The DIA group of supermarkets has a distribution centre of more than 68,000 square meters in Illescas (Toledo), the largest of all its warehouses and the first step in a new efficient and sustainable logistics network, with 100% circular waste management. Some 8,000 low turnover non-perishable food references will be distributed from this centre and it will provide regional service to some 500 stores in the communities of Madrid, Castilla-La Mancha and Castilla y León. The public address and voice alarm system has been made with the COMPACT, system, certified EN 54, with 12 loudspeaker zones and 6000 W RMS power. The control is carried out from the DC-700ETH desktop microphone desks and from a computer equipped with the public address system configuration and management program. The loudspeakers in the installation, more than 300 units, are mostly powerful horn loudspeakers with high sound pressure for warehouses (AC-930EN), and ceiling loudspeakers for offices and common areas (A-225EN).
