Overview

prEN 12845-1 is a CEN draft European standard for fixed firefighting systems - automatic sprinkler systems (Part 1: Design, installation and maintenance). It specifies requirements for the design, installation and maintenance of new automatic sprinkler systems and for additions, extensions, repairs or modifications of existing systems. The standard is intended for use across CEN member states, though national regulations may take precedence; users should confirm applicability with their national authorities.

Key topics and technical requirements

This standard covers the full lifecycle of an automatic sprinkler system with focus on safety, reliability and regulatory compliance. Major technical topics include:

  • Fire hazard classification (storage and non-storage occupancies) and the methodology for assigning design hazards.
  • Hydraulic design criteria and compartment design approaches for sprinkler performance.
  • Pipe sizing, layout and hydraulic calculations to ensure adequate water flow and pressure.
  • System types and installation methods: wet pipe, dry pipe, pre-action and other installation types.
  • Sprinkler components and design characteristics: sprinkler types, thermal sensitivity, spacing, coverage area, guards and corrosion protection.
  • Protection of special hazards: flammable liquid storage, aerosol containers, in-rack storage, car stackers, high-rise and residential specifics.
  • Valves, pipework and pipe supports, including underground and above-ground piping considerations.
  • Alarms, monitoring and transmission: water flow alarms, electrical switches, fire brigade connections and signal conditions.
  • Water supplies and pump-house requirements, including storage, maximum pressures and test facilities.
  • Contract planning, documentation and maintenance requirements, including design stage deliverables, block plans, signs and record-keeping.

Applications and practical value

prEN 12845-1 is practical for ensuring consistent, auditable design and performance of automatic sprinkler systems across a wide range of buildings and occupancies:

  • Industrial warehouses and high-hazard storage facilities
  • Manufacturing plants and special hazards installations
  • Commercial buildings, office complexes and residential/high-rise properties
  • Parking structures and automatic car stackers
  • Facilities requiring integration with building fire detection and remote monitoring

Using this standard helps design and installation teams achieve compliant hydraulic performance, reliable alarm transmission and maintainable systems that meet stakeholder, insurer and authority expectations.

Who uses this standard

  • Fire protection and sprinkler system designers
  • Building services and mechanical engineers
  • Installation contractors and commissioning teams
  • Facility managers and maintenance crews
  • Insurance assessors and authorities having jurisdiction (AHJs)

European foreword
This document (prEN 12845-1:2021) has been prepared by Technical Committee CEN/TC 191 “Fixed
firefighting systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12845:2015.
This document is included in a series of European standards:
CEN/TS 14816, Fixed firefighting systems - Water spray systems - Design, installation and maintenance;
CEN/TS 17551, Fixed firefighting systems — Automatic sprinkler systems — Guidance for earthquake
bracing
EN 671 (all parts), Fixed firefighting systems - Hose systems;

EN 17451, Fixed firefighting systems - Automatic sprinkler systems - Design, assembly, installation and
commissioning of pump sets.
The built environment continuously evolves. So do the fire protection challenges faced. This edition of
EN 12845 is a substantial revision. The objectives of the revision were to:
 provide the European market and users of EN 12845 with the most up to date and state of the art
sprinkler technologies; and
 preserve the excellent levels of performance (availability, reliability, and maintainability) of
automatic fire sprinkler systems.
The expert group responsible for drafting EN 12845 draw their expertise and knowledge from global fire
protection practices. Research and emerging best practice from around the world have been utilised in
this update.
The bibliography of this document identifies some of the sources of knowledge and research drawn upon
in the preparation of this document, and other sources of useful information in the sector. This list is not
intended to be exhaustive.
In comparison with the previous edition, the following technical modifications have been made:
 the sequence of clauses has been revised to reflect the flow of work in the design and installation of a
sprinkler system;
 a new approach to hazard classification has been introduced to reduce the number of classifications,
give more guidance for common hazards and to assist designers to determine the correct hazard
classification;
 hazard classification has been separated from hydraulic design criteria to allow for more than one
design approach for each hazard classification and to incorporate additional solutions;
 new names have been introduced for the hazard classifications;
 additional design options have been added for many hazard classifications to offer more flexibility
and to introduce new technology;
 the design criteria for storage protection have been updated;
 new design criteria for sprinkler systems under high ceilings have been added;
 new design criteria to take account of the effect of combustible construction on sprinkler system
performance have been added;
 some previous annexes have been incorporated in the body of the standard;
 ESFR and CMSA solutions were separated into a second part;
 pre-calculated systems were consolidated into an annex;
 furthermore, considering the changes in fire risk profiles introduced by the extensive use of plastics
in many industrial manufacturing processes, in the building construction components as well as in
the packaging of goods, this revision has introduced special considerations to reflect these challenges
in the sprinkler protection design.

Introduction
This document covers the classification of hazards, provision of water supplies, components to be used,
installation and testing of the system, maintenance, and the extension of existing systems, and identifies
construction details of buildings which are the minimum necessary for satisfactory performance of
automatic sprinkler systems. CMDA design approaches are covered in this document, while design
approaches for ESFR and CMSA designs are in EN 12845-2, which is to be used in conjunction with
EN 12845-1.
Sprinkler systems according to this document provide protection of life and property, and mitigate
business interruption.
An automatic sprinkler system is designed to detect a fire and extinguish it with water in its early stages
or hold the fire in check so that extinguishment can be completed by other means. An automatic sprinkler
system consists of a water supply (or supplies) and one or more sprinkler installations; each installation
consists of a set of installation main alarm valves and a pipe array fitted with sprinkler heads. The
sprinkler heads are fitted at specified locations at the roof or ceiling, and where necessary between racks,
below shelves, and in ovens or stoves. The main elements of a typical installation are shown in Figure 1.

3 riser (see 3.83) 7 range pipe (see 3.82)
4 distribution pipe (see 3.31) 8 automatic sprinkler (see 3.84)
Figure 1 — Main elements of a sprinkler installation
The sprinklers operate at predetermined temperatures to discharge water over the affected part of the
area below. The flow of water through the alarm valve initiates a fire alarm. The sprinkler operating
temperature is generally selected to suit ambient temperature conditions.
Only sprinklers in the vicinity of the fire, i.e. those which become sufficiently heated, operate. The
sprinkler system is intended to extend throughout the premises with only limited exceptions.
In some applications additional measures to improve automatic sprinkler system reliability and
availability may be specified, such as where the automatic sprinkler system is part of the measures
designed to maintain safe conditions during evacuation.
It should not be assumed that the provision of an automatic sprinkler system eliminates the need for
other means of fighting fires and it is important to consider the fire precautions in the premises as a
whole.
Structural fire resistance, escape routes, fire detection and fire alarm systems, particular hazards needing
other fire protection methods, provision of hose reels and fire hydrants and portable fire extinguishers,
etc., safe working and goods handling methods, management supervision and good housekeeping all need
consideration.
Automatic sprinkler systems should be properly maintained to ensure they operate when required. This
routine is liable to be overlooked or given insufficient attention by supervisors. 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 proper maintenance cannot be too highly emphasised.
This document is intended for use by those concerned with purchasing, designing, installing, testing,
inspecting, approving, operating and maintaining automatic sprinkler systems, in order that such a
system will function as intended throughout its life.
It is a basic assumption that this standard is for the use of companies employing personnel competent in
the field of application with which it deals. Only trained and experienced personnel should undertake the
design, installation and maintenance of sprinkler systems (see 3.152). Similarly, competent technicians
should be used in the installation and testing of the equipment.
Research periodically leads to the introduction of new sprinkler concepts. Authorities may accept these
new sprinkler systems if they are satisfied that there is sufficient evidence that they offer equivalent or
better performance and reliability to the technology in this standard.
