This standard specifies the requirements for service providers and the competence, knowledge, and skills required of employees entrusted with the planning, design, installation, commissioning, verification, handover or maintenance of fire safety systems. This applies regardless of whether the services are provided at the installation site or remotely. Fire safety systems within the meaning of this document are, for example, systems: - for smoke extraction (for example, EAT); - for natural and mechanical smoke and heat extraction (for example, NRA, MRA, RWA); for smoke control (differential pressure systems, such as RDA); smoke barriers (RS).
