Was versteht man unter GMA?

GMA ist die Abkürzung für den Begriff Gefahrenmeldeanlage. Das sind Alarmanlagen, die Gefahren wie z. B. Rauch, Feuer und Einbruch erkennen. Im Gefahrenfall können GMA (selbstständig) Hilfsstellen wie die Feuerwehr informieren. Sie werden auch genutzt, um beispielsweise Menschen gezielt aus einem Gebäude zu evakuieren.

Welche Gefahrenmeldeanlagen gibt es?

Es gibt die folgenden Arten von Gefahrenmeldeanlagen: Brandmeldeanlagen (BMA) erkennen rechtzeitig Rauch und Feuer, alarmieren anwesende Personen und die örtliche Feuerwehr. Sie steuern weitere Maßnahmen wie z. B. die Auslösung einer Löschanlage an. Brandwarnanlagen (BWA) informieren anwesende Personen akustisch und optisch zur Brandgefahr. Einbruchmeldeanlagen (EMA) schrecken Einbrecher frühzeitig ab oder Alarmieren im Gefahrenfall hilfeleistende Stellen wie den Wachdienst. Elektroakustische Anlagen (ELA) werden zur Evakuierung von Menschen genutzt. Das erfolgt durch gezielte Sprachdurchsagen, wie auch Alarmierung von hilfeleistenden Stellen. Ist eine ELA-Anlage mit einer BMA verbunden, spricht man von einer Sprachalarmierungsanlage (SAA). Weitere Varianten sind das Elektroakustische Notfallwarnsystem (ENA) wie auch das Notfall- und Gefahren-Reaktions-System (NGRS). Überfallmeldeanlagen (ÜMA) informieren die Polizei oder den Wachdienst bei einem Überfall.

Wie funktioniert eine Gefahrenmeldeanlage?

Unterschiedliche Warnmelder prüfen die Räumlichkeiten vor Ort auf mögliche Gefahren wie Feuer, Rauch, Einbruch usw. Diese Warnmelder senden regelmäßig den aktuellen Stand an die Zentraleinheit der Gefahrenmeldeanlage. Diese sammelt und wertet die Information aus und löst im Gefahrenfall Alarm aus.

Warum müssen die Übertragungswege einer Gefahrenmeldeanlage überwacht werden?

Wenn Übertragungswege einer Gefahrenmeldeanlage unterbrochen sind, kann die Gefahrenmeldeanlage nicht funktionieren, Menschen können somit nicht geschützt werden. Die Übertragungswege einer Gefahrenmeldeanlage können über Telefonleitungen, Funknetze oder Internetverbindungen erfolgen. Die Überwachung dieser Übertragungswege erfolgt über automatische Testanrufen, regelmäßige Funktionsprüfungen oder spezielle Überwachungsgeräte.

Was ist eine Gefahrenmeldeanlage 34a?

Das bezieht sich auf die Vorgaben des §34a der Gewerbeordnung. In diesem Paragrafen sind die Anforderungen festgelegt zu den Gewerbebetreibende, die Gefahrenmeldeanlagen errichten und betreiben.

Was gehört nicht zu den sogenannten Gefahrenmeldeanlagen?

Anlagen die Gefahrensituation selbst nicht erkennen, gehören nicht zu den Gefahrenmeldeanlagen. Dazu zählen Videoüberwachungsanlagen, Zutrittskontrollsysteme, Brandbekämpfungssysteme (Feuerlöscher) wie auch Notbeleuchtungssysteme.

Hazard detection system - advice, installation & maintenance

Hazard detection systems contribute significantly to the safety of people and buildings. They detect hazardous situations such as fire, smoke development, gas leaks or burglary. These include house alarm and fire warning systems as well as fire alarm systems that detect smoke and fire at an early stage, trigger the alarm and activate further protective measures. Electroacoustic systems support the evacuation of people. Burglar alarm systems act as a deterrent and the measures taken reduce the damage.

Rapid help thanks to hazard detection systems

Damage limitation

Early warning systems detect fires and burglaries in their early stages and thus ensure that damage is kept to a minimum.

Targeted alerting

In case of danger, persons present can be alerted immediately and evacuation measures can be initiated.

Report to aid agencies

Manual or automated information can be sent to emergency services such as the gatekeeper, security service or fire brigade.

Initiation of protective measures

Protective measures can be initiated manually or automatically, including, for example, the activation of extinguishing systems, the opening of smoke extraction systems or voice alarms with safety instructions.

Hazard detection systems for your safety

CWS offers you various hazard detection systems from renowned manufacturers.

Functionality of a hazard detection system

Warning detectors of a hazard detection system check the premises for hazards. Smoke detectors check the air for smoke particles. Motion detectors monitor the room and sound the alarm in case of movement.

Warning detectors send the current status to the central unit of the hazard detection system. The central unit receives and processes the information from the warning detectors. In case of danger, the central unit of the hazard detection system triggers measures. This includes the alerting of persons present or assistance agencies (security, fire brigade, police) as well as the activation of further systems (e.g. extinguishing system). The hazard detection system and its electronic cables must be separately protected from fire and heat so that the hazard detection system continues to function in the event of fire.

The DIN VDE 0833 standard specifies the minimum requirements for a hazard detection system. This includes the planning, installation, operation, maintenance and testing of hazard detection systems. Compliance with the requirements of DIN VDE 0833 ensures that hazard detection systems meet the current technical standard and thus guarantee a high level of reliability and safety.

Step by step to the hazard detection system

The installation of hazard detection systems is based on requirements imposed by authorities, insurance companies or on a voluntary basis. The following steps are necessary before the hazard detection system can be put into operation:

Record the requirements for the hazard detection system. This is based on the building permit, insurance requirements or individual protection goals.
Inspection of the on-site conditions and exchange of information on the protection goals.
Planning of the hazard detection system with all components.
Installation of the hazard detection system and preparation for acceptance (incl. trial operation).
Acceptance of the hazard detection system by a certified body.
Instruction in the operation of the hazard detection system, as well as handing over all documentation.

Maintenance of hazard detection systems

Depending on the type of hazard alarm system, there are different specifications for maintenance and inspection.

House alarm system: annual maintenance
Fire alarm system: quarterly inspection and annual maintenance
Electro-acoustic system: one inspection per quarter and annual maintenance.
Burglar alarm system: one inspection per quarter and annual maintenance.

Questions and answers about hazard detection systems

What is HDS?

HDS is the abbreviation for the term hazard detection system. These are alarm systems that detect dangers such as smoke, fire and burglary. In the event of danger, alarm systems can (independently) inform emergency services such as the fire brigade. They are also used, for example, to evacuate people from a building.

What hazard detection systems are there?

There are the following types of hazard detection systems:

Fire alarm systems detect smoke and fire in time, alert persons present and the local fire brigade. They trigger further measures such as the activation of an extinguishing system.
Fire warning systems inform people present acoustically and visually of the fire hazard.
Burglar alarm systems deter burglars at an early stage or alert emergency services such as the security service in case of danger.
Electroacoustic systems) are used to evacuate people. This is done by targeted voice announcements as well as by alerting emergency services. If an ELA system is connected to a fire alarm system, it is called a voice alarm system. Other variants are the electroacoustic emergency warning system and the emergency and danger response system.
Hold-up alarm systems inform the police or the guard service in the event of a hold-up.

How does a hazard detection system work?

Different warning detectors check the premises on site for possible hazards such as fire, smoke, burglary, etc. These warning detectors regularly send the current status to the central unit of the hazard detection system. The central unit collects and evaluates the information and triggers an alarm in case of danger.

Why must the transmission paths of a hazard detection system be monitored?

If transmission paths of a hazard detection system are interrupted, the hazard detection system cannot function and people cannot be protected. The transmission paths of a hazard detection system can be via telephone lines, radio networks or internet connections. These transmission paths are monitored via automatic test calls, regular function tests or special monitoring devices.

What is a hazard detection system 34a?

This refers to the requirements of §34a of the Trade, Commerce and Industry Regulation Act. This paragraph sets out the requirements for tradespeople who set up and operate hazard detection systems.

What does not belong to the so-called hazard detection systems?

Systems that do not detect the danger situation themselves are not classified as hazard detection systems. These include video surveillance systems, access control systems, fire fighting systems (fire extinguishers) as well as emergency lighting systems.
