Key Features

  • Quickly simulate fault and alarm conditions
  • Secure, weatherproof enclosure 
  • Provides a simple and straightforward method to carry out a functional test on the system
  • Supplied with 2 IP67*1 rated cable glands
  • EN54-28:2016 approved


The FyreLine EN54 Fixed End of Line is designed to effectively terminate up to two zones of FyreLine EN54 Fixed linear heat detection cable in a secure, weatherproof enclosure. It has built in switches to simulate fault or alarm conditions to allow the system to be fully tested in situ.

The FyreLine EN54 Fixed End of Line is particularly suitable for when the system is used in interlock mode to prevent false alarms. In this mode, two fixed LHD cables are run side-by-side and an alarm is only activated on the fire alarm control panel when both cables trigger. 



EN54-28 is the European Standard for non-resettable line-type heat detectors that consist of a sensing element that uses electrical sensor cable. It specifies the requirements and performance criteria; and the corresponding test methods. This European Standard also covers non-resettable line-type heat detectors intended for use in the local protection of plant and equipment.

Please note: to comply with EN54-28, the FyreLine EN54 Fixed Controller, FyreLine FyreLine EN54 Fixed EOL and FyreLine EN54 Fixed LSZH LHD Cable must be used as a complete system.

All products in the FyreLine EN54 range are approved for use within the European Economic Area (EEA) and comply with the EU’s New Approach Directives and show the CE mark to indicate that they fulfill the requirements of relevant European product directives; meet all the requirements of the relevant recognized European harmonized performance and safety standards; and are fit for purpose and will not endanger lives or property.
