and fold out on the right-hand side (near the "A") to access it. The installed interface is
intended for emergency power supply only and it is not required as part of normal operation.
The emergency power device supplies locking components with power to enable operation if
the batteries have gone flat. For this purpose, connect the emergency power device
connection cable to the corresponding interface and then switch it on. No other interactions
with the emergency power device are required. A medium with valid authorisation is still
required to operate the locking component.
In this process, please note that this must be a permanent authorisation without a restricted
validity period. Please refer to Emergency media for more information. Immediately replace
batteries after having used the emergency power device to operate locking components and
subsequently update locking components to also enable access with additional media. Please
refer to Replacing batteries and using the emergency power device for more information.
Please note that the AirKey wall reader cannot be supplied with power using
the emergency power device, it is supplied with power using an external
power supply in combination with the AirKey control unit.
