Foreword
This document (CEN/TR 15276-2:2009) 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 firefighting 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 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.
Small scale fire tests, comparable with the test methods mentioned in this standard, indicate that aerosol
extinguishants can be recognized as effective media for the extinction of certain 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, the enclosure and the protected occupancy is carefully maintained
and managed to ensure instant readiness when required and effectiveness of the protection. 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. This standard requires, as a precaution, that the room is evacuated and sealed off
whenever a generator is activated - much like recommended response to fires. Precautions include
evacuation of the proximity area, criteria for re-entering and other safeguards as stated in paragraph 5.

1 Scope
This document specifies requirements and describes the methods for the design, installation, testing,
maintenance and safety of condensed aerosol extinguishing systems and the characteristics of the

This document is intended as a standard covering solely condensed aerosol.
This document is not applicable to explosion suppression applications.
This document is not intended to indicate approval of the extinguishants listed herein by the appropriate
authorities, as other extinguishants may be equally acceptable.
This document is applicable to the extinguishants which fulfil CEN/TR 15276-1.

automatic or manual activation leading to the physical discharge of extinguishant
3.2

acceptable to a relevant authority
3.3
authority

determining acceptability
NOTE The authority may base acceptance on conformity to the appropriate standards.
3.4
automatic
performing a function without the necessity of intentional intervention
3.5
automatic/manual switch
means of converting the system from automatic to manual actuation
NOTE This may be in the form of a manual switch on the control panel or other units, or a personnel door interlock. In
all cases, this changes the actuation mode of the system from automatic and manual to manual only or vice versa.
3.6
clearance
3.6.1
electrical clearance
unobstructed air distance between extinguishing system equipment and unenclosed or uninsulated live
electrical components not at ground potential
3.6.2
thermal clearance
air distance between a condensed aerosol generator and any structure or components sensitive to the
temperature developed by the generator
3.7
competent person
designated person, suitably trained, qualified by knowledge and practical experience and with the necessary
instructions to enable the required tests and examinations to be carried out
3.8
