Building hardware. Electrically controlled hold-open systems for fire/smoke door assemblies. Requirements, test methods, application and maintenance Ingestion-build-48024 in which additional requirement constraints1 Scope This European Standard specifies requirements, methods of test and performance criteria against which the compatibility of components and their performance can be assessed when used in combination to form an electrically controlled hold open system. It also specifies requirements for the integrity of such hold open systems when connected to fire detection and fire alarm systems or other systems, including the signal exchange and technical data
