It is connected to contact input type gas leak monitoring panel D via F 1 and F 2 . The monitoring panel adapter C is
Outputs a voltage of E 0 (6V) and outputs E 1 when detecting a gas leak.
Assuming that the alarm output voltage of the voltage signal type gas leak alarm A that outputs a voltage of (12V; E 0 < E 1 ) is the power supply voltage, as shown in Fig. 3, the Zener voltage of E 0 < V 2 < E 1 is A Zener diode 3 with a voltage is connected to the base of the first stage transistor 4, the collector of the transistor 4 is connected to the base of the second stage transistor 7, and a relay is connected so as to be driven by the conduction of the transistor 7. 8 is connected, and the normally closed contact 8c of this relay 8 is used as an output contact.

い。 In this gas leak monitoring system, under normal conditions, the voltage signal type gas leak alarm A generates a voltage of 6V between terminals a and b, which is then applied to the terminal C of the monitoring panel adapter.
A base current is applied between a' and b' and flows into the transistor 7 through the diode 1 and the current limiting resistors 5 and 6, so that the transistor 7 becomes conductive.
Relay 8 is activated, normally closed contact 8c is opened, and terminals c and d are in an open state. Therefore, the terminals c' and d' of the contact input type gas leak monitoring panel D are also opened, the relay 9 does not operate, and its normally open contact 9c
remains open and the alarm indicator light 10 does not operate.

の警報表示灯１０が作動する。 Furthermore, when the voltage signal type gas leak alarm A detects a gas leak and generates a voltage of 12V between terminals a and b, this voltage is applied to the monitoring panel adapter C, and the Zener diode 3 becomes conductive. The base current flows into the transistor 4 through the diode 1, the resistor 2, and the Zener diode 3, making the transistor 4 conductive.As a result, the supply of base current to the transistor 7 is stopped, the transistor 7 is cut off, and the relay 8 is turned off. stops, the normally closed contact 8c closes, and the circuit between terminals c and d becomes closed. Therefore, contact input type gas leak monitoring panel D

る。 In this way, the gas leak monitoring system of this embodiment uses the monitoring panel adapter C to connect the voltage signal type gas leak alarm A to the contact input type gas leak monitoring panel D to monitor gas leaks. Moreover, the trouble detection function, which is a feature of the voltage signal type gas leak alarm device A, is not impaired. In addition, in the gas leak monitoring system shown in Fig. 1, only one voltage output type gas leak alarm A can be connected to one line of the voltage input type gas leak monitoring panel B; If there were a large number of devices A, it would be necessary to increase the number of lines accordingly, but in this embodiment, the voltage signal type gas leak alarm A and the contact input type gas leak monitor are connected via the monitoring panel adapter C. Since it is connected to panel D, any number of monitoring panel adapters C can be connected to one line of gas leak monitoring panel D.
Correspondingly, a voltage signal type gas leak alarm device A can be connected, and therefore the number of lines can be reduced, and the number of windows of the contact input type gas leak monitoring panel can be reduced.
