battery status of the 16 most recently operated locking units is stored on the key.
The battery status information is sent to Keyvi and deleted from the key if the key
is read by an automatic programming terminal or a programming station. A
prerequisite is that the key should have been prepared for writing the information
and the option
Key feedback
should be set in the knob cylinder
.

Battery management
The electronic double knob cylinder CX6182 comes with a battery management
system, which indicates the need for battery replacement by means of a visible
and audio signal when the battery power reduces (capacity loss) during the last
1,000 operations of battery (see chapter
7.2.1 battery replacement).
The signal is given out in three phases:
The battery needs to be replaced soon.
If an authorized key is held in front of the reading unit, then the engaging of the
knob cylinder is accompanied with flashing of red light (5 times) and 5 short
audible signals.
The battery needs to be changed.
If an authorized key is held in front of the reading unit, then the red LEDs flash (5
times) accompanied by 5 short audible signals. The engaging of the door handle
is delayed by 5 seconds, during which time the green LEDs flash.
The battery needs to be changed immediately.
If an authorized key is held in front of the knob module, no locking access right is
issued, but rather the knob module goes to the battery change position. In
addition, the knob module flashes red 5x and gives 5 short acoustic signals.
The access data, the event log, the settings of the knob cylinder and the time are
stored in the non-volatile memory and are thus retained even without power
supply, for example when changing the battery or if the battery is completely
drained. The time is written to the non-volatile memory once every 30 minutes.
When the power supply is disrupted, the clock stops after a few seconds and
continues from the last saved value once the power supply is restored.
