BACnet
The object types that Flex-Net uses are binary input, analog input, multi-state input, life safety
point and binary output. The following table identifies which fire devices are classified under
which BACnet object types.
Each of these object types have an associated set of properties. These properties identify the
object and the state it is in. The table below lists the properties associated with each BACnet
object that are used by the Flex-Net system. Some of the properties below are static, while
others are dynamic and are used to determine the state the object is in. The dynamic
properties in the table are bolded.
Each dynamic object property uses different types of information to describe the state of the
property. The type of information reported can also vary between different object types for the
same object property. The following discussion describes the different values each dynamic
object property can have for the different object types.
BINARY INPUTS:
The
Present Value
property can be in one of two states: active or inactive.
For the
Status Flags
property a Boolean array [_,_,_,_] is displayed with each value in the
array representing the presence (1) or absence (0) of an Alarm, Fault, Override or Out of
Service respectively. For example a signal of 1,1,0,0 indicates the presence of an alarm and a
fault. Note that for Flex-Net override is never used. For the
Event State
property one of three
states is possible: normal, fault or off normal.
ANALOG INPUTS:
The
Present Value
property is represented by a raw analog value in the
form of a pulse width PW4 signal. For the
Status Flags
property a Boolean array [_,_,_,_] is
displayed with each value in the array representing the presence (1) or absence (0) of an
