3.1.1 Battery management
The electronic door handle CX2172 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 two 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
door handle is accompanied with flashing of red light (5 times) and 5 short
audible signals.
The battery should be replaced immediately.
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 access data, the event log, the settings of the door handle 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.
