Fire detection and alarm systems - Part 11: Manual call points

ISO 7240-11:2011 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. ISO 7240-11:2011 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 ISO 7240-11:2011.

Overview

ISO 7240-11:2011 - "Fire detection and alarm systems - Part 11: Manual call points" defines the requirements, test methods and performance criteria for manual call points used in fire detection and alarm systems in and around buildings. It covers both simple mechanical devices and manual call points with electronic components (including addressable units that report location). The standard addresses indoor and outdoor conditions, user ergonomics (recognition and simple operation), and the essential safety feature of a frangible element. It does not cover special-purpose call points (for example intrinsically safe devices for hazardous atmospheres) that require additional testing.

Key topics and technical requirements

• Scope and device types
  • Type A: direct operation - alarm condition is triggered automatically when the frangible element is broken or displaced.
  • Type B: indirect operation - requires an additional manual action after the frangible element is broken.
• Frangible element definitions and options: resettable vs non‑resettable; intended to deter misuse and provide visible confirmation of activation.
• Marking and data: permanent identification requirements (including reference to ISO 7240-11:2011, manufacturer, model, environment category).
• Construction, indicators and reset/test facilities: visibility of alarm indication, reset/test provisions, design ergonomics and protection against unintended operation.
• Software-controlled devices: special requirements for manual call points that include embedded software or active electronics (see Clause 4.8).
• Testing and performance criteria (Clause 5): operational performance, function tests, endurance/reliability, variation of supply parameters, environmental testing (dry heat, cold, damp heat cyclic and steady, SO2 corrosion), shock, impact, vibration, EMC, enclosure protection, solar radiation exposure.
• Normative references: ISO 7240-1 (general definitions), relevant IEC 60068 environmental tests series, EN 50130-4 (EMC immunity) among others.

Practical applications and who uses this standard

• Manufacturers: to design and validate manual call points that meet international requirements for safety, durability and interoperability with fire alarm control equipment.
• Test laboratories and certification bodies: to perform the specified performance and environmental tests and produce compliance reports.
• System designers, specifiers and procurement teams: to reference ISO 7240-11:2011 in product specifications and tenders for fire detection and alarm systems.
• Installers and facility managers: to ensure correct selection (indoor/outdoor rating), installation, marking, accessibility and maintenance consistent with the standard.
• Regulators and code authors: to harmonize local fire safety regulations with international best practice.

Related standards

• ISO 7240 series (Part 1 - General and definitions; Part 2 - Control and indicating equipment; etc.)
• IEC 60068 series (environmental testing)
• EN 50130-4 (EMC immunity for alarm system components)

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.

Introduction
This part of ISO 7240 has been prepared by ISO/TC 21/SC 3, the secretariat of which is held by SA and is
based on ISO 7240-11:2005.
This part of ISO 7240 has been drafted on the basis of appearance and functions that 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 recognized operating principles that give confidence and recognition to the
user when operating in genuine fire alarm situations.
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.
It is important for manual call points to be recognizable and simple to use, without the requirement to read
elaborate instructions so that anyone discovering a fire is able to use the manual call point without previous
familiarity with it.
The intention of this part of ISO 7240 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 as the most suitable method for general application and
which acts 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 part of ISO 7340 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.

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
