Nailor Industries Inc. reserves the right to change any information concerning product or specification without notice or obligation.

The Air Monitor BACnet stack supports the optional property

“DESCRIPTION”.

This is used to indicate the type of information in the object.

For example, for an ELECTRA-flo system, the description will

indicate as “Total Flow” for average flow, or “Avg Temp” for

average temperature. If the object belongs to a sensor in the

system, it will be indicated as “SensorN Velocity” or “SensorN

Flow”, where N is the sensor address. The number of AI objects

is determined by the total number of sensors in the system x

2 with an additional 2 AI objects for system average flow and

system average temperature. For example, an ELECTRA-flo

system with 8 sensors will have a total of 18 AI objects.

Usage of Status Flags

• Each object supports status bits IN_ALARM, FAULT, and

OUT_OF_SERVICE.

• The OOS property indicates the physical input to the object

is not in service.

This will be set by the transmitter if someone intentionally

removes the sensor from the network. If the transmitter

determines there is a problem with any sensor in question,

the OOS bit is set along with the FAULT bit. If the OOS

property is set, data from the physical device will not be

used in any calculation.

• IN_ALARM is set for values which exceed the predetermined

values set in the transmitter memory. This field only affects

the Avg Temp and Avg Flow Analog Input objects

BACnet Engineering Units for Analog Inputs (Defaults)

Flow Rates: Cubic feet per minute, Liters per minute

Temperatures: Degrees Fahrenheit, Degrees Celsius
