When a Binary Output Object (BO) (supply fan command) is commanded On, the Normal State for the associated Binary Input Object (BI) (supply fan status) alarm extension is also On. After the Reference Delay Time, the current state of the BI is compared to the Normal State. If the BI is still Off, an alarm is detected. The Reference Delay Time is also used when the BO is commanded Off.

Specifies the feedback delay in seconds. The purpose of the Reference Delay Time is to allow time for equipment to start or stop before the status is compared to the command.
