Xesar emergency power device
Figure 21: Emergency power device (sample image)
The emergency power device supplies access components with power to enable operation in the
event that the batteries have been drained. 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 Master Key authorisation is required
to operate the Xesar access component.
Immediately replace batteries after having used the emergency power device to operate access
components and subsequently update access components; using the Xesar tablet to once again
enable access with all authorised identification media.
The installed interface below the EVVA logo in conjunction with the emergency power device is
intended for emergency power supply only and it is not required as part of normal operation.
The emergency power device is optionally available.
Product code: E.ZU.NG.V1
Please note, you need an identification medium with "MasterKey" au-
thorisation to open Xesar access components supplied with emer-
gency power, as the time setting is lost if the power supply is inter-
rupted for too long which causes standard media to be unable to open
them.
