scope:

This part of EN 54 defines the terms and definitions that are used throughout EN 54. It gives the principles on which each part of the standard has been based and describes the functions carried out by the components of a fire detection and fire alarm system. This European Standard applies to fire detection and fire alarm systems in and around buildings. This European Standard gives the necessary information for the intended use of the series of EN 54 standards. The EN 54 series applies to fire detection and fire alarm systems in and around buildings composed of several components that communicate for the purpose of detecting fire at the earliest practicable moment, and to provide: - local and/or remote fire alarms to organizations having authority to take care of buildings and their environment; - signals to initiate, in the event of a fire, the operation of other fire protection and equipment/systems. The EN 54 series may be used for other applications e.g. mines and ships, but one should consider the specific nature of each application before use. Additional performance and environmental tests may be necessary. This does not preclude the manufacture or use of systems having special characteristics suitable for the protection of specific risks against specific hazards.
