Surge Protection for Office and Administration Buildings

For administration, data processing has become indispensable. PCs, servers and networks have become part of the minimum equipment. A breakdown is unacceptable. Workflow has been adapted too much to these systems. Also important are telephone systems and fax machines. Moreover, there are building automation systems interconnected by bus systems like EIB/KNX and LON.

Even in case of a thunderstorm - everything has to work properly.

Protecting communications

Protection for power supply systems

The drawing on the right shows an example of an office building. For power supply, combined lightning current and surge arresters, e.g. DEHNventil^® modular can be used as well as surge arresters of Type DEHNguard^® modular . For protecting the terminal equipment, e.g. DEHNrail modular , SFL-Protector or DEHNsafe can be used. This reduces inducted voltages and switching overvoltages safely.

Protection for communication

Both data and voice transmission require corresponding protective components for safe operation. Networks are generally constructed as universal wiring in accordance with EN 50173. Even if glass fibre lines between buildings and floor distribution boards are standard today, copper lines are normally installed from the floor distribution board to the terminal equipment. Therefore, protection for HUBs, bridges, or switches by NET-Protector LSA 4 TP is required. Terminal equipment can be protected by the patch cable or DEHNpatch .

For IT lines between buildings the DPG enclosure for equipotentional bonding can be used. It can be supplied with LSA disconnection blocks and DEHNrapid^®LSA plug-in terminal blocks with lightning current carrying capability. For protecting the TC system, NET-Protector TC 2 LSA is used for the outgoing lines to the system telephones - the system telephone can be connected to e.g. DSM TC 1 SK protection module.

Building automation protected from surges

A breakdown of the building automation can have severe consequences. For example, if the air conditioning system breaks down due to surges, the data processing centre or a server might have to be disconnected or shut down. This can be prevented. As can also be taken from the drawing, bus systems such as EIB/KNX or LON can be protected by components like BUStector , DEHNconnect , or BLITZDUCTOR^®XT .

Installing SPDs in accordance with the concept and in a consequent way helps to considerably increase availability.
