Peer-peer on BACnet via BMS
Alarm differentiation
A single alarm is used for each
fire system object
Different priority alarms can be
generated for different faults or

Efficient for smaller installa-
tions
Aligned to larger installations
Site topology
Costs can be high if the panels
are distributed
Practical for re-use of network
components
Mix of other BT disciplines
Each discipline needs a sepa-
rate integration
MK8000 server may already be
available
Know-how of the integrating
partner
Uses the standard DESIGO
Toolset
OPC integration requires high
