Reliable alarm in case of danger

Fire alarm and voice alarm systems

Fire alarm and voice alarm systems in public buildings with high public traffic are often subject to building regulations.

Fire alarm and voice alarm systems are different systems that are used in a building for security. They can be interconnected to work together in the event of a fire or other emergency situation.

A fire alarm system specializes in detecting smoke, heat or other signs of fire. As soon as the fire alarm system triggers an alarm, a message is usually sent to the fire department or other relevant authorities.

Voice alarm systems (VAS) are becoming increasingly important, as they can also guide people who are unfamiliar with the area - e.g. in shopping malls and department stores - to safety by making targeted announcements after a fire has been detected. In all affected areas, SAA enable various automatic messages as well as situation-dependent live announcements by security officers or the fire department.

This means that voice alarm systems that are controlled by a fire alarm system belong to the alarm systems of hazard detection technology. They are therefore part of the technical systems and equipment in accordance with building regulations.

Here too, VdS supports operators quickly and reliably in fulfilling all requirements. In addition to the required tests on the voice alarm control panel, our engineers also measure speech intelligibility and relevant acoustic parameters in the alarm areas. This means that it can be proven at any time that the SAA reaches everyone in the building.
