Description
The AMC2 (Access Modular Controller) is used as an access controller in the access control systems:
-
- BISACE (Access Engine) from version 2.0 onward
- AMS (Access Management System)
- APE (Access Professional Edition).
The device controls a group of one to eight access points. These access points, also known as entrances, can be:
• doors
• gates
• barriers
• turn stiles
• revolving doors
• mantraps
• ID card, PIN and biometric readers
• door opening elements
• sensors.
The AMC2 can control a maximum of eight ID readers (depending on the reader type) and fully processes the access logic at the assigned entrances.
The analog inputs have a status recognition of the connected lines.
The relay outputs activate the door opening elements and/or generate the security activation and signaling.
The AMC2 stores all necessary information in a battery-buffered memory and a compact flash storage element. Thus, even when the unit is offline, it checks
independent authorization on access points, takes access decisions, controls closing/opening elements and registers movement events
System overview
1- Host computer 2- AMC2
3-Card reader 4-Communication and power supply
The controller can be connected to the host system through one of the following interfaces, depending on the type of installation:
With RS485 operation, a maximum of eight access controllers can be connected to one party line.
The communication between the host system and the controller via RS485 is encrypted with up to AES256, depending on the firmware version used.
In the communication chain of a system, the access controller is integrated between the host system and the peripheral devices.

Regulatory information
Installation/configuration notes
Power supply
An external power supply (10 to 30 V DC) for the AMC2 is connected to the pin 1 (positive) and 3 (negative). When using an uninterruptible power supply (UPS), the relevant UPS output relay can be connected to the pins:
-
- 4 and 7 for AC.
- 5 and 7 for battery.
- 6 and 7 for DC.
Otherwise, these pins will short-circuit.
Quantity restrictions
-
- Follow the Access Engine installation and configuration instructions regarding the maximum number of access controllers on one access control system.
- The maximum number of cards that a controller can store is 400,000, depending on the access host system and the license used. For further information, refer to the datasheets of the BIS/ACE and AMS access control systems.
Connections to the ID card readers Wiegand interfaces
The AMC2 2WCF has two connections for connecting a maximum of two ID card readers.
The AMC2 4WCF has four connections for connecting a maximum of four ID card readers.
The element interfaces of the ID card reader and the door control are divided into groups, each with reader interface, two input and two output contacts.
The following definitions apply to the Wiegand interfaces:
-
- 10-wire interface (including shield).
- Maximum cable length of 158 m (500 ft) to the ID card reader.
RS485 interfaces
The AMC2 4R4CF has four connections for connecting a maximum of eight ID card readers, using secure OSDPv2 protocol. The interfaces are divided into two buses. A maximum of eight readers can be connected to one interface.
RS485 interface definition:
-
- 2-wire interface: Using the 10-pin pluggable connector.
- Maximum length of the bus: 1200 m.
- Transfer rates: 9.6 kbit/s.
Reader and door models
The AMC2 controls the connected reader through predefined door models.
Door models control in accordance with the relevant security requirements:
-
- Number and usage of the readers connected to the AMC2, such as input and output readers, input readers, buttons.
- Number and application type of the AMC inputs, such as door status, output button, revolving door position.
- Number and usage of AMC outputs, such as door opener, mantrap contact, signal light switching.
The maximum number of entrances to be managed by one AMC2 is ultimately defined by the door models used and their requirements regarding readers and inputs/outputs.
Voltage equalization: grounding
-
- Potential differences can be compensated through the protective grounding with a jumper.
- A line (shield, equipotential bonding line) with protective ground can only be connected in one position.
- For further instructions, see the operating manual.
Contacts
Inputs
The eight analog inputs can be used as digital or analog contacts. For analog use, resistance values can be specified that make it possible to carry out a further check for cable breaks and short-circuits.
Relay outputs
The relay outputs offer the following functions:
-
- The outputs can operate with potential free contacts for external power supply (dry mode).
- The outputs can operate using the internal voltage of power supply (wet mode).
- Only ohm resistive loads can be connected to the relay.
- Inductive loads must be bypassed through recovery diodes. These diodes (1N4004) are enclosed.
General instructions
-
- AMC2 and related equipment should be mounted in a “secured area”.
- Detailed connection conditions are specified in the operating manual.
- After purchase, primary AC power must be done by a licensed electrician.
