Abstract: System for summoning service personnel to a particular table in a restaurant or similar facility and for monitoring service personnel response time. Each table includes a transmitter selectively activated by a switch at the table operated by a customer requiring service. When activated, each transmitter generates a signal unique to its table. A central station includes a display panel having a plurality of individual sections each relating to one of the tables. Each individual section includes a visual indicator, an audible annunciator, and a digital timer. The central station also includes a plurality of receivers, each responsive to one of the table transmitters. When a transmitter is activated by a customer, the corresponding receiver activates the appropriate visual indicator to alert service personnel that service is required at that table. Simultaneously the receiver causes the digital timer to count at one count per second.
