BUILDING MANAGEMENT SYSTEM FUNDAMENTALS
The advantages of an in-depth integrated system are:
— First costs and ongoing operating costs are usually lower
— Interdependence between subsystems, such as smoke

— Independent operating centers at remote locations can
be provided

— Third party LonMark™ and BACnet points may be
positioned on or added to standard system graphics.
The disadvantage of this type of integration is that care must
be taken in configuring the system to be sure that transmission
speeds are adequate for all parts of the system.
