  The short circuit isolator SCI is a device that disconnects the subsequent transmission line when a short circuit occurs in the subsequent transmission line. Usually, the signal transmission is not necessary, but the recovery signal is received from the distributed receiver RE1 and recovered. There are also things. Here, the recovery signal is transmitted when the short circuit of the subsequent transmission line is resolved.

  The smoke prevention control repeater C1 receives the control signal from the distributed receiver RE1 and controls the smoke prevention device DS1 connected thereto. The fire monitoring repeaters C2 and C3 are connected to a general-type sensor or a fire transmitter via a signal line, receive a fire signal (switching operation) from them, and transmit a fire signal. The fire monitoring repeater C2 can be connected to a fire detector with an automatic test function.

  The centralized receiver operation program 42, the distributed receiver operation program 43, and the distributed repeater operation program 44 are operation programs in a plurality of modes.

  FIG. 5 is a flowchart showing the processing of the basic program 41 stored in the flash ROM 40.

  First, the fire receiving devices RE1 and RE2 operate according to the basic program 41, execute the operation corresponding to the flowchart shown in FIG. 5, read the setting state of the dip switch SW1 when the power is turned on, and determine the mode. The operation program of the determined mode is acquired from the flash ROM 40 and operates.

  When the database in the memory card MC1 is read and stored in the RAM, the “type of fire receiving device” in the database is referred to, and if the setting of the dip switch SW1 does not match the database setting, that is, If the mode of the fire receiving device selected by the dip switch SW1 and the type of the fire receiving device in the database in the memory card MC1 do not match, the LCD 30 indicates that the setting of the dip switch SW1 does not match the database setting. To display. Then, the operation is stopped in that state, and an abnormal system that may cause a runaway due to a mismatch is not started.

  That is, the power is turned on (S1), the setting of the dip switch SW1 is read (S2), and if the setting content is the centralized receiver (S3), the DB (database) setting in the memory card MC1 is read and stored in the RAM. (S4) If the setting of the dip switch SW1 matches the DB setting, that is, if the type of the fire receiving device in the database is a centralized receiver (S5), the centralized receiver operation program 42 is acquired and executed. Then, it starts as a centralized receiver (S6). If the setting of the dip switch SW1 does not match the DB setting (S5), a message to that effect is displayed (S7). Then, the operation is stopped in that state, and an abnormal system that may cause a runaway due to a mismatch is not started.

  On the other hand, if the setting by the dip switch SW1 is not a centralized receiver (S3) but a distributed receiver (S11), the DB setting in the memory card MC1 is read and stored in the RAM (S12). If the setting of SW1 matches the DB setting, that is, if the type of the fire receiving device in the database is a distributed receiver (S13), the distributed receiver operation program 43 is acquired and executed as a distributed receiver. Start (S14).

  If the setting by the dip switch SW1 is not a distributed receiver (S11) but a main repeater (S21), the DB setting in the memory card MC1 is read and stored in the RAM (S22), and the setting of the dip switch SW1 is set. And the DB setting match, that is, if the type of the fire receiving device in the database is the main repeater (S23), the distributed repeater operation program 44 is acquired and executed, and the main repeater (distributed relay) (S24).

  Next, the fire receiving device performs a monitoring control operation by any one of the centralized receiver operation program 42, the distributed receiver operation program 43, and the distributed repeater operation program 44 based on the operation program acquired in S6, S14, or S24. I do.

  FIG. 6 is a flowchart showing the operation of the centralized receiver operation program 42 stored in the flash ROM 40.

  The state of the operation switch is read (S71), the state of the terminal device is read from the CTU boards B6 to Bn (S72), the display control according to the two states is performed (S74), and the CTU board control according to the two states is performed. (S75).

  FIG. 7 is a flowchart showing the operation of the distributed receiver operation program 43 stored in the flash ROM 40.

  Reads the status of the operation switch (S51), reads the status of the terminal device from the CTU boards B6 to Bn (S52), and reads the status of the fire receiver (distributed receiver / distributed repeater) from the LAN transmission board B5 (S53). Then, display control according to the three states is performed (S54), CTU substrate control according to the three states is performed (S55), and LAN transmission substrate control according to the three states is performed (S56).

  FIG. 8 is a flowchart showing the operation of the distributed repeater operation program 44.

  Reads the status of the terminal device from the CTU boards B6 to Bn (S62), reads the status of the fire reception device (distributed receiver / distributed repeater) from the LAN transmission board (S63), and controls the CTU board according to the above two statuses. (S65), and LAN transmission board control according to the two states is performed (S66).

As described above, the monitoring control operation of the terminal device performed through the transmission line (the above S52, S62, S72 and S55, S65, S75) is the fire receiver single mode (central receiver mode), the fire receiver Although common to the distributed mode (distributed receiver mode) and the distributed repeater mode, in the single mode of the fire receiver, disaster prevention information such as fire information is transmitted / received via a transmission line (LAN) (for example, S53 above) And S56) There is no need and no operation based on the received disaster information such as fire information is performed. In the distributed repeater mode, the operation related to the display operation on the panel surface (for example, the above S51 and S54) is unnecessary.
