The IC ceiling speakers of WORK PRO are suitable for Voice Alarm applications as they are certified according to EN 54-24. IC 656/54 is designed and made of 5VB plastic that prevents the fire from spreading in case of an emergency. The speaker can be easily installed using the speaker mounting spring in the panel.
This ceiling speaker series has a 70/100V transformer with different output power which brings clearer sound quality and reduces its mechanical loss (improving bass quality). It is suitable for offices, airports, restaurants, supermarkets or schools.
