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.
