European foreword
This document (EN 50726-1:2024) has been prepared by CLC/TC 79 “Alarm systems”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2025–04–15
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2027–04–15
conflicting with this document have to be
withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national committee. A complete

Introduction
This document is based on draft standard E DIN VDE V 0827-1 (VDE V 0827-1):2015-04.
National working body UK 713.1 “Alarm and surveillance systems” of DKE German Commission for Electrical,
Electronic and Information Technologies of DIN and VDE (www.dke.de) is responsible for the present document.
A pre-standard is the result of standardization work that has not yet been published as a standard by DIN due
to certain reservations with regard to the contents or because of its deviating preparation procedure.
The present pre-standard has become necessary because:
a) the field of emergency and danger response systems (EDRS) is becoming increasingly important;
b) all existing standards and guidelines in the field of alarm system technology apply to specific use cases
such as intrusion alarm technology or fire alarm technology, etc.
This standard is aimed in particular at the police, insurance providers, planners, architects, manufacturers and
expert companies dealing with safety/security systems, as well as builders, owners, organization in charges,
users and occupants of properties at risk (in particular public buildings such as education facilities, agencies,
nursery schools and similar facilities).
An EDRS can never replace the detection or alarm function of a fire detection and fire alarm system, voice alarm
system, or intrusion/hold-up alarm system (I&HAS). The alarming must always be done by the appropriate alarm
system and alarm transmission system. The EDRS has only the function of additional measures.
1 Scope
This document applies to the planning, installation, commissioning, operation and maintenance of an
emergency and danger response system. An emergency and danger response system is part of an overall
solution for dealing with specific events such as emergencies or crises.
This document
• specifies:
• technical processes and responsibilities for supporting all procedures from the registration of an event
(emergency, danger) up to its final processing;
• the technical risk management including the definition of safety/security goals and the workflow
organization as well as the necessary specifications regarding a technical risk management file;
• associated duties, responsibilities and activities as parts of an integrated overall risk management
process to achieve the safety and security goals, effectiveness and efficiency as well as data and
system safety/security;
• three different grades of safety/security, with the respective product functionalities required to achieve
them;
• the basic requirements for emergency and danger response systems (EDRS) in public buildings such
as education facilities (e.g. schools, universities), government facilities, kindergartens and similar
facilities;
• the responsibilities under applicable national law about Safety and Health at Work Laws and thus
particularly addresses the responsibility of employers;
• describes:
• the process of establishing, maintaining and updating a risk management file in which, inter alia, the
technical risks are listed and evaluated and the residual technical risks are defined, resulting in the
grade and structure of the EDRS;
• is intended to support the implementation of:
• National legal and other provisions (e.g. Act on Equal Opportunities for People with Disabilities, Safety
and Health at Work Laws, education laws);
• gives relevant guidance on:
• the organizational risk management;
• does not replace the specifications of standards to the following systems:
• fire safety systems including, but not limited to, fire detection and fire alarm systems, fixed firefighting
systems, smoke and heat control systems,
• security systems including, but not limited to, intrusion and hold-up alarm systems, electronic access
control systems, external perimeter security systems and video surveillance systems,
• applicable national standards on call systems.
All such systems can, however, be integrated into an emergency and danger response system (EDRS), taking
into account the relevant provisions made in the respective standards for such products and systems.
Other products and systems from the entire field of standardization, such as alarm systems, danger warning
and danger alarm systems, escape routing systems, public address systems used to respond to a danger, can
also be used in or integrated into an emergency and danger response system if the relevant requirements of
the standards for such products or systems are met.
This document does not specify any risk levels, in particular no acceptable residual risks. Technical risk
management and organizational risk management are equal parts of the overall risk management.
This document is also applicable to non-public buildings with a similar risk and requirement for protection.

4 Requirements for an EDRS
4.1 General
An EDRS is used to receive events (emergency and danger warning messages), to forward them to a technical
receiver and to present them in a suitable manner to an assistance provider. By acknowledging the receipt, the
assistance provider assumes responsibility for verification and the initiation of defined measures in accordance

damages to people and objects. It shall contain all specified organisational, staff-related, technical and
constructional measures applied to protect a property and to avert dangers. Therefore, information shall be
given at least on the use of the building, the risk to the property, the safety/security objectives of the EDRS such
as personal and/or property protection, the areas to be monitored using automatic alarm devices, the non-
automatic alarm devices to be actuated by individuals, on control functions which might be present, personal
safety/security measures, alarm devices and alarm areas and on assistance providers.
The set-up and operation of an EDRS requires technical risk management during the entire life cycle of the
EDRS. Considerations concerning the life cycle of an EDRS are part of the technical risk management file.
It is the responsibility of the technical risk management to be appointed to specify the system r
