1.2 Safety precautions
Read the 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 on the controller.
!
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.
!
Warning!
Risk of explosion of Lithium battery
The battery can explode if it is replaced incorrectly.
Replace only with the same type as recommended by the manufacturer.
Dispose used batteries according to the battery manufacturer’s instructions.
Notice!
Risk of damage to equipment
Protect the hardware from electrostatic discharge by observing ESD instructions before
unpacking of touching connectors of electronics.
Always switch off power of the AMC2 device before modifying the installation.
Do not connect or disconnect plug connectors, data cables, or screw connectors while power
is on.

3 Introduction
3.1 Description
The extension module AMC2-4WE is equipped with four Wiegand type reader-interfaces plus
eight inputs and eight outputs. Hence with the AMC2-4WE it is possible to double the number
of readers on an AMC2-4W from 4 to 8.
Figure3.1: The extension module AMC2-4WE
The AMC2-4WE can not be deployed as an independent controller but only as an extension
module for the AMC2-4W. Control and access decisions and bookings are carried out by the
AMC2-4W alone.
Notice!
The AMC2-4WE can only be used with AMC2-4W. As it provides Wiegand interfaces it cannot
be coupled with an AMC2-4R4.
The AMC2-4W can be extended by a maximum of one AMC2-4WE plus a maximum of three I/O
extension 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 on
special pages of the AMC2 display.
As the extension modules contain neither memory nor display they are controlled and
monitored entirely by the AMC2-4W.
The AMC2-4W can have an additional interface extension module AMC2-4WE, so that the
number 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 to
another AMC2 is not possible.
The signal settings and parametrization of the readers connected to the extension module, are
carried out by the configuration applications in the access control system and by the
AMC2-4W to which it belongs.
