Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR 7240-14 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire
fighting, Subcommittee SC 3, Fire detection and alarm systems.
ISO/TR 7240 consists of the following parts, under the general title Fire detection and alarm systems:
 Part 1: General and definitions
 Part 2: Control and indicating equipment
 Part 4: Power supply equipment
 Part 5: Point-type heat detectors
 Part 6: Point-type fire detectors for detection of carbon monoxide
 Part 7: Point-type smoke detectors using scattered light, transmitted light or ionization
 Part 11: Manual call points
 Part 14: Guidelines for drafting codes of practice for design, installation and use of fire detection and fire
alarm systems in and around buildings [Technical Report]
 Part 15: Point-type multisensor (light and heat) fire detectors
Compatibility assessment of system components and carbon monoxide point-type fire detectors using
electrochemical cells are to form the subjects of future Parts 13 and 16.

Introduction
The installation of a fire detection and fire alarm system can only be successfully accomplished if the following
conditions are fulfilled:
 materials are of a suitable quality;
 special knowledge in the field of fire detection;
 skilled personnel to carry out the work.
Although the quality of the material can be ensured by proper standards and quality audits, the overall
effectiveness of an installation depends widely on the quality of work and the experience of the designer and
installer.
The general purpose of a code of practice is to give recommendations that are the result of knowledge and
experience in order to share the learning with other stakeholders.
From the objectives of a code of practice, it follows that it must be continuously adapted to incorporate new
experiences, otherwise a code could block the progress or the introduction of new technologies.
In the past, most industrialized countries have developed codes of practice. However, they differ from each
other because they reflect the experience made in the respective country. Due to these differences, it is not
possible to write an international code of practice. Therefore, ISO/TC21/SC3 proposes to use these guidelines
with the following objectives:
 development of national codes of practice in countries which do not yet have such a code;
 redraft existing codes using the proposed format in order for them to be more consistent.
The table of contents is structured in such a way that the different phases during the life of the fire detection
and fire alarm system are dealt with in separate clauses starting with the planning phase. The importance of
clear assignments of responsibilities and of documentation is emphasized by dedicated clauses.
It is not the intent of this document to restrict the content of any national code to those clauses given. However,
since one of the intentions of this document is to allow easier comparison between codes from different
countries, the clause numbering should generally be followed. Where a country has no requirements under
the heading given in the document, then it is recommended that the clause be inserted with the comment “No
requirements”.
The object should be defined for each clause to avoid misinterpretations.

Guidelines for drafting codes of practice for design, installation
and use of fire detection and fire alarm systems in and around
buildings
1 Scope
This Technical Report is intended to be used as a general guideline for the preparation of a code of practice
for the design, installation and use of a fire detection and fire alarm system.
It describes the format, the table of contents and the objectives of the different clauses of the code of practice.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 7240-1, Fire detection and alarm systems — Part 1: General and definitions
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 7240-1 and the following apply.
3.1

Table 1 — Content of code of practice
Number Clause Subclause sub subclause Explanation or recommended text
1 Scope  This standard provides recommendations for the
planning, design, installation, commissioning and
servicing of manual and automatic fire detection and
fire alarm systems in and around buildings.
It also covers systems capable of providing signals to
initiate the operation of ancillary technical services,
such as fixed fire extinguishing systems and other
precautions and actions.
2 Terms and  Definitions for all technical terms that are used in this
definitions standard so far as they are needed for a clear
understanding.
Definitions of terms that are already defined in other
standards for components of fire detection systems
shall be used.
3 Normative  An overview of all standards and relevant documents
references that have to be considered.
4 Design  Allows for the introduction of national requirements for
requirements the general design of systems. Examples of subjects
which could be covered are:
 restrictions on the number of detectors to be
connected to one circuit;
 requirements for provisions for testing;
 special requirements for circuits having both
detectors and alarm devices;
 special requirements for the combination of
initiating and indicating circuits;
 use of special installation material, e.g. shielded
cable, conduits.
5 Planning
5.1 Planning Responsibilities A written assignment of responsibilities for the whole
phase of planning a fire detection and fire alarm system
is recommended. A document shall be signed by a
responsible person describing the field of responsibility
in such detail that undefined areas and overlapping
