DEHN protects Safety Systems

Ensure reliable operation of your safety systems

No compromises on safety Be it fire protection, burglary protection or emergency and escape route lighting: Electrical safety systems are only safe if they do not fail during thunderstorms which are most common in the summer months. If lightning strikes and surges destroy safety systems and safety-related functions are thus no longer available, human life is at risk. Surges may lead to false alarms and high follow-up costs. Therefore it is vital to integrate safety systems in a lightning and surge protection concept. To this end, manufacturers, consultants and installers must comply with...

Lightning protection zones in buildings equipped with safety systems Building management, telecommunication, control and safety systems are increasingly used in all areas of residential and functional buildings. These networked systems make the building intelligent and ensure its optimised use. Building owners and operators make high demands on the availability and reliability of these systems. An external lightning protection system protects persons and material assets in a building from fire, however, electrical and electronic systems are not protected against failure as a result of...

Depending on the system requirements, data must not only be reliably and correctly transmitted, but also available around the clock. It is therefore important to protect safety systems against the effects of a lightning strike. BLITZDUCTOR® XT combined arrester The...

Manufacturer-specific solutions Since the interfaces of hazard alarm systems to be protected differ from manufacturer to manufacturer, surge protective devices frequently have a different design or different nominal data. In cooperation with renowned manufacturers, we offer surge protective devices for all common interfaces in safety systems. The DIN rail mounted and energy-coordinated combined arrester protects unearthed d.c. supply systems. DEHNpatch The universal arrester for information technology is ideally suited for cabling systems according to class E up to 250 MHz. It protects all...

Power supply The a.c. voltage supply of fire and burglar alarm systems places especially high demands on surge protective devices. DEHNguard® and DEHNrail which have a high discharge capacity due to their zinc oxide varistors meet these demands and ensure safe system operation. The fact that our surge protective devices are VdS-certified contributes to the high quality of our products. DEHNguard® The modular two-pole type 2 surge arrester for single-phase TN systems consists of a base part and plug-in protection module with floating changeover contact.1 DEHNrail The two-pole type 3 surge...

Safety lighting systems Due to their application and normative requirements, safety lighting systems require maximum system availability. The d.c. and a.c. voltage supply of these systems places especially high demands on surge protective devices. DEHNsecure meets these demands for both supply systems thanks to its special spark gap technology. The modular and coordinated singlepole lightning current arrester for d.c. applications is available with or without remote signalling contact for the monitoring device.

CCTV systems Our economically and technically sound lightning and surge protection concepts allow reliable planning and installation of your safety systems. BLITZDUCTOR® XT and DEHNguard® arresters are ideal for use in CCTV systems. The combined arrester is a pluggable and universal multipole lightning current and surge arrester for safety systems. It is ideally suited for installations and systems that require maximum availability. The two-part arrester consists of a DIN rail mounted base part and protection module and features an integrated LifeCheck® function for fast and easy arrester...

DEHN protects Our key objective is to protect workers and material assets. It was our pioneering spirit and innovative ideas that have defined our company for more than 100 years and made us a market leader with more than 1,400 employees. Our products and developments reflect our market feasibility, commitment and ideas. As early as in 1923 our founder Hans Dehn started production of external lightning protection and earthing components to optimise the protection of buildings and installations. In 1954, we launched the first series of surge protective devices. Constant further development...
