Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
4.3 Power supply Praesideo is compliant.
Power supply equipment, external or included in the
VACIE, shall comply with the requirements of EN 54-4.
The network controller and all amplifiers are supplied with a
mains supply and DC backup supply (48V) input. Switch over
between the both takes place automatically, without any
interruption or status change other than the power supply
related indications.
The installer must use battery charging equipment in
accordance with EN54-4. Battery chargers must be installed in
a separate cabinet, not shared with the Praesideo system,
unless one of the following chargers is used, that are
approved for use with Praesideo:
• The PRS-48CH12 and PRS-48CHxx-DE series of 48V
battery chargers have been certified in combination
with Praesideo equipment for mounting in the same
19»»-cabinet, provided that the batteries are placed
on the ground plane of the cabinet, free from the walls.
Although not required by and therefore excluded from
EN54-4/16 certification, a battery mid-point monitor,
model SD08 from Alpha Technologies Ltd., may be
used with the PRS-48CH12 battery charger and
mounted in the Praesideo cabinet, in accordance with
the German standard VDE 0833-4.
• In addition, the Praesideo equipment can be combined
with the Merawex power supply system ZDSO400E-
AK3 in its rack. This system may consist of the main
power supply ZDSO-400-E, additional power supply
ZDSOR-400-E, additional power supply ZDSOT-400-
E, distribution panel PD-2U-x, battery circuit
resistance measurer RMB-1.
The installer must ensure that the output voltages of the
battery charger or other power supply equipment do not
exceed the specifications of the mains and battery inputs of
the connected Praesideo equipment.
Loading the 48V auxiliary output of the PRS-48CH12 and
PRS-48CHxx-DE battery chargers will reduce the maximum
available charging current for the 48V batteries and this
reduction must be taken into account when determining the
maximum battery capacity for an EN54-16 certified Praesideo
system.
The content of the EN54-16 certificate is subject to change.
The most recent version of this certificate can be found on

NOTE - The power supply may be shared with that of
the fire detection and fire alarm system.
The power supply may be shared with that of a fire detection
system, but when operated with a battery a new capacity
calculation is required.
