  However, in the sound stop device of Patent Document 1, once set to the sound continuous stop function (continuous sound stop function), the sound continuous stop function (continuous sound stop function) is canceled unless the receiver is reset. However, even if the situation is such that the sound is completely stopped and an alarm must be performed after the sound is stopped, the alarm is stopped, which is a serious safety problem.

  The present invention makes it possible to set a continuous sound stop function (continuous sound stop function) for the first time when a sound device such as an emergency bell (district sound) really rings and wants to stop it. Even after the sound continuous stop function (continuous sound stop function) is set, if a predetermined condition newly occurs, the sound stop device immediately (continuous sound stop function) An object of the present invention is to provide an acoustic stop device for a fire alarm facility capable of releasing an acoustic stop function.

In order to achieve the above object, an invention according to claim 1 has an operation panel provided with a plurality of operation means, wherein a plurality of fire detectors and sound devices are connected via a plurality of district lines, In the sound stop device of the fire alarm facility equipped with a receiver that issues a fire alarm when a fire detection signal is input from any of the multiple district lines,
Wherein in situations where the acoustic device is ringing in response to the sound Hibikitoma stop operation means provided on the operation panel is operated, and audio-continuous stop function of stopping continuously the acoustic device, When a fire detection signal is input to the receiver from a plurality of district lines when the sound stop operation means is operated, setting of the sound continuous stop function is prohibited and the sound continuous stop function is set. even after being, if fire detection signal is inputted from a plurality of section lines or new district lines, and characterized in that it is immediately releasably constituting the acoustic continuous stop function.

The invention according to claim 2 is the sound stop device of the fire alarm facility according to claim 1, wherein the sound stop operation means provided on the operation panel is in a state where the sound device is ringing. A continuous sound stopping function for stopping the sound device continuously for one hour or longer in response to an operation, and a sound stop function for stopping the sound device for a time shorter than 10 minutes, Is set by operating the acoustic stop operating means for a predetermined time or more, and the setting of the acoustic pause function is performed by operating the acoustic stop operating means for a time shorter than the predetermined time. It is configured as described above.

According to a third aspect of the present invention, in the sound stop device for the fire alarm facility according to the first or second aspect , the set sound continuous stop function is canceled when the sound stop operation means is operated again. It is characterized by being.

According to a fourth aspect of the present invention, in the sound stop device for a fire alarm facility according to any one of the first to third aspects, the receiver includes a display unit, and the sound continuous stop function is set. If it is, the state in which the acoustic continuous stop function is set is displayed on the display unit.

According to the first to fourth aspects of the invention, it is possible to set the sound continuous stop function (continuous sound stop function) for the first time when the sound device really rings and wants to stop it. Even if the sound continuous stop function (continuous sound stop function) is set, if a fire detection signal is output from multiple district lines, the sound stop device immediately Even after the stop function (continuous sound stop function) is canceled or the continuous sound stop function (continuous sound stop function) is set, a fire detection signal is output from the new district line. In such a case, the acoustic continuous stop function (continuous acoustic stop function) is immediately canceled, so that even after the acoustic continuous stop function (continuous acoustic stop function) is set, the predetermined condition is newly set. If it occurs in It can immediately release the acoustic continuous stop function (continuous sound stop function).

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  Conventionally, when an acoustic device such as an emergency bell (district sound) rings as a sound stop device provided in a fire receiver of a fire alarm facility, receiving a fire detection signal from a fire detection means such as a fire detector In addition, if it can be confirmed that the detection signal is due to a malfunction of the sensor and not a fire, the district sound temporary stop switch provided in the operation unit (operation panel) of the receiver There is a known device that operates to temporarily stop the sound of the sound device.

  The temporary stop by this district acoustic stop switch is designed to prevent a continuous stop for the purpose of preventing escape delays due to no alarms, and when the predetermined time (2 to 10 minutes) elapses, the stop state is canceled. The sound device is automatically restored to a state in which it can ring.

  Therefore, if the fire detection signal from the fire detection means such as a fire detector is based on a fire, such an operation may be performed, but the fire detection signal is based on a malfunction of the fire detection means such as a fire detector. If the cause of malfunction is not removed, the sound device will ring again after a predetermined time (2 to 10 minutes) even if the district sound temporary stop switch is operated. The operation cannot be stopped unless the temporary stop switch is operated, and the continuous stop cannot be performed.

  If this is a place where the fire alarm facility is installed, such as an office building, where people can enter the fire detector installation area relatively freely, and at night, where there are no people Even if the sound device rings again after a predetermined time (2 to 10 minutes) after operating the district sound stop switch in this way, it is relatively easy to eliminate the cause of false alarms, If the sounding device continues to ring at night, it is not likely to cause confusion.

  On the other hand, if the fire alarm facility cannot easily enter the place where the fire detector is installed, such as a condominium, such as a condominium, etc. It is extremely difficult to remove the cause, and if the sound device rings again after a predetermined time (2 to 10 minutes) after operating the district sound stop switch as described above, especially at night when the resident is asleep. In, the sound device keeps ringing, causing a great deal of confusion.

  However, if the sound stop function of the sound stop device is expanded, it may cause a delay in escape due to no alarm when a fire occurs.

  The above-mentioned Patent Document 1 solves such a problem, and as described above, it is the first time that an acoustic device such as an emergency bell (district sound) really rings and wants to stop it. The continuous acoustic stop function (continuous acoustic stop function) can be set, and the continuous acoustic stop function (continuous acoustic stop function) cannot be set in advance from normal times. Thereby, easy abuse of the continuous acoustic stop function can be prevented.

  However, in the sound stop device of Patent Document 1, once set to the sound continuous stop function (continuous sound stop function), the sound continuous stop function (continuous sound stop function) is canceled unless the receiver is reset. However, even if the situation is such that the sound is completely stopped and the alarm must be performed after the sound is continuously stopped, the alarm is stopped, which is extremely problematic for safety.

  Therefore, the present invention can set the sound continuous stop function (continuous sound stop function) for the first time when an acoustic device such as an emergency bell (district sound) really rings and wants to stop it. In the sound stop device configured as described above, even after the sound continuous stop function (continuous sound stop function) is set, if a predetermined condition newly occurs, the sound continuous stop function ( The continuous sound stop function) is canceled.

  FIG. 1 is a diagram showing a configuration example of a fire alarm facility according to the present invention. 1 has a fire receiver 1, district lines L1 to Ln extending from the fire receiver 1 to the respective districts A1 to An, and district sounds (district bells, acoustic bells) B1 to Bn. doing.

  Here, a fire detector 2 is connected to each of the district lines L1 to Ln. When a fire detection signal is output from a certain district line, for example, the fire detector 2 of L1, the fire detection signal is The fire receiver 1 is notified via the line L1.

  In addition, the fire receiver 1 includes a control unit 4 that controls the whole, a main acoustic unit 8, an operation unit 10, and a display unit 20.

There is provided a district acoustic continuous stop function ON holding unit (memory) 7 that holds the acoustic continuous stop function when it is ON.

  The operation unit 10 is, for example, an operation panel (a panel that can be operated from the front of the fire receiver 1 without operating the inside of the fire receiver 1). The operation unit 10 includes a main sound stop switch 11 and A district sound temporary stop switch 12, a recovery switch 13, and a fire input / fire determination switch 14 are provided.

  Note that the sound stopping device for fire alarm equipment in the present invention is actually realized by the fire receiver 1.

  In the fire alarm system shown in FIG. 1, the first form of the present invention is such that, for example, a fire detection signal as a false alarm is output from the district line L1, and the sound device (zone acoustic, for example, B1) really sounds. It is possible to set the sound continuous stop function (continuous sound stop function) for the first time when it is desired to stop the sound. Stop function) cannot be set), and even after the sound continuous stop function (continuous sound stop function) is set, a plurality of district lines L1 to Ln When a fire detection signal is output from a district line (for example, L1 and L2), the acoustic continuous stop function (continuous acoustic stop function) is immediately canceled. In this case, the ringing of the district sound B1 corresponding to the district line L1 is restored, and the district sound B2 corresponding to the district line L2 is further ringed.

  Further, in the fire alarm facility shown in FIG. 1, the second embodiment of the present invention is such that, for example, a fire detection signal as a false alarm is output from the district line L1, for example, and the acoustic device (district acoustic, for example, B1) rings. It is possible to set the continuous sound stop function (continuous sound stop function) for the first time when it is desired to stop this (ie continuous sound stop function in advance from normal (continuous sound stop function) A new district line (for example, L3) even after the sound continuous stop function (continuous sound stop function) is set. When a fire detection signal is output from the above, the acoustic continuous stop function (continuous acoustic stop function) is immediately canceled. In this case, the sound of the district sound B1 corresponding to the district line L1 is restored and the district sound B3 corresponding to the district line L3 is further sounded.

  In the first or second embodiment, the setting of the acoustic continuous stop function (continuous acoustic stop function) is performed by means (specifically, for example, the operation unit 10) disposed at a position where it can be operated immediately when necessary. The area sound temporary stop switch 12 is pressed by, for example, a predetermined time (for example, 3 seconds) or more). That is, for example, when the district sound temporary stop switch 12 is pressed for a certain time (for example, 3 seconds) or longer, the district sound control unit 5 of the control unit 4 causes the district sound continuous stop function ON holding unit (memory) 7 to It is held that the stop function is ON.

  Moreover, in the said 1st or 2nd form, the said sound continuous stop function (continuous sound stop function) is cancelled | released when the district sound temporary stop switch 12 of the operation part 10 is operated. It has become.

  Alternatively, the set sound continuous stop function (continuous sound stop function) is longer than the set time (for example, about 2 to 10 minutes) of the district sound pause by the district sound pause switch 12 (for example, several hours). ) Is canceled by the timer 6 so as to be canceled after a lapse of time.

  Alternatively, the set sound continuous stop function (continuous sound stop function) is canceled by operating the fire input / fire determination switch 14 or the recovery switch 13.

  Moreover, in the said 1st or 2nd form, when the acoustic continuous stop function (continuous acoustic stop function) is set, the acoustic continuous stop function (continuous acoustic stop function) is set. The state is displayed on the display unit 20.

  As described above, in the first embodiment, the sound continuous stop function (continuous sound stop function) can be set for the first time when the sound device really rings and it is desired to stop the sound device. Even if the sound continuous stop function (continuous sound stop function) is set, if a fire detection signal is output from multiple district lines, the sound continuous stop function (continuous Therefore, even if it becomes a situation where an alarm must be performed after a continuous acoustic stop, the alarm stop is prevented, and the alarm (sound of the district sound is released) by releasing the alarm stop. ) Can be recovered and an abnormality can be reported.

  In the second embodiment, the acoustic continuous stop function (continuous acoustic stop function) can be set for the first time when the sound device really rings and it is desired to stop it. And even after the sound continuous stop function (continuous sound stop function) is set, if a fire detection signal is output from a new district line, the sound continuous stop function (continuous sound Since the stop function) is released, the situation where the alarm must be stopped after a continuous acoustic stop is prevented to prevent the alarm from being stopped. It is restored and can report the abnormality.

  In the first or second embodiment, it is assumed that the sound continuous stop function (continuous sound stop function) is initially set when a predetermined condition is satisfied. When a fire detection signal is output from the line, the setting of the acoustic continuous stop function (continuous acoustic stop function) is prohibited.

  Next, the operation of the sound stopping device of the fire alarm facility according to the present invention, in practice, the operation of the fire receiver 1 will be described with reference to the flowchart of FIG.

  Referring to FIG. 2, when the district sound (for example, B1) rings (step S1), it is determined whether or not the district sound temporary stop switch 12 is pressed (step S2). When the district sound pause switch 12 is pressed, it is further determined whether or not the district sound pause switch 12 has been pushed for a predetermined time (for example, 3 seconds) (step S3). As a result, if the district sound pause switch 12 is pressed but not pressed for a certain period of time (for example, 3 seconds), the district sound suspension process (that is, the district sound is stopped for about 2 to 10 minutes, for example). (Step S12).

  On the other hand, when it is determined in step S3 that the district sound temporary stop switch 12 has been pressed for a predetermined time (for example, 3 seconds) or longer, the sound continuous stop function (continuous sound stop function) is turned ON (set). (Step S4). And it is displayed on the display part 20 that the acoustic continuous stop function (continuous acoustic stop function) is set (step S5).

  As described above, when the sound continuous stop function (continuous sound stop function) is set, the district sound is continuously stopped until the following predetermined condition is newly generated. In other words, even after the sound continuous stop function (continuous sound stop function) is set, if the following predetermined condition newly occurs, the sound continuous stop function (continuous sound stop function) is immediately generated. (Function) is released (the suspension of the district sound is released).

  That is, after the sound continuous stop function (continuous sound stop function) is set, it is determined whether or not a fire detection signal is input to the fire receiver 1 from a plurality of district lines (step S6). As a result, when fire detection signals are input to the fire receiver 1 from a plurality of district lines, the sound continuous stop function (continuous sound stop function) is turned off (released) (step S11).

  On the other hand, when a fire detection signal is not input to the fire receiver 1 from a plurality of district lines in step S6, it is determined whether or not a fire detection signal is input to the fire receiver 1 from a new district line. (Step S7). As a result, when a fire detection signal is input to the fire receiver 1 from a new district line, the acoustic continuous stop function (continuous acoustic stop function) is turned off (released) (step S11).

  On the other hand, when a fire detection signal is not input to the fire receiver 1 from the new district line in step S7, it is determined whether or not the district sound temporary stop switch 12 is pressed (step S8). As a result, when the district sound temporary stop switch 12 is pressed, the sound continuous stop function (continuous sound stop function) is turned off (released) (step S11).

  On the other hand, when the district sound temporary stop switch 12 is not pressed in step S8, it is determined whether or not there is an output from the timer 6 (step S9). As a result, when there is an output from the timer 6, the sound continuous stop function (continuous sound stop function) is turned off (released) (step S11).

  On the other hand, when there is no output from the timer 6 in step S9, it is determined whether or not the fire input / fire determination switch 14 or the recovery switch 13 is pressed (step S10). As a result, when the fire input / fire determination switch 14 or the recovery switch 13 is pressed, the sound continuous stop function (continuous sound stop function) is turned off (released) (step S11).

  On the other hand, when the fire input / fire determination switch 14 or the recovery switch 13 is not pressed in step S10, the process returns to step S4 again, and the processes of steps S4 to S10 are repeated.

  Thus, in the present invention, after the sound continuous stop function (continuous sound stop function) is set, the district sound is continuously stopped until a predetermined condition is newly generated. When a new condition occurs, the sound continuous stop function (continuous sound stop function) is immediately released (the stop of the district sound is released). As a result, the problem as in the sound stop device of Patent Document 1, that is, once set to the sound continuous stop function (continuous sound stop function), the sound continuous stop function (continuous sound) is set unless the receiver is reset. It is possible to solve the safety problem that the stop function) cannot be released and the sound is completely stopped.

  The present invention can be used for a fire alarm system and the like.
