The unit circuit corresponding to each transmitter 2 includes a connection circuit section 10, a display section 16, a response calling circuit section 26, and a notification sound generation section 18. In the following description, a unit circuit corresponding to the transmitter 2 ₁ shown at the top of the main device 1 in FIG. 2 will be explained as an example. The connection circuit section 10 consists of a call detection section as a call detection means and a short circuit protection circuit section, and the call detection section detects the pressing operation of the call button 6 of the transmitter 2, that is, in the case of this embodiment, the main device 1 When the line connecting the and transmitter 2 is short-circuited, for example between T ₁₁ and T ₁₂ , the operating state of the call button 6 is detected by detecting the current flowing between the two lines, and the transistor Q ₃ , _Q4 , and resistors _R1 , _R2.The short-circuit protection circuit section prevents the constant voltage section 8 from being destroyed when the call button 6 is pressed. ₂ , a diode _D1 and a resistor _R3 . Note that the constant voltage from the constant voltage circuit 9 is connected between T ₁₁ and T ₁₂ by the transistor Q ₂
and a resistor R ₁ , and the constant voltage section 8 and the connection circuit section 10 constitute a constant voltage means for individually applying a constant voltage between the signal lines. Display section 16
is lit for an arbitrary period of time after the call button 6 is operated, and turns off naturally after this time has passed to indicate which transmitter 2's call button 6 has been operated. ₃ Inverter I that inverts the output, diode D ₂ , resistor R ₅ ,
It consists of a capacitor C ₁ , a capacitor C ₂ common to each unit circuit, and a resistor R ₆ . The notification sound generator 18 emits a notification sound while the call button 6 is pressed, and the basic oscillation circuit 19 that determines the sound of the buzzer 5 and the call button 6 of any of the transmitters 2 are pressed. The switch circuit 20 includes a transistor Q6, which applies the output of the basic oscillation circuit 19 to the buzzer ₅ to cause the buzzer 5 to sound when a signal is generated, and a switch circuit 20 including diodes _D10 to _D13 . In this embodiment, the display section 1 and the notification sound generating section 18 constitute a notification device that notifies the call from the transmitter 2 by the detection output of the connection circuit section 10 as a call detection means. The response call circuit section 26 consists of response call buttons 21 ₁ to 21 ₄ and a transistor Q ₅ that are operated when calling the transmitter 2 or when a call is received from the transmitter 2, and in order to call the transmitter 2, Alternatively, when responding to a call from the transmitter 2, the output of the basic oscillation circuit 19 is transmitted to the transmitter 2 via the connection circuit section 10 to cause the buzzer 22 of the transmitter 2 to sound. Here, in this embodiment, when any of the response call buttons 21 is operated, a call signal or response signal is sent out via the signal line, and a ring tone or response is generated from the buzzer 22 as a notification device of the corresponding transmitter 2. A response sound sending means for generating a sound is composed of a basic oscillation circuit 19, a response calling circuit section 26, and a connection circuit section 10.

The operation of this embodiment will be explained below. First, assume that a certain call button 6 is pressed to call a member of a family member who is present at the main appliance 1 installed in the kitchen, for example. When the call button 6 of the transmitter 2 is pressed, the wires connecting the main device 1 and the transmitter 2 are short-circuited. Due to this short circuit caused by the call button 6, the current flowing through the resistance _R1 of the transmission detection section increases. Therefore, the voltage across the resistor _R1 increases, turning on the transistor _Q4 , and turning on the transistor _Q4 turns on the transistor _Q5 . At this time, the output inverted via the inverter I becomes a low level, so the display section 1 corresponding to the pressed call button 6
6 indicator light 3 lights up. Note that this display section 16
The indicator light 3 is connected to the display unit 16 as shown in FIG. 3q.
The operation continues until an arbitrary time T seconds set by the time constants of the capacitors C ₁ and C ₂ and the resistor R ₆ elapses, or until the response call button 21 is pressed as shown in j to l of the figure. It continues to light up as shown in n to p.
In the notification sound generating section 18, when a call is received from any of the transmitters 2, the transistor _Q6 becomes conductive, thereby applying the output of the basic oscillation circuit 19 to the buzzer 5, and causing the buzzer 5 to generate a ringing sound. Note that the buzzer 5 is designed to emit a notification sound only while the call button 6 is pressed. Figure 3 a, c, e, g
When the call button 6 is pressed as shown in FIG.
The buzzer 5 sounds as shown in FIG. i in accordance with the pressed state of each call button 6. Then, when a person in the room where the main device 1 is installed hears this notification sound and presses the response call button 21 as shown in FIG. The output is applied to the transmitter 2 via the answering circuit section 26 and the connecting circuit section 10, and the buzzer 22 of the transmitter 2 sounds as shown in FIGS. 3b, d and f. Therefore, the person who made the call can confirm from this response tone that the person on the main device 1 side has noticed the call. Note that when the response call button 21 is pressed as shown on the right side of FIG. The buzzer 2 of the transmitter 2 is activated as shown in d and h of the same figure.
By ringing 2, a person on the side of the transmitter 2 can be called.
