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.

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.
Figure3.1: 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.
Figure3.2: The AMC2-4R4 in a four door safety lock
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.

suggest to replace the battery every 8 years. Spare part: VARTA CR 2032 PCB.

Notice!
If an external power supply is used, this should also guarantee an uninterruptable power
supply (UPS). Example: Bosch power supply APS-PSU-60 (F.01U.282.970).
3.4 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.
Figure3.7: System overview
1 = Host
2 = AMC2-4R4
3 = Card reader (1 - 8)
4 = Communication and power supply
5 = Ethernet
System configurations for Access Control applications.
– The minimum configuration consists of:
– one PC with system software,
– one AMC2 controller,
– one AMC 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.

4 Installing
4.1 Mounting
The AMC2-4R4 can be attached on a standard 35mm (1.377in.) mounting rail using a snap-in
mechanism. Attach the AMC2-4R4 into the upper edge of the mounting rail [1], then push
down the device and snap it onto the rail by pushing it towards the back [2].
Figure4.1: Mounting the AMC2 on a mounting rail
14 en | Installing AMC2 Modular Controller
2018-02 | AMC2-4R4 | Installation Manual Bosch Access Systems GmbH
4.2 Unmounting
Notice!
To remove the AMC2-4R4 from a mounting rail, first remove all pluggable connectors.
Push down the AMC2-4R4 until the lower edge snaps out of the mounting rail [1]. Pull the
lower end of the AMC2-4R4 from the mounting rail [2].
Figure4.2: Unmounting the AMC2 from a mounting rail
AMC2 Modular Controller Installing | en 15
Bosch Access Systems GmbH Installation Manual 2018-02 | AMC2-4R4 |
4.3 Opening the Case
Notice!
To open the AMC2-4R4, first remove all pluggable connectors.
The AMC2-4R4 case consists of a top cover mounted with a two-point snap-in closure on a
chassis. To open the case, push down the two snap-ins with a screwdriver, then swing the
cover down.
Figure4.3: Opening the AMC2 case
16 en | Installing AMC2 Modular Controller
2018-02 | AMC2-4R4 | Installation Manual Bosch Access Systems GmbH
4.4 Closing the Case
Before aligning the covers, unplug any pluggable screw connectors. Insert the hooks on the
lower edge of the front cover into the lugs on lower edge of the plastic back cover [1]. Please
ensure that the BOSCH logo is not upside-down. The upper edge of the front cover now aligns
with the two-point snap-in closures on the upper edge of the back cover [2], and may thus be
clicked gently into place.
Hence the closing process is the reverse of the opening process.
Figure4.4: Closing the case
Notice!
Risk of damage to equipment
If excessive force is required to close the front cover then it is probably incorrectly hooked
into the back cover. In such cases the display ’Dialog’ button in the front cover will be
misaligned and will not function correctly.
4.5 Cabling
Notice!
Risk of malfunction
The cables used in the AMC2-4R4 access control system are not prone to electrical
interference. However, you should avoid routing cables close to heavy load switching cables
and equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft)
to reduce interference.
4.5.1 Conductor data for power to AMC2
With the calculation below you can find out which cable type must be used. If you connect the
power supply and the AMC-device with the delivered cable set from the enclosure the
calculation is not necessary.
For distances below 25m (75ft) use AWG18 conductors (1mm²). For longer distances, install
an additional power supply close to the AMC2 controller.
Please, calculate the voltage drop by checking the conductor specifications for characteristic
resistance values. The voltage drop shall not exceed 2V.
