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 656/54 loudspeaker is designed and manufactured from 5VB plastic, which prevents fire from damaging it in case of an emergency. It can be easily installed using the speaker mounting spring on the ceiling panel. This loudspeaker has a transformer that allows it to be installed in 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.
