This is a fire alarm system that sends a signal to the fire receiver. Normally, the fire receiver RE sequentially and cyclically specifies an address, and the terminal device returns status information of the terminal device corresponding to the specified address. By doing so, fire monitoring is performed.

When the fire receiver RE receives this return signal, a "normal signal" can be received from the terminal device at the previously designated address AD0, and the fire receiver RE recognizes that the terminal device is normal. Next, the address AD1 + “state information return instruction” is transmitted (SP3), and the repeater C11 to which the address AD1 is assigned responds to the “state information return instruction” and fires its own address AD1 + “normal signal”. When the fire receiver RE receives this return signal (SP4) and receives a "normal signal" from the terminal device at the address AD1, the fire receiver RE confirms that the terminal device is normal.

22 is a time chart showing an operation when the address 22 (address AD2) operates.

When the fire receiver RE sends out the address AD3 + “state information return command” (SP21), the repeater C12 of the address AD3 receiving the address AD3 sends the address P3 (address AD2) monitored by itself. Since it has operated, first, it transmits its own address AD3 and relay reservation information indicating a reservation for relaying the status information of the terminal device (lower-order terminal device) monitored by itself (SP2).
2) In order to indicate that the fire receiver RE that has received the relay reservation information acknowledges the start of the relay, the address AD

If the repeater C11 sends them separately in the order of "fire information" detected by E31, the address of the terminal device connected to the primary signal line L1 and the secondary device are connected to the secondary signal line L21. Even if the address of the terminal device and the address of the terminal device connected to the tertiary signal line L3 are overlapped,
The fire receiver RE identifies the terminal device that sensed the fire, and can recognize the state information of the terminal device.

That is, even when an address with a small number of bits is used, not only the terminal equipment connected to the primary signal line L1, but also the terminal equipment connected to the secondary signal lines L21 and L22, and the tertiary signal The fire receiver RE can know the status information of the terminal device connected to the line L3.

In this way, a large number of terminal devices can be monitored with an address having a small number of bits. In this case, if the second receiving unit collects in advance the state information of the predetermined terminal device before transmitting the state information of the predetermined terminal device to the first receiving unit, the state of the terminal device can be changed to the first state. Can be quickly recognized.

Further, after transmitting the relay reservation information as predetermined data together with the address of the second receiving unit, the address of the terminal device is transmitted as predetermined data together with the address of the second receiving unit. If the status information of the terminal device is transmitted as predetermined data together with the address of the receiving unit, the terminal device that has transmitted the status information can be reliably specified when transmitting the signal to the first receiving unit.

In response to the first receiving unit transmitting the address of the second receiving unit and the return command, the second receiving unit transmits the address of the second receiving unit and the relay reservation information to the first receiving unit. If transmitted to the receiving unit, the information transmitted after the relay reservation information is reliably recognized by the first receiving unit.
