Safety Precautions
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.
Ensure compliance with the relevant regulations.
Ground the controller.
Disconnect both AC and battery power supply before working
on the controller.
!
Warning!
Risk of fire
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:
Install a fail-safe lock (A), so that the door will be released if
power fails. Ideally, use a magnetic lock.
Install a normally-closed break glass or a manual pull (B) in the
lock supply wiring, so that in an emergency the fail-safe lock
can be immediately powered down.

instructions.
Notice!
Risk of damage to equipment
Protect the hardware from electrostatic discharge by observing
ESD instructions before unpacking of touching connectors of
electronics.
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.
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

Introduction
Description
The AMC2-4R4 (also called AMC2 or controller) is equipped with
four independent interfaces for RS-485 type readers. It is able to
control four doors with a reader in each direction and up to
eight doors with a reader in one direction only.
Figure 3.1: The Access Modular Controller AMC2-4R4
All necessary information for access verification is stored in a
battery buffered on-board memory and a Compact Flash (CF)
memory card. This guarantees autonomous access decisions and
complete access registrations even if the management host
system is offline. The built in compact flash card provides
adequate storage capability for cardholders and events.
The AMC2-4R4 electronics are completely covered by a plastic
housing. The liquid crystal display provides all important status
information.
Using the AMC2-4R4 gives you the full functionality and the
offline capability of a complete access control system in each
room. This leads to an excellent reliability and a very high
redundancy without extra cost.

The AMC2-4R4 can communicate upstream to the host
computer using RS-485 multi‑dropped, RS-232 or 10/100 Mbit/s
Ethernet. It has eight analog input devices and eight relay
outputs. With its analog input devices, the AMC2-4R4 verifies,
for example, if a lock is closed or open. The relay outputs can be
used to activate lock mechanisms if access is granted, or
activate the burglar alarm system if an intrusion or system alert
is detected. If the eight inputs and eight outputs on board are
not enough to configure the system, up to three additional
extensions (AMC2-8IOE, AMC2-16IE, or AMC2-16IOE) can be
connected. The extensions offer 8 or 16 additional inputs and
outputs.
The setup procedure for an AMC2-4R4 is made very simple and
fast by the use of door templates. Once selected, all the inputs
and outputs are predefined. These settings can be changed to
choose every free contact of the controller or a connected
extension.

System Overview
The Access Controller AMC2-4R4 is connected between the
management host system and different peripheral devices. By
default, a management host system is connected using Ethernet.
A management host connection using RS-485 or RS-232 is also
possible. Corresponding to the available interfaces, one AMC2

can be connected to each COM port using RS-232 mode. In
RS-485 mode, up to eight access controllers can be combined
on one party line.

System configurations for Access Control applications
–The minimum configuration consists of
– one PC with system software
– one AMC2 controller
– one AMC PBC-60 power supply
– one AMC enclosure

– The maximum configuration depends on the system
software.
Using RS-485 reader interfaces, up to eight peripheral devices
can be connected to each AMC2. The four reader interfaces are
divided into two buses. Interface 1 and 2 are on one bus, and
interfaces 3 and 4 are on the other bus. With this arrangement,
you can connect all readers to one interface.
The extension interface supports up to three additional I/O
boards (AMC2-8IOE, AMC2-16IE, or AMC2-16IOE). All extension
boards are controlled by the AMC2 and are freely combinable.
