Lock features and parameters: 
 Panel structure: one panel, the use of precision zinc alloy integrated manufacturing process, chip-free processing, to ensure that locks more durable, impact resistant, never loose, no one exposed surface of the lock screw, fully meet the public environments, stronger anti-destructive, longer life. 
 Free hand: The new "stand-alone motor clutch design" technology. When the clutch is closed, the handle only by force; when the clutch out, the hand was idle state, the clutch is fully free from force, truly prevent the door handle by the destruction of the internal structure. 
 Operating voltage: 6V, 4 节 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 normal continuous open 
 Voltage indication: When the working voltage less than 4.8V or so, the red light sensor RF card, this time around could open dozens of times (will be affected by the inconsistency of the battery.) 

 Emergency opening: free from any control, even if the tongue locked, it can open. 
 Opening time: press down the handle to open the door after a valid or not open the door lock automatically 5 seconds; opened the door for 10 seconds if not closed, lock the door will be sent to remind the long song. 
 Reliability: continuous normal induction 1000 there will not be a mistake. 

 Unlock record: lock the "black box" the latest 485 unlock information storage, mechanical key to open a lock record. 
 Guarantee conditions: access to any illegal card (especially all the conductive metal card), the lock will not damage the circuit can still work. 

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

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

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