Loudspeaker cover
The optional speaker cover is made of fireproof material. In case of fire, the ceiling holes with loudspeakers can spread the fire throughout the building. In order to prevent the fire from entering the ceiling through the loudspeaker, the ceiling speaker can be equipped with a protective plastic speaker cover (LBC 3083 / 50). The optional speaker guard is mounted on the mounting frame by rotating operation and locked by special clamps. There are four reserved holes; two (2) for rubber gasket and two (2) for cable gland.
qa
All Bosch loudspeakers comply with IEC 268-5 maximum output power (PHC) standard and can operate at rated power for 100 hours. In addition, Bosch has developed a simulated sound feedback exposure (SAFE) test to show that its loudspeakers can operate at twice the rated power in a short period of time. At the same time, it also provides additional reliability for loudspeakers to work under harsh conditions, which not only improves customer satisfaction, extends service life, but also reduces the probability of failure or performance degradation.
Security
Like all Bosch products, the design is constantly improving to meet high safety standards.
The enclosure complies with the relevant safety and installation specifications of EN 60065.
