OPTIMUS, the leading Spanish company in the design, manufacture and distribution of public address (PA), voice alarm (VA) and intercom equipment.
The A-252BTM ceiling speaker occupies minimal space when embedded in false ceilings; the white grille of only 10.3 cm in diameter facilitates its discreet installation practically anywhere and its integration with the architectural environment of the enclosure. Despite its small size, this speaker includes a 100 V line transformer, three power tabs and a mechanical system for recessing easily on the ceiling, and is suitable, for example, for hotel corridors, small fashion stores or restaurants.
