Control module and restricting access.
Main functions: 1. Restricting access to the room using the identifiers of RFID or other. 2. Storing user base of about 20,000 entries. 3. Time schedules and levels of access - 20 species. 4. Cyclic base events - 8000 latest. 5. Inputs control sensors, a good power supply, fire alarm, tamper and other programmable discretion - only 9, each input is able to control the current in the loop. 6. Outputs to actuators - 4, (NC, NO). 7. Galvanically isolated RS-485 interface for control from the host computer. 8. Response time on the interface to run commands related to database events and identifiers - <10ms. The system is ARM LPC2214.
