1 High level – contacts of an output relay are open or output transistor is closed;  
2 Low level – contacts of an output relay are closed or output transistor is open. 

10.5. Operation of the turnstile when controlled by an ACS 

When a registered access card is presented to a reader, the reader produces a short 

signal and transmits an access card code to a controller. The ACS authorizes the 
passage and sends a command to the CLB, which opens passage in authorized 
direction. After the passage completion the CLB generates PASS A and PASS B signals, 
locks the passage and resets to home position, after this the turnstile is ready for next 
operation cycle.
