INSTALLATION
ASSEMBLY
Make sure the location for installation has no strong low frequency electro-magnetic wave. Especially
in the range of 100-200Khz
If there is more than one keypads with the same operation frequency installed closely in the
location, make sure that they are at least 60cm (2ft) apart from each other to prevention
interference.
Do not apply power to the system while it is in installation.
Check carefully all the wirings are correct before applying power to the system for testing.
1) Prevent Interference:
The EM Card reader is working at the frequency of 125Khz. Installation precautions are necessary.
2) Prevent Accidental Short Circuit:
In the previous experience, most of the damages caused in the installation are accidental touching
of the components on circuit board with the wires carrying power. Please be patient to study the
manual to become familiar with the specifications of the system before starting the installations.
PRECAUTIONS
4) Split-decoded Multi-station Access Control Door Lock
Description
This is an expansion of application (3). The DK-2852 is expandable to a multi-station system in
Split-decoded operation. It is compatible with the auxiliary readers AR-2802 and the auxiliary
reader-keypads AR-2806, AR-2807 & AR-2809. Total 3 auxiliary readers or reader-keypads can
be connected in parallel with the Data I/O Bus. They provide the same functions like the master
keypad in using cards and user codes. The DK-2852 that is the server of the system manages
the data with its Data I/O Bus among the associated devices. This approach gives high security
in sabotage prevention and user convenience.
