TwinLock 7220
Version 1.08A 23
Power Failure
The FlatControl receives its power supply via each of the two bus cables. When a
voltage failure occurs, an emergency current feed for the entire system is possible via
a jack at the bottom of the keyboard.
For this, an adapter cable 7237-101-0 and a 9 volt block battery (alkaline type) is
required. For the connection of the adapter cable, see figure.
Real time clock
The date and the time are generated by a specially buffered real time clock and will
survive even if the system receives no current for several days.
If a real time clock still happens to be deleted, the system will be in an undefined
state.
More functions
Protection against locking the locks while the bolt system is open.
Constant self-diagnosis of the bus lines and system components.
Log entry of all warning and error messages.
Validity check of entered times and dates.
