Redundancy
A dual bus system and a dual electronic and mechanical locking system in the locks
guarantee high system stability. The two identical system parts are completely
independent from each other and can therefore function individually.
Voltage monitoring
When the power supply is applied or when the system recovers from energy saving
mode, the state of the battery (system voltage) is checked. When the system falls
below a set warning threshold, an entry is made in the log and a message is
displayed. Press F2 to display the system voltage from the system menu.
Every time the system is restarted (battery replacement) or when the system is
activated, the battery voltage is measured and checked. If the battery voltage falls
below the set warning limit, the message
'!!! Low - Batt !!!' is displayed and also stored in the event memory.
