How Web-based Solution is able to meet all stated challenges
(A) Identification of Faults
Monitor by LocationTree Hierarchy offers Precise Identification of Faults
Data is centralized yetAccess is Distributed and UniversalData is useful only when readily accessible
Monitor by SystemData Overload is not productive

How Web-based Solution is able to meet all stated challenges
Remote Access ControlEnhanced Security / Replace existing manual control
(B) Substation Security
DeterrenceLocal Alarm

How Web-based Solution is able to meet all stated challenges
High availability of Fire Protection systemA large Majority of Fire Protection Systems are not in proper working condition
(C) Fire Safety
Accountability of ContractorsDowntime recorded - Leaves an Audit Trail
Transparency in Fire Safety ManagementLocal Orders can be matched against actual equipment records

How Web-based Solution is able to meet all stated challenges
(D) Very Large Numbers
Designed to manage a SMALL number of points in a LARGE number of locations
Designed to receive and process concurrent events
Highly Scalable Horizontally and Vertically
