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.
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 7240-11 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 3, Fire detection and fire alarm systems.

Introduction
This part of ISO 7240 has been prepared up by Sub-Committee ISO/TC 21/SC3, the secretariat of which is
held by SAI and is based on a European Standard EN 54-11 prepared by the European Committee for
Standardization CEN/TC 72 “Fire detection and fire alarm systems”.
This part of ISO 7240 has been drafted on the basis of appearance and functions which should be provided
on all manual call points for use in fire detection and fire alarm systems. The colours, dimensions, shapes and
methods of operation are based on recognised operating principles which give confidence and recognition to
the user when operated in genuine fire alarm situations.
It is important for manual call points to be recognisable and simple to use, without the need to read elaborate
instructions so that anyone discovering a fire is able to use the manual call point without previous familiarity
with it.
The purpose of a manual call point is to enable a person discovering a fire to initiate the operation of a fire
alarm system so that appropriate measures can be taken.
The intention of this International Standard is to specify requirements for operation and reliability. The
methods of operation of the manual call points covered are as follows:
⎯ Type A: direct operation (single action);
⎯ Type B: indirect operation (double action).
Both types require the breaking or the visible displacement by change of the position of a frangible element
forming part of the front face, which is considered to be the most suitable method for general application and
which act as a deterrent to the misuse of the device.
Importance has been placed on identifying the manual call point, the method by which it is activated and an
indication to the user that the initiation of an alarm has been given.
The resulting standard takes into account national variances in custom and practice and language in bringing
together common elements that contribute towards a standard device for use throughout the world.
The performance of manual call points is assessed from results obtained in specific tests. This part of
ISO 7240 is not intended to place any other restrictions on the design and construction of such manual call
points.

Fire detection and alarm systems —
Part 11:
Manual call points
1 Scope
This part of ISO 7240 specifies the requirements, test methods and performance criteria for manual call points
in fire detection and alarm systems in and around buildings (see ISO 7240-1). It takes into account indoor and
outdoor conditions, the appearance and operation of the manual call points for type A “direct operation” and
type B “indirect operation” and covers those which are simple mechanical switches, those which are fitted with
simple electronic components (e.g. resistors, diodes) and those which contain active electronic components
and which work with the control and indicating equipment for signalling and identifying, for example, an
address or location.
This part of ISO 7240 does not cover manual call points for special applications, for example manual call
points that are intrinsically safe or for use in hazardous conditions, if such applications require additional or
other requirements or tests than those given in this standard.
