EVVA AirKey & Xesar Emergency Power Device

The EVVA AirKey & Xesar Emergency Power Device (manufacturer reference E.ZU.NG.V1) is an essential backup accessory designed for EVVA electronic access control systems. It provides a reliable solution for when the internal batteries of an AirKey cylinder or Xesar escutcheon have completely failed or run too low on power to operate the lock.

This compact, lightweight device is incredibly easy to use. Simply access the emergency power interface located on the front of the locking component (discreetly positioned beneath the EVVA logo), connect the device's cable, and switch it on. The unit temporarily supplies the necessary power to the locking component, allowing it to function.

Please note that this device does not bypass security; a valid access medium with active authorisation (such as an AirKey fob, card, or a Xesar MasterKey credential) is still required to unlock the door. Once entry is gained, the flat batteries within the lock should be replaced immediately to restore normal operation.
