Web-enabled BMS workstations and web-enabled NAE controllers
Central security redundant database server
Smart card server and smart cards
Disaster recovery location
Building security system and CCTV
Access control and intercom systems
Fire alarm on the same backbone
Lifts and elevators system integration
Generator, UPS and power metering
E-banking terminals

Main switchgear and distribution panel boards
