Fire Detection - Addressable
9000/BC8 Power Supplies
• Self Contained Supply
• Deep Discharge Battery Protection
• Lightweight & Efficient Unit
• Switch Mode Technology
• Power Factor Corrected
• Designed to Power Protec Range of
Control Panels
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.
