【Card Cabinet Lock】How to supply power to the Sensor Locker Lock?
Update Time:2019-10-12

The sensor locker lock is powered by 4pcs AA Batteries, last 5-10 months normally.

If low Voltage (<4.8V),  there will be alarm sound to remind you changing battery.

All locks we supply have an external power port on it. 
If battery totally exhausted, connect a battery case with 4 pcs AA battery, then unlock. 
You don't have to destroy the locker/cabinet if battery dead.

You can also use a  transformer to transform your city power (AC) to DC (6V) to supply power to all locks centrally.
