The EFXN520 Conventional Standard Base has been specifically designed to be compatible with the Cooper / JSB range of conventional detectors. Engineered for flexibility, simplicity, and rapid installation, this base ensures reliable performance and ease of use.
The base features purpose-designed components to provide a fault warning if the detector is removed, while maintaining full zone wiring integrity. A Schottky diode is included in series with the negative terminals to enable fault monitoring and allow the circuit to continue functioning if the detector is removed.
