Description

The FyreLine Resettable Linear Heat Detection (LHD) system, offered by Eurofyre, provides reliable overheat protection across various sectors, including power generation and oil and gas. The system comprises a heat-sensitive cable, a controller, and an end-of-line unit. The FyreLine Resettable LHD controller is certified to EN54-22 and UL 521 standards, ensuring its reliability as a fire detection device.

The controller continuously monitors the heat-sensitive cable, providing early warnings and alarms when overheating occurs. It supports Modbus communication and remote reset options for seamless integration and efficient management. Its resettable design contributes to cost-effectiveness and minimises downtime in fire safety systems.

Wiring is flexible, allowing connection to standard fire alarm panels or addressable monitor modules. Power can be supplied via a 24V DC output or a battery-backed EN54-4 or UL-listed power supply. The Modbus RS-485 RTU/ASCII output allows for additional data retrieval, such as fault and alarm status and ambient temperature, enabling its use as a distributed temperature sensing solution.

The controller features remote reset capabilities, requiring a 5-28V DC input for at least 3 seconds to initiate a reset. It also distinguishes between pre-alarm and alarm states based on temperature changes around the LHD cable. Certifications, including EN54-22 by VdS and UL 521 listing, ensure compliance with international fire safety standards.

Eurofyre provides datasheets, brochures, system guides, and approval certificates for the FyreLine Resettable Controller. The controller is available as a complete unit with an end-of-line module or as a replacement part.
