requirements for routine maintenance, testing and inspection of installed dampers. It also covers installation, testing and commissioning of dampers during initial installation, as well as considerations for the correct design for, and selection of, fi re dampers. Some key areas to study are the requirements relating to system design and damper selection, and the importance of detail and quality of workmanship during installation. As an example, the person designing and selecting the fi re dampers should understand: ■the principles of compartmentation ■the standards and principles for testing FDs and SCDs ■the applications of FDs and SCDs ■ the correct procedures for the selection and installation of FDs
■building services spatial coordination ■ the correct procedures for access to, regular testing, maintenance etc for FDs.
■demonstrate good behavioural and ethical competence. ACR-SEP17-HERONHILL.qxp_Layout 1 09/08/2017 12:28 Page 1
Recognition is given that the required knowledge may not be held by a single party, therefore, the involvement of a manufacturer at the early stage of design, who can support the Dutyholder with respect to the certifi ed applications of the dampers, should be considered. In the case of a new build, once the building has been designed for
compartmentalisation, and the damper is being selected, the type of supporting construction into which the damper is to be installed is crucial. The manufacturer must provide a Declaration of Performance (DoP) and Installation & Operating Manual (IOM) to the Dutyholder, ‘specifi c to the supporting construction’. Without both of these documents, there is no guarantee that the installation will meet the required performance. Failure to install a fi re damper in accordance with manufacturers IOM, without obtaining permission for an installation deviation, will render the fi re damper non- compliant, with responsibility to underwrite the installation falling on those involved in this design decision. After installation, changes to the building use which might impact upon the required damper classifi cation are also critical, as they could void the original installation compliance.
