contained in the folder titled "_UL" on the delivered CD.
Important Safety Notes
1. Read, follow, and retain instructions - All safety and
operating instructions must be read and followed properly
before putting the unit into operation. Retain instructions
for future reference.
2. Do not ignore warnings - Adhere to all warnings on the unit
and in the operating instructions.
3. Accessories - Use only accessories recommended by the
manufacturer or those sold with the product. Accessories
not recommended by the manufacturer must not be used,
as they may cause hazards.
4. Installation precautions - Do not place this unit on an
unstable stand, tripod, bracket, or mount. The unit may fall,
causing serious injury to persons and damage to the unit.
Mount the unit according to the manufacturer’s
instructions.
5. Service - Do not attempt to service this unit by yourself.
Opening or removing covers may expose you to dangerous
voltages or other hazards. Refer all servicing to qualified
service personnel.
6. Damage which requires service - Disconnect the unit from
the main AC or DC power source and refer servicing to
qualified service personnel under the following conditions:
– If the power supply cord or plug is damaged.

Safety Precautions
Read instructions!
Before working with the AMC2 device, read these instructions
carefully. Make sure you have understood all information
described in this document.
Warning!
Risk of electric shock
External power supplies must be installed and put into service
by qualified personnel.
Ensure compliance with the relevant regulations.
Ground the controller.
Disconnect both AC and battery power supply before working

Warning!
Risk of fire
Installation of the AMC2 device must comply with any local fire,
health, and safety regulations. A secured door that may be part
of an escape route from an area must be installed with:
Install a fail-safe lock (A), so that the door will be released if
power fails. Ideally, use a magnetic lock.
Install a normally-closed break glass or a manual pull (B) in the
lock supply wiring, so that in an emergency the fail-safe lock
can be immediately powered down.

Introduction
Description
The APC-AMC2-4WCF (also called AMC2-4W, AMC2, or
controller) is equipped with four independent interfaces for
Wiegand type readers. 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.
Figure 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 electronics are completely covered by a plastic
housing. The liquid crystal 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 in each
room. This leads to an excellent reliability and a very high
redundancy without extra cost.
Figure 3.2: The AMC2-4W in a four door safety lock
The AMC2-4W 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 AMC2-4W 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 the burglar
alarm system if an intrusion or system alert is detected. If the
eight inputs and eight outputs 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 16 additional inputs and outputs.
The setup procedure for an AMC2-4W is made very simple and
fast by the use of door templates. Once selected, all the inputs
and outputs are predefined. These settings can be changed to
choose every free contact of the controller or a connected
extension.

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 using Ethernet.
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 port using RS-232 mode. In
RS-485 mode, up to eight access controllers can be combined
on one party line.

Using Wiegand reader interfaces, up to four peripheral devices
can be connected to each AMC2-4W. The interfaces are point-topoint connections, meaning that only one reader can be
connected to one interface.
The extension interface supports up to three additional I/O
boards (AMC2-8IOE, AMC2-16IE, or AMC2-16IOE)and one
AMC2-4WE. All extension boards are controlled by the AMC2
and are freely combinable.
