Unit of Measure in Alarms
When creating an alarm, the alarm limit and deadband values inherit the unit of the monitored variable. You can change the unit of the alarm to any unit within the same unit category as the monitored variable.
Note:
You cannot define a unit to an alarm that monitors a unitless variable.
If the unit of a monitored variable is replaced by a unit within the same unit category as the unit of the alarm, Building Operation automatically handles the conversion. If the unit of the monitored variable is replaced by a unit that belongs to another unit category, the alarm is disabled by Building Operation. Building Operation triggers a system alarm to notify that the alarm is disabled due to an impossible unit conversion.
