1.2 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.
!
Warning!
Risk of explosion of Lithium battery
The battery can explode if it is replaced incorrectly.
Replace only with the same type as recommended by the manufacturer.
Dispose used batteries according to the battery manufacturer’s 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.
Rules and Conditions
There are no specific requirements as for selling and delivery. As for storage and safe
operation, the environmental temperature should not exceed the range of 0°C to 50°C.
Disposal
Your Bosch product is designed and manufactured with high-quality materials and
components which can be recycled and reused.
This symbol means that electrical and electronic equipment, at their end-of-life, should be
disposed of separately from your household waste.

3 Introduction
3.1 Description
The APC-AMC2-4R4CF (also called AMC2-4R4, AMC2, or controller) is equipped with four
independent interfaces for RS-485 type readers. It is able to control up to 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.

3Lithium 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.
