Thank you for your interest in HÖRMANN Warnsysteme GmbH.

www.hoermann-ws.de is the joint website for the HÖRMANN Group. Under an arrangement on joint control (Art. 26 GDPR), HÖRMANN Holding GmbH & Co. KG complies with the data privacy obligations of the General Data Protection Regulation (GDPR) for this website. In this data privacy policy, the term “we” includes all affiliated companies of the HÖRMANN Group. However, HÖRMANN Holding GmbH & Co. KG complies with the data privacy obligations under the GDPR and hence is your point of contact at all times. Contact details can be found in section 2 below.

Data privacy is a particular priority for the HÖRMANN Group.

As a matter of principle, you can use the website without disclosing any personal data. If a data subject wishes to use our services via the website, this may necessitate the processing of personal data. If the processing of personal data is necessary and there is no legal basis for such processing, we always obtain the consent of the data subject.

Personal data (e.g. the name, address, e-mail address or telephone number of a data subject) is always processed in accordance with the GDPR and the national data privacy provisions applicable to us, particularly the German Federal Data Protection Act (BDSG).
This data privacy policy is intended to inform the public about the nature, extent and purpose of the personal data collected, used and processed by us. This data privacy policy also informs data subjects about their rights.

As the processor, we have taken numerous technical and organisational measures to ensure that the personal data processed via the website is protected to the greatest possible extent.

As a matter of principle, however, data transmission via the Internet can be subject to security flaws. As such, complete protection cannot be guaranteed. Needless to say, all data subjects may transmit personal data to the company by alternative means, e.g. by telephone.
 

1. Definitions

This data privacy policy is based on the definition used by the European regulator in issuing the GDPR. The data privacy policy should be easy to read and easy to understand for all users. Accordingly, the data privacy policy begins by explaining the definitions used. Among other things, this data privacy policy uses the following definitions:

  • ‘personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person;
  • ‘data subject’ means any identified or identifiable natural person whose personal data is processed by the controller.
  • ‘processing’ means any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction;
  • ‘restriction of processing’ means the marking of stored personal data with the aim of limiting their processing in the future;
  • ‘profiling’ means any form of automated processing of personal data consisting of the use of personal data to evaluate certain personal aspects relating to a natural person, in particular to analyse or predict aspects concerning that natural person’s performance at work, economic situation, health, personal preferences, interests, reliability, behaviour, location or movements;
  • ‘controller’ means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by Union or Member State law, the controller or the specific criteria for its nomination may be provided for by Union or Member State law;
  • ‘recipient’ means a natural or legal person, public authority, agency or another body, to which the personal data are disclosed, whether a third party or not. However, public authorities which may receive personal data in the framework of a particular inquiry in accordance with Union or Member State law shall not be regarded as recipients; the processing of those data by those public authorities shall be in compliance with the applicable data protection rules according to the purposes of the processing;
  • ‘third party’ means a natural or legal person, public authority, agency or body other than the data subject, controller, processor and persons who, under the direct authority of the controller or processor, are authorised to process personal data;
  • ‘consent’ of the data subject means any freely given, specific, informed and unambiguous indication of the data subject’s wishes by which he or she, by a statement or by a clear affirmative action, signifies agreement to the processing of personal data relating to him or her.
  •

4. Erasure and blocking of personal data

We process and store the personal data of the data subject only for the period required to achieve the purpose of storage or for the statutory storage period that the controller is obliged to observe under the applicable legislation.

If the purpose of storage no longer applies or a statutory storage period expires, the personal data is routinely blocked or erased in accordance with the statutory provisions.
 

5. Collection and storage of personal data and type and purpose of its use

a) when visiting the website

As a matter of principle, you can use this website without disclosing your identity. When you access the website, the browser used on your device automatically sends information to the website server. This information is stored temporarily in a log file. The following information is recorded without any action on your part and until erased automatically:

  • IP address of the accessing computer,
  • date and time of the access,
  • name and URL of the file retrieved,
  • website from which the website was accessed (referrer URL),
  • browser used and, where applicable, the operating system of your computer and the name of your access provider.

The company processes this data for the following purposes:

  • to ensure the connection to the website is established smoothly,
  • to ensure the website is convenient to use,
  • to evaluate system security and stability, and
  • for other administrative purposes.

The legal basis for data processing is Art. 6 (1) sentence 1 (f) GDPR. The legitimate interest of the company is based on the aforementioned data collection purposes. We never use the data collected to identify you. The data is erased after no more than 14 days.

We also use cookies and analytics services when you visit the website. Further details can be found in sections 9 and 11 of this data privacy policy.

b) when using the contact form or contacting us by e-mail

If you have any type of questions, we offer you the possibility of contacting the company using a contact form on the website or by e-mail. You must enter a valid e-mail address in order for us to know who sent the enquiry and be able to reply to it. All other disclosures are voluntary. It is up to you whether you submit this data using the contact form or by e-mail.

The data submitted is processed in order to handle your enquiry. The data is erased immediately after your enquiry has been handled unless it is subject to a statutory retention period.

The legal basis for data processing is Art. 6 (1) sentence 1 (b) GDPR if the enquiry is necessary for the performance of a contract or to take steps prior to entering into a contract, Art. 6 (1) sentence 1 (c) GDPR in the case of statutory retention periods, and otherwise legitimate interest in accordance with Art. 6 (1) sentence 1 (f) GDPR. We have a legitimate interest in processing your enquiry in order to provide you with the best possible service even if it is not necessary for the performance of a contract or to take steps prior to entering into a contract.

The data is processed solely in order to reply to your enquiry and stored for the duration of the statutory retention period (6 years in accordance with section 257 (1) no. 2, (4) of the German Commercial Code (HGB)) if it constitutes commercial letters. The data is otherwise erased immediately after your enquiry is replied to.
 

6. Additional information on the legal basis of processing

Art. 6 (1) (a) GDPR serves as the legal basis for processing where consent is required to be obtained for a certain processing purpose. If processing of personal data is necessary for the performance of a contract to which the data subject is party, the legal basis for processing is Art. 6 (1) (b) GDPR. The same applies for processing in order to take steps at the request of the data subject prior to entering into a contract, e.g. enquiries about products and services. If we are subject to a legal obligation to process personal data, the legal basis for processing is Art. 6 (1) (c) GDPR. In rare cases, processing of personal data may be necessary in order to protect the vital interests of the data subject or of another natural person. In this case, the legal basis for processing is Art. 6 (1) (d) GDPR. The legal basis for processing may also be Art. 6 (1) (f) GDPR if processing is not covered by one of the aforementioned legal bases but is necessary for the purposes of the legitimate interests perused by us or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject. In particular, such processing is permitted because it is specifically mentioned by the European legislator (see Recital 47 sentence 2 GDPR).
 

7. Consideration of legitimate interests

If the legal basis for processing personal data is Art. 6 (1) (f) GDPR, our legitimate interest is the performance and fulfilment of business activities to the benefit of our employees and shareholders.

10. Google Analytics

This website uses Google Analytics, a web analytics service provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”). Google Analytics uses cookies, which are text files that are stored on your computer and that enable the analysis of your use of the website. The information generated by the cookie on your use of this website is typically transmitted to a Google server in the USA and stored there. Please note that Google Analytics has been extended on this website to include the “anonymizeIP” code in order to ensure that IP addresses are recorded anonymously (IP masking). This means that your IP address is abbreviated in Member States of the European Union or in other Contracting States to the Agreement on the European Economic Area prior to being transmitted to the USA. The full IP address is transmitted to a Google server in the USA and abbreviated there only in exceptional cases. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, compile reports on the website activities and perform other services in connection with website use and Internet use for the website operator. The IP address transmitted by your browser for the purposes of Google Analytics is not combined with other Google data. You can configure your browser software to reject the storage of cookies; however, please note that this may mean you are unable to use all of the functions of this website in full. You can also prevent the data generated by the cookie relating to your use of the website (including your IP address) from being recorded and processed by Google by downloading and installing the browser plug-in that can be accessed at the following link (http://tools.google.com/dlpage/gaoptout?hl=de).

You can prevent data from being recorded by Google Analytics by clicking the following link. This will set an opt-out cookie that prevents your data from being collected when visiting this website in future: Deactivate Google Analytics

11. Social media plug-ins

We use plug-ins for social networks (e.g. Facebook, Twitter, Google+) on the website on the basis of Art. 6 (1) sentence 1 (f) GDPR in order to increase awareness of the company via these channels. The underlying commercial purpose constitutes a legitimate interest within the meaning of the GDPR. Responsibility for operation in compliance with data privacy legislation must be ensured by the respective provider. The company integrates these plug-ins using the two-click method in order to protect visitors to the website to the best possible extent.

a) YouTube

This website uses YouTube videos in the data privacy-friendly two-click variant, i.e. personal data is processed only when you enable the plug-in by clicking on it. YouTube plug-ins are plug-ins provided by YouTube LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. YouTube LLC is a subsidiary of Google Inc., 1600 Amphitheatre Pkwy, Mountain View, CA 94043-1351, USA.

When you enable the plug-ins, information is transmitted to YouTube LLC and may be transmitted to Google Inc. in the USA. This enables YouTube and Google to see that you have visited our website. If you are logged in to your YouTube and/or Google account when you enable the plug-ins, YouTube and/or Google may be able to identify you directly.

Please note that, as the operator of this website, we have no information about the data transmitted to YouTube and Google, the purposes of data collection or the use of this data by Facebook. You can find more information on the data collected in Google’s data privacy policy, which can be accessed at https://policies.google.com/privacy?hl=de.

We cannot provide any information on the storage period, as this falls solely within the area of influence and responsibility of YouTube or Google respectively.

b) Google Maps

This website has integrated a map from Google Maps in order to show you our locations. If you access our website with the Google Maps map, this establishes a connection to Google’s servers and may transmit personal data to Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. If you are logged in to your Google account, Google may be able to identify you directly. If you wish to avoid this, log out of your Google account.
Google’s data privacy policy can be found here: https://policies.google.com/privacy?hl=de.
 

12. Job applications

If you submit a job application to us via our careers page or by e-mail, your personal data will be processed for the purposes of handling your application. The legal basis is section 26 BDSG (data processing for employment-related purposes) and Art. 6 (1) sentence 1 (f) GDPR (legitimate interest). In the case of rejection, your data will be erased six months after your application is rejected. We have a legitimate interest in retaining your data for a period of six months even after rejecting your application in order to defend ourselves against claims under the German General Equal Treatment Act (AGG).

We also take appropriate technical and organisational security measures to protect your data against accidental or intentional manipulation, partial or total loss, destruction or against unauthorised access by third parties. These security measures are continuously improved in line with the state of the art.

General questions about sirens

How does an electronic siren work

 

How does an electronic siren work

How does an electronic siren work? We explain it in this short video

What are the five most distinguishing features of electronic sirens?

  • Operation with rechargeable batteries, therefore independent of mains voltage
  • Large ranges can be achieved
  • Voice announcements are possible
  • No moving parts, therefore very low-maintenance
  • Very good level of efficiency (electrical output/acoustic volume)

What sound propagation options do electronic sirens offer?

  • Omni-directional (360°) sound propagation for standard assembly of the horns
  • Directed mounting of the horns means the sound will carry in this direction.

What is the sound pressure level?

The sound pressure level (SPL) is a logarithmic figure stated in decibels [dB] to describe the intensity of the sound. As the SPL is a technical figure, correlations to the perceived volume is only possible in part. To quantify the perceived volume, assessed sound pressure levels (A,B and C) are used. The A-assessment - dB(A), which is the most similar to the frequency response of the human ear, is therefore generally used for stating the SPL.
When the sound pressure level is raised by 10 dB, this is subjectively perceived as a doubling of the volume.

What signals can be generated with an electronic siren?

The alarm signals of the electronic sirens are generated by an electronic signal generator. These signals are transmitted via a pressure chamber loudspeaker in the siren horns. Theoretically it is possible to generate almost any signal tone and to transmit this via the sirens. The selection of the correct warning signal however is a decisive factor in a siren warning system.

How effective are voice announcements with electronic sirens?

One of the decisive advantages of the electronic sirens is the option that allows voice announcements to be made. As voice messages, stored or live, have a wider frequency range than siren signals, these can only be transmitted at a low volume. The audible range of a voice message is therefore usually lower than a siren signal.

What communication medium is used for a siren system?

With the spread of digital radio networks such as TETRA and DMR, these standards are increasingly replacing the classic analogue data radio.

In addition to a dedicated radio connection, control via a dedicated line is another widespread method. Furthermore, communication channels such as LAN, mobile radio or satellite are possible. Of course, the individual media can also be combined to increase the reliability of a system or to safely reach sirens in poorly connected areas.

 

Are sirens needed at all nowadays?

Natural disasters are becoming more frequent and political uncertainty is also increasing worldwide. It has been shown in the past that sirens can reliably warn people of impending danger. Even in times when almost everyone uses the Internet and has a cell phone, there is no certainty of being reachable at all times and in all places. The alarm of an electronic siren is unambiguous. Digital electronic sirens, with their alarm function, are therefore the first means in the warning chain. 

Countries whose coasts are threatened by tsunamis, earthquakes or flooding, for example, have often relied on sirens for years. As a result of the changed danger situation, the importance of the siren is also increasing significantly again in Germany. Siren networks are once again being modernized, expanded and rebuilt. The importance of the electronic outdoor siren issue is also reflected in the federal government's funding program, which has earmarked 80 million euros for the expansion of Germany's siren network. This sum is often supplemented by additional funding pots from the federal states. 

 

Are electronic sirens quieter than the old electro-mechanical sirens?

Especially when an old electro-mechanical siren is replaced on site with an electronic siren, it is not uncommon for some people to think that the new system is quieter than before. But this is not the case. Electronic sirens such as the ECN or ECI models are even louder than an E57, for example. The only difference is the sound characteristic.

Comparison of the sound characteristics of electro-mechanical sirens and electronic sirens

With an electro-mechanical siren, the sound first catches in the siren canopy, i.e. under the curved bonnet, and then spreads directly downwards (vertically) towards the ground. This has the effect that the siren is perceived as very loud in the immediate area, e.g. at the fire station on whose roof it is installed.

With the electronic siren, on the other hand, the horns are designed and arranged as sound emitters in such a way that the sound spreads primarily horizontally and only falls exponentially towards the ground from a radius of approx. 30 m. This means that people who are in the immediate vicinity of the siren will perceive it as very loud. People who are in the immediate vicinity of the siren therefore initially perceive the sound as not being as loud compared to the conventional motor siren.

The difference is therefore that the electronic siren achieves a higher sound range. This means that fewer sirens are needed to cover a given area. The positive side effect is also that people who are directly below an electronic siren are no longer exposed to a potential risk of hearing damage.

The following figures can be used to substantiate this:

 Maximum sound pressure level at 1 m distance:

E 57  130.50 dB(A)/1 m
ECI 600-DT  138.50 dB(A)/1 m
ECI 1200-DT  144.50 dB(A)/1 m

Average sound pressure level at 30 m distance from siren (in built-up area)

E 57  101 dB(A)/1 m
ECI 600-DT  109 dB(A)/30 m
ECI 1200-DT  115 dB(A)/30 m

Average sound range (in built-up area)

E 57  approx. 450 m
ECI 600-DT  approx. 550 m
ECI 1200-DT  approx. 650 m

Here, 65-70 dB(A) is generally assumed to be the limit at which the average human ear can just perceive the siren signal, provided it is not drowned out by direct ambient noise, e.g. a passing truck.

Conclusion:

Especially when an old electro-mechanical siren is replaced on the spot with an electronic siren, it is not uncommon for some people to feel that the new system is now quieter than before.

Of course, it is also the sound of the electronic siren that differs from that of an electro-mechanical siren. The reason for this is that the wailing sound of an E57 is produced mechanically and that of an electronic siren is digitally modelled on it. However, the points listed clearly show that one must not be misled here.

Technical information about sirens

What is the acoustic output of the electronic siren?

The ECN electronic sirens are available in various output classes. They have a characteristic sound output of 109 dB(A), 115 dB(A), 118 dB(A), 121 dB(A), 123 dB(A) in 30 metres distance. When the sound output is higher, this usually means that greater ranges can be achieved taking the surrounding conditions and environmental influences into account.

What audible ranges can be achieved with a siren?

The audible range of a siren depends on many influencing factors and cannot be calculated generally. A siren with a higher sound output always achieves a greater range than a type with less output power.
Decisive for the range is the height and type of the assembly site and the geography of the surroundings. 

How is omni-directional sound propagation possible with an electronic siren?

The ideal arrangement of the siren horns is when they stand at 180° to each other. The diffraction at the gap of the siren horns ensures omni-directional 360° sound propagation. This physical mechanism ensures that the sound also enters the acoustic shadow. From a physical point of view, the diffraction of the sound waves can be explained using the Van Huygen principle.
The horns of the ECN sirens were developed in consideration of physical laws and were subjected to extensive testing so that an optimum sound propagation is guaranteed.

What power supply is required for an electronic siren?

Our electronic sirens are supplied as standard with a power supply of 230V/50Hz. Optionally, there are solutions for 110V/60Hz available.

How much electricity does an electronic siren consume?

When triggering a siren alarm, the required power needed to operate the amplifier is supplied by the batteries. The batteries are charged via the mains supply 230V (or 110V). The output consumption of an ECN siren is approx. 10 watt in standby mode, whilst the re-charging process of the batteries requires 150 Watt from the mains supply.

The economical solution: We are replacing mechanical sirens with modern technology 

Mechanical sirens, respectively motor-driven sirens have been reliably fulfilled their purpose for many years in the areas of civil defense and to alert fire brigades. However, this type of siren is technologically outdated and prone to faults. The most serious disadvantage compared to modern electronic sirens is that an electromechanical siren (motor-driven siren) cannot be used to sound an alert in the event of a power failure as it can only be operated directly with three-phase current. Replacement increases the reliability and is the most economical solution in terms of running costs.

We at HÖRMANN Warnsysteme are pioneers in the development and manufacturing of sirens in both technical fields.
