Eaton Flexi Bi-Wire 4 Zone Fire Alarm Kit (604-0004 Equivalent)

The Eaton Flexi Bi-Wire 4 Zone Fire Alarm Kit provides a complete bi-wire fire detection system designed for fast installation and reliable performance.

It operates using the same bi-wire principle as the Fike Twinflex Pro system, allowing detectors, sounders, and call points to run on a single pair of cables per zone.

This makes it an ideal alternative for installers familiar with Twinflex or upgrading existing bi-wire installations.

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, giving you all essential components in one package.
Each FXN922 detector uses combined optical and heat detection to improve fire verification and reduce false alarms.

Eaton’s proven bi-wire platform provides stable, long-term performance for commercial and residential applications.

This 4-zone configuration is suitable for premises that require additional coverage areas or clearer separation between zones, such as HMOs, offices, retail units, workshops, and small industrial premises.
