Zusammenfassung: | PURPOSE:To attain telephone call having a high energency function without disconnecting the calling state suddenly by sending a message to a speaker at the generation of emergency information. CONSTITUTION:If a telephone set 23 is an object to receive emergency information, telephone sets 4, 24 generate emergency information through a telephone circuit 1 in calling and a sensor in an emergency information part 17 is started, a switch 21 is closed and the 2nd voice generating part 13 is started. Since the voice generating part 13 sends the message once or plural times, the message is sent to the telephone set 4. When a speaker hooks a transmitter/receiver, a detecting element 3 detects the hooking and sends the detected result to a control part 15. The control circuit 15 sends a control signal to the emergency information part 17 and switches relay contacts 2A, 2B to inform the emergency to the terminating telephone set 23 to be informed at the emergency. |
