IntroductionThis range of Ceiling-Mounted loudspeakers, intended for use in potentiallyexplosive atmospheres, has a power rating of up to 8 Watts (upon request)and is suitable for use in the harsh environmental conditions found offshoreand onshore in the oil, gas and petrochemical industries.

The lightweight, patented design provides self-supporting and self-lockingmounting onto a ceiling tile from 0.5 to 55mm thick. The speaker is held inthe mount via a twist-fit support and locking grille, giving access from aboveor below and allowing first fit of either ceiling or speakers. The DB20C’scompact design will fit a ceiling cavity of limited space and its aestheticallypleasing appearance will enhance the surroundings.
