A signalling system serving for controlling the service at a restaurant where a guest at a counter can order a product, such as a hot meal for later handing over. The system comprises at least one transmitter (4) arranged to, upon operation of the keyboard (2) on a remote control (1), emit wireless signals (15) which represent a number of predetermined codes; and a number of indicators (5) each having its own receiver which is precoded individually with one of the codes for, upon receipt of a wireless signal representing the respective code, activating a caller belonging to the indicator to, with a sound and/or light signal, call a guest who has been given the indicator in question in connection with his order. Thereby, a more secure, effective and convenient control of the service than known so far is thereby obtained without any inconvenience to the guests present. |
