ACCESS CONTROL STANDBY POWER LEVEL II - An access control product for units
employing Model APS-PSU-60 Power Supply for 12 VDC and 24 VDC Mode. Level II
operates for 30 minutes.
A connected Host Management System to configure the AMC2 controller, manage card
user database, etc. After configuration is done, the AMC2 controller 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 Controller and
Extension devices must be installed in one of these enclosures.
The tamper contact of the AMC2 Controller must be connected to the tamper switch of
the enclosure.
In one enclosure: when using an AMC2 controller and an AMC2 extension board, if the
AMC2 Extension board is supplied via the extension interface, the AC fail, DC fail, and
BAT fail contacts must be shorted.
The door locks should be connected as fail safe (NFPA 101).
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 Extension
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 device.
Recommended maximum distance between power supply unit and AMC2 is 3 m (9.84 ft).
Wiring methods shall be in accordance with the National Electrical Code (ANSI/NFPA70 -
Articles 725 and 800), local codes, and the Authority Having Jurisdiction (AHJ).
All interconnecting devices and wiring must be UL listed and or/recognized.
The minimum wire size used for connecting external devices shall be at least 26 AWG,
depending on the electrical power consumption.
Products are not intended to be installed or mounted in air-handling spaces.
To detect the four states of the input, the voltage drop in the connecting cable may not
exceed special values. For UL installations only the RS = 2k2 and RP = 2k2 End-of-Line
resistors may be used.
