are resistant to fire or react to fire fall under the definition of construction products in the European Union.

Was Thermocable the first company to gain certification according to EN54-28?

Yes, to our knowledge we were the first manufacturer to have a full system (consisting of detection cable, an interface unit and end of line unit) certified according to EN54-28.

How is Thermocable’s ProReact EN Digital LHD system different to the ProReact Digital LHD range?

Thermocable had to introduce hardware and software modifications to its existing ProReact Digital LHD range in order to meet the requirement of EN54-28. As a result, these two systems are materially different and are not cross-compatible. I.e., you cannot use ProReact Digital LHD cable with a ProReact Digital Sensor Control Unit (DSCU).

An unintended consequence of making these changes is the reduction in maximum zone length per zone of detection cable. This is 1,000 metres per zone for the ProReact EN Digital LHD system. However, please note that two zones of detection cable can be connected to a single ProReact Digital Sensor Control Unit.

Which system components are covered by the EN54-28 certification?

The ProReact EN Digital LHD cable (various alarm temperatures available), the ProReact Digital Sensor Control Unit (DSCU) and the ProReact Digital End of Line Unit (EOLU) are all listed as components on the system approval certificate.

What are the standard reel lengths of the ProReact EN Digital LHD cable?

This detection cable is available in 100 metre, 200 metre or 500 metre reel lengths as standard. Non-standard lengths can be supplied but will incur a small surcharge. Please note that the maximum available reel length is 500 metres per spool.

What is the chemical compatibility of the low smoke zero halogen outer coat on ProReact EN Digital LHD cable?

The low smoke zero halogen outer coat has good resistance against ammonia, copper nitrate, hydrofluoric acid and acetic acid.
