The VWS-12-AB-W-EN is designed with two independent speakers and 100V transformers to enable an economic operation of two separated speaker lines (A/Blines) for highest security demands. In case of a failure of one speaker line the redundancy of the chassis and
the transformers will guarantee unimpaired function.
For additional reliability, a 2-pin-ceramic block, thermal fuses are provided and the speaker chassis are impregnated against wetness.
