NSC

Pioneers in voice alarm systems

Clear announcements in complex environments

A voice alarm system (VAS) is essential in places of assembly or buildings with a high number of occupants. In an emergency, the goal is to protect lives from fire and to carry out a structured and highly effective evacuation in a professional manner. A VAS is the means to achieve this goal and is considered the current state of the art. It is important to note that the fire control panel detects the fire and triggers the VAS.

To offer its customers a comprehensive range of safety products, NSC has not limited itself to fire alarm technology but has also expanded its expertise in public address and evacuation systems. Voice alarm systems have developed into one of the most important areas within safety technology. Accordingly, NSC attaches the highest importance to this field. NSC is a trusted partner for security system installers and has established itself as a supplier of top-quality equipment used throughout this sector.

Our voice alarm systems operate in efficient synergy with NSC fire control panels. The modular MILO system and the autonomous compact control panel BOX-500 are capable of transmitting voice messages, alarm signals, advertising content, and music with exceptional clarity and intelligibility. Their high performance enables the delivery of messages and music with excellent sound quality in environments of any size where large numbers of people need to communicate, be informed, and be evacuated in emergencies. In the event of an evacuation, the system ensures the orderly dissemination of alarm messages, facilitating safe, stepwise building evacuation. Besides MILO and BOX-500, our product range also includes the voice alarm systems MultiVes, MidiVes, and MiniVes.

Our VAS systems deliver outstanding performance in every respect and can be used in almost any situation. Contact us to learn more about the individual features or visit the product detail pages.
