3 Introduction

3.1 Description of the AMC2 4W

The AMC2 4W is equipped with four independent interfaces for Wiegand type readers. By that it is able to control two doors with a reader in each direction and up to four doors with a reader in one direction only.
Fig. 3.1 The Access Modular Controller AMC2 4W
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 AMC2 4W electronic is completely covered by a plastic housing. The LC Display provides all important status informa­tion. Using the AMC2 4W gives you the full functionality and the offline capability of a complete access control system on each room. This leads to an excellent reliability and a very high redundancy without paying extra money.

Fig. 3.2 The AMC2 4W in a four door safety lock
The AMC2 4W can communicate upstream to the host com­puter via eight 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 4W 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 an external alarm system if an intrusion or system alert is detected. If the eight input and output on board are not enough to configure the system up to three additional extensions (AMC2 8I-8O-EXT or AMC2 16I-16O-EXT) can be connected. The extensions offer 8 or 16 additional inputs and outputs. The setup procedure for an AMC2 4W is very simple and extremely fast by the use of door templates. Once selected, all the inputs and outputs are predefined. This settings can be changed using the Device Editor of the BIS Configuration Browser in that way to choose every free contact of the AMC2 4W or an connected extension.

3.4 System Overview

The Access Controller AMC2 4W is connected between the management host system and different peripheral devices. By default a management host system is connected via Ethernet. A management host connection via RS-485 or RS-232 is also pos­sible.
Fig. 3.6 System overview
The number of controllers in one system is limited to 200. Corresponding to the available interfaces one AMC can be con­nected to each COM-Port using RS-232 mode. In RS-485 mode up to eight access controllers can be combined on one party line. Via Wiegand interfaces up to four peripheral devices can be connected to each AMC2 4W. The interfaces are point-to-point connections - this means that only one reader can be connected to one interface.

AMC2 4W Installing | en 25

5.4 Cabling

CAUTION!
The cables used in the AMC2 4W access control system 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.
Grounding and Shielding
The main grounding point at the AMC2 4W will be connected with pin 2 of the power supply connector - see Figure 7.6. It is good practice to shield all wires carrying low level signals.
The AMC2 4W enables you to set up a central ground or shield­ing point, simply by setting a couple of jumpers. Set these jumpers only if ground or shield is not connected otherwise.
WARNING!
Risk of damaging equipment!
!
When using multiple AMC2 4W devices, set the ground main jumper only once to assure a central point star connection.

5.4.1 Conductor data for connection to power supply

For short distances below 25m (75 feet) use AWG18 conduc­tors. For higher distances install an additional power supply close to the AMC. Please, calculate the voltage drop by checking the conductor specifications for characteristic resistance values. The voltage drop shall not exceed 2V. Example: Length = 100m/328 ft

NOTE!
Generally the following counts: – If the devices have an own power supply, the shield will be
connected on one point, only. The free end should be protected to avoid connections.
i
If the device will be provided by an other one, the shield
have to connect on both sides.
WARNING!
Take care that there are no grounding loops.
Setting jumper JP1 connects the internal ground of the AMC2 4W to the ground of the RS-485 host interface. Jumper JP2 manages the PAG. Settings jumper JP1: If the ground conductor and the shield on the host are not con­nected and ... – no partyline exists, the jumper JP1 is set (= A2) – a partyline exists, ...
the jumper JP1 is set at the first device, only (= A2) Settings jumper JP2: If the ground conductor and the shield on the host are not con­nected and ... – no partyline exists, the jumper JP2 is set (= A3) – a partyline exists and PAG is connected, ...
the jumper JP2 is set at the first device, only (= A3) – a partyline exists and PAG is not connected, ...
the jumper JP2 is set at all devices (= A3)
NOTE!
If the AMC2 4W is set to RS-232 mode, Jumper JP1 (= A2) must

Fig. 5.19 Wet mode and dry mode of the AMC2 4W relay outputs
WARNING!
Keep in mind the following specifications.
!
For the protection of damage the relay keep in mind, that ... – the maximum switching current is 1,25A – the maximum switching voltage is 30V DC – ohm resistive load can be connected to the relay, only – inductive loads have to be short circuited using recovery
diodes - see: Figure 5.20. These diodes (BAX12A) are sup­plied with every AMC2 4W package.
If you need higher voltage for special constructions you
can connect external relays to the outputs. Recommended, depending on the power supply mode, are the relay types of the company Wieland:
Flare move 12DC1W10A
Flare move 24DC1W16A
But you can also use products of manufacturer in your country - take care that the values of the product are iden­tical with the products listened above.
