Embodiments of the present invention will be described below. Here, the interlocking control first voltage level corresponds to the first interlocking control signal, and the interlocking control second voltage level corresponds to the second interlocking control signal.
However, these control signals are not limited to voltage signals, and any kind of signals such as digital signals, analog signals, and data signals can be used.

  FIG. 1 is a diagram showing an example of a schematic configuration of the system of the present invention. This is configured by connecting a plurality of residential fire alarms 1 operated by a commercial power source in parallel to a two-wire signal line L, but is not limited to a two-wire signal line. Any signal transmission can be used.

  Each residential fire alarm 1 has a function of detecting fire factors such as smoke and heat. When each fire alarm 1 detects a fire factor, the alarm 1 outputs a fire alarm by an alarm sound output or the like. At the same time, the interlock control first voltage level is output to the two-wire signal line L, and the interlock alarm is output from all the other fire alarm devices 1. This interlocking alarm also outputs an alarm sound in the same way as a fire alarm.

  Each fire alarm 1 has an internal configuration as shown in FIG. That is, a power supply circuit 10 that receives a commercial power supply and generates an operating power supply, a control signal output unit 11 that outputs any one of a normal monitoring voltage level, a linked control first voltage level, and a linked control second voltage level, and this fire A control unit 12 for controlling the alarm device 1, a fire detection unit 13 for detecting a fire factor such as smoke and heat, a control voltage monitoring unit 14 for monitoring the two-wire signal line L and determining its voltage level; , An alarm circuit 15 for outputting an alarm output (fire alarm, interlocking alarm) by an alarm sound or the like under the control of the control unit 12, a response processing circuit 16 for performing first and second fire alarm response processes to be described later, and a response Provided independently of the processing circuit 16 and having an individual interlocking alarm stop button 17A, the fire alarm device 1 alone includes an individual interlocking alarm stop circuit 17 for stopping the interlocking alarm output.

  The control unit 12 includes a counter 12A that is used in processing that will be described later, and a timer 12B that is also used in processing that will be described later. The timer 12B includes a timer A used for a first fire alarm response process described later and a timer B used for stopping an individual interlock alarm described later. In addition, the response processing circuit 16 is provided for performing the first and second fire alarm response processes as described above. Specifically, the first response to the alarm device that performs the interlocking alarm is provided. In the fire alarm response process, the interlock alarm is stopped and the volume / sound quality change of the interlock alarm is performed. In the second fire alarm response process for the alarm device performing the fire alarm, as a circuit for changing the volume / sound quality of the fire alarm Function.

  In the first fire alarm response process, when only the alarm device 1 performing the interlocking alarm is stopped, the interlocking alarm stop circuit functions. This circuit 16 has a response processing button 16A as the interlocking alarm stop. A button is provided. In addition, when only the alarm device 1 that performs the interlocking alarm is to change the volume / sound quality of the interlocking alarm, it functions as an interlocking alarm sound volume / sound quality changing circuit. A button is provided. On the other hand, in the second fire alarm response process, only the alarm device 1 that gives a fire alarm functions as a fire alarm volume / sound quality changing circuit when changing its volume / sound quality, and this circuit 16 has a response processing button 16A. A fire alarm volume / sound quality change button is provided.

FIG. 3 shows a specific configuration example of the control voltage output unit 1 . In the control voltage output unit 11, the power supply voltage V generated by the power supply circuit 10 is rectified by the resistor R and the diode D, and the voltage generated by the following processing is converted into the normal monitoring voltage level V1 and the interlock control first voltage level. V2 is output to the terminals 1 and 2 as the interlock control second voltage level V3. That is, the switching circuit 11C that operates according to the output instruction of the interlocking control first voltage level V2 from the control unit 12 (instruction of interlocking alarm output) is connected between the terminals 1 and 2 by the Zener voltages of both the Zener diodes ZD1 and ZD2. The voltage is lowered, and the potential difference between the terminals 1 and 2 is set to V2. As a result, the interlock control first voltage level V2 is output to the two-wire signal line.

Further, the switching circuit 11B operates in response to the output instruction (fire response processing instruction) of the interlock control second voltage level V3 from the control unit 12, and the voltage at the terminals 1 and 2 is set to V3 by the Zener voltage of the Zener diode ZD1. . As a result, the interlock control second voltage level V3 is output to the two-wire signal line. The interlock control first voltage level V2 is output until a predetermined time by a timer (not shown) different from the timers A and B elapses due to the latch function of the latch circuit 11A.

  Next, characteristic processing of such a configuration will be described with reference to the flowchart of FIG. That is, if the fire alarm 1 detects a fire factor, it outputs a fire alarm and outputs the interlock control first voltage level V2 (100 to 102).

  On the other hand, when the fire factor is not detected, if the timer A that is actuated by a trigger described later is in operation, the response processing button 16A is operated, so the interlock control second voltage level V3 is output ( 103, 104).

  Furthermore, when the fire factor is not detected and the timer A is not operating (100, 103), the fire alarm device 1 is not outputting the interlock alarm, and in such a state When it is determined that the interlock control first voltage level V2 is output from another fire alarm device 1 (106), the following operation is performed.

  That is, if the timer B operated by a trigger described later is not in operation (111), the interlock alarm output is not performed, and thus when the response processing button 16A is operated in this state (107) Then, the timer A is activated for a predetermined time (108), the interlock alarm output is started, and the routine proceeds to step 100.

  On the other hand, when the response processing button 16A is not operated (107) and the individual interlock stop button 17A is operated (109), the timer B is started for a predetermined time (110). If timer B is running (111), the interlocking alarm is stopped only during that time, and the process returns to step 100. On the other hand, if the timer B is not activated, the interlock alarm output is started and the process returns to step 100.

FIG. 5 shows voltage level transition on the two-wire signal line L in the processing of such a flowchart. That is, in the normal state, the potential difference between the interlocking signal output terminals T1 and T2 is the normal monitoring level V1. Now, when a certain fire alarm device 1 detects a fire factor, the alarm device 1 outputs the interlocking control first voltage level V2 to the two-wire signal line L, so the voltage value of the two-wire signal line L Becomes V2. When the response processing button 16A is operated on the alarm device 1 that outputs the interlocking alarm, the interlocking control second voltage level V3 is output, so the voltage value of the two-wire signal line L becomes V3.
Note that the interlocking control second voltage level V3 may be transmitted as a one-shot pulse for a predetermined time as shown in FIG.
In this case, the fire alarm 1 operates as shown in the flowchart of FIG. That is, if the fire alarm device 1 detects a fire factor, it outputs a fire alarm and outputs the interlocking control first voltage level V2 (200 to 202).

On the other hand, if the fire factor is not detected, the interlock control second voltage level V3 is determined (203). If the interlock control second voltage level V3 is determined, the timer A is started and the routine returns to step 200 (204). On the other hand, if the interlock control second voltage level V3 cannot be determined (203), the interlock control first voltage level V2 is determined (205). As a result, if the interlock control first voltage level V2 can be determined, the following processing is performed. That is, if the response processing button 16A is operated in that state (206), the interlock control second voltage level V3 is output as a one-shot pulse (207). If the individual interlock stop button 17A is not operated (208) and the timer A is operating (210), the interlock alarm is stopped during this period (213), and the routine proceeds to step 200.
On the other hand, when the individual interlock stop button 17A is operated (208), the timer B is started, the question during the operation is stopped for interlocking alarms (211 and 213), and the process proceeds to step 200.
As an advantage of outputting the interlock control second voltage level V3 as such a one-shot pulse, when the fire alarm device 1 operates by receiving power supply from another alarm device 1, the interlock control second voltage level is obtained. If V3 is set to 0V, the Zener diode ZD1 of the control voltage output unit 11 can be made unnecessary, and the number of parts can be reduced.

Furthermore, the fire alarm device 1 having such a configuration is a response alarm circuit 16 as a response alarm circuit / sound quality change circuit, and the alarm device 1 that has determined the interlock control second voltage level V3 does not stop the alarm. Alternatively, the volume of the interlocking alarm may be reduced or the sound quality may be changed. The basic operation is the same as that in the flowcharts of FIGS.
The fire alarm device 1 configured as described above is a fire alarm volume / sound quality change circuit that changes the sound volume / sound quality of the alarm device 1 that outputs a fire alarm as the response processing circuit 16. When the alarm device 1 performing the alarm determines the interlock control second voltage level V3, the volume and sound quality of the fire alarm may be changed.

  This process will be described with reference to FIGS. FIG. 8 shows a type of processing in which the interlocking control second voltage level V3 is continuously output for a predetermined time as shown in FIG. The fire alarm device 1 outputs a fire alarm if a fire factor is detected (300), but if the interlock control second voltage level V3 is discriminated from other fire alarm devices 1 (301), the above-described second alarm is output. Fire alarm response processing is performed. That is, the output sound of the fire alarm is increased or the sound quality is changed (302), and then the interlocking control first voltage level V2 is output to the two-wire signal line (304).

On the other hand, if the interlock control second voltage level V3 is not determined when a fire factor is detected, a fire alarm is output as it is without increasing the output sound (303). On the other hand, if the fire factor is not detected (300), if the interlock control first voltage level V2 from another fire alarm 1 is determined (305), the interlock alarm is output (313). When the response processing button 16A is operated, the timer A is started, and during the operation, the interlock control second voltage level V3 is output (306, 307, 310, 311). Further, when the individual interlock stop button 17A is operated during the output of the interlock alarm, the timer B is started, and the interlock alarm is stopped during the operation (308, 309, 314).

On the other hand, if the interlock control first voltage level V2 is not detected when no fire is detected, the interlock alarm is stopped if the interlock alarm is output (314).
On the other hand, as shown in FIG. 6, FIG. 9 shows a type of processing in which the interlock control second voltage level V3 is output as a one-shot pulse.
That is, the fire alarm device 1 outputs a fire alarm when a fire factor is detected (400). While the fire alarm is being output, the interlock control second voltage level V3 from the other alarm devices 1 is output. Is determined, the timer A is activated as the second fire alarm response process, and during the operation, the alarm sound is increased or the sound quality is changed (401, 402, 403, 405).
On the other hand, when the interlock control second voltage level V3 is not discriminated, a fire alarm is output as it is with a normal alarm sound (404). Thereafter, the interlocking control first voltage level V2 is output to the other fire alarm device 1 (406).

On the other hand, when the fire factor is not detected (400), when the interlock control first voltage level V2 from the other fire alarm device 1 is determined (407), the interlock alarm is output (413). When the response processing button 16A is operated during the interlock alarm output, the interlock control second voltage level V3 is output as a one-shot pulse (408, 409).
When the individual interlock stop button 17A is operated during the interlock alarm output, the timer B is started and the interlock alarm is stopped during the operation (410, 411, 412, 414). On the other hand, when the interlock control first voltage level V2 or the interlock control second voltage level V3 is not detected in the state where no fire is detected, the output of the interlock alarm is stopped (414).
When performing these processes, the control circuit 12 uses the counter 12A to count the number of outputs of the interlock control second voltage level V3, the number of determinations, or the number of operations of the individual interlock alarm stop button 17A. When the predetermined number of times is reached, the output of the interlock control second voltage level V3 may be invalidated or the discrimination of the interlock control second voltage level V3 may be invalidated. Furthermore, the operation of the individual interlocking alarm stop button 17A may be invalidated.

  In addition, by determining the second voltage level of the interlock control, the timer A operating time is sequentially shortened each time the fire alarm volume / sound quality changes, the interlock alarm stops, or the interlock alarm volume / sound quality changes. Also good. That is, the response processing time defined by the timer A is sequentially reduced every time the interlock control second voltage level is determined and the fire alarm response process is performed. Furthermore, a timer for measuring the latch time of the latch circuit 11A of the control voltage output unit 11 may be provided, and the output time of the interlock control second voltage level may be shortened sequentially according to the number of outputs. The individual interlocking alarm stop processing is performed for the time specified by the timer B. For the purpose of sequentially visiting the place where the alarm device 1 is installed and identifying the fire source, the individual interlocking alarm stop button 17A is operated. Then, the interlocking may be stopped without time limitation. In that case, the timer B becomes unnecessary.
