PURPOSE:To simplify the connection system by registering previously the number of an optional subscriber telephone or the telephone number of the fire station to the telephone set and then informing the fire occurrence to the registered subscribers without performing the dial sending when the fire detector installed within the private house operates. CONSTITUTION:The repeating system comprises subscriber telephone sets TELA and TELB, fire detector S, subscriber line L, exchange network NW, subscriber circuit LR, oscillation register OR, marker MRK, memory device MEM, message trunk MTRK and aural response unit ARE each. Thus subscriber A gives call through telephone TELA and stores the connection destination number in memory M via circuit LR, network NW and register OR each. After this the handset is put down to actuate detector S. Under these conditions, if the fire breaks out and detector S operates, unit ARE which stored previously the information to be informed operates to transmit the message of the fire occurrence to telephone TELB at the fire station or the like. |
