Notice!
Some features and functions described in this document depend on the firmware loaded into
the device and host software. Make sure that the controller is updated to the firmware
version provided with the host system.
This product is RoHS compliant. See Technical data for the full table of hazardous
components.
1.1 Unpacking
Check the packaging for visible damage. If anything has been damaged during transport,
please inform the transport agency.
Unpack the product carefully. This is an electronic device that must be handled with care to
avoid damage. Do not attempt to put the product 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
the shipping carton and the other packaging material for future use. If the product has to be
sent back, use the original packaging.
1.2 FCC compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause
undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC rules. The limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
1. Reorient or relocate receiving antenna.
2. Increase the separation between the equipment and the receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.

Bosch Security Systems B.V. Installation manual 2022-03 | V03 |
2 Short information
The AMC2 can control a maximum of eight ID readers (depending on the reader type) and fully
processes the access logic at the assigned entrances.
The device controls a group of one to eight access points. These access points, also known as
entrances, can be:
– doors
– gates
– barriers
– turn stiles
– revolving doors
– mantraps
– ID card, PIN and biometric readers
– door opening elements
– sensors.
All the product versions use encrypted connections between the access modular controller
and the host system.
The controller stores all necessary information in a battery-buffered memory and in a compact
flash storage element. Even when the unit is offline, it is able to perform:
– Independent status and authorization checks on access points
– Take access decisions
– Activate and deactivate connected peripheral elements
– Detect and register all relevant events
The Access Modular Controller (AMC) is supported by the Access Professional Edition (APE),
BIS Access Engine (ACE) and the Access Management System (AMS).

3 Introduction
3.1 Description
The controller has four independent interfaces for RS-485 type readers. It can control a
maximum of four doors with a reader in each direction and a maximum of eight doors with a
reader in one direction only.
Figure3.1: Access Modular Controller
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 adapter provides adequate storage capability for cardholders and
events.
The electronics of the controller are completely covered by a plastic housing. The LCD (liquid
crystal display) provides all important status information.

Bosch Security Systems B.V. Installation manual 2022-03 | V03 |
The controller can communicate upstream to the host computer using one of the following
interfaces:
– Ethernet
– RS-485 multi-dropped, not supported by:
– BIS 4.9.1 and later
– AMS 4.0 and later.
The controller has eight analog input devices and eight relay outputs. With its analog input
devices, the controller verifies, for example, if a lock is closed or open. The relay outputs can
be used, for example, 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 the board are not enough to configure the system, up to three additional extension boards
can be connected. The extensions offer 8 or 16 additional inputs and outputs.
In the Bosch Access Host Systems, the setup procedure for a controller 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.

2 Lithium battery for buffering of static RAM and real time clock (RTC). The battery life
is estimated at 10 years, nevertheless an error message is generated if the voltage
sinks below a preset minimum level.
NOTICE: In order to avoid an error message caused by an earlier voltage drop we
suggest to replace the battery every 8 years. Spare part: VARTA CR 2032 PCB.
