Where Step description Illustrations / Reference
1 AMC:S1 Connect the power supply to S1
2 All readers The factory default bus address of readers is usually 1.
In order to distinguish between readers on the same
bus, each requires a unique address.
To do this open each of the readers and set the DIP
switch (or equivalent, according to the reader’s own
documentation) for each of the 4 readers.
It is now crucial that we set the reader addresses
exactly as we will define them in the software, namely:
Main Entrance=1, Lab=2, Storeroom=3, Office=4. see
Section 3.5.3 Setting up the connection between AMC2
and the software, page 17
Tip: Write the address settings on the outside of the
readers, so that you do not mix them up later!

DELTA 1000 reader
3 AMC:S2
and both
readers
Connect the reader with address 1 (Main entrance) to
the pluggable screw terminal for connection S2 as per
the installation instructions for the chosen reader.
For instance, for the Bosch DELTA 1000 proximity
reader connect the power wires to connectors 7(+)
and 6(Ground) and the data wires to connectors
4(Data “A”) and 5 (Data “B”). As the data signal is
generated only by the voltage difference between
these wires, their order is unimportant.
To connect the reader with address 2 (Laboratory) into
this configuration (i.e. into the RS-485 bus) simply
extend the wiring from pin 7 of the first reader to pin 7
of the next, and so on.

4 AMC:S3 Connect the REX unit to S3. In our example we use a
DS150 PIR (passive infrared) motion detector. As this
is the main entrance the customer may prefer instead
to connect a simple push button here, to be operated
by the receptionist from her desk.
Documentation included with the
REX unit.
5 AMC:S4 Connect the MC (magnetic contact) unit to S4. Note: in
this example we use only the power wires. Any tamper
detection wires can be left unconnected.
Documentation included with the
MC unit.
6 AMC:S5 Connect the door opener to the relay output S5.
IMPORTANT: Make sure a protective diode is included
in parallel, see Section 3.4 Connecting the peripheral
components to the wiring, page 11
Documentation included with the
door opener unit.
7 AMC:S7 Connect S7 (the second RS-485 reader connector)
analogously to S2 above. Use the readers whose
addresses you set to 3 (Storeroom) and 4 (Office)
above.
