- Supports two zones of up to 1000m
- EN54-28:2016 approved
- Provides accurate location of overheat event
- Full fault monitoring
- CE marked
Overview
The FyreLine EN54 Fixed Controller is a dual zone module that is capable of monitoring up to two zones of FyreLine EN54 Fixed Linear Heat Detection (LHD) Cable. The FyreLine EN54 Fixed Controller continuously monitors up to two zones of fixed LHD cable for a fault (open circuit) or an alarm (overheat or fire condition).
If an overheat or fire situation is triggered, the FyreLine EN54 Fixed Controller unit sends a signal of alarm to the fire alarm control panel and automatically calculates and displays the distance along the cable to the alarm point, giving the end user the exact location of the event.
Each zone can operate independently in interlock mode and a separate alarm and normally conducting fault output are provided for each zone.
The unit is intended to be installed between the Fixed Linear Heat Detection cable and a conventional or addressable fire alarm control panel and has power, fault and alarm lights, as well as volt-free outputs for fault and alarm, corresponding to each zone.
The FyreLine EN54 Fixed Controller may also be connected to an industrial process control system using the two wire RS-485 Modbus RTU/ASCII output.
If a fault is detected, the corresponding fault output stops conducting, triggering a fault at the fire alarm control panel. The fault outputs also stop conducting on power loss to the unit or microprocessor fault, also triggering a fault at the fire alarm control panel.

Approvals


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 recognised European harmonised performance and safety standards; and are fit for purpose and will not endanger lives or property.
