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.
– If liquid has been spilled or an object has fallen into
the unit.
– If the unit has been exposed to water and/or inclement
weather (rain, snow, etc.).

the operating instructions. Adjust only those controls
specified in the operating instructions. Improper

6en | Safety Instructions AMC2 Modular
Controller
2018-09 | AMC2-4W_UL | Bosch Access Systems GmbH
adjustment of other controls may result in damage,
and require extensive work by a qualified technician to
restore the unit to normal operation.
– If the unit has been dropped or the cabinet damaged.
– If the unit exhibits a distinct change in performance.
7. Replacement parts - If replacement parts are required, the
service technician must use only replacement parts that are
specified by the manufacturer. Unauthorized replacements
may result in fire, electrical shock or other hazards.
8. Safety check - Upon completion of service or repair work
on the unit, ask the service technician to perform safety
checks to ensure that the unit operates properly
9. Power sources - Operate the unit only from the type of
power source indicated on the label. If unsure of the type
of power supply to use, contact your dealer
– For units intended to operate on battery power, refer
to the operating instructions.
– For units intended to operate with external power
supplies, use only the recommended approved power
supplies corresponding to norm EN/UL 60950.
– For units intended to operate with a limited power
source, this power source must comply with EN/UL
60950. Unsuitable replacements may damage the unit
or cause fire or shock.
– For units intended to operate at 12V DC normal input
voltage is 12V DC. Voltage input must never exceed
15V DC.
– For UL installations, the Bosch APS-PSU-60 power
supply may be used, and must be located in the same
room as the connected AMC2 device. Recommended
maximum distance between power supply unit and
AMC2 is 3 m (9.84 ft).
10. Lightning - For added protection during electrical storms
external lightning conductors can be installed. This
prevents power surges from damaging the unit.

AMC2 Modular
Controller Safety Instructions | en 7
Bosch Access Systems GmbH 2018-09 | AMC2-4W_UL |
– For UL installations, lightning protection used must be
UL listed.

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.

3 Introduction
Notice!
To build a UL listed configuration, refer to UL Requirements,
page 45
3.1 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 card provides
adequate storage capability for cardholders and events.

AMC2 Modular
Controller Introduction | en 15
Bosch Access Systems GmbH 2018-09 | AMC2-4W_UL |
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 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, or AMC2-16IOE) can be
connected. The extensions offer 8 or 16 additional inputs and
outputs.

16 en | Introduction AMC2 Modular
Controller
2018-09 | AMC2-4W_UL | Bosch Access Systems GmbH
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.
Notice!
The use of the burglar alarm was not evaluated by UL.
