7.2.3.4 IfcAlarmType

7.2.3.4.1 Semantic definition

The distribution control element type IfcAlarmType defines commonly shared information for occurrences of alarms. The set of shared information may include:

  • common properties with shared property sets
  • common representations
  • common materials
  • common composition of elements
  • common ports

It is used to define a alarm type specification indicating the specific product information that is common to all occurrences of that product type. The IfcAlarmType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcAlarmType are represented by instances of IfcAlarm. Refer to the documentation at IfcAlarm for supported property sets, materials, composition, and ports.
