That is, this alarm repeater X 1 has a pair of power supply side terminals 1a, 1b, load side terminals 2a, 2b, and output terminals 3a, 3b, and the power supply side terminal 1a is used as the positive side of the DC power supply. There is. The internal circuit consists of a voltage detection circuit and a notification circuit, and the voltage detection circuit has a reverse current blocking diode DD1 connected in the forward direction between terminals 1a and 2a of the same polarity, and a voltage dividing resistor connected in the forward direction between terminals 1b and 2b. A series circuit consisting of R 1 , a voltage setting resistor R 2 , and a light emitting diode LED for disconnection detection is connected. In addition, a series circuit consisting of a relay R y for supplying the monitoring board of the notification circuit and a transistor T r for voltage detection is connected in the forward direction between the terminals 1 a and 1 b via the diode DD 1 , and the base of the transistor T r is connected to the zener.

そのため、リレーRyが作動しリレー接点ryが閉成
し、受信回路Zaが閉成される。 Figure 4 shows a monitoring system in which a contact type alarm Y1 is applied to this repeater. That is, a parallel circuit of the sensing contact r g of the alarm Y 1 and the terminating resistor R is connected between the load side terminals 2a and 2b of the repeater A DC power source F is connected, and output terminals 3a and 3b are connected to a receiving circuit Z a of a central monitoring board Z. P is the alarm's commercial power plug. In this system, the detection contact r g is open at all times, that is, when the gas leak detection is on standby, and the diode is connected by the DC power supply F.
Current flows through DD 1 , terminating resistor R, voltage dividing resistor R 1 , voltage setting resistor R 2 , and light emitting diode LED.
Since the voltage V appearing across the resistor R 2 and the light emitting diode LED is set smaller than the Zener voltage V ZD of the Zener diode Z D , the transistor T r is off and therefore the relay R y does not operate. On the other hand, when the alarm Y 1 performs a gas leak detection operation, the sensing contact r g is closed and the terminating resistor R is short-circuited, and as a result, the voltage V appearing on the resistor R 2 and the light emitting diode LED becomes high, and the zener By setting the Zener voltage to be higher than the Zener voltage of the diode Z D , the base current flows through the transistor T r and turns on the transistor T r .
Therefore, relay R y is activated, relay contact ry is closed, and reception circuit Z a is closed.

るので、断線検出となる。 In addition, the light emitting diode LED is lit at all times and when a gas leak is detected, and turns off when the alarm line is disconnected, so a disconnection is detected.

イオードLEDの動作は前記と同様である。 FIG. 5 shows a monitoring system in which a voltage alarm Y2 is applied to the repeater X1 . In this case, connect the power supply side terminals 1a and 1b to the output terminal of the alarm Y2 , and short-circuit the load side terminals 2a and 2b with the shorting wire SH (connect a resistor considering the voltage appearing on the resistor R2 ). ). Since the alarm Y 2 normally outputs a voltage of 6V DC, the voltage V appearing on the resistor R 2 and the light emitting diode LED is lower than the Zener voltage, but when a gas leak is detected, a voltage of 12V DC is output from the alarm Y 2 . Therefore, the voltage V can be greater than the Zener voltage, so that the transistor T r is turned on and the relay R y is activated. The operation of the light emitting diode LED is the same as described above.

なる。 Because of this configuration, this alarm repeater can, for example, set the DC power supply F to 12V DC and set the partial voltage of the terminating resistor R to 6V . No matter which method is applied, the voltage appearing on the resistor R 2 and the light emitting diode LED can be set to be the same before and after the sensing operation, and the Zener voltage must be set so that there is a voltage difference between the voltages appearing before and after the sensing operation. This means that it can be used in common for two types of alarm devices.

That is, in the first embodiment, this alarm repeater X 3 connects the buzzer B Z and the sensing light emitting diode LED 1 in parallel to the relay Ry to form an alarm circuit, and these are connected as shown in FIG. It is installed on the two-piece switch plate T of repeater X 1 to notify which room in the hallway is leaking gas. R3 is a diode current limiting resistor.
