The document discusses an integrated building management system (BMS) that provides one stop service for system integration, implementation, consulting, and maintenance. It describes how the system allows centralized monitoring and control of buildings within a complex from a command room through a converged IP network connected to various sensors, detectors, devices and actuators. The integrated network uses open protocols and allows for group monitoring, control, and communication across buildings to provide energy savings, increased efficiency, systematic maintenance, and reduced risks through a single integrated solution.
