3 Introduction3.1 Description

The APC-AMC2-4R4CF (also called AMC2-4R4, AMC2, or controller) is equipped with fourindependent interfaces for RS-485 type readers. It is able to control up to four doors with areader in each direction and up to eight doors with a reader in one direction only.The APC-AMC2-4WCF (also called AMC2-4W , AMC2, or controller) is equipped with fourindependent interfaces for Wiegand type readers. It is able to control two doors with a readerin each direction and up to four doors with a reader in one direction only.The extension module AMC2-4WE is equipped with four Wiegand type reader-interfaces pluseight inputs and eight outputs. Hence with the AMC2-4WE it is possible to double the numberof readers on an AMC2-4W from 4 to 8.The AMC2-16ION board provides inputs and outputs to control doors and other componentsindependent of access control system.The extension board AMC2-16IOE can be used with an AMC2 controller. It serves additionalinputs and outputs.The AMC2-4R4 (also called AMC2 or controller) access control unit provides complete accesscontrol for a single entrance. Two card readers (or keyboard card readers) can be connectedand controlled via the two Wiegand interfaces plus up to two readers via the RS-485 interfaceand one via the RS-232 interface.The RS-232 interface here is not used for simple access control readers, but rather forsupplementary identification methods such as biometric (finger print, iris scan) scanners orlong-range readers.

All necessary information for access verification is stored in a battery buffered on-boardmemory and a Compact Flash (CF) memory card. This guarantees autonomous accessdecisions and complete access registrations even if the management host system is offline.The built in compact flash card provides adequate storage capability for cardholders andevents.

The AMC2-4W electronics are completely covered by a plastic housing. The liquid crystaldisplay provides all important status information.

Using the AMC2-4R4 gives you the full functionality and the offline capability of a completeaccess control system in each room. This leads to an excellent reliability and a very highredundancy without extra cost.The AMC2-4WE can not be deployed as an independent controller but only as an extensionmodule for the AMC2-4W. Control and access decisions and bookings are carried out by theAMC2-4W alone.

Notice!The AMC2-4WE can only be used with AMC2-4W. As it provides Wiegand interfaces it cannotbe coupled with an AMC2-4R4.

The AMC2-4W can be extended by a maximum of one AMC2-4WE plus a maximum of three I/Oextension modules. The I/O extension modules AMC2-8IOEAMC2-16IOE (in any combination)are, like the AMC2-4WE, connected via the AMC2-4W’s extension interface.



Notice!The AMC2-4WE has no display. The information about the input and outputs will be shown onspecial pages of the AMC2 display.

As the extension modules contain neither memory nor display they are controlled andmonitored entirely by the AMC2-4W.The AMC2-4W can have an additional interface extension module AMC2-4WE, so that thenumber of inputs and outputs can grow up to 64.

Notice!An AMC2-4WE provides signals only to the AMC2 to which it is connected. Signal transfer toanother AMC2 is not possible.

The signal settings and parametrization of the readers connected to the extension module, arecarried out by the configuration applications in the access control system and by theAMC2-4W to which it belongs.The AMC2-4R4 standalone board (hereafter also referred as AMC2 or controller) are deployedvia a dedicated OPC-Server. Though similar in appearance to the AMC2-4W and AMC2-4R4controllers, the AMC2-4R4 has no reader interfaces, but is intended instead for the efficientmonitoring and control of many devices, especially entrances, simultaneously. It is not anextension board like the AMC2-16IOE, AMC2-8IOE, and AMC2-16IE but possesses its own CPUand host interfaces.The AMC2-4R4 has 16 analog inputs and 16 relay outputs. Via its inputs the module candetermine the status (e.g. locked, closed or open) of entrances, windows or other devices,and its output signals can lock/unlock doors, or trigger alarms with external monitoringsystems in the case of an intrusion.If the 8 and the 8 outputs are insufficient for your needs, then up to three extensions(AMC2-16IOE , AMC2-8IOE, or AMC2-16IE) can be connected, thus providing the AMC2-4R4with a maximum of 64 inputs and 64 outputs for configuration.The AMC2 has eight analog input devices and eight relay outputs. With its analog inputdevices, the AMC2 verifies, for example, if a lock is closed or open. The relay outputs can beused to activate lock mechanisms if access is granted, or activate an external alarm system ifan intrusion or system alert is detected.If the eight inputs and eight outputs of the AMC2 are not enough to configure the system up tothree additional extensions AMC2-16IOE can be connected. The extension offers 16 additionalinputs and outputs.The AMC2-16IOE electronic is completely covered by a plastic housing.

Notice!The AMC2-16IOE has no display. The information about the input and outputs will be shownon special pages of the AMC2 display.

The AMC2-16IOE contains 16 analog inputs and 16 relay outputs. In analogy with the AMC2 itverifies if a lock is open or closed respectively activates alarms or lock mechanisms.An AMC2-4W can have an additional interface extension module AMC2-4WE, so that thenumber of inputs and outputs grow up to 64.



Notice!An AMC2-16IOE provides signals only to the AMC2 to which it is connected. Signal transfer toanother AMC2 is not possible.

Figure 3.10: Example of an entrance configuration with an AMC2-2R2

The AMC2-4R4 communicates with the host system primarily by ethernet. In specialconfigurations the RS-485 interface can also be used for the host connection.



Notice!The RS-485 interface can be used either for the host connection or to connect extensionboards. If extension boards are used then the host connection must be by ethernet.

The AMC2-4R4 possesses six analog inputs and six relay outputs. It receives state informationabout the entrance via the inputs and transmits door control signals and/or notifications toexternal monitoring systems via the outputs. If the six inputs and six outputs of the AMC2-4R4are not sufficient then up to 3 extensions (AMC2-8IOE, AMC2-16IOE or AMC2-16IE) with 8 or16 inputs and outputs respectively can be connected.

Notice!This controller is currently a project version.

The allocation of the signals is determined by "door models" which, when selected, reservethe necessary reader connections and contacts for their usage. This default allocation can beoverriden and adapted to circumstances using the parameterization tools in the access controlsystem, where any free contact can have a signal allocated.

The AMC2-4R4 can communicate upstream to the host computer using RS-485 multi‑dropped,RS-232 or 10/100 Mbit/s Ethernet. It has eight analog input devices and eight relay outputs.With its analog input devices, the AMC2-4R4 verifies, for example, if a lock is closed or open.The relay outputs can be used to activate lock mechanisms if access is granted, or activate theburglar alarm system if an intrusion or system alert is detected. If the eight inputs and eightoutputs on board are not enough to configure the system, up to three additional extensions(AMC2-8IOE, AMC2-16IE, or AMC2-16IOE) can be connected. The extensions offer 8 or 16additional inputs and outputs.The setup procedure for an AMC2-4R4 is made very simple and fast by the use of doortemplates. Once selected, all the inputs and outputs are predefined. These settings can bechanged to choose every free contact of the controller or a connected extension.

3.1.1 Extension AMC2-16IOEThe extension board AMC2-16IOE can be used with an AMC2 controller. It serves additionalinputs and outputs.

Figure 3.11: The extension board AMC2-16IOE



The AMC2 has eight analog input devices and eight relay outputs. With its analog inputdevices, the AMC2 verifies, for example, if a lock is closed or open. The relay outputs can beused to activate lock mechanisms if access is granted, or activate an external alarm system ifan intrusion or system alert is detected.The AMC2-16IOE electronics are completely covered by a plastic housing.

Notice!The AMC2-16IOE has no display. The information about the input and outputs will be shownon special pages of the AMC2 display.

Notice!An AMC2-16IOE provides signals only to the AMC2 to which it is connected. Signal transfer toanother AMC2 is not possible.

Notice!Depending on the software system up to 3 extension modules can be connected at random.

3.1.2 Extension AMC2-8IOETo optimize the utilization of the available signals the extension module can be delivered in areduced version, too. The AMC2-8IOE has eight inputs and eight outputs. The places of thepluggable screw connectors are on one side of the module - the other side will be closed bythe housing.

Figure 3.12: Extension module AMC2 8IOE

Notice!The AMC2-8IOE is identical in all respects to the AMC2-16IOE except in the number of inputsand outputs. Information in this manual refers to all three extensions described here, unlessexplicitly stated otherwise.



3.1.3 Extension AMC2-16IEAnother variant of the extension modul AMC2-16IOE is the AMC2-16IE which offers connectorsfor input signals only.The inputs are located at the same positions as on the AMC2-16IOE. The output connectionsin the AMC2-16IE are not usable. Within a system configuration the AMC2-16IE is treated as anormal extension module:It can be connected at any AMC2. Up to three extensions (for BIS three, for Access PE onlyone) can be connected to an AMC2. Extension variants can be used in any combination.

Figure 3.13: Extension module AMC2-16IE

Notice!The AMC2-16IE is identical in all respects to the AMC2-16IOE except in missing outputs.Information in this manual refers to all three extensions described here, unless explicitlystated otherwise.

3.4 System OverviewThe Access Controller AMC2-4R4 is connected between the management host system anddifferent peripheral devices. By default, a management host system is connected usingEthernet. A management host connection using RS-485 or RS-232 is also possible.Corresponding to the available interfaces, one AMC2 can be connected to each COM portusing RS-232 mode. In RS-485 mode, up to eight access controllers can be combined on oneparty line.The AMC2-4R4 is deployed as an independent controller between the management hostsystem and various peripheral devices. By default, a management host system is connected viaEthernet. A management host connection using RS-485 or RS-232 is also possible.The AMC2-4WE is connected between the access controller AMC2-4W and the variousperipheral devices.The extension module AMC2-16IOE is connected to the Access controller AMC2. By default itis connected via RS-485.

Depending on the kind of interface are available the following constellations are possible:– Using RS-232 host connection one AMC2-4R4 can be connected per COM port.– Using RS-485 host connection, up to eight of these modules can be combined on one

COM port.– Up to three extension boards can be connected to and controlled by the AMC2-4R4.

These can be any combination of types AMC2-8IOE, AMC2-16IOE, or AMC2-16IE.

System configurations for Access Control applications.– The minimum configuration consists of:

– one PC with system software,– one AMC2 controller,– one AMC power supply,– one AMC enclosure.

– The maximum configuration depends on the system software,– Each AMC2-4W controller can be extended with an AMC2-4WE extension module.Using an AMC-MUX interface extension on RS-485 host connections it is possible to connectup to eight controllers to a single COM port. Up to 200 AMCs can be connected using theethernet host connection.

Notice!If the host connection is via ethernet then the RS-485 interface can be used for extensionboards.

Using the reader interfaces, up to two RS-485 and two Wiegand peripheral devices can beconnected to each AMC2-4R4. The RS-232 interface can be used for additional input devicessuch as biometric readers or long-range readers. The RS-232 and Wiegand interfaces arepoint-to-point connections, meaning that only one reader can be connected to one interface.The using of AMC2-4WE modules has no influence on the limit of the maximum of controllersin one system, because it is an extension to an AMC2-4W and not a controller.Using Wiegand reader interfaces, up to four peripheral devices can be connected to eachAMC2-4R4. The interfaces are point-to-point connections, meaning that only one reader can beconnected to one interface.



Using RS-485 reader interfaces, up to eight peripheral devices can be connected to eachAMC2. The four reader interfaces are divided into two buses. Interface 1 and 2 are on one bus,and interfaces 3 and 4 are on the other bus. With this arrangement, you can connect allreaders to one interface.The extension interface supports up to three additional I/O boards (AMC2-8IOE, AMC2-16IE,or AMC2-16IOE).

Notice!Risk of damage to equipmentIf excessive force is required to close the front cover then it is probably incorrectly hookedinto the back cover. In such cases the display ’Dialog’ button in the front cover will bemisaligned and will not function correctly.

4.5 Cabling

Notice!Risk of malfunctionThe cables used in the AMC2-4R4 access control system are not prone to electricalinterference. However, you should avoid routing cables close to heavy load switching cablesand equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft)to reduce interference.

Notice!Risk of malfunctionThe cables used in the AMC2-4W access control system are not prone to electricalinterference. However, you should avoid routing cables close to heavy load switching cablesand 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 power to AMC2With the calculation below you can find out which cable type must be used. If you connect thepower supply and the AMC-device with the delivered cable set from the enclosure thecalculation is not necessary.



For distances below 25 m (75 ft) use AWG18 conductors (1mm²). For longer distances, installan additional power supply close to the AMC2 controller.Please, calculate the voltage drop by checking the conductor specifications for characteristicresistance values. The voltage drop shall not exceed 2 V.Example:Length = 100 m/328 ftU = 12V, I = 1A, maximum UDrop = 2V

i.e. RAWG18 (acc. specs) = 6.385 or 20,948

UDrop = 20,948 x 0.1 km x 1A = 2.1V

UDrop = 6.385 x 328 ft x 1A = 2.1VCritical condition! Install the power supply closer to the controller.External power supplies used must be UL certified and must be located in the same room asthe connected AMC2 device. Recommended maximum distance between power supply unitand AMC2 is 3 m (9.84 ft).

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 toConnecting Analog Input Devices, page 82.



4.6 Grounding and ShieldingThe main grounding point at the AMC2-4R4 is connected to pin 2 of the power supplyconnector - see Connecting Diagrams, page 102.It is good practice to shield all wires carrying low level signals.

The main grounding point at the AMC2-4W is connected to pin 2 of the power supplyconnector - see Connecting Diagrams, page 102.It is good practice to shield all wires carrying low level signals.

The AMC2-4R4 allows you to create a central ground or shielding point, simply by settingcertain jumpers. Set these jumpers only if grounding or shielding is not achieved by othermeans.The AMC2-4W allows you to create a central ground or shielding point, simply by settingcertain jumpers. Set these jumpers only if grounding or shielding is not achieved by othermeans.

The AMC2 controller allows you to create a central ground or shielding point, simply by settingcertain jumpers. Set these jumpers only if grounding or shielding is not achieved by othermeans.1. If the AMC2-4R4 has its own power - as in the third example in Overview - Power supply/

consumption, page 49 - the shield will be connected to pin 2 of the power supplyconnector - see Connecting Diagrams, page 102.

2. If the extension module is powered from the AMC2 controller - as in the second examplein Overview - Power supply/consumption, page 49 - the connection should be made as inthe RS-485 for extension modules, page 65 diagram.

3. If more than one extension module is to be connected to an AMC2 controller, and all ofthem to receive power from it as well, then use the RS-485 extension interface for theconnection.

Notice!In the second and third case the jumper on the bottom side of the AMC2-controller must tobe set - see the installation manual of the AMC2-4W.

Notice!Risk of malfunctionEnsure that no ground loops are formed.

Notice!In general the following apply:If the devices have their own power supplies, the shielding is applied to one side only. Thefree 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.

4.14 RS-485 Interface for Card ReadersThe AMC2-4R4 has four RS-485 interfaces. Each interface is connected using a 10-pinpluggable screw connector (S2, S7, S14, and S19).

Figure 4.57: Location of the RS-485 interfaces for external devices



Figure 4.58: Location of the RS-485 interface for external devices

The interfaces 1 and 2 build a bus (bus 1) for its own like the interfaces 3 and 4 (bus 2).All eight possible readers can connect to each of the busses in any combination. However, theaddresses of the readers must be unique on an AMC2.Two readers can connect to the bus.The voltage on the interface is equal to the input voltage of the AMC2-4R4A complete connection diagram of the RS-485 interface is shown in chapter ConnectingDiagrams, page 102.

Notice!Please check which voltage the readers require. If this does not correspond to the inputvoltage, this will require an external power supply.

Notice!If the current consumption on the interface is higher than 1.5A then change the distributionto the other interfaces or use an external power supply for the reader.

Notice!Damage to the device due to wrong voltageMake sure that the readers support the same voltage as the power supply unit that isconnected to the AMC. Readers that do not support the same voltage will be damaged.

Refer to– RS-485 Host Interface, page 55

4.15 RS-232 Interface for Card ReadersThe AMC2-4R4 has RS-232 interface to integrate with RS-232 compatible interfaces. Eachinterface is connected using a pluggable screw connector .
