Lock features and parameters: 
 Panel structure: one panel, the use of precision zinc alloy integrated manufacturing process, free chips processing, to ensure that locks and more durable, impact-resistant, never loose, no one locks the exposed surface of the screw, fully meet the public environments, anti-destructive stronger, longer life. 
 Free hand: The new "stand-alone motor clutch design" technology. When the clutch is closed, handle only by force; when the clutch out, the hand was idle state, the clutch completely without power, truly affected to prevent the destruction of the handle locks the internal structure. 
 Operating voltage: 6V, 4 high energy alkaline batteries (recommended Nanfu or Duracell batteries) 
 Static power consumption: <12 microamps 
 Dynamic power consumption: 110 mA ~ 150 mA 
 Battery life: more than 15,000 times the normal continuous open 
 Voltage indication: When voltage lower than 4.8V or so, after the red light induction RF card, then can open the door dozens of times or so (will be affected by the inconsistency of the battery). 

 Emergency opening: free from any control, even if the party locked tongue, but also open. 
 Opening time: Press the handle to open the door after a valid or not open the door lock is 5 seconds; open the door after 10 seconds if not close, long locks will be issued within a song to remind closed. 
 Reliability: 1000 consecutive normal sense there will not be a mistake. 

 Lock record: lock in "black box" stores the latest 485 unlocking information, mechanical key opening a lock record. 
 Guarantee conditions: access to any illegal cards (especially all the conductive metal card), the circuit will not damage the lock, still work. 

 Mechanical key: a drive system is completely independent of the mechanical emergency unlocking, high security mechanical key to ensure the normal emergency door still open 

 Installation requirements: in the 38 ~ 55mm thick door between, if the door surface is decorated, the lace should be away from the door edge in the 110 ~ 105mm or more. 

 Card Type: American TEMIC's induction card (non-contact card), or the Netherlands PHILIPS company Mifare1 induction card (non-contact card).
