The smallest fire extinguisher in the world

Fire protection in media technology? Fires regularly break out in electronics.
Before a major electrical fire starts, the world's smallest fire extinguisher
automatically extinguishes the source of danger, directly inside the media technology.
Through this the E-Bulb makes safe devices even safer.

Statistically, a fire breaks out in Germany every 6 minutes due to electricity. Many fires start in electrical devices, including media technology. For example, in January 2021 a fire broke out in the world-famous motorcycle museum in the Tyrolean Ötztal, which started inside a presentation monitor. In the end, the whole museum burnt down and only a few of the valuable exhibits could be saved. This damage could have been prevented with device-integrated fire protection.

To avoid expensive damage or business interruption in the event of a fire, it makes sense to detect the fire as early as possible, extinguishing it directly at its origin while the fire is still small. It is precisely there, at the origin of the fire, where device-integrated fire protection comes into play. The fire protection concepts used in the past are good, but they usually only extinguish the fire when it has spread beyond the media technology.

With device-integrated fire protection, safe electronics can be made even safer.

What fire protection requirements are placed on media technology?

What fire protection requirements are placed on media technology?

In public buildings, such as theaters, schools, hotels, administration buildings, trade fair and exhibition halls, and other sensitive areas, such as hospitals, airports and shopping centers, i.e. areas open to the public, wide-ranging fire protection regulations apply. The fire protection requirements for installing media technology in these sensitive areas are often extensive. In order to be able to install digital signage, information points, or LED walls, for example, additional fire protection requirements must usually be met.

With device-integrated fire protection and the E-Bulb, media technology for these areas can be upgraded easily and cost-effectively. As a result, it is often possible to implement media installations in previously unthinkable areas, even in escape and rescue routes.

What is the E-Bulb?

The E-Bulb is also known as the smallest fire extinguisher in the world. The smallest version of the E-Bulb is just two centimeters tall and fits into almost any media technology.

The E-Bulb can be installed directly inside media technology by manufacturers and certified system integrators, thus protecting the technology from within. Should there be a technical defect in the media technology, causing a fire to start, the E-Bulb can detect the fire, extinguish it, and prevent reignition before the fire emerges from the device potentially causing major damage.

The E-Bulb is a CIFEA (UL 60692) and a UL recognized component

What is the AMFE?

The AMFE is a self-sufficient, power-independent automatic miniature fire extinguishing unit. The AMFE supplements the smallest fire extinguisher, the E-Bulb, for volumes too large for the E-Bulb to protect alone. With its 6 different sizes and fully selectable activation temperatures from 68 ° C to 141 ° C, the AMFE offers permanent and retrofittable security against the inherent fire risk, with free volumes of up to 1.5m³. This makes the small AMFE ideal for use in somewhat larger media technology devices and systems.

Where can AMFE be used

This makes the small AMFE ideal for use in somewhat larger media technology devices and systems. The AMFE range can be installed directly into media technology by manufacturers and certified system integrators, thus protecting the technology from the inside. If there should be a fire-inducing defect in the media technology, the AMFE detects it, fights the fire directly at the origin, long before an external effect occurs, and it can even report its activation to the operator via a signal circuit. The simple installation also enables existing systems to be retrofitted. By actively interconnecting several AMFEs (R-AMFE), volumes slightly larger than 1.5m³ can also be protected (ask us!).

How can the investment be earned back?

The E-Bulb is an innovation that protects and saves costs.

Protection against
business interruptions

Every second counts in a fire. The earlier the fire is discovered and extinguished, the less damage occurs. Those using E-Bulbs can completely protect themselves from business interruptions, or at least shorten the interruption time. Every third fire in industry causes property damage of over €500,000, often as a result of the incident the affected companies do not recover. Only 23 percent of the firms affected by the fires can fully resume business operations. However, more than 40 percent of the companies have to completely shut down their operations after a fire (Source: “Logistics Today”). The safety gain through the use of integrated fire protection represents a very good cost-benefit ratio.

Building approval also in an escape route

In sensitive areas such as shopping centers, trade fairs, airports or train stations, electrical appliances often change from being the “cause of fire” to being “involved in the fire”. By installing and using device-integrated fire protection, such as E-Bulbs, electrical devices such as digital signage and LED advertising screens become safer. This means that printers, televisions or billboards can be given installation approval even in escape route areas.

Gain competitive

As a manufacturer or operator, you can get ahead of your competitors with the E-Bulb because:

  • Safety as a product characteristic is valued by customers and leads to higher customer satisfaction
  • A device-integrated fire-stop can be a unique selling point in your industry, securing important market share for you
  • Preventive fire protection can help to win new orders
  • The E-Bulb can help market the added value of an integrated fire-stop to customers

Where is device-integrated fire protection already state of the art?

Preventive Fire Protection:
Projects & Case Studies

Through the professional cooperation between operators, manufacturers / system integrators, fire protection experts,
test institutes, and the JOB Design-in team, many projects have already been successfully delivered. Here is a selection of some interesting projects:

Frankfurt Airport (FRA)

Case Study Flughafen Frankfurt

Frankfurt am Main Airport is the largest airport in Germany and the 15th largest airport worldwide (in terms of passenger volume). The security requirements for every type of technical infrastructure there are correspondingly high. In order to obtain approval for the installation of media technology in this sensitive environment, along with others SAMSUNG technology was equipped with E-Bulbs to enable a large LED wall in Terminal 1 (A). From the point of view of the fire protection experts, this made it possible to change the media technology from being the potential “cause of the fire” to being “involved in the fire”.

Berlin Airport (BER)

The new international airport in Berlin faced the challenge of gaining approval to use modern digital media technology in public and semi-public areas, without having to significantly change the existing fire protection concept. Modern electronic information points fitted with a self-extinguishing device were required. Automatic miniature fire extinguishing units AMFE from JOB were used. Thanks to the proven fire detection by Thermo Bulbs, which are also used in billions of sprinklers around the world, any fire that may arise within the display electronics can be detected as early as possible and effectively extinguished directly at its origin. By using the S-AMFE, which makes activation detectable, the affected device is disconnected from the power supply at the same time, so that no re-ignition can take place. The integration of AMFE to minimize risk ensures maximum safety for passengers and visitors to BER Airport.

Vehicle Showcase (FRA)

Flughafen Frankfurt Showcase

Due to the special spatial requirements, R-AMFE were used here connected to a control box, which activates all AMFEs at the same time through external smoke switches, to ensure the necessary design concentration of the extinguishing agent at every point within the platform. In addition, the R-AMFE always activates through thermal triggering, almost redundantly. The system integrator, BenHur GmbH, has successfully used this solution on many other devices in critical application areas (public spaces). By integrating the AMFE to minimize risk, this interesting installation in the security area of the airport was approved, as this guarantees maximum safety for passengers and visitors to the airport.

How does a “cause of the fire” become just “involved in the fire”?

From the point of view of insurers and fire protection experts, electrical devices such as media technology are “causes of fire”. If you manage to protect against the inherent fire risk of media technology, there is a possibility that media technology will be classified as a party “involved in the fire” and installation approval can be granted. The following steps demonstrate how this can work:

Step 1:


The first step is to check the fire protection requirements for media technology on the part of the future operator, the insurance company, and the applicable building regulations.

Step 2:


As soon as the requirements have been clarified, the JOB Design-in team can work with the manufacturer, or system integrator, to adapt the design with regard to integrated fire protection. An initial theoretical analysis of the facts is usually followed by fire and extinguishing simulations, and finally extinguishing tests.

Step 3:

Verification of
protective effect

In addition to considering the fire risk from the inside (including electronics), the fire risk from the outside must also be assessed. Independent institutes and material testing institutes provide support with the verification, e.g. in relation to the material testing standard DIN EN13501-1 and the classification according to A, S, D (including droplet formation).

Step 4:


After extensive testing, the overall concept is submitted to the future operator, the engineering office, and / or the approval authority for approval. Thanks to this stringent procedure, many successful projects with device-integrated fire protection have already been implemented cost-effectively.

Fire protection in sensitive areas,
which fire risks are considered?

Basically, two scenarios are assessed in a risk assessment. On the one hand the fire risk from the outside, and on the other hand the fire riskfrom the inside, e.g. due to a technical defect. Media technology must be designed in such a way that both scenarios pose no danger.

External fire risk

In the field of media technology, DIN EN 13501-1 has prevailed. The European classification for the fire behavior of building materials describes additional parameters such as smoke development and burning waste / dripping. The materials must not generate burning droplets and should have low smoke emissions. In addition, smoke development (smoke: classes s1, s2 and s3) and burning droplets (droplets: classes d0, d1, d2) are classified:

s1: low smoke development s2: medium smoke development
s3: high smoke development
d0: no flaming droplets / falling off within 600 seconds
d1: no flaming droplets / falling off with an afterburn time longer than 10 seconds within 600 seconds
d2: no performance determined

As a manufacturer of fire protection components, we cannot tell you whether your media technology meets these requirements; it is advisable to have the media technology checked by an independent certification body. However, we can support you in minimizing the inherent fire risk.

Internal fire risk

With integrated fire protection and E-Bulb & AMFE, the inherent fire risk can be minimized. Experience has shown that the manufacturer or system integrator comes to us to implement the integration of the mini fire extinguisher into a specific product (LED module, digital signage, interactive info point, etc.) In cooperation with the JOB Design-in team, a fire protection concept is created after completion of a technical assessment, simulations and extinguishing tests. This fire protection concept is then checked and approved by the engineering office, or the future operator.
