Description |
---|---|---|---|
Accepted Modes |
Q |
Uses BAC LifSfty Mode (BACnet Lifesafety Mode) (Set 189). |
Specifies all the values the Life Safety Mode attribute accepts when written. |
Event State |
B |
Uses BAC Event State (Set 5). |
Indicates if an active event state is associated with the object. If the object supports intrinsic reporting, this attribute indicates the event state of the object. If not, the attribute is Normal. |
Life Safety Mode |
W,Q |
Uses BAC LifSfty Mode (BACnet Lifesafety Mode) (Set 189). |
Specifies the operating mode of the Life Safety Point object. The Life Safety Point object generates Change-of-Life-Safety event notifications for any mode transition if the flags in the Event Enable attribute are set. |
Maintenance Required |
O |
Uses BAC LifSfty Maint (BACnet Lifesafety Maintained) (Set 187). |
Indicates that maintenance is required for the life safety point. This may indicate periodic maintenance or parameter-determined maintenance, such as a dirtiness value for an associated detector. |
Operation Expected |
Q |
Uses BAC LifSfty Oper (Set 190). |
Specifies the next operation expected by this object to handle a specific life safety situation. |
Out of Service |
B,C,W |
Indicates (when True) that the Present Value and Reliability attributes are decoupled from the physical input to the object and their values may be changed for simulation or testing purposes. Functions that depend on the values of the Present Value or Reliability attributes continue to respond to changes while Out of Service is True, as if those changes had come from the physical input. Additionally, the Out of Service state of the Status Flags attribute is set to True and the Fault state is decoupled from the physical input when Out of Service is True. |
|
Present Value |
W,D,R,Q |
Uses BAC LifSfty State (BACnet Lifesafety State) (Set 186). |
Indicates the current value of the Life Safety Zone object. When Out of Service is True, this attribute is writable. |
Reliability |
B,W |
Uses Reliability (Set 503) |
Indicates whether the Present Value is unreliable. |
Silenced |
Uses BAC LifSfty SilState (BACnet Life Safety Silent State) (Set 188). |
Indicates whether the most recently occurring transition for this object produced an audible or visual indication that has been silenced by the recipient of a Life Safety Operation service request or a local process. |
|
Tracking Values |
O |
Uses BAC LifSfty State (BACnet Lifesafety State) (Set 186). |
Reflects the non-latched state of the Life Safety Zone object. This attribute continuously tracks changes in the latched state of the object. |
