Signaling Visualized With Pfannenberg’S 3D Coverage

A Holistic Approach to Alarm Notification Planning

With Pfannenberg’s 3D-Coverage approach, the design of alarm and warning notification systems becomes easier and more reliable. The methodology takes advantage of effective performance in a given space rather than relying solely on nominal output data presented in typical specifications. The goal of 3D-Coverage is to provide a visual representation of the effective range of the signaling device, lending justification to its successful implementation in the defined space. This valuable approach helps planners define alarm systems which guarantee effective safety warnings to personnel.

Actual Information
About the Coverage Area

The information traditionally found in technical data sheets does not allow any conclusions to be drawn about the actual performance of a product in a given space. In an innovative approach, 3D-Coverage provides designers and safety officers with information about the size of the area effectively covered by a signaling device.

Perception
Counts

The major benefit of 3D-Coverage is that it takes factors such as ambient noise level and light intensity into account, focusing on the extent to which signals can be guaranteed to be heard and seen – an essential requirement for safe signaling solutions.

The Differences in
Actual Performance

3D-Coverage reveals the differences in actual performance which previously were not detected until it was too late. A frequent reason for dangerous under-sizing is the assumption that sounders of the same performance class have identical transmission characteristics in a given space. The adjacent diagram shows how very different the effective performance can actually be.

Why Pfannenberg Signaling
Devices are Better

The performance of many sounder designs focuses on their capability in the axial (forward) direction, while inadequate output levels in the radial direction (side and downwards) is often overlooked. With the optimized design of Pfannenberg sounders, the sound propagation is distributed over a wider area in all directions.

Ideal Sizing

By utilizing the 3D-Coverage concept, properly sized signaling devices are specified to ensure safety to personnel under the ambient conditions present – often leading to the most cost-efficient system in terms of number of units and installation expenses.
