Highlights:
The Bosch LBB 1957/00 keypad is an extension to the LBB 1956/00 Plena Voice Alarm Call Station that adds seven additional zone-select keys. The LBB1957/00 has the same stable metal base as the call station. In addition to tabletop use, the special design allows it to be neatly flush-mounted in desktops.
