Grand Rapids, Mich.'s Gerald Ford International Airport recently updated its chillers, boiler plants, air handling units, lighting and zone controllers to be monitored and controlled by a LonWorks-based BAS. The system features both remote and on-site monitoring capability, providing energy management and lower utility costs. It is designed to automatically show the source of fault when an alarm is triggered in the facility. A link is then opened to a file of recommended measures a facility manager should take to rectify the fault. The alarm overview shows the triggered, reset and acknowledged alarms, sorting them according to specified requirements in terms of time, priority, alarm text, category and user. A time delay is normally set to avoid faults.
