Multi- Station Access Control Electric Lock
Description
The AR-2808 is expandable to a multi-station system for user convenience with the auxiliary
reader AR-2802. Maximum 3 AR-2802 can be connected in parallel with the Data I/O Bus of
the AR-2808. The auxiliary reader(s) reads the Cards as like the master reader AR-2808
which is the server of the system to manage the data from the auxiliary reader(s).

INTRODUCTION
AR-2808 is a self-contained access control reader designed to drive electric door lock directly. It
accommodates up to 500 proximity EM cards and its output is compatible with the Fail-safe and
Fail-secure electric locks. The door lock striking time is programmable. A built-in door chime relay
contact is also available to operate an external low power door chime. It is a full feature compact
reader ideally for the access control system in small office and home applications. The system
employs solid state switch instead of relay contact for door lock strike. It gives longer service life and
prevents the sabotage of opening the door with strong magnet.
AR-2808 is built-in with Data I/O bus for system expansion. Maximum three optional card readers
(AR-2802) can be connected with it to make a multi-station access control system.

Operation Indicators
The 5 LED indicators with number 1, 2 ,4 and 5 in green and number 3 in amber color show the
status of the system in Operation Mode or in Programming Mode.
1) They indicate the Storage Group of an EM card when it is read in Operation Mode.
2) They show the status of feature settings in Programming Mode. See “Programming” &
“Operation” sections for the details.

Card Reader Window
It is a place for reading EM cards.

Door Bell Button (Function Selector)
This button has two functions. It is a door bell button in normally operation and is a function
selector in programming mode. See the details in “Programming” & “Operation” sections.
Apart from standard-alone operation, AR-2808 is expandable to be a Multi-station System with the
optional auxiliary reader AR-2802. Maximum three optional readers can be allowed and the
connection is very simple. Just connect the devices in parallel with the Data I/O Bus of the
AR-2808. The AR-2808 acts as a server of the system and manages the data among them.
A Multi-station System provides higher security in access control and user convenience to operate
an electric lock at different locations. Such as a dual reader system for area needs controlling of
going in and going out with proximity EM cards.
The optional reader is available in standard version (AR-2802S) and advanced version
(AR-2802A). The advanced version also provides Wiegand and RS-232 data outputs for custom
project development with access control panel and / or PC.
The AR-2802 is also compatible with all the Tri-Tech keypads in the 2nd generation DK-2800
series for system expansion.
*Please contact your local agent for the optional reader if system expansion is required.
