Often, oftenthese integrate fire, security, and lighting controls into one system. These systems typically use one or more central controllers to command and monitor the remote terminal unit controllers, and they communicate with one or more personal computers that are used as the operator interface. These control systems are typically used on large commercial and industrial buildings to allow central control of many [[HVAC]] units around the building(s). The latest systems use the building [[ethernet]] for communications between central controllers, and allow operator access from a [[web browser]].▼
