Hold-open systems for fire-resisting shutters

Invisible guards

Places where many people meet must provide ultimate safety. This requirement can be met by convincing fire protection concepts to protect human lives and property values. We offer products which are characterized by their versatile functionality and flexibility.

Where reliable and well-thought-out fire protection concepts are concerned, for example in industry, offices or public administration buildings, Hekatron is the right contact, being the market leader in the field of hold-open systems.

If a fire breaks out in the Hamburg Europa Passage, the especially-painted smoke switches and the control of the hold-open systems ensure that the huge fire-resistant doors are closed - by means of motors and with a time delay. As a result, fire and smoke will be restricted to the fire compartment, so that visitors and employees can safely escape from the danger zone. Under normal conditions, the technical components of the fire protection system are invisible for the human eye, or their color and shape are such that their outer appearance blends well with the surroundings of the shopping mall.Hekatron offers the proper smoke switch for a variety of fields of application - from standard and design to radio-operated smoke switches - including the appropriate approval.
