External power supply for the wAppLoxx locking systemFor the best possible operation, installation and integration capability, wAppLoxx double knob cylinders are fitted with a long life lithium battery. The status of the battery can be checked at any time via web or app for control purposes. An electronic locking system must, of course, also be prepared for the occurrence of a discharged cylinder battery. The WLX-ESE for wAppLoxx eliminates this problem. If there is a discharged cylinder battery, the external power supply is applied to the cylinder and opening is then possible.
