2020-01 | V02 | Installation manual Bosch Access Systems B.V.
3 Introduction
3.1 Description
The extension module AMC2-4WE is equipped with four Wiegand type reader-interfaces plus
eight inputs and eight outputs. Hence with the AMC2-4WE it is possible to double the number
of readers on an AMC2-4W from 4 to 8.
Figure3.1: The extension module AMC2-4WE
The AMC2-4WE can not be deployed as an independent controller but only as an extension
module for the AMC2-4W. Control and access decisions and bookings are carried out by the
AMC2-4W alone.
Notice!
The AMC2-4WE can only be used with AMC2-4W. As it provides Wiegand interfaces it cannot
be coupled with an AMC2-4R4.
The AMC2-4W can be extended by a maximum of one AMC2-4WE plus a maximum of three I/O
extension modules. The I/O extension modules AMC2-8IOEAMC2-16IOE (in any combination)
are, like the AMC2-4WE, connected via the AMC2-4W’s extension interface.
Notice!
The AMC2-4WE has no display. The information about the input and outputs will be shown on
special pages of the AMC2 display.
As the extension modules contain neither memory nor display they are controlled and
monitored entirely by the AMC2-4W.
The AMC2-4W can have an additional interface extension module AMC2-4WE, so that the
number of inputs and outputs can grow up to 64.
Notice!
An AMC2-4WE provides signals only to the AMC2 to which it is connected. Signal transfer to
another AMC2 is not possible.
The signal settings and parametrization of the readers connected to the extension module, are
carried out by the configuration applications in the access control system and by the
AMC2-4W to which it belongs.

Access Modular Controller 2 Introduction | en 11
Bosch Access Systems B.V. Installation manual 2020-01 | V02 |
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,
– Each AMC2-4W controller can be extended with an AMC2-4WE extension module.
The using of AMC2-4WE modules has no influence on the limit of the maximum of controllers
in one system, because it is an extension to an AMC2-4W and not a controller.
Using Wiegand reader interfaces, up to four peripheral devices can be connected to each
AMC2-4R4. The interfaces are point-to-point connections, meaning that only one reader can be
connected to one interface.

4 Installing
Notice!
To build an UL approved system refer the documentation contained in the folder titled "_UL"
on the delivered CD.
4.1 Mounting
The AMC2-4R4 can be attached on a standard 35mm (1.377in.) 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].
Figure4.1: Mounting the AMC2 device on a mounting rail

Access Modular Controller 2 Installing | en 13
Bosch Access Systems B.V. Installation manual 2020-01 | V02 |
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].
Figure4.2: Unmounting the AMC2 device from a mounting rail

2020-01 | V02 | Installation manual Bosch Access Systems B.V.
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.
Figure4.3: Opening the AMC2-4WE case

Access Modular Controller 2 Installing | en 15
Bosch Access Systems B.V. Installation manual 2020-01 | V02 |
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.
Figure4.4: Closing the extension 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 25m (75ft) use AWG18 conductors (1mm²). For longer distances, install
an additional power supply close to the AMC2 controller.

16 en | Installing Access Modular Controller 2
2020-01 | V02 | Installation manual Bosch Access Systems B.V.
Please, calculate the voltage drop by checking the conductor specifications for characteristic
resistance values. The voltage drop shall not exceed 2V.
Example:
Length = 100 m/328 ft
U = 12V, I = 1A, maximum UDrop = 2V
i.e. RAWG18 (acc. specs) = 6.385 or 20,948
UDrop = 20,948 x 0.1 km x 1A = 2.1V
UDrop = 6.385 x 328 ft x 1A = 2.1V
Critical condition! Install the power supply closer to the controller.
Notice!
These specifications apply to power supply, readers, relay outputs, and extension interface.
Regarding inputs, specific voltage-drop values need to be taken into account. Refer to
Connecting Analog Input Devices, page 26.

Bosch Access Systems B.V. Installation manual 2020-01 | V02 |
4.6 Grounding and Shielding
The AMC2 controller allows you to create a central ground or shielding point, simply by setting
certain jumpers. Set these jumpers only if grounding or shielding is not achieved by other
means.
1. If the AMC2-4R4 has its own power - as in the third example in Overview - Power supply/
consumption, page 19 - the shield will be connected to pin 2 of the power supply
connector - see Connecting Diagrams, page 33.
2. If the extension module is powered from the AMC2 controller - as in the second example
in Overview - Power supply/consumption, page 19 - the connection should be made as in
the RS-485 for extension modules, page 21 diagram.
3. If more than one extension module is to be connected to an AMC2 controller, and all of
them to receive power from it as well, then use the RS-485 extension interface for the
connection.
Notice!
In the second and third case the jumper on the bottom side of the AMC2-controller must to
be set - see the installation manual of the AMC2-4W.
Notice!
Risk of malfunction
Ensure that no ground loops are formed.
Notice!
In general the following apply:
If the devices have their own power supplies, the shielding is applied to one side only. The
free end should be insulated to avoid inadvertent connections.
If one device is fed power by another, the cable shielding should be applied to both sides.
4.6.1 Grounding for Extension Interface
Figure4.5: Location of ground jumper bottom side
The jumper setting A1 shows the factory settings.
Jumper connects the internal ground of the AMC2-4R4 to the ground of the RS-485 slave
interface. Set Jumper A2 only at the first AMC2-4R4 of a party line Overview - Power supply/
consumption, page 19.

4.7 Connecting Power Supply
Notice!
The battery status is checked every 5 minutes by the power supply unit (APS-PBC-60 or APS-
PSU-60).
As the battery charging/discharging levels tend to vary, the AMC2 provides information about
the battery status every 10 minutes. This feature allows a more reliable battery status
information.
4.7.1 Direct Power Supply
Connect the power supply to the POWER 7-pin pluggable screw connector. Refer to
Connecting Diagrams, page 33 for a complete diagram.
Figure4.6: Location of the power supply connector
Connect an external power supply (10 - 30 Vdc) for AMC2-4R4 at pin 1 (positive) and pin 3 (0
V) of the pluggable screw connector.
If an uninterruptible power supply (UPS) is used, the relay output for power good signals from
the UPS is connected to the following pins:
– pin 4 and 7 for power good AC
– pin 5 and 7 for power good Battery
– pin 6 and 7 for power good DC
Otherwise these pins must be short-circuited.
4.7.2 Power Supply via RS-485 Interface
The power can also be supplied by the AMC2-4W. In this case power pins 1 and 2 should be
connected, as well as data lines on pins 3 - 6.

Tab.4.1: Overview - power supply and power consumption
Explanations for the table columns:
Output power Power provided by the power supply.
Own usage Power used by AMC2 device
Available Power remaining for external devices
Constant load Amount of the available power that can
be drawn constantly.
Hence Example 1 can be read as follows:
Of the total incoming power (60VA) 5VA will be drawn by the
AMC2 itself . This leaves 55VA to support external devices.
25VA of these 55VA can be used for constant load (e.g. a card
reader) leaving 30VA for occasional peak usage (e.g. a door
opener).
