Eaton Flexi Bi-Wire & Conventional Fire Alarm Control Panel
Code: TF100-772-01
The Eaton Bi-Wire Flexi Fire Alarm Panel delivers the advantages of both two-wire and conventional systems in one versatile solution.
Each zone can be set up to support either wiring method, giving you the freedom to combine conventional and two-wire devices throughout the installation. This adaptability makes it well-suited for both new projects and refurbishments where existing cabling or equipment needs to be retained.
The panel features the same user-friendly interface as Eaton’s well-known 8-Zone Conventional Panel, ensuring straightforward setup and ongoing maintenance.
Fully certified to EN54 Parts 2 and 4 and developed in line with BS 5839 guidance, the Bi-Wire Flexi provides dependable fire detection that meets current UK fire safety requirements.
Whether you want the efficiency of two-wire loops or the functionality of specialised conventional devices, this panel is designed to fit your needs.
Supports both conventional and two-wire detection on the same system
Each zone configurable independently
Compatible with a wide range of devices
Easy-to-use interface for fast setup and servicing
Ideal for mixed-system upgrades and phased retrofits
Certified to EN54 Parts 2 & 4
Meets BS 5839 fire safety recommendations
