3 Introduction

3.1 Description of the AMC2 4W

The AMC2 4W (also called AMC2 or controller) is equipped
with four independent interfaces for Wiegand type readers. It
is able to control two doors with a reader in each direction and
up to four doors with a reader in one direction only.

Figure 3.1 The Access Modular Controller AMC2 4W

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 AMC2 electronics are completely covered by a plastic
housing. The liquid crystal display provides all important status
information.
Using the AMC2 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 paying extra money.

AMC2 4W Introduction | en 13

Figure 3.2 The AMC2 4W in a four door safety lock

The AMC2 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 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 outputs on board are not enough to
configure the system, up to three additional extensions (AMC2
8I-8O-EXT, AMC2 16I-EXT, or AMC2 16I-16O-EXT) can be
connected. The extensions offer 8 or 16 additional inputs and
outputs.
The setup procedure for an AMC2 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 using
the Device Editor (Access Engine) of the BIS Configuration
Browser or the Configurator (Access PE) to choose every free
contact of the controller or a connected extension.

5.4 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 5.4 Closing the case

NOTICE!

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.

5.5 Cabling

WARNING!

The cables used in the AMC2 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.

5.5.1 Conductor data

With the calculation below you can find out which cable type
must be used. If you connect the power supply and the AMC­device 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.
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 U

Drop

= 2V

i.e. RAWG18 (acc. specs) = 6.385 or 20,948

U

= 20,948 x 0.1 km x 1A = 2.1V

Drop

U

= 6.385 x 328 ft x 1A = 2.1V

Drop

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 Table 5.3

5.6 Grounding and Shielding

The main grounding point at the AMC2 is connected to pin 2 of
the power supply connector - see Table 7.3.
It is good practice to shield all wires carrying low level signals.

The AMC2 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.

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.

WARNING!

Please ensure that no ground loops are formed.

5.11 DIL switch selector

DIL switches are used to configure the host settings. The first
four DIL switches for address selection define the RS-485
address of the AMC2 in a RS-485 bus system. Switch 5 selects
one of the two different protocols, SDEB and BPA (according to
DIN6619). Switch 6 sets the connection to the host system to
either RS-232 or RS-485.

NOTICE!

If using an Ethernet connection, set switch 1 to ON (= factory
setting).
If using an RS-232 connection, set the address by configuring it
in the Access Control System (ACE Device Editor or Access PE
Configurator). This is a point-to-point connection that is usually
configured as address 1, so set switch 1 to ON.
