New BACnet standard offers significant improvements to alarm handling

Changes to the newly published BACnet standard from ASHRAE will encourage smart building automation controls systems including alarms. ANSI/ASHRAE Standard 135-2012, BACnet – A Data Communication Protocol for Building Automation and Control Networks, allows building equipment and systems manufactured by different companies to work together. “With the changes in alarming, we hope to see alarming support in smaller devices, which should provide more alarm and fault detection with a lower engineering cost,” says an ASHRAE standards committee chairman.
