Help with wiring a toxic gas detector

I would like to ask the experienced technicians: to which terminals should the red and black wires of the sound and light alarm be connected? Should I connect to the two terminals for higher voltage or to the two terminals for power? Personally, I think the two terminals that connect to the 24V power supply

The audio-visual alarm has gone off, which indicates that the value has exceeded the standard limit; it should trigger a high-level alert

Is the acoustic and optical alarm itself 24V or 220V? If it is 24V, it should be connected directly to the two terminals of the H alarm; if it is 220V, a separate 220V power supply needs to be provided for the alarm. Of course, it’s necessary to check the specific instructions; these two alarm points might also be dry contacts, in which case 24V needs to be connected in series within the 24V alarm circuit.

According to the high-level report, it was just repaired; it shows zero, and the lights and sounds are indicating an alarm

An audio-visual alarm generally has three wires: a signal wire, a power wire, and a common terminal. If it is confirmed that there are only two wires, then they should be terminals 7 and 8, which correspond to the high alarm signal

Are there any particular rules regarding how to connect the red and black wires? Just connect it to the two terminals marked as high voltage, right?
