System limits

3.3.1 Nurse call system
The maximum size of a Flamenco
number of installable IP-SystemManager control units. For each nurse call system,
a maximum of 63 IP-SystemManagers can be installed, consisting of:
 1 IP-SystemManager (operating mode "Local") per ward.
 1 IP-SystemManager (operating mode "System" or "System + Local". An addi-
tional ward can be connected to "System + Local".).
 1 IP-SystemManager (operating mode "Voice Gateway") per Management-
Center.
 1 IP-SystemManager (operating mode "BMA/MED") per connected medical elec-
trical system.
 1 IP-SystemManager (operating mode "BMA/MED") per connected fire alarm
system.
NOTE! If the Flamenco
call system, i.e., with an OSY-ControlCenter, deviating conditions apply. Ask your
contact person at Tunstall GmbH.
The spatial expansion of the nurse call system is limited by the expansion of the IP
network that connects the IP-SystemManager control units to each other.
A maximum of 8 nurse call systems can be connected to one ManagementCenter.
3.3.2 Speech connections
Only one speech connection can be active on each ward at one time.
The number of possible simultaneous cross-ward voice connections results from the
number of wards in the nurse call system divided by 2.
The number of possible simultaneous speech connections at the Management-
Center is physically limited to one since there is only one speech unit.
An announcement can be transmitted to all connected rooms at the same time.
3.3.3 Ward
One OSYnet group bus is connected to one IP-SystemManager for the control of a
ward. A maximum of 110 bus users can be connected to this group bus.
Of the 110 bus users, no more than 55 of them shall be room terminals (superordi-
nate term for all types of room controllers). That means no more than 55 rooms may
be connected to a group bus. The requirement of DIN VDE 0834-1:2016-06 that an
organisational group (= ward) comprises all rooms that can be managed by at least
one person is decisive. The precise number of rooms must therefore be determined
by the owner of the nurse call system.
The following devices are group bus users on the OSYnet group bus:
