Foreword
This document (CEN/TR 15276-1:2009) has been prepared by Technical Committee CEN/TC 191 “Fixed
firefighting systems”, the secretariat of which is held by BSI.
This document has the general title Fixed fire-fighting systems – Condensed aerosol extinguishing systems
and will consist of the following parts:
 Part 1: Requirements and test methods for components;
 Part 2: Design, installation and maintenance.

Introduction
It has been assumed in the preparation of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people in the specification, design, installation, testing, approval,
inspection, operation and maintenance of systems and equipment, for whose guidance it has been prepared,
and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant.
Product certification: Users of this document are advised to consider the desirability of independent
certification of product conformity with this document based on testing and continuing surveillance, which may
be coupled with assessment of manufacturer quality systems against EN ISO 9001.
Fire-fighting systems covered in this document are designed to provide a supply of fixed condensed aerosol
extinguishing medium to extinguish fire.
The requirements of this document are made in the light of the best technical data known to the working group
at the time of writing but, since a wide field is covered, it has been impracticable to consider every possible
factor or circumstance that might affect implementation of the requirements.
It is important that the fire protection of a building or plant be considered as a whole. Aerosol extinguishant
systems form only a part, though an important part, of the available facilities, but it should not be assumed that
their adoption necessarily removes the need to consider supplementary measures, such as the provision of
portable fire extinguishers or other mobile appliances for first aid or emergency use, or to deal with special
hazards.
Aerosol extinguishants have been recognized as effective media for the extinction of Class A fires (solid
surface burning fires) and Class B and Class C fires according to EN 2, but it should not be forgotten, in the
planning of comprehensive schemes, that there may be hazards for which these mediums are not suitable, or
that in certain circumstances or situations there may be dangers in their use requiring special precautions.
Advice on these matters can be obtained from the appropriate manufacturer of the aerosol generators or the
extinguishing system. Information may also be sought from the appropriate fire authority, the health and safety
authorities and insurers. In addition, reference should be made as necessary to other national standards and
statutory regulations.
It is essential that fire-fighting equipment be carefully maintained to ensure instant readiness when required.
Routine maintenance is liable to be overlooked or given insufficient attention by the owner of the system. It is,
however, neglected at peril to the lives of occupants of the premises and at the risk of crippling financial loss.
The importance of maintenance cannot be too highly emphasised.
Condensed aerosol may contain traces of toxic substances like those produced by a fire, and will obscure
vision like smoke from fire.
