Omfang: <p>This part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std> specifies requirements, test methods and performance criteria for components used in fire detection and alarm systems, installed in and around buildings, which use radio-frequency (r.f.) transmission paths. It specifies requirements for the assessment of conformance of the components to the requirements of this part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std>.</p><p>Where components work together and this requires knowledge of the system design, this part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std> also specifies requirements for the system.</p><p>When the fire detection and alarm system uses wired and r.f. transmission paths, the relevant parts of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std> apply together with this part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std>. Requirements relevant to wire transmission paths are superseded or modified by those included in this part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std>.</p><p>This part of <std std-id="iso:std:iso:7240:en" type="undated"><std-ref>ISO 7240</std-ref></std> does not restrict</p><list list-type="bullet"><list-item><label>—</label><p>the intended use of radio spectrum, e.g. frequency, power output of devices;</p></list-item><list-item><label>—</label><p>the allowed maximum number of the components using r.f. transmission paths within the fire detection and alarm system or one wire transmission path and/or r.f. transmission path;</p></list-item><list-item><label>—</label><p>the allowed maximum number of the components affected by loss of one wire transmission path and/or r.f. transmission path.</p></list-item></list>
