Power supply and batteries
The external AC 230 V power supply unit PP2004-A1 provides DC 24 V to all the system ex-
ternally mounted call stations.
The power supply unit ensures that the externally mounted components continue to operate
without interruption in case of an 'AC 230 V' line voltage failure by providing a DC 24 V from
the emergency batteries.
The power supply unit also charges, monitors, and protects the emergency batteries. The
batteries are charged in accordance with the standard EN 54-4 based on their nominal ca-
pacity.
The power supply unit is equipped with a converter, an over-voltage protection switch, and
the battery deep discharge protection. The deep discharge protection ensures that the bat-
teries never fully discharge, thus preventing battery damage.
The power supply unit is suitable for a supply system with a nominal voltage of
230 V / 50 Hz.
Fault messages are displayed visually on the front of the unit.
Wall cabinets
The robust wall cabinet provides a space-saving and secure solution for accommodating
Cerberus PACE Compact system components, such as the audio matrix, power amplifiers,
Ethernet switches, and the power supply.
It is pre-assembled in accordance with the requirements for Cerberus PACE Compact sys-
tem components to provide maximum protection, even given tough ambient conditions.
The Cerberus PACE Compact cabinets provide an active ventilation system, to guarantee
that system components can perform their maximum functions at the specified operating
temperatures. This ensures that system components work reliably even at the limits of the
specified workload and the outside temperature.
