9.5.1
Prewarning threshold
If the battery capacity drops below the prewarning threshold, an audible warning signal is
emitted when a KEK medium is presented (as a factory default) and the green/red LEDs flash
alternately. The prewarning threshold has no influence on access privileges.
You should replace the batteries at your earliest convenience
9.5.2
Warning threshold
If the battery capacity drops below the warning threshold, an audible warning signal is emitted
when a KEK medium is presented (as a factory default) and the green/red LEDs quickly flash
alternately. Additionally, the red LED flashes every five seconds after this. The warning threshold
has no influence on access privileges.
If the battery capacity drops to just above the works’ minimum power definition, both LEDs
flash every 5 seconds.
You must replace the batteries as soon as possible!
9.5.3
End of battery life
If you ignore the warning thresholds and the battery capacity drops to a level where operations
are no longer supported, the electronics automatically switch to the predefined status. This
status <<Status at end of battery life>> can be set/modified at any time using the KESO
Management Software.
IMPORTANT:
At end of battery life neither an a visible nor an audible signal is issued. If you set the
status to <<open>>, the handle is engaged at end of battery life, thus allowing access
to anyone!
