Emergency and Hazard Response System
An Emergency and Hazard Response System (NGRS) can be used for various types of applications, e.g. B. emergency ( amok - or threat alarm), house alarm, de-escalation call and call for help, if necessary with voice communication as well as for alarming (z. B. confinement alarm) or for providing information. NGRS are primarily for use in public buildings. such as educational institutions (e.g. schools, universities), authorities, kindergartens and similar institutions. However, they can also be used in non-public buildings with a similar risk and need for protection. The task of NGRS is to make an uncomplicated emergency call in the event of an emergency and to provide help quickly. For this purpose, the system records events (emergency and hazard reports) and forwards them to an appropriate recipient so that assistance can be provided in a suitable manner. By acknowledging the receipt, an auxiliary body takes responsibility for the emergency. NGRS also serve to meet the requirements of the Occupational Safety and Health Act, in particular the protection of life and limb of staff and all people in the building, taking into account the inclusion of people with disabilities.
Norms
The pre-standard DIN VDE V 0827 "Emergency and Hazard Systems - Part 1: Emergency and Hazard Response Systems (NGRS)" shows the basic requirements, tasks, responsibilities and activities. The prestandard is aimed in particular at the police , insurers, planners, architects, manufacturers and specialist companies of security systems as well as builders, owners, operators, users and residents of endangered objects (especially public buildings such as educational institutions, authorities, kindergartens and similar institutions). It describes the process of creating, maintaining and updating a risk management file in which, among other things, the technical risks are listed, assessed and residual technical risks are defined, from which the degree and structure of the NGRS result. Furthermore, the prestandard provides useful information for organizational risk management and interaction with technical risk management. The preliminary standard is also intended to support the implementation of legal and other requirements (e.g. Equal Opportunities for People with Disabilities Act, Occupational Safety and Health Act, Occupational Safety and Health Ordinance, federal state school laws, federal state regulations on supervisory obligations). On the basis of a systematic risk assessment, a risk determination with subsequent risk analysis and a risk assessment must first be carried out as part of the risk management process. The entirety of the organizational, personnel, technical and structural measures to secure an object must be considered. On the basis of this and the information about the building use, risk factors and protection goals, a comprehensive security concept must be drawn up, which aims to avoid or reduce threats and damage to people or property. Based on the risk assessment and the definition of the residual risk, the pre-standards provide technical specifications for planning, installation, operation and maintenance of an NGRS in three different degrees of security. For this purpose, the standard shows, among other things, the responsibilities and above all the activities of a technical risk manager to be employed. In addition, the structure and content of a technical risk management file is described. The second part of the DIN VDE V 0827 series shows additional requirements for emergency and danger intercom systems (NGS). It specifies the basic requirements for emergency and danger intercom systems (NGS) that are used as emergency and danger response systems (NGRS) in accordance with DIN VDE V 0827-1 (VDE V 0827-1). A third part with application rules, such as the content and structure of the risk management file as well as examples from NGRS is currently already available as a draft version.
Norm vs. Pre-standard
The DIN VDE V 0827 series of standards are referred to as pre-standards as long as they have not yet been adopted as a harmonized European standard (EN). After three years at the latest, it is checked annually whether it can be converted into a harmonized European standard. The standards committee DKE / UK 713.1 "Hazard reporting and monitoring systems" of the DKE German Commission for Electrical, Electronic and Information Technologies in DIN and VDE is responsible for the DIN VDE V 0827 series of standards .
Standards are recommendations, so there is basically no obligation to adhere to them. However, they are so-called recognized rules of technology, i.e. a technical specification that is viewed by a majority of representative experts as a representation of the state of the art. Therefore, they are consulted by appropriate experts in problem cases and disputes.
As part of the European standardization of standards, new national standards in Germany are usually only issued as pre-standards (see CEN / CENELEC internal regulations Part 2, Paragraph 5 and the standstill agreement anchored there), which is why the NGRS standards were also issued as pre-standards . In principle, the necessary experience should first be gathered by applying a prestandard.
A prestandard can, however, acquire the status of a recognized rule of technology if there is no other set of rules on this matter and there are no negative experiences in its application or if it is viewed by a majority of representative experts as a representation of the state of the art. In the case of the NGRS pre-standards, this is likely due to the versatile application and implementation in specific regulations, such as B. in the ÜEA guideline, now be the case.
If emergency and hazard systems are to be used, the generally recognized rules of technology must be observed, which is why it is recommended that the standards and pre-standards be applied to corresponding systems.
Alarm triggering devices
Emergency and hazard detectors (NGRS detectors) in accordance with DIN VDE V 0827-1 are used to manually trigger an alarm message in the event of an acute emergency or danger (e.g. amok).
In grade 1, pure push-button alarms are permitted as NGRS alarms. So-called wireless personal emergency signal systems for solo work in accordance with DIN VDE V0825 may also be used as portable NGRS detectors in grade 1 and 2 under certain conditions.
From grade 2, however, direct verification in the form of data or voice communication between the initiator and the person providing assistance must be possible for verification, whereby voice communication must be present in grade 3.
Alarm
The on-site alarm is issued as a so-called internal alarm, which is used to warn people present in accordance with the stipulations in the risk management file. These can be acoustic signals or voice announcements. The alarm is forwarded via remote alarm systems to an auxiliary point (e.g. an emergency call and service control center ).
In justified cases, the NGRS can also be connected directly to the police in coordination with the police . This must be carried out analogously to the ÜEA guideline . In this case, the police must be involved in planning the NGRS at an early stage.
