ACS-2 plus System
Access control system
The ACS-2 plus is an access control central control unit
for up to two doors.Conventional wiring can be used to
connect two separate doors or a single door with an
entry and exit reader.
All the firmware can be upgraded.No time-consuming
replacement of EPROMs is necessary for upgrading the
functions.New program routines or extensions can be
loaded on the control units using “MultiAccess Lite”or
“IQ MultiAccess”access control software.Firmware
updates will be made available for download free of
charge via the Internet.
In online mode, up to 16 ACS-2 units can be operated via
an interface converter and up to 32 via a bus controller.
Access control rights are set up and managed using
“MultiAccess Lite”V1 or later or “IQ MultiAccess”version
V1.xx or later.
The central control unit supports the corresponding opti-
ons of the relevant access control software in each case.
the ACS-2 plus holds all decision rights for door release
and control (even in offline mode).
By using multiple bus controllers or an Ethernet network
up to 999 doors can be managed per location with IQ
MultiAccess.The maximum number ofdoorsthat can be
managed with MultiAccess Lite is 32.
Addition of an Ethernet card (026840.29) allows the
controllers to be integrated directly in existing Ethernet
LANs.
The standard package for ACS-2 plus systems does not
include an interface.The appropriate interface card
should be selected according to the intended use.
