Project No.prEN 54-25 rev
TitleThis document specifies requirements, test methods and performance criteria for components used in fire alarms systems, installed in and around buildings (either permanently or temporarily), which use radio frequency links (RF links) to communicate. It also provides product characteristics for the evaluation of conformity of the components to the requirements of this document. This document provides for the assessment and verification of constancy of performance (AVCP) of components using radio links to this document. This document does not cover: — the intended use of radio spectrum, e.g. frequency, power output of devices; — the allowed maximum number of the components using RF links within the FDAS or one transmission path; — the allowed maximum number of the components affected by loss of one transmission path. The effectively and efficient use of the radio spectrum is not covered by this standard and is left to the applicable radio standard.
