SEVEN is a scalable public address and voice alarm system, suitable for multi-purpose architectures. The SEVEN series systems are compact units containing all necessary components within one enclosure for voice alarm applications in fire-fighting systems, meeting the requirements of EN 54-16 and EN 54-4.

The SEVEN system can be scaled up to 254 devices connected via TCP/IP data network, with fibre optic connection in a ring topology. Allows the system to be scaled up with control units, paging and firefighter microphones. Each device can operate as an independent node, interconnected by the data network. Live announcements and background music can be transmitted via the data network up to a maximum of 45 audio signals. Connection with Cat5 cable and SFP optical fibre.

Each system is equipped with a control unit with six Class D amplifiers distributing 100 V line signal to 16 AB zones with 32 loudspeaker lines. The amplifiers can function as a main or backup amplifier, to ensure operation at all times for emergency priority signals. It has monitoring and signalling of system faults and loudspeaker lines. It also has a firefighter's microphone, touch screen control, DSP, buttons and programmable GPI/O inputs and outputs, programmer, 6 simultaneous messages with expandable memory, etc.

The systems integrate a power supply with backup function in case of power loss, in compliance with EN 54-4 standard. Includes a charger with space for mounting batteries.

The system features all the elements of a voice alarm system in an IP30 protection 15U rack enclosure. SEVEN is designed for easy installation and commissioning.

Due to its distributed architecture, the SEVEN system can cover all types of projects and installations, train stations, airports, hotels, shopping centres, stadiums, industrial installations, etc.
