2.2 Safety Precautions
WARNING!
Read instructions!
Before working with the AMC2 device, read these instructions
carefully. Make sure you have understood all information
described in this document.
WARNING!
Risk of electric shock!
External power supplies must be installed and put into service
by qualified personnel. Compliance with the relevant
regulations must be ensured.
WARNING!
Risk of damage to equipment!
– Always switch off power of the AMC2 device before
modifying the installation.
– Do not connect or disconnect plug connectors, data cables
or screw connectors while power is on!
WARNING!
Health and Safety!
Installation of the AMC2 device must comply with any local fire,
health and safety regulations. A secured door that may be part
of an escape route from an area must be installed with:
– A fail-safe lock (A). So that the door will be released if
power fails. Ideally, a magnetic lock should be used.
– A normally-closed break-glass or manual pull (B) in the lock
supply wiring, so that in an emergency the fail-safe lock
can be immediately powered down.
WARNING!
You must ground the controller. Disconnect both AC and
battery power supply before working on the controller.

WARNING!
Risk of damage!
Protect the hardware from electrostatic discharge by observing
ESD instructions before unpacking or touching connectors or
electronics.
WARNING!
Lithium Battery
Danger of explosion if battery is replaced incorrectly. Replace
only with the same type as recommended by the manufacturer.
Dispose used batteries according to the battery manufacturer’s
instructions.
2.3 Unpacking
Check the packaging for visible damage. If anything has been
damaged during transport, please inform the transport agency.
Unpack the unit carefully. This is an electronic device that must
be handled with care to avoid damage. Do not attempt to put
the unit into operation if components are damaged.
If any parts are missing, inform your customer service
representative or a Bosch Security Systems salesperson. The
shipping carton is the safest transport container for the unit.
Store it and the other packaging material for future use. If the
unit has to be sent back, use the original packaging.

3 Introduction
3.1 Description of the AMC2 DCUA
The AMC2 DCUA (also called AMC2 or controller) access
control unit provides complete access control for a single
entrance. Two card readers (or keyboard card readers) can be
connected and controlled via the two Wiegand/Omron
interfaces plus up to two readers via the RS485 interface and
one via the RS232 interface.
The RS232 interface here is not used for simple access control
readers, but rather for supplementary identification methods
such as biometric (finger print, iris scan) scanners or longrange readers.
Figure 3.1 The Access Modular Controller AMC2 DCUA
All necessary information for access verification is stored in a
battery buffered on-board memory and a Micro SD memory
card. This guarantees autonomous access decisions and
complete access registrations even if the management host
system is offline.
The AMC2 electronics are completely covered by a plastic
housing. The liquid crystal display provides all important status
information.

The AMC2 DCUA can be extended by a maximum of one
AMC2 4W-EXT plus a maximum of three I/O extension modules.
The I/O extension modules AMC2 8I-8O-EXT, AMC2 16I-16OEXT, or AMC2 16I-EXT (in any combination) are, like the
AMC2 4W-EXT, connected via the AMC2 DCUA’s extension
interface. As the extension modules contain neither memory
nor display they are controlled and monitored entirely by the
AMC2 DCUA.
The signal settings and parametrization of the readers
connected to the extension module, are carried out by the
AMC2 DCUA to which it belongs.
The AMC2 DCUA communicates with the host system primarily
by ethernet. In special configurations the RS485 interface can
also be used for the host connection.
NOTICE!
The RS485 interface can be used either for the host connection
or to connect extension boards. If extension boards are used
then the host connection must be by ethernet.
The AMC2 DCUA possesses six analog inputs and six relay
outputs. It receives state information about the entrance via the
inputs and transmits door control signals and/or notifications
to external monitoring systems via the outputs. If the six inputs
and six outputs of the AMC2 DCUA are not sufficient then up to
3 extensions (AMC2 8I-8O-EXT, AMC2 16I-16O-EXT or AMC2
16I-EXT) with 8 or 16 inputs and outputs respectively can be
connected.
NOTICE!
This controller is currently a project version. In future product
software up to three extensions will be connectable in Access
Engine, and one in Access PE.
The allocation of the signals is determined by "door models"
which, when selected, reserve the necessary reader
connections and contacts for their usage. This default
allocation can be overriden and adapted to circumstances using
the parameterization tools in the access control system, where
| V 1.4 | 2010.01 Installation manual Bosch Sicherheitssysteme GmbH
AMC2 DCUA Introduction | en 13
any free contact can have a signal allocated.

Ethernet. A management host connection using RS-485 is also
possible.

6 = Wiegand/Omron connection
Using an AMC-MUX interface extension on RS485 host
connections it is possible to connect up to eight controllers to a
single COM port. Up to 200 AMCs can be connected using the
ethernet host connection.
NOTICE!
If the host connection is via ethernet then the RS485 interface
can be used for extension boards.
Using reader interfaces, up to two RS-485 and two Wiegand/
Omron devices can be connected to each AMC2 DCUA. The
RS232 interface can be used for additional input devices such
as biometric readers or long-range readers. The RS-232 and
Wiegand/Omron interfaces.
The extension interface supports up to three additional I/O
boards (AMC2 8I-8O-EXT, AMC2 16I-EXT, or AMC2 16I-16O-EXT)
