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
