The Eaton Flexi Bi-Wire 4 Zone Fire Alarm Kit delivers a full bi-wire fire detection solution engineered for quick installation and dependable operation.

Using the same bi-wire principle as the Fike Twinflex Pro system, it enables detectors, sounders, and call points to share a single cable pair for each zone.

This makes it an excellent choice for installers already familiar with Twinflex systems or for upgrading existing bi-wire setups.

The kit includes a 4-zone Flexi Bi-Wire Control Panel, photo-thermal multi-sensor detectors, bi-wire sounder bases, manual call points, and backup batteries, providing all key components in one ready-to-install package.
Each FXN922 detector combines optical and heat sensing to enhance fire verification and reduce unwanted alarms.

Built on Eaton’s reliable bi-wire platform, the system offers consistent, long-term performance suitable for both commercial and residential use.

With four zones available, it is ideal for sites needing wider coverage or clearer area separation, such as HMOs, offices, shops, workshops, and small industrial premises.
