Emergency Override External Battery Power Supply  

When your electronic locker lock battery runs out, our Emergency Override External Battery Power Supply will come to your aid to open the locker. Even though our electronic locker locks have a life cycle of 10,000 - 20,000 uses, in situations where multiple users are assigned access to lockers for short time periods, batteries can run out unexpectedly. A backup power source will come in handy in emergency situations. For use with our Zephyr electronic locker locks ZE-5100-XXX, ZE-5200-XXX, ZE-2654 and ZE-2554.
