Ignoring these tips can result in system malfunctions or damage to prop-erty.Means TIP! Here the text contains tips for easier operation.Means that the country-specific and/or the site-specific requirements of the DEVICE and/orSYSTEM APPROVALS of the fire detection system must be observed.1.4 Abbreviations, special termsIn order to improve the readability of this User Manual, the generic terms „Purging unit“ and„F-BO-AFE70“ are used, and the exact type F-BO-AFE70-2 or F-BO-AFE70-3 is specified only ifit is necessary.The terms „control board“ and AFS70-1 refer to the built-in electronic control of the Purging unit.The term „overpressure“ refers to the difference between the static absolute pressure of the com-pressed air and the static absolute pressure of the ambient air. In colloquial language, this is usuallyreferred to as „pressure“.„ANR“ means that the specification applies to standard reference atmosphere (at a pressure of0.1MPa (1bar), a temperature of 20°C and a relative air humidity of 65%).In this User Manual, the term „aspirating smoke detector“ (which is also abbreviated as „ASD“)refers both to the actual evaluation unit of an ASDas well as sometimes also to the combination of the essential components of which an ASD consists, namely, the evaluationunit, the ASD, the sampling pipe system and sometimes the compressed-air supply, etc.In the context it is always clear what is meant in the particular case.The fire detection control panel is also abbreviated as „FDCP“.„PLC“ is the abbreviation for programmable logic controller.Further abbreviations that are not familiar in everyday usage are avoided in this User Manual.1.5 Important tipsFire detection systems and their components must always be planned, installed and put into opera-tion by specialists who are trained on a continuous basis. The specific specialist training on thefunctions of the aspirating smoke detectors must be provided by the respective manufacturer or bypersons expressly authorized by the manufacturer for this purpose. Since the Purging unit will beintegrated directly into the pipe system of the ASD, the guidelines of the manufacturer of the ASD,with regard to the construction and length of the pipe system, must be observed.The devices that are used in addition to the ASD, such as the fire detection control panel, the powersupply, etc., are only mentioned as examples in this User Manual. The present manual does notprovide any information concerning the expert planning or design of a fire detection system. Itreplaces neither the installer's required technical qualification nor his or her specific training.I56-4252-010D200-104-008
