This system is to be installed indoors within the protected or
restricted area.
The UL evaluated configuration requires the following
restrictions:
– A connected Host Management System to configure the
AMC2-4W access control system, manage card user
database, etc. After configuration is done, the AMC2-4W is
still able to work as intended without any connection to the
Host Management System. However, alarm status of the
system will not be reflected.
– UL evaluated that the protection is set by the Access
System Software as supplementary monitoring equipment.
– The enclosure AMC2-UL01 or AMC2-UL02 is necessary. The
AMC2 devices must be installed in one of these enclosures.
– The tamper contact of the AMC2-4W must be connected to
the tamper switch of the enclosure.

extension interface - the AC fail, DC fail, and BAT fail
contacts must be shorted.

– For host system connection, only the Ethernet (RJ45) port
must be used. The RS-232 and RS-485 host connections
may not be used in UL installations. The RS-485 slave
connection may be used for connection to other AMC2
devices only. It may not be used for connection to readers
or other accessories.
– All units are to be powered by the Bosch APS-PSU-60
power supply for UL installations. The power supply must
be located in the same room as the connected AMC2
