3 Introduction
3.1 Description
The controller has four independent interfaces for RS-485 type readers. It can control a
maximum of four doors with a reader in each direction and a maximum of eight doors with a
reader in one direction only.
Figure3.1: Access Modular Controller
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 electronics of the controller are completely covered by a plastic housing. The LCD (liquid
crystal display) provides all important status information.

The controller can communicate upstream to the host computer using one of the following
interfaces:
– Ethernet
– RS-485 multi-dropped, not supported by:
– BIS 4.9.1 and later
– AMS 4.0 and later.
The controller has eight analog input devices and eight relay outputs. With its analog input
devices, the controller verifies, for example, if a lock is closed or open. The relay outputs can
be used, for example, 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 the board are not enough to configure the system, up to three additional extension boards
can be connected. The extensions offer 8 or 16 additional inputs and outputs.
In the Bosch Access Host Systems, the setup procedure for a controller 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.

4 Communication and power supply
In the communication chain of a system, the access controller is integrated between the host
system and the peripheral devices.
It is possible to connect a maximum of eight readers to the access modular controller.
The four reader interfaces are divided into two physical buses. Interface 1 and 2 are on one
bus, and interfaces 3 and 4 are on the other bus. This gives the advantage in cabling: longer
cable lengths can be used (1200m maximum per bus). Internally the buses are processed as
one interface. With this arrangement, you can connect all readers to one interface.

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 case
i
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.

Bosch Security Systems B.V. Installation manual 2022-03 | V03 |
4.5 Cabling
i
Notice!
Risk of malfunction
The cables used in the controller 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 powering the controller
With the calculation below you can find out which cable type must be used. If you connect the
power supply and the controller 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 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
Critical condition! Install the power supply closer to the controller.
i
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.

2022-03 | V03 | Installation manual Bosch Security Systems B.V.
4.6 Grounding and shielding
The main grounding point at the controller is connected to pin 2 of the power supply
connector.
For more information on these connections, refer to Connecting diagrams, page 45 .
It is good practice to shield all wires carrying low level signals.
The 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.
i
Notice!
Risk of malfunction
Ensure that no ground loops are formed.
i
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.

4.7 Connecting the power supply to the controller
Connect the power supply to the POWER 7-pin pluggable screw connector.
Figure4.8: Location of the power supply connector
Connect an external power supply (10 VDC - 30 VDC) to the controller at pin 1 (positive) and
pin 3 (0V) of the pluggable screw connector.
Bosch recommends using the Bosch APS-PSU-60 power supply unit.
This power supply can also be used as an uninterpretable power supply (UPS) when using the
appropriate batteries. It also has relay outputs for monitoring the power good signals. These
can be connect to
– pin 4 and 7 for power good AC
– pin 5 and 7 for power good Battery
– pin 6 and 7 for power good DC
If the recommended power supply is not in use, it is useful to have these pins short-circuit.
i
Notice!
If a battery is used, the power supply unit (PSU) checks the battery status every 5 minutes.
During the self-test, the PSU switches its output from AC regulated power to battery
regulated power. This causes the AMC to be supplied by the battery only.
Make sure that the battery is maintained according to the advice of the manufacturer, in order
to reduce the risk of losing the power on the AMC controller during self-test.
The duration of this self-test is of approximately 1 second.
The Power Good AC signal is switched off during the self-test.
If no battery is connected, the PSU does not perform any self-test.
Depending on the security level of your building, it is recommended to replace the battery
more frequently (e.g. every 3 years, in order to keep the system running properly).
i
Notice!
Unstable AC networks can result in various error messages on the host system. If this
happens, the AMC only reports AC power losses of more than 10 minutes of duration. This
time cannot be set.
