BACKGROUND OF THE INVENTION
The present invention relates to an automatic fire alarm system that is configured to output a warning in conjunction with a district sound device when a fire detector or the like is activated.
[0002]
[Prior art]
Conventionally, automatic fire alarm systems have been introduced in buildings and condominiums, fire receivers have been installed in disaster prevention monitoring rooms, etc., and fires have occurred based on data such as smoke concentration and ambient temperature in each room and dwelling unit. Is monitoring.
When a fire detector is installed as a disaster prevention terminal in each room or floor, etc., the fire receiver notifies the occurrence of a fire by the district acoustic device set in advance corresponding to the fire detector. And people in the building (residents) can evacuate quickly. At the same time, smoke control equipment (such as fire doors and smoke vents) adjacent to the fire detector that has been reported is linked and controlled to prevent the spread of fire and smoke.
[0003]
Furthermore, the automatic fire alarm system is equipped with a stage alarm function, and once an alarm stop operation has been performed, if an abnormality such as a fire continues to be detected, an alarm is again issued. I am trying to output. In other words, when the fire detector issues a warning, the fire receiver outputs an alarm and activates the district sound device. In this state, the sound stop switch is operated, and the sound output at the fire receiver and the district sound device are operated. Even if the operation of the fire detector is stopped, it is left without performing on-site confirmation and recovery operations, and when the fire detector continues to fire for a predetermined time, an alarm is output again at the fire receiver. At the same time, the district audio system is activated to seek management from the manager.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned conventional automatic fire alarm system, the time until the alarm is output again by the stage alarm function is not known to the administrator, so that the administrator is confused when the alarm is output again. However, it was expected that quick responses could not be taken.
[0005]
The present invention has been made in view of such circumstances, and an automatic fire alarm system that enables an administrator or the like to reliably recognize that an alarm may be output again by a stage alarm function. The purpose is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the automatic fire alarm system according to claim 1 of the present invention, the fire receiver is provided with an informing means for informing a predetermined time until it automatically re-activates.
As a result, in the fire receiver, when an administrator etc. performs an acoustic stop operation, it can be seen that an alarm may be output again, and if the time until the alarm is output is known, In addition, it is understood that it is only necessary to take measures such as on-site confirmation and recovery operation.
[0007]
In Claim 2, in Claim 1, the alerting | reporting means of a fire receiver is continuously alert | reported during the said predetermined time, Comprising: While receiving the operation signal continuously from a disaster prevention terminal device It is characterized by that.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an example of the configuration of the main part of the automatic fire alarm system of the present invention.
The fire receiver 1 installed in the disaster prevention monitoring room or the manager's room is lowered by the multiple transmission line L in the fire detector S, gas leak alarm G, fire prevention water tank installed in each dwelling unit or floor, etc. Various alarm devices 3 that detect the above, smoke prevention devices 4 such as fire doors and dampers, and district acoustic devices B (district bells) are connected via respective repeaters 2a to 2e.
[0010]
In addition, although the case where the fire receiver 1 is a so-called R-type receiver in which a disaster prevention terminal such as the fire detector S is connected by a common multiplex transmission line L is shown here, the present invention is not limited thereto. Instead, it may be a so-called P-type receiver in which fire detectors installed in each monitoring area such as each floor are connected in parallel using a plurality of lines.
[0011]
The fire receiver 1 includes a CPU and the like, and includes a signal processing unit 10 that controls each unit in the fire receiver 1, an operation unit 11 that includes various operation switches, and a display unit that constitutes display means using a liquid crystal screen or the like. 12, a storage unit 13 constituted by a RAM, a transmission control unit 14 for controlling the multiplex transmission through the multiplex transmission line L, an acoustic output unit 15 for controlling the acoustic output from the speaker SP, and a predetermined time. And a timer unit 16 for measuring time.
[0012]
In the normal monitoring state, the fire receiver 1 performs polling through the multiplex transmission line L based on the address information of each disaster prevention terminal such as the fire detector S set in the address setting table 13b of the storage unit 13. In such a state, for example, one of the fire detectors S is notified and a fire signal (fire detector) is transmitted by an interrupt signal through the multiplex transmission line L. When the operation signal (S) is received, the operation is as follows.
[0013]
Upon receipt of the fire signal, the fire receiver 1 turns on or blinks an indicator lamp (display unit 12) indicating the operation of the fire detector S, and a district window (display unit) corresponding to the fire detector S installation location that has been reported. 12) is turned on or blinked, and the sound output unit 15 outputs an alarm sound from the speaker SP. Therefore, the illustrated sound output unit 15 and the speaker SP constitute a main sound device.
[0014]
At the same time, the fire receiver 1 refers to the interlocking table 13a of the storage unit 13 and sends an operation control signal to the district sound device B registered in advance corresponding to the fire detector S in the table 13a. The alarm is output from the district sound device B. Further, the smoke prevention device 4 is operated to form a smoke emission section. That is, when the fire receiver 1 confirms the occurrence of a fire, the fire control device 1 controls the district sound device B and the smoke-proof device 4 in conjunction with each other.
[0015]
In this state, if the sound stop switch sw1 of the operation unit 11 that is a sound stop operation means is operated, a stop control signal is sent to the district sound device B that is outputting a warning to stop the warning output.
After this operation, the administrator goes to confirm the site where the fire detector S is installed, and operates the recovery switch sw2 of the operation unit 11 when the report is incorrect. The fire receiver 1 is returned to the normal monitoring state, but when the fire signal is continuously received from the fire detector S for a predetermined time from the time when the acoustic stop switch sw1 is operated. In addition to requesting countermeasures from the manager or the like, an alarm is again output from the district acoustic device B in order to encourage the evacuation of the residents (step alarm function).
[0016]
In the present invention, when the acoustic stop switch sw <b> 1 is operated, it is notified that an alarm may be output again. That is, when the operation signal is continuously received from the disaster prevention terminal device such as the fire detector S for a predetermined time after the operation of the sound stop switch sw1, it is notified that the district sound device B is reactivated. As a result, when the administrator or the like knows the time until the alarm is output again when the sound stopping operation is performed in the fire receiver 1, the administrator can confirm the site or perform the recovery operation until then. I know it ’s good.
[0017]
The illustrated configuration includes an acoustic output unit 15 that also constitutes an audio output unit that outputs an audio message, and a display unit 12 that displays a visual message as means for performing the notification. That is, here, as the notification means, both a means for outputting a voice message and a means for displaying a visual message are provided, but only one of them may be provided. In addition, the sound output unit 15 is configured to be used as a main sound device and a sound output unit that outputs a voice message, but may be configured separately.
[0018]
For example, a voice message such as “I will re-sound in XX minutes later” can be output from the speaker SP, and a visual message can be, for example, “Re-sound in XX minutes later. Please operate the recovery switch, "characters and figures may be displayed on the display unit 12.
Note that the time for such notification is not limited to when the acoustic stop switch sw1 is operated. That is, during a predetermined time until the alarm output again, and while receiving the operation signal from the disaster prevention terminal, continuously notify or periodically notify Also good.
[0019]
For continuous notification, for example, “Voice will be sounded if recovery operation is not performed” is repeatedly output, or “Resound again in XX minutes. Please operate "and display a visual message, counting down the time until re-ringing.
In addition, when regularly informing, for example, a voice message such as “I will re-sound in XX minutes” is output every time the time until re-sound approaches in a predetermined unit (for example, every minute). Or a visual message such as “Resound again in XX minutes. Please operate the recovery switch after checking the site” is displayed in the same way as a voice message.
[0020]
Next, an example of the operation of the fire receiver 1 described above is shown in a flowchart (steps 100 to 114) in FIG.
Here, when a fire signal is received from the fire detector S as a disaster prevention terminal, the district acoustic device B (district bell) is operated, and the acoustic stop switch sw1 is operated, so that the display unit 12 The case where the re-ringing message as described above is displayed is shown.
[0021]
When a fire signal is received from the fire detector S (100), the main sound is output and the district bell B corresponding to the fire detector S is operated to sound an alarm sound (101, 102). In this state, when the sound stop switch sw1 is operated (103), after stopping the ringing of the district bell B (104), the timer unit 16 starts counting (timer start) (105) and displays a re-ringing message. (106). At this time, when the time until re-sounding is also displayed, the time until the timer expires is displayed first, and the time is displayed while counting down.
[0022]
The fire receiver 1 continues to receive a fire signal after starting the timer (107), and the recovery switch sw2 is not operated (108), and when a predetermined time has elapsed (time over) (109) ) Deletes the re-sound message (110) and re-sounds the district bell B (111). After this, if the acoustic stop switch sw1 is operated again, the operation of the district bell B can be stopped, and the operations after Step 103 are repeated.
[0023]
On the other hand, if the fire signal is not received before the time expires (107), it indicates that the fire detector S has recovered, so after canceling the timer, the re-sound message is deleted (112) and recovered. The operation of the switch sw2 is waited for. In addition, when the recovery switch sw2 is operated before the time is up, the timer is canceled, the re-ringing message is deleted (113), and the lit indicator lamp is turned off to perform system recovery. Return to the original monitoring state (114).
[0024]
【The invention's effect】
As can be understood from the above description, in the automatic fire alarm system according to claims 1 to 6 of the present invention, when the sound receiver is operated, the fire alarm is performed thereafter by the stage alarm function. Since it notifies that the district audio equipment may be reactivated, the administrator should take measures such as confirming the site where the disaster prevention terminal has been activated and performing recovery operations until the alarm is output again. It turns out that it is good, and there is no confusion when the alarm is output.
[0025]
In particular, in claim 2, since the notification is continuously performed after the sound stop operation is performed, the administrator outputs a warning again if the manager does not take an appropriate measure during the notification. I understand that
According to the third aspect, since the notification is periodically performed after the sound stop operation is performed, each time the notification is performed, the administrator may output an alarm again unless an appropriate countermeasure is taken. I understand.
[0026]
In claim 4, notification that the district sound device may be reactivated is performed by voice message output. In claim 5, the notification is performed by visual message display. In claim 6, the notification is performed by voice message. Since both output and visual message display are used, the contents of the message are easy to understand for the administrator.
