1.9 BMS EXPANSION
A. The BMS, as installed, shall incorporate a minimum of 20 percent additional hardware
(field) points without adding controllers or I/O Point Interface Modules (PIM). The number
and type of the installed spare points shall be uniformly distributed between the installed
controllers.
B. Network architecture shall allow unlimited expandability by the addition of new sub
networks and associated routers, gateways, etc.
C. Each BMS as installed shall be expandable, at minimum, to incorporate the following in
addition to the above:
1. A minimum of 200 percent additional hardware (field) points with the addition of
NAC, DCP, Routers, Gateways and ASC.
2. A minimum of 200 percent additional system diagrams in addition to those required
to meet these specifications.
3. A minimum of 10 No. additional interfaces to low voltage building systems of a
similar nature to those integrated under this contract.
D. Subsequent to the potential expansion detailed above:
1. The BMS performance shall not be degraded in any manner and shall meet all
performance criteria detailed in these specifications.
2. Equipment installed under this sub-contract shall not become redundant as a result of
implementing these BMS expansion requirements.
