Abstract

PURPOSE:To prevent a subordinate station in an engagement state from being reset owing to the malfunction of a reset switch which resets the subordinate station in response to a control signal sent from a master station, by disabling the reset switch to operate when the operation switch of the subordinate station is left turned off forgetfully. CONSTITUTION:The master station is provided with transmitter-receiver 1 and connected to the subordinate station by radio, and the subordinate station is connected to line wires via the master station and usable as an interphone. The master station, when used as an interphone, excits relay RY-1 to set a transmission state and then excits relay RY-2 to make a circuit connection with the subordinate station. The subordinate station is connected to the master station through the operation of an answer switch. If the answer switch of the subordinate station is not operated again by mistake after the calling service, the master station is still in interphone mode and tone signal f3 is transmitted by closing reset switch 28 to operate the vibrator of the subordinate station, resetting FF. When the subordinate station is connected to the line wires, the master station is connected in response to tone signal f2 from the subordinate station to prevent malfunction.
