WORK PRO IC ceiling loudspeakers comply with the EN 54-24 emergency safety standard (Fire alarm and fire detection system) so they can be used in evacuation systems. The IC 6520/54 loudspeaker is designed and manufactured from 5VB plastic that prevents fire from damaging it in the event of an emergency. The speaker can be easily installed using the speaker mounting spring on the ceiling panel. This loudspeaker has a transformer that allows it to be installed under high impedance lines (70 / 100V) offering a great sound quality. Its use is ideal for installation in spaces such as offices, airports, restaurants, supermarkets or schools.
