Installation Instructions / ACS-8 11
3. General information
Access control systems are used where access to restricted areas is limited to authorised personnel.
Software
On the systems described here, MultiAccess for Windows or IQ MultiAccess is the governing software for
all access control devices. Access rights for personnel, actions, time orders and the transmission of the data
to the hardware can all be set up using this software.
Hardware
The ACS-Compact, ACS-1, ACS-2 and ACS-8 are the controllers that control access and together are
responsible for the overall operational functionality. After receiving their data from MultiAccess for Windows
or IQ MultiAccess, the controllers can operate in stand-alone mode. This means that the control of access
remains active without impairment even if MultiAccess for Windows or IQ MultiAccess is not running.
When starting MultiAccess for Windows or IQ Multi Access, the events that have occurred while the PC was
offline are automatically entered into the event log file.
The display panel is a device used for the indication of door states, actions and the whereabouts of
personnel.
The ethernet interface (LAN) links between the PC and the controllers and is also responsible for
antipassback control. The PC configured with IQ MultiAccess must be in operation.
When ACS-8 systems are used in simplified mode the interface converter 026817.03 can be used.
If only one ACS-8 is connected it can be directly connected using the RS 232 serial interface.
These connections can be made in various permutations.

12 Installation Instructions / ACS-8
4. Protective measures
Defence against electrostatic discharge
Modern semiconductor devices are susceptible to electrostatic charges. The higher the integration density,
the finer the structures on the chip and the greater the danger of electrostatic damage.
With some semiconductor devices, damage may be caused by less than 20V. This is a very low value when
values of greater than 1000v can be generated by walking across a carpet.
Damage caused by electrostatic discharge rarely leads to instant failure. More commonly, semiconductor
structures receiving damage from electrostatic discharges have a residual burning trace which initiates a
chemical process on the chip, causing it to degrade over a period of days, weeks, months or even years.
Partial operation can be difficult to detect until eventual failure occurs.
Protection against electrostatic charge
As electrostatic charges cannot be avoided, the electronics must be protected from dangerous voltage
levels.
- Wear an ESD wriststrap connected to the earth connection of the controller.
- Use only soldering irons that are galvanically separated from the power supply and equipped with
an electronic temperature control.
Protective measures against over-voltage transients
Protective shielding and grounding must be provided to avoid malfunctions and damage to system
components due to over-voltage. This may occur due to switching of supplies or heavy machinery on the
supply line or from direct or indirect effects of thunderstorms. (See DIN VDE 0845 part 1, Protection of
telecommunication systems against lightning strokes, static charges and over-voltages caused by power
installations – measures against over-voltages.)
Protection according to the VdS requirements is built into the products.
Protection against damage caused by lighting strokes and over-voltages can be assured by implementing
appropriate measures for internal and external lightning (medium and coarse) protection. Additional
requirements will depend on the installation location and the nature of other equipment connected to the
system.
Over-voltage caused by switching actions causes a very steep rate of change of voltage. This means that
the voltage can reach values of several kV within a few microseconds. Such voltage pulses (transients)
cause the destruction of electronic components.
Adequate over-voltage protection, will absorb these transients.
Causes of transient interference voltages
Transient voltages are often caused by atmospheric discharge, i.e. lightning stroke. A lightning discharge
may release currents reaching values over100kA with very short rise times. This current causes a high
voltage drop in the earth resistance of a building and the high rate of change of current induces high
voltages in conductive loops. The energy resulting causes the damage to unprotected devices.
Switching actions in electrical systems also cause over-voltage transients.
High-voltage power supply networks are fitted with high-frequency compensation systems and are coupled
to low-voltage parts of the network. Over-voltages and high-frequency power transients in low-voltage
installations can also be caused by sharp drops in voltage, phase control, etc. In these instances, the rate
of change of current can reach higher values than a lightning stroke.

5. Important installation instructions
(See also chapter = Safety instructions)
5.1 Grounding and shielding
Use shielded cables and a suitable shielding connection for protection against electromagnetic interference.
Make sure that the line shields in the distribution boxes are connected so that there are no links to other
potentials. In the ACS-8, all shields should be connected to one point using the shortest possible route.
The shield soldering bar serves as a common point for connection of the ground conductors and line shields
(see below).
Circuit diagram DB1 and DB2 grounding bridges:
The grounding bridges are located on the CPU board near the power supply unit connector (see chapter
15.1).
The following shielding connections can be made:
Connect the shield soldering bar to the ground conductor and keep the grounding bridges closed
With this method, the DB1 and DB2 grounding bridges provide a capacitive coupling between the ground
conductor and the system operating voltage.
This connection offers excellent protection against conducted interference and cable shield discharges.
However, this connection must only be used if PE and N are connected separately (modern grounding) and
if it is guaranteed that the ground conductor does not carry any high or low frequency signals.
Connect the shield soldering bar to the ground conductor and open the grounding bridges
In this configuration, the capacitive coupling to the system operating voltage is interrupted by the removing
the grounding bridges. This connection should be used if the ground is susceptible to interference, where
the capacitive coupling would transfer it to the ACS-8.
Connect the shield soldering bar to the incoming mains terminal
With this configuration, the shield soldering bar ust
be connected directly to the incoming mains
terminal. This method is used where the ground
conductor is heavily loaded and is the only way to
overcome interference, if there is a problem with
the previous methods described.

14 Installation Instructions / ACS-8
5.2 Shielded lines
The ACS-8 devices are daisy-chained together using shielded cables.
Use Cat 5 cables or higher.
The shielding of the incoming line connects to the shield terminal bar of the ACS-8. The shielding of the
outgoing line must not be connected.
The shield terminal bar in each ACS-8 must be connected to a separate PE.
(min. cable cross-section 1,5mm²)
When it is not possible to provide a mains earth connection at each device on a 12V system, then a three
core cable should be used to provide the 12V DC power and an earth continuity conductor.
The shielding of the reader line is connected on one side to the shield terminal bar in the ACS-8.
The above points also apply to the ACS-8 module bus.

Installation Instructions / ACS-8 17
6. ACS-8/cables
6.1 ACS-8 supply voltage
Please observe the informations about grounding and shielding in chapter 5.
6.1.1 ACS-8 230 V version
Parameter Value
operating voltage range 230 V AC –15% +10%
mains frequency 40 – 60 Hz
power supply cable type NYM 3 x 1,5 mm²
6.1.2 ACS-8 12V version
Parameter Value
operating voltage range 10.0V to 15.0V DC
current consumption depends on the reader type, the number of readers and the interface type
The door strike must be taken into consideration if its supply comes from the ACS-8. The current
consumption of a door strike depends on the type, but lies somewhere between 200mA and 500mA.
The current consumption of an energized door strike must be known for each ACS-8 when
designing a 12 V system.
The following drawing (powered on) shows the voltage drop of a 1.5mm2cable compared to a 4mm2cable.
A power consumption of 1A is calculated for each ACS-8.
Observe the outgoing and return line.

18 Installation Instructions / ACS-8
The voltage diagrams 1 and 2 compare the effects of two cable cross-sections.
The required line cross-section must be calculated using the graphs shown above .
Note! Pay attention to legal rulings!
The local requirements must be observed for the line cross-section. VDE 0100 applies to Germany.
The output fuse of the power supply unit must have the appropriate current rating. The highest
current rating is determined by the smallest line cross-section of the supply cable.

Installation Instructions / ACS-8 19
6.2 ACS-8 module bus/cables
6.2.1 Cable types for data lines
Type Length Comments
J-Y(St)Y up to 40m This cable is available with diameters of 0.6mm
and 0.8mm and various numbers of cores.
Cat-5e (or better) Up to 1200m
6.2.2 Cable types for the power supply of bus modules
-J-Y(St)Y i0.6mm, i0.8mm, depending on the calculation (see appendix/Planning
examples)
Note: The required number of wires must not be greater than the terminal diameter.
When using a single J-Y(St)Y cable to carry both the power supply of the
bus modules and the data signals, the cable length is limited to 40m since
this is the data line limit (see 6.2.1 J-Y(St)Y as data line). This must be the
case even if a longer distance was calculated for the power supply.
-NYM 5 x 1.5mm² (See appendix/Planning examples)
6.2.3 ACS-8 module bus
6.2.3.1 Power supply
There are two possible connection versions:
1. Central power supply of the ACS-8 (in the bus line or a separate line).
- All modules have their voltage supplied by the ACS-8.
- No potential separation is required.
- The maximum distance depends on the voltage drop in the cable.
2. Decentralized power supply by one or more external power supply units distributed throughout the
system.
- All modules connected to an RS 485 module bus must have potential isolators fitted.
6.2.3.2 Power supply of the modules via the bus line
The calculations of the line cross-sections for +12V DC and 0V must take the current requirements of the
connected modules into consideration. In addition, any occasional "switching current" (e.g. relay) must also
be considered.
Even in case of emergency power operation, the operating voltage must not fall below 10V DC. This means
that where the battery voltage is 10.5V DC, only a 0.5V voltage drop can be permitted.
For devices with a power supply of 12V, (without emergency power supply) a voltage drop of 2V can be
permitted.

20 Installation Instructions / ACS-8
6.2.3.3 Power supply of the modules via a separate power supply unit
Since the power supply through a bus is very limited, a separate power supply unit located near the modules
(door) must be used where larger distances or increased current consumption is required.
Each communication module has two RS 485 drivers with a separate supply.
An internal or external power supply can be used for each RS 485 driver. The supplies of the two drivers
must not be inter-connected.
External power supply units supply the potential separation module (POT) with 12V DC. Details of these can
be found in the product list.
6.2.3.4 Cable lengths and line cross-section
A maximum length of 1200m is possible for the RS 485 bus (without power supply).
Whether the +12V/0V lines are included in the bus or on a separate cable, the required cable cross-section
must be calculated.
Modules with higher current demands, require a separate line or a cable with a larger cross-section.
6.3 Line stubs (Blind spurs)
Stubs are not appropriate for use with buses and lead to data reflections (the signals bounce back) from high
impedance blind end terminations and should be avoided during installation.
If stubs cannot be avoided, they must not be greater than 3m in length and the terminating
resistor should not be connected.
6.4 Potential Isolation
The communication module has two floating RS 485 interfaces.
The 4I, 4O, 4I/2O modules are each fitted with a floating RS 485 interface.
The reader, keypad and door modules are not floating.
If potential isolation is required, up to 4 of these modules can be connected to the RS 485 bus with the
potential isolator. Each of the 4 modules can be located up to 10m from the potential isolator (POT).
6.4.1 Central power supply from the ACS-8
No potential isolation is required.
6.4.2 Decentralized power supply using several external power supply units distributed
in the system
If problems should appear with the data transmission to the ACS-8, a potential isolator (POT) should be
used.
