7.4.3.1 IfcAudioVisualAppliance

Appareil audiovisuel
Audiovisuelles Gerät

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.

Formal Propositions:

CorrectPredefinedType : Either the PredefinedType attribute is unset (e.g. because an IfcAudioVisualApplianceType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
CorrectTypeAssigned : Either there is no audio visual appliance type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcAudioVisualApplianceType.
