u Intelligent access manager for one to eight

entrances

u Four interfaces include the reader power supply

u Standard 2 GB compact flash

The AMC2 (Access Modular Controller) is used as an
access controller in the access control systems ACE
(ACCESS ENGINE) from version 2.0 onward, Access
Personal Edition, and Access Professional Edition. The
device controls a group of one to eight access points.
These access points, also known as entrances, mainly
consist of doors, gates, barriers, turn stiles, revolving
doors, mantraps, ID card readers, door opening
elements and sensors. The AMC2 can control up to
eight ID card readers (depending on the reader type)
and is designed for fully processing the access logic at
the assigned entrances.
Status checks can be carried out using the eight
analog inputs. The eight relay outputs are used to
activate the door opening elements and/or generate
the security activation and signaling. The AMC2 stores
all necessary information in a battery-buffered memory
and a compact flash storage element so that, even
when the unit is offline, it is able to carry out
independent authorization checks on access points,
take access decisions, control closing/opening
elements and register movement events.

System overview

1 = Host computer
2 = AMC2
3 = Card reader
4 = Communication and power supply
As shown in the diagram, the AMC2 is integrated
between the host system (e.g. Access Engine) and the
peripheral devices.
They are connected to the host system via RS485,
RS232 (e.g. modem operation) or Ethernet, depending
on the size of the system. The relevant host interface
is selected during installation. All three interfaces are

available on the device by default. With RS485
operation, a maximum of eight AMC2’s can be
connected to one party line.
There are up to four slots on the peripheral bus for
readers, including the slot for the power supply.

Host connections

RS232 host interfaces

The Access Engine application administers up to 32
serial direct connections (ports), theoretically allowing
32 AMC2’s to be directly connected in series.

Notice

Since PCs only have a maximum of two COM
interfaces by default, the following connection
variants are preferable for configurations with
more than two AMC2’s:

Installation/configuration notes

Power supply

An external power supply (10 to 30 V DC) for the
AMC2 is connected to the first (positive) and third pin
(negative).
When using an uninterruptible power supply (UPS),
the relevant UPS output relay is connected to the pins

• 4 and 7 for alternating current

• 5 and 7 for the battery

• 6 and 7 for direct current

Otherwise, these pins will short-circuit.

2 = RS232/485 AMC-MUX converter
3 = AMC2
4a = RS232 connection
4b = RS485 connection: Up to eight AMC2’s can be
connected to one RS485 interface for each AMC-MUX.
The AMC-MUX interface converter should be used if
more than two AMC2’s are connected.
The interface converter generates an RS485 bus (2 or
4-wire) from a COM port and thus allows up to eight
AMC2’s to be connected with the RS485-typical
distances (1200 m/3900 ft.).
