Protecting Man, Machine and the Environment. Even under the harshest conditions


Pfannenberg's PATROL, PYRA and DS series Flashing Lights and Sounders meet the highest standards in terms of impact and vibration-resistance in a range of different protection classes. These devices have passed vibration tests conducted under DNV-GL guidelines. DNV-GL certification assures the operators of our signaling devices that they are of the highest quality and reliability.


Outstanding impact and vibration-resistance
Our DNV-GL-certified signaling devices are impervious to vibration, jarring and impact. Their PCB components are attached very firmly to prevent damage from vibration. Furthermore, they are fitted with metal brackets which absorb or attenuate oscillation and vibration.

Higher resistance to impact and shock
In heavy industry or logistics, for example, signaling devices are exposed to particularly high levels of mechanical stress. For applications in these and other challenging areas, we offer DNV-GL certified signaling devices which also have IK08 protection classification. Even without a protective cage, they resist high levels of mechanical stress and are guaranteed to function reliably at all times.

Dust and water resistant, UV-stable, heat tolerant and frost proofed
Many of our DNV-GL-certified signaling devices are equipped with other features such as aluminum housing and have high protection classifications such as IP 66 or IP 67 which means that they are impervious to strong jets of water and short periods of immersion in water and to aggressive media. All this qualifies them for use in particularly challenging conditions.

Easy and safe planning: Pfannenberg Sizing Software PSS
Our Pfannenberg Sizing Software (PSS) is a cost-free and very user-friendly tool which delivers an immediate and informed recommendation on devices, avoiding expensive over-specification and risky under-specification at the planning stage or in a review of the configuration.

Immediately see device performance for a given space: Pfannenberg 3D Coverage
Our signaling devices are outstandingly efficient. The 3D-Coverage planning method along with the Pfannenberg Sizing Software provides reliable values for the length, width and height of the area guaranteed to be covered by the signal in relation to different environmental conditions.
