The Protec 9000/BC8 power supply is a self-contained supply designed to provide 24V dc control panel and charge associated batteries simultaneously.

The charger uses power factor correction to ensure a near-unity power factor, and switch-mode technology to provide a lightweight and efficient unit. The design of the charger is such that mains must first be applied to the unit before the batteries will be capable of supplying the load. As such, if batteries only are connected to the charger, there will be no output at the load terminals until the mains is applied. The 9000/BC8 power supply is also compatible with the Protec range of fire alarm control panels and EVC40 disabled refuge/fire telephone system.
