"," Beep, beep, beep, fault of the slave unit "," beep, out of battery "," beep, beep, radio wave cannot be received "," Replacement period has passed. Please contact me. ", But not limited to these.

  The slave control unit 18b is configured to send a pairing request from the slave 10b to the master 10a, and is configured to be able to transmit a slave identifier signal to the master 10a.

  The slave unit-side inspection operation means 19b is a switch that receives an inspection process for checking whether the sensor devices and circuits of the slave unit 10b and the battery life are normal.

  The inspection operation means 19 (19a, 19b) of the present embodiment is configured to be able to execute a plurality of modes by operating the inspection operation means 19 for a predetermined time. Specifically, an inspection process is performed when the predetermined time is the first predetermined time, an alarm operation confirmation process is performed when the second predetermined time is set, and the pairing process is performed when the third predetermined time is set. In the case of the fourth predetermined time longer than the first to third predetermined times, the processing for canceling the processing for the inspection operation means 19 is performed.

When the predetermined time is the first predetermined time, as described above, the inspection process for checking whether the sensor devices, circuits, and battery life are normal is performed.
If the predetermined time is the second predetermined time, an alarm operation confirmation process is performed to determine whether the alarm function operates normally.
When the predetermined time is the third predetermined time, a pairing process for pairing the parent device 10a and the child device 10b is performed. The pairing process will be described later.
When the predetermined time is the fourth predetermined time, a process for canceling the process for the inspection operation means 19 is performed. This canceling process can be a process of canceling the above-described inspection process, alarm operation confirmation process, and pairing process.

  If the first to third predetermined times are set shorter than the fourth predetermined time, an arbitrary time can be set. The order of the first to third predetermined times is not limited. Since the operations for the first to fourth predetermined times are, for example, pressing operations on the inspection operation means 19 for a predetermined time, the user is configured to be able to identify them after each of the first to fourth predetermined times. It is possible. For example, after each of the first to fourth predetermined times, a different voice or a different number of “beep” sounds may be output.

As described above, in the alarm system X of the present invention, it is possible to shift to the pairing setting mode by operating the inspection operation means 19, so that there is no need to separately provide a pairing-dedicated switch, and the alarm system has a simple configuration. This is System X.
Further, by setting a plurality of different operation times for the inspection operation means 19, a plurality of processes can be executed by a single switch. Therefore, it is not necessary to separately provide switches corresponding to a plurality of processes, and the alarm system X has a simpler configuration.

  Further, the slave 10b may include a slave-side state display means 16b for visually displaying the state of the slave 10b with a lamp or the like. The slave unit side status display means 16b can be configured to display, for example, whether the power of the slave unit 10b is turned on / off, whether CO gas is detected, and whether or not a fire is detected, based on whether or not the LED lamp to which these are assigned is lit.

  By configuring the child device 10b in this way, when the child device 10b detects the leakage or the smoke of the CO gas, the child device 10b outputs an alarm sound S3b by the alarm device 15b on the child device side. That is, in normal times when no device failure (failure of the sub-unit side alarm unit 15b) has occurred, only the sub-unit 10b outputs an alarm sound based on an abnormality in the external environment detected by the sub-unit 10b.

  The alarm system X of the present embodiment is configured to perform a pairing process of one child device 10b with respect to one parent device 10a. A flowchart of the pairing process is shown in FIGS. The flowchart in FIG. 2 shows a flow in which a pairing request is sent from the child device 10b to the parent device 10a to perform a pairing process. FIG. 3 shows a flowchart of the parent device 10a in the pairing process at this time, and FIG. 4 shows a flowchart of the child device 10b.

  In the pairing process between the master unit 10a and the slave unit 10b, a pairing request may be sent from the master unit 10a to the slave unit 10b in addition to the pairing request sent from the slave unit 10b to the master unit 10a. The same pairing process may be performed in any case, such as when pairing is performed for the first time after installation or when pairing is canceled once after resetting. In the present embodiment, a case of resetting will be described.

  As shown in FIG. 2, by pressing the check operation means 19b for 10 seconds (third predetermined time), a pairing request is sent from the slave unit 10b to the master unit 10a to execute a pairing process. At this time, by outputting five “beep” sounds, the user can recognize that the pairing process is being performed. If the inspection operation means 19b is released within two seconds after this sound is output, the pairing reset mode is set (steps # 1 to # 4). If the pairing process described later succeeds, a “peep” sound is output, and if the pairing process fails, three “beep” sounds are output, so that the user can recognize the result of the pairing process. Yes (steps # 5 to # 8).

An outline of the master unit 10a at this time will be described (FIG. 3).
If the use channel (CH) is 58 and there is a pairing request from the child device 10b, it is determined whether or not pairing is possible based on the model information of the child device 10b accompanying the pairing request. If the models of the parent device 10a and the child device 10b correspond to each pairing, ACK transmission is performed to the child device 10b if they do not correspond to each other (steps # 101 to # 107).
If device information (wireless standard or the like) is received from slave unit 10b after ACK transmission, pairing becomes possible. In this case, master unit-side control unit 18a transmits a use channel and master unit identifier signal to slave unit 10b. I do. Further, the base unit-side control unit 18a checks the slave unit identifier signal as the setting completion signal sent from the slave unit 10b, and the master unit-side storage unit 14a stores the slave unit identifier signal. Thereafter, by performing ACK transmission to the slave 10b, a pairing process with the slave 10b can be performed (steps # 109 to # 115).
On the other hand, if the slave unit identifier signal as the setting completion signal sent from the slave unit 10b cannot be collated within 10 seconds, the master unit-side control unit 18a determines that the pairing process has failed (steps # 116 to # 116). 117).

An outline of the slave 10b at this time will be described (FIG. 4).
When the used channel (CH) is 58 and a pairing request is sent from the slave unit 10b (slave unit side control means 18b) to the master unit 10a and an ACK response is received within two seconds from the master unit 10a, the slave unit 10a The device identifier signal and device information (wireless standard etc.) are transmitted (steps # 201 to # 206). Thereafter, if there is an ACK response, a use channel, and a response of the master unit identifier signal within 10 seconds, the slave unit-side storage unit 14b stores the master unit identifier signal. Thereafter, if there is an ACK response within 10 seconds, the pairing process with the parent device 10a can be performed (steps # 207 to # 212).
On the other hand, if there is no ACK response within 10 seconds in # 207 and # 210, it is determined that the pairing process has failed (step # 213).

  Note that, at the time of a pairing request from the slave unit 10b, whether or not the pairing is possible may be determined based on the strength of the signal strength. Further, the present invention is not limited to the above-described embodiment, and the pairing process may be performed by sending a pairing request from master device 10a to slave device 10b.

  As described above, in the alarm system X of the present invention, by operating the inspection operation means 19, it is possible to shift to the pairing setting mode of the master unit 10a and the slave unit 10b, so that the pairing of the master unit 10a and the slave unit 10b is performed. There is no need to separately provide dedicated switches, and the alarm system X has a simple configuration.

  As described above, since the alarm system X of the present embodiment is configured to perform the pairing process of one child device 10b with respect to one parent device 10a, the pairing setting is surely performed. It can be carried out. If there are a plurality of slave units 10b for one master unit 10a, the pairing process of one slave unit 10b to one master unit 10a is performed for each slave unit 10b. It will be performed several times. Further, when trying to perform pairing processing of a plurality of slaves 10b with respect to one master 10a, a configuration may be adopted in which a pairing error is notified. In addition, pairing between slave units is not performed.
