4. Access control modules
The access control modules are to be connected to the two RS-485 buses provided on the
ACCO-NT control panel board. Altogether, 255 controllers can be connected. Up to 128
devices can be connected to one bus. It is recommended that both buses be evenly loaded.
Firmware version 3.00 or newer of the access control module is required.
The access control modules can only be configured using a computer with ACCO Soft
program installed.
For description of the electronics boards of ACCO access control modules and the
methods of their installation, refer to the manuals delivered with respective devices.
5. Expansion modules
The modules connectable to the expander bus make it possible to increase the number of
available inputs and outputs. They also expand the access control system by adding extra
functionality.
INT-RX-S. 433 MHz keyfobs receiver expansion module. Enables operation of the access
control system using the 433 MHz keyfobs.
INT-E. Input expander. Adds 8 programmable hardwired inputs (NO, NC) to the system.
INT-O. Output expander. Adds 8 programmable hardwired outputs to the system.
INT-PP. Input/output expander. Adds 8 programmable hardwired inputs (NO, NC) and 8
programmable hardwired outputs (4 relay and 4 OC type) to the system.
INT-IORS. Input/output expander. Adds 8 programmable hardwired inputs (NO, NC) and 8
programmable relay outputs to the system.
INT-ORS. Output expander. Adds 8 programmable relay outputs to the system.
The expansion modules can only be configured by means of a computer with ACCO
Soft program installed.
For description of the electronics boards of expansion modules and the methods of
their installation, refer to the manuals delivered with respective devices.
6. Installation of the system
Disconnect power before making any electrical connections.
The following tools will be useful during installation:
blade screwdriver 2.5 mm,
Phillips screwdriver,
precision pliers,
flat nose pliers,

8 ACCO-NT SATEL
driller c/w a set of drill bits.
6.1 Installation plan
Installation should be preceded by preparation of a plan of the access control system. It is
advisable to draw a sketch of the building, showing lay-out of all devices to be included in the
system, i.e. control panel, access control modules, terminals, activators, door sensors,
expansion modules, detectors, signaling devices, etc.
6.2 Estimation of the system current consumption
At the stage of planning the access control system, you should sum up all the currents
consumed by all devices included in the system (control panel mainboard, access control
modules, expanders, etc.). The calculation must also include the current for charging the
battery connected to the power supply unit. If the sum of currents exceeds the current output
of the power supply connected to the control panel, an additional power supply unit must be
used in the system.
The sum of currents consumed by devices connected to the additional power supply must not
exceed its current output.
When planning connection of devices to individual supply outputs (control panel, access
control modules, etc.), you should bear in mind that the sum of currents consumed by those
devices must not exceed the maximum current-carrying capacity of these outputs.
Current-carrying capacity of the +EX supply output on control panel mainboard
is 0.5 A, and that of the AUX outputs is 0.5 A in total.
6.3 Cabling
For the RS-485 communication bus, use the twisted-pair type of cable (e.g. UTP –
unscreened twisted-pair cable).
To make connections between the control panel and the devices connected to the expander
bus, it is advisable to use the unshielded non-twisted cable (using the twisted-pair type of
cable, e.g. UTP, STP, FTP, is not recommendable).
Select cross-section of the power supply wires so that the supply voltage drop between the
power supply and the supplied device should not exceed 1 V as against the output voltage.
In order to guarantee correct functioning of the system components it is important that
resistance and capacitance of the signal wires be as low as possible. When the distances
between the devices are greater, several wires connected in parallel may have to be used for
each signal, in order to reduce conductor resistance. This, however, may lead in
consequence to an increase in conductor capacitance. Too high resistance or capacitance of
the cables connecting the control panel to expansion modules can prevent the devices from
working correctly. When selecting the length of cables, follow recommendations set out in
sections on connection of particular types of devices.
When making the cabling, remember that there must be sufficient distance between the low-
voltage wires and the 230 V AC power supply wires. Avoid running the signal cables in
parallel to and in close proximity of the 230 V AC supply cables.
6.4 Installing the control panel mainboard
The control panel mainboard contains electronic components sensitive to
electric charges.

SATEL ACCO-NT 9
Prior to connecting the power supply to the mainboard, complete all work
related to the installation of devices (connecting the access control modules,
expansion modules, etc.).
The control panel should be installed indoors, in spaces with normal air humidity. The control
panel must be protected against unauthorized access.
A 230 V AC power supply circuit with protective grounding must be available at the control
panel installation place.
6.5 Connecting the access control modules to RS-485 bus
To connect each of the RS-485 buses, two pairs of conductors from one cable are
used (one to connect the COM terminals, the other to connect the A RS485 B
terminals).
The length of one RS-485 bus can be up to 1200 m.
In total, up to 255 modules can be connected to the two buses (127 to one of them,
and 128 to the other one).
The access control modules should be power supplied as per description contained in
the manuals delivered with respective devices.
The access control modules should be connected to the ACCO-NT control panel using the
bus topology (using the “star” topology is not recommended). The RS-485 bus structure is
shown in Fig. 2.
6.5.1 Addressing the access control modules
When connecting the modules to the buses, keep in mind that they must have their individual
address set. The address must not be repeated even for devices connected to different
buses! Address 0 must never be set in any module.
6.5.2 Connecting the devices interacting with access control modules
The access control modules perform their functions in conjunction with:
user identification devices (LCD keypads, keypads, proximity card / iButton readers),
controlled door activating devices (electromagnetic locks, gate controllers, turnstiles, etc.),
door status control sensors.
For how they are to be connected, refer to the manual delivered with the ACCO access
control module.

10 ACCO-NT SATEL
Fig. 2. Diagram showing how the access control modules are connected to the ACCO-NT
control panel. The control panel can be connected to the bus at any point. Place 100 Ω(±
10%) resistors at the beginning and at the end of the bus. Connect the COM terminals of all
modules and control panel with an additional cable. The modules in the drawing are
designated by ordinal numbers, not addresses.
6.6 Connecting the devices to expander bus
The bus wires must be run in one cable.
The total length of expander bus must not exceed 1000 m.
The expanders should be power supplied in accordance with description contained in
the manuals delivered with respective devices.
Table 2 shows the number of conductors required for correct connection of the device to the
expander bus if 0.5 mm diameter conductors are used.

6.6.1 Addressing the devices connected to expander bus
Each device to be connected to the expander bus must have its own individual address from
the 0 to 31 range. The addresses of the devices must not repeat (the control panel does not

12 ACCO-NT SATEL
support devices having identical addresses). It is recommended that consecutive addresses
be assigned starting from 0. The address is set by means of DIP-switches.
The address affects numeration of inputs and outputs in the system (see section
“Numeration of inputs and outputs in the system”).
6.7 Connecting the devices to control panel and expander inputs
Devices must be connected to inputs in a manner which suits wiring type selected for the
given input (see: ACCO Soft manual). The inputs on control panel mainboard and the inputs
on expander boards support the following wiring types:
NO – dedicated to connecting devices with the NO (normally open) alarm output.
NC – dedicated to connecting devices with the NC (normally closed) alarm output.
According to output – do not connect devices to this input. The input status depends solely
on the status of selected output (the output is not to be physically connected with the
input).
6.8 Connecting to the Ethernet network
The device is designed to be used only in the local area networks (LAN). It must
not be connected directly to the public computer network (MAN, WAN). For
establishing connection with public networks, use a router or xDSL modem.
Connect Ethernet cable to the RJ-45 port on control panel electronics board. Use a 100Base-
TX standard compliant cable (identical to that used for connecting computers to the network).
6.9 Connecting the power supply
Do not connect power supply untill the installation work is completed.
The APS-412 power supply unit, manufactured by Satel, is required to power the ACCO-NT
control panel. For description of the power supply installation, please refer to the manual
delivered with the device.
6.9.1 Control panel power-up / start-up procedure
1. Connect the power supply unit to the dedicated socket on control panel electronics board.
2. Turn on 230 V AC supply in the circuit to which the power supply unit is connected. The
control panel will start up.
If it is necessary to power off the control panel, turn off the power supply unit.
7. Numeration of inputs and outputs in the system
Inputs and outputs are given numbers in the following way:
inputs and outputs on the control panel electronics board have numbers from 1 to 8.
the numbers of inputs and outputs in expanders depend on the expander address in the
system (inputs in expander with a lower address will be given lower numbers than the
inputs in expander with a higher address e.g. if the INT-E expanders with addresses 0 and
1 are connected to the control panel, the inputs in INT-E expander with address 0 will have
numbers from 9 to 16; the inputs in INT-E expander with address 1 will have numbers from
17 to 24, etc.).

9. About ACCO NET system operation
All components of the system are working properly, when communication is ensured between
the devices as well as between the ACCO-NT control panels and the ACCO Server program.
The ACCO Server program is used as an intermediate for communication between the
access control panels, on the one hand, and the database and ACCO Soft and ACCO-WEB
programs, on the other hand. The database stores the system configuration settings and the

16 ACCO-NT SATEL
event log. The ACCO Soft program enables configuration of the system, and the ACCO WEB
is used for management and supervision of the system.
The access control panels decide whether the user will be granted access or not. This means
that loss of communication between the ACCO-NT control panel and the ACCO Server
program will not affect functioning of the access control. However, if there is no
communication, configuration, management and supervision of the system will be impossible.
If communication with the control panel is lost:
in ACCO Soft program:
– system settings cannot be written to the control panel,,
– there is no real-time information about the status of connected devices,
in ACCO-WEB program:
– you cannot view the current events.
If communication between the access control module and the control panel is lost, the
module will be working in offline mode. Access to the door supervised by this module will be
granted only to part of the users (1024 users registered in the module). The module will
recognize the user code and the first of the cards / iButtons. When making decision to grant
access, the module will not take into consideration the access calendars, subdivision into
zones, or “Anti-Passback” feature. Only the inputs and outputs of access control module will
be able to control operation of the given module (status of the other inputs and outputs in the
system will have no effect on the module operation).
The access control modules will enter the offline mode also during remote firmware
update of the module connected to the same ACCO-NT control panel.
10. Control panel firmware update
10.1 Local update of the control panel firmware
On the www.satel.eu website, you can find the latest version of ACCO-NT control panel
firmware and the program for updating control panel firmware. In order to replace the
firmware:
1. Connect the USB MINI-B port on control panel electronics board with the computer USB
port by means of a suitable cable.
2. Run the update program for control panel firmware. A window will open with information on
the available version of control panel firmware and the MAC address of the connected
device (if only one control panel is connected to the computer).
