Light call installation for hospital etc.

摘要

The installation transmits a call signal from a terminal to a central unit. The call signal is transferred to a personnel paging device (14) which transmits wirelessly to one or more receiver units (15). The central unit (12) includes a switch-in module (20) which is configured so that confirmation information returned from a receiver unit (15) back to the central unit can also be transferred back to the terminal (11).
