To enable its loudspeakers to be used in voice alarm systems in venues across Europe, Community Professional Loudspeakers has applied for EN54-24 certification—which specifies the minimum requirements for voice alarm loudspeaker as a component of a voice alarm system to provide intelligible warning when a fire emergency has occurred and provides a common method of testing their operational performance—of many of its large-scale loudspeaker systems through the international laboratory network of European Notified Body, Intertek. Intertek’s newly opened Life Safety & Security testing facility in Leatherhead, U.K., had been developed to accommodate larger products used in fire detection and evacuation and had the capacity to test Community’s loudspeakers, which weigh between 88.2lbs. and 319.7lbs. Intertek’s acoustic chamber enables test engineers to take audio readings at 13.1233ft. (4 meters) as required by EN54-24, and the company’s 998cm3 SO2 corrosion chamber (double the size of most corrosion chambers operating) is capable of conditioning larger products to simulate environmental aging.
