4 Functions

To achieve the overall functionality of a fire detection and fire alarm system, basic functions need to be implemented. These functions are identified in Figure 1. They may be complemented by ancillary functions to offer more convenience to the user.

All these functions are performed by components which are inter-linked using wire, radio communication or other suitable means to achieve the overall functionality of the fire detection and fire alarm system.

Functionality may be distributed in one or more component.

Annex A gives additional information about the use of functions and applicable standards.

5 Compliance

Each function performed by a component shall be clearly stated and shall conform to the appropriate parts of EN 54.

Detectors that do not include a decision-making element shall only be considered to conform to the appropriate part of this standard (e.g. EN 54-7 for point smoke detectors) when they are tested and used in conjunction with that component of the system which includes the decision-making element.

Some components to be used in the system may not fall conveniently under the definitions given in Clause 3. In these circumstances the area in which the component is intended for installation shall determine which environmental tests are appropriate. For example, components to be installed in the same conditions as control and indicating equipment shall be subjected to the same environmental tests as control and indicating equipment, but components which may be installed in the same conditions as detectors shall be subjected to the environmental tests specified in the standards for detectors. To determine the correct operation of the component in these tests the overall response of the system, including the component, shall be assessed against the requirements from the appropriate part(s) of EN 54.
