ST-880
4-Door Network Access Controller
Maximum of eight 26/34 Wiegand readers to connect with one ST-880 controller. It is suitable for reader with Wiegand output as open collector. Controller provides power for the readers to control all corresponded electric locks.
It features with computer connection and standalone operation, Maximum 30,000 records of data to save when it is standalone. The capacity of records saved according to its hard disk capacity when it is connected with computer.
ST-880 has 50,000 card registration capability. User is able to set personal password and valid time frame to access for every card.
When it is connected with computer, instant data receiving and enquiry can be made to check its usage. It is able to check a user’s in/out status at specific time from the computer database.
20 sets of time zone. Every time zone as Monday to Sunday. 8 sets of time frame for everyday to set available.
The range of main reader access control:
? Proximity: It must be registered before use.
? Password and proximity: Enter personal password and then proximity.
? Time zone: Setting the effective of year, month, day, week, time frame.
