Project Management – Introducing our Order Processing Department

In the latest blog post my colleague Janina gave you a better understanding of how the INDUSTRONIC Sales Department operates. With this week’s article we will take a closer look at the next steps along the order process.

As soon as an order is placed with INDUSTRONIC and contract review is finished the Sales Department hands over the project to our Project Management team. First, it is assigned to one of the project managers in the department. This person is the main contact relating to the project and coordinates all the tasks that are nessesary for a successfull delivery. The responsibility goes even further and includes payment monitoring and customer support during the warranty period.

Before an order confirmation is sent to the customer, possible issues regarding the delivery conditions and terms of payment have to be clarified. Most of the time, this involves tasks such as answering emails and taking care of any formalities. For technical questions the Project Engineering Department or in some cases even the product developers have to be consulted. To make sure that all components for a respective project are delivered in time, the coordination with the Purchasing Department is also important. Finally, after a production date is defined, the order confirmation can be sent.

Project Management

The project manager and colleagues from other departments are working closely together.

In addition to that, the Project Management team is responsible for the organisation and supervision of factory acceptance tests with customers and partners. Depending on the size of the project, the number of participants and the duration can vary from one person that stays for just one day to a big group that is on site for the whole week.

When the delivery date is fixed, the project manager has to organize the packaging and shipping. Especially for goods that are shipped by vessel the requirements, such as seaworthy packaging, are very high. And of course, the whole customs clearance process has to be coordinated when it comes to international deliveries.

Aside from these complex projects, the Order Processing Department handles spare part deliveries as well as repair orders and is also responsible for the coordination of service orders.

As you can see, the tasks our Project Management team has to deal with every day are very wide-ranging.

Get to know the NPA – Modular Design & Flexible Installation

The IP-based PA unit of the NPA series is used for intelligent public address solutions. It seamlessly interfaces with the INTRON-D plus communication and public address system via Ethernet/IP.

Its modular design offers individual combinations of slide-in amplifier modules and power supply units. They can be simply inserted and replaced on the back of the device. You can also install a redundant power supply unit and amplifier module to ensure uninterrupted operation. There is also the option to provide an additional NPA device as backup component (N+1 component redundancy) to comply with increased safety requirements.


Redundancy concept


Slide-in modules & units









You can start small with the basic coniguration offering 1 digital amplifier channel, up to 4 monitored speaker circuits and an output power of 300 Watts. If you require more amplifier power, you can easily expand your device at any time.

The NPA’s maximum configuration comes with 4 digital amplifier channels which can be used simultaneously, up to 8 monitored speaker circuits and a maximum output power of 600 Watts. Use several IP PA units to implement even more extensive solutions.

The NPA can be installed both as centralized or decentralized solution. If you decide in favor of a centralized installation, the NPA is usually mounted into a central exchange cabinet. For a decentralized installation, the device is installed indoors at different places throughout the plant and near the speakers. The short cable distances reduce cabling costs. In general, the NPA can be installed anywhere on the LAN treated as independent IP amplifier with integrated zone selection and optional speaker monitoring.


Decentralized installation of the NPA

Successful Training at the INDUSTRONIC Representative Office in Singapore

In order to further its prominent position in the South-East Asian region and to cultivate important partnerships two trainers from the Headquarters in Wertheim recently visited the INDUSTRONIC Representative Office in Singapore. Their mission was to hold a hands-on training and support efforts for networking of the partners.



Bobby Tay, the host of the event, invited local INDUSTRONIC partners to the Representative Office in Singapore. Altogether there were eleven participants including two experienced trainers from Germany. The goal was to unite partners from Korea, Malaysia and Vietnam and to provide new business opportunities, and offer superior quality training. These types of networking events allow for a valuable exchange and strategic cooperation.

The hands-on training was held with two demo systems configured as one system network. This was to demonstrate the features of INDUSTRONIC’s state of the art IP devices (e.g. IP-based PA unit (NPA), IP Outdoor Intercom Station (NRO), IP Desktop Intercom Station (Access Panel)). Furthermore, configuration, navigation and programming with the most current Config Manager software was on the agenda.

The training lasted for five days and was concluded with a relaxing dinner on the last evening. Altogether, the training session in South-East Asia was an overwhelming success for all participants!

PA Design – Sound studies – When your voice is understood Part 2 – The sound study

The sound study

As you might remember in our first post about ‘PA Design – Sound Studies’ we mentioned the needed data for the first step. For a real sound study we need further data in addition to the existing information.


Noise map
Basis of all calculations is the so-called noise map. The noise map can be generated in two ways; either to measure it with calibrated noise level meters or to compute it with a noise mapping / noise prediction software program.

The noise measurement can only be established on industrial plants if all machines and installations are in operation. The software calculation can only be executed if the data of all machines, buildings, structures, etc. is available. The calculation of noise maps can also be carried out by the customer or another 3rd party company.

A typical noise map looks like this one:


We can see different kind of noise sources (surface, point and/or line source).
Housings, buildings and other structures are also visible.
Different colors mean different noise levels.

The noise map – Import or rebuild

The most labor-saving method is if the noise prediction software has an export filter for our calculation software. In this case we can quickly import the noise map and continue with the proper work.

If there is no export noise map data for the calculation software available we must rebuild the noise map according to the supplied printed paper work and documents as precisely as possible. This work is very time consuming and not easy to handle.


Where are the speakers?

After generating the noise map we can now begin with placing the speakers depending on hazardous or non-hazardous areas.

There are several rules to be observed, here are examples for the most important ones:
a) The speakers should only cover the manned areas where workers could be present.

b) We must be aware of too high sound pressure levels, e.g. above 120 dB, due to potential hearing damages.

c) At an ambient noise above 85 dB additional flashing beacons should be installed.

d) Speakers should be mounted ≥ 3 meters above ground.

e) Hazardous areas with appropriate Ex-proof speakers.
…but there are some more…


Signal to noise

After placing and aligning the speakers, we calculate the sound map and at least the signal to noise map (SNR).

The sound map represents the radiated sound of the speakers at the listening plane without noise, whereas the signal to noise ratio constitutes the result of a mathematical calculation:

(dB_Signal_Map) – (dB_Noise_Map)

The signal to noise ratio should be ≥ 10 dB and should not exceed 20-25 dB. This may differ from standard to standard, country to country, and customer to customer.

From our experience with the above mentioned ratio (SNR) – beside other factors – a good intelligibility should be met.


This picture shows above area with placed (3 meters above ground) and aligned (-30° off horizontal axis) speakers, supported by 2 flashing beacons – the signal to noise ratio shows good coverage at nearly any point.


At the end

As you can see, a lot of data and work is needed to create a sound study. But when the project team works hand in hand, a well defined PAGA system with good intelligibility is the result.

Alarms Can Save Lives

It is important for the staff of an industrial plant to pay close attention to alarms broadcasted via speakers or sirens in order to respond appropriately in case of an emergency (e.g. fire, gas alarm). Alarms usually consist of three pillars: acoustic signals, voice announcements, and visual signals.

Acoustic signals notify people of an emergency without giving additional information. This can be a short tone sequence which is played back prior to a voice announcement. The effect is that listeners focus on the announcement and suspend conversations or current activities.

In several industries (e.g. chemical plants), there are tone sequences for particular emergency situations specified by the plant operator due to standards or local legislation. When these acoustic signals (e.g. evacuation tone or fire alarm tone) are played back, emergency-trained staff immediately recognizes them and knows how to react. Click on the Play button to listen to a fire alarm tone example.

Voice announcements or voice messages can give precise and immediate information tailored to the type of emergency and your environment. They instruct people on how to respond appropriately in an urgent situation. (Example: “Attention! Attention! Fire detected on Floor A! Please keep calm and leave the building immediately. Go directly to the assembly point. Do not use the elevator.”). Listening to a human voice telling you what to do can also have a calming effect on people in emergency situations.

Voice announcements must inform people quickly and must be clear, concise and easy to understand for everyone. Hence, good audibility and sound level are very important.

Visual signals are usually flashing warning beacons which can be used as additional indicators of an alarm, especially in areas with high ambient noise levels.

The three pillars of an alarm

The three pillars of an alarm

Combining all three pillars described above in industrial environments is a good way to cover different local conditions. A pre-announcement tone which sounds familiar to the staff can attract the attention to the voice message which comes afterwards and which contains specific instructions. A flashing warning beacon is also helpful as a visual indicator of an alarm if the staff works in very loud environments.

INDUSTRONIC offers excellent audibility of acoustic tones and voice announcements even in extremely loud environments. Customized texts or tones can be pre-recorded and stored on our digital audio processor (DAP). You can configure them so that they are automatically played back in a particular case of emergency. A CD-ROM with various tone examples can be ordered from INDUSTRONIC. We also provide a wide range of flashing warning beacons with various lens colors and light options, also for use in potentially explosive areas.

PA Design – Sound Studies – Part 1

When your voice is understood

Part 1 – Evaluation / Budget Planning

Do you remember past times?

In the past, say 30 years ago, a PA system was usually designed by experienced engineers and technicians, with more or less – good results.

There was no possibility to predict the dispersion of a speaker structure in an industrial area with their machines and installations and to calculate the effective signal-to-noise ratio due to poor computing power.

Therefore, some rules of thumb were developed to meet common and simple requirements.

And if there was no rule of thumb for your existing project?

…then the simple ‘The More the Better’ motto was applied…

And now?Checklist_PA

We at INDUSTRONIC work in a different manner. The PA design is strictly made and calculated with different software applications and hardware appliances. However for our design work we need more data from our customers than before.


To facilitate your work we prepared some checklists which retrieve the following data:

• Type of speaker/s
• Hazardous areas
• Ambient noise/s
• Plot plans of areas
• Buildings / Side views
• …

When we get this data back, our engineers can then calculate and create a bill of material (BoM) of the equipment required.


Ambient noise?

In some cases, while there is no ambient noise map available, there is a need to measure and map the ambient noise. This can be done by third party companies selected by the customer or by INDUSTRONIC.

For budget planning it should be sufficient to calculate only with a few ‘large surface noise carpets’ to build the noise map and obtain the amount of devices (speakers, flash beacons if noise > 85 dB).

The calculation program works with the simple ‘1/r inverse distance law’. Some parameters like speaker type, general absorption, general ambient noise, signal to noise and power tapping must be inserted additionally.


See the Results!

As a result we get the ‘undisturbed range’ of the speaker with the
parameters entered.

With this range we can calculate the total amount of speakers.

What about indoor areas?

In indoor areas like admin buildings, workplaces and living quarters there should be at least 1 (one) loudspeaker in each room with doors.


On the one hand it is due to regulations or standards, on the other hand it is logical that everybody should be alarmed in case of fire…


That’s all?

Not yet – some documents must be created where all speakers are correctly assigned to the places required.

For more precise sound planning some of our customers need a so-called sound study. But this is another story – learn more in our Part 2 of PA Design / Sound Studies.

Quality Management System Successfully Recertified

DIN ISO 9001_2008 quality management system certificate_engl

Our new DIN ISO 9001:2008 Certificate is valid until April 2018

Once again, INDUSTRONIC has been recertified with the DIN ISO 9001:2008 certificate.

Every 3 years, a recertification audit takes place to renew the certificate for our quality management system. The audit is executed by an independent third party accreditation body (in our case DEKRA). In March, two external auditors visited the company to make sure that all our processes comply with the regulations of the DIN ISO 9001:2008 standard.

During their visit they questioned the managers and employees of several important processes. Beside others, the following teams were checked:

  • Product development
  • Production
  • Purchasing
  • Sales & Project Management
  • Project Engineering
  • Marketing

After thorough examination, our processes were found to be working fine. Further elements of the quality management system are the determination of customer satisfaction and the assessment of the management. We have fulfilled all necessary requirements and therefore, the audit was passed successfully.

The new certificate is now valid until April 2018. In the following two years, one surveillance audit per year is obligatory according to the DEKRA regulations.
