1. Internal Power Supply Mode
Use the internal power to supply for the electronic lock, so that the lock can be connected
to the door station directly. Note that the door station can only output 12Vdc power, Any high-
power lock should use external power connection or it might cause damage to the door station.
• The rated power of the lock must be less than 12Vdc 300mA when using internal power
supply mode
• The GND must connect to the negative of the lock, and the COM connect to the positive .
• Jumper set to 1-2 position for Power-on-to-Unlock safety type( Normally open mode );
set to 2-3 position for Power-off-to -Unlock type( Normally closed mode ).
• If different unlocking time is needed to be configured, change the Unlock Timing on
door station.
