MED option. EAC conformity. Electrical data. Ordering details. PA X Alternating tone UK BS fire alarm, increased urgency - railway crossing. In this example, the dB A sounder performance is immediately apparent and allows to define how much devices are required based on the area to cover.
The lens cover is large, highly visible, and available in a variety of colors. The xenon strobe flash tube contains no filament to break and is secured by a steel clamp to further protect it from abuse. These figures shown are mainly for a quick orientation.

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. Pfannenberg shows what Signaling Devices can Achieve. 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. 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. 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.
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. Contact us for more information! The perception of acoustic signaling devices is determined by many factors. In particular, ambient noise and the use of hearing protection must be taken into account.
Whether or not the audible signal from a sounder is successfully perceived is not just dependent on the output sound level generated and technology used to create the alarm signal.
Ambient noise levels and sounder placement location are crucial elements that should not be overlooked. The adjacent example illustrates the effect on coverage volume of an dB A audible signaling device due to a 10 dB A change in ambient noise level. Increasing from 75 dB A to 85 dB A shows that the warning signal will not be successfully perceived. The 3D-Coverage values show that the effective covered area is significantly reduced when the ambient noise level rises.
If the alarm system designer does not take all aspects into consideration, the consequences can spell danger for people in the surrounding area. Every aspect of the alarm system design process is susceptible to errors. Incomplete system requirements, inattention to environmental factors, insufficient product specifications, and lack of actual signal coverage dimensions can all contribute to an inadequate safety mechanism.
The 3D-Coverage approach planners users avoid errors and achieve the optimum solution. Various standards and codes are in force which influences the planning of signaling solutions.
However, many of them are merely superficial. For example, the EU Machine Directive stipulates that machinery manufacturers must put in place suitable measures to minimize the risks of operating the machinery — but if signaling is a potential solution, there are no defined requirements for the performance of such devices.
Since the machinery builder is responsible for mitigating operational risks, it is imperative to utilize signaling devices which offer sufficient effective coverage to operators and nearby personnel. Use with existing water or one of our Chillers.
