class Ifc4::IfcAudioVisualAppliance : public Ifc4::IfcFlowTerminal

An audio-visual appliance is a device that displays, captures, transmits, or receives audio or video. Audio-visual appliances may be fixed in place or may be able to be moved from one space to another. They may require an electrical supply that may be supplied either by an electrical circuit or provided from a local battery source. Audio-visual appliances may be connected to data circuits including specialist circuits for audio visual purposes only.

HISTORY New entity in IFC2x4

Type Use Definition IfcAudioVisualAppliance defines the occurrence of any audio visual appliance; common information about audio visual appliance types is handled by IfcAudioVisualApplianceType. The IfcAudioVisualApplianceType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcAudioVisualApplianceType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcAudioVisualApplianceType has ports or aggregated elements, such objects are reflected at the IfcAudioVisualAppliance occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcAudioVisualApplianceType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcAudioVisualApplianceType.HasPropertySets. If both are given, then the properties directly defined at IfcAudioVisualAppliance override the properties defined at IfcAudioVisualApplianceType. Refer to the documentation at the supertype IfcFlowTerminal and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.

Qto_AudioVisualApplianceBaseQuantities

Material Use Definition The material of the IfcAudioVisualAppliance is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcAudioVisualApplianceType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Casing: Material from which the casing is constructed.

Composition Use Definition The IfcAudioVisualAppliance may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcAudioVisualAppliance and RelatedObjects contains one or more components. Aggregation use is defined for the following predefined types:

May contain IfcAudioVisualAppliance components.

Port Use Definition The distribution ports relating to the IfcAudioVisualAppliance are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the audio visual appliance occurrence is defined by IfcAudioVisualApplianceType, then the port occurrences must reflect those defined at the IfcAudioVisualApplianceType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcAudioVisualAppliance PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
