Voice alarm EN 54 Compact SEVEN-640NR-2

SEVEN is a scalable voice alarm and public address system, suitable for versatile architectures. The SEVEN series systems are compact units that contain all the necessary components for voice alarm applications in fire alarm systems, meeting the requirements of the EN 54-16 and EN 54-4 standards.

The SEVEN system can be expanded with up to 254 devices connected via TCP/IP data network, with fiber optic connection in ring topology. It allows the system to be expanded with control units, announcement microphones, and firefighter microphones. Each device can function as an independent node, interconnected by the data network. Through the data network, live announcements and background music can be transmitted, supporting up to a maximum of 45 audio signals. Connection via Cat5 cable and SFP fiber optic.

Each system is equipped with a control unit with two Class D amplifiers that distribute 100 V line signal to 8 speaker zones. The two amplifiers can operate simultaneously, limiting the power to 320 W, or one amplifier functions as the main, and the other as redundant, ensuring continuous operation for priority emergency signals. It has supervision and fault signaling for the system and speaker lines. Additionally, it features a firefighter microphone, touch screen control, DSP, buttons, programmable GPI/O inputs and outputs, scheduler, 2 simultaneous messages with expandable memory, and a network card for fiber SFP connection, etc.

The systems integrate a power supply with a backup function in case of power loss, according to the EN 54-4 standard. It includes a charger.

The system includes all elements of a voice alarm system in a rack-mountable 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, such as train stations, airports, hotels, shopping centers, stadiums, industrial facilities, etc.
