This must reflect the distinction between industrial applications and applications in public buildings, which each have their own requirements.
Furthermore, increasing numbers of people worldwide suffer from hearing defects and for them a purely audible alerting system is not effective.
Accessible building regulations are set out in DIN As before, DIN VDE stipulates unequivocally that the operator of a system is responsible for the fire alert and alarm concept. The components are largely harmonized in the EN 54 series of European standards.
In dib emergency such as a fire, it must be guaranteed that every person present in the affected area — even those with impaired ability to hear or see — are immediately and unambiguously alerted and evacuated as quickly as possible.
The focus is always on the actual coverage volume of the signaling device, which can rin used to determine the device requirements. For example, it specifies that throughout the coverage area a minimum light intensity of 0.
Mandatory requirements for visual signaling devices Fire alarm systems are stipulated in building legislation and their use is regulated under the special provisions for construction. A clear light can be permitted in some circumstances, with the fin system concept determined jointly by the operator and the authorities responsible.
Intelligent bus systems are preferred for public buildings.
Depending on the product and the application, the choice of signaling color a clear or a red cover can have an effect on don coverage volume and therefore on the number of signaling devices required. This is stated 1: This is because almost every machine will have a red signaling device and this can lead to confusion and failure to identify a possible fire alarm clearly.
The following article explains the fde of this development for suppliers, installers and designers of fire alarm systems.
Many industrial activities require that ear protectors or goggles are worn and this restricts hearing and view. The primary aim of fire alarm systems is to protect people and property. Industrial buildings normally have high ceilings and large surface areas which clearly define the coverage volume.
It describes clearly how many and in what way visual signaling devices should be planned for inclusion in a project and for the first time states clear requirements concerning their planning and arrangement.
Fire protection in accordance with VDE Actual coverage volumes defined for the first time In ENdih devices are placed in three possible approval categories. There can be good reasons to use a clear light, particularly in industrial settings.
In ENcde devices are placed in three possible approval categories.
Fire protection in accordance with VDE – Pfannenberg
Downtime due to upgrades and modernizations in the relevant areas were reduced to a minimum. The choice of light technology can also be crucial. Conventional systems are preferred for industrial situations as they offer more flexibility in terms of critical power consumption and despite requiring more cabling are a more economical solution.
The preferred color for alarms is red. The product standard also requires the devices to deliver a specific light output and light distribution.
Fire alarm systems in both cases fulfill their purpose of allowing fire to be detected gde an early stage, irrespective of whether people are present or not, so that appropriate action can be taken without delay.
Knowing the actual coverage volume of the signaling devices provides as much certainty as possible throughout the whole project phase and guarantees that the alarm system will be compliant with the standards, thus achieving the objectives and preventing costs from rising excessively. Integration in the FDNet intelligent bus system from Siemens is particularly easy because parameterization can be carried out with the software that puts the system into operation.
On the other hand, Category 033-1 open installation allows the manufacturer to describe the coverage volume in any way or to design the best possible coverage volume for specific applications and constructions.
As such, he or she must determine with the authorities responsible, the designer and possibly the installer of the fire alarm system FAS measures such as how to create an audible and if relevant visual alarm system to meet the requirements of certain areas.
