Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field 1 The present invention relates to an adjacent area indicating/sounding system for fire alarms and the like.

[Background technology] Conventionally, when a fire breaks out in the same large building where multiple fire receivers exist, the fire receivers in that section operate to ring the district bell and turn on indicator lights, but The fire alarm δ is not activated in the area, and the area bell does not ring *Vt.

For this reason, after mutual communication and confirmation via intercom, etc., the ringing of the district bell of the adjacent block is called rJ! h¥? Methods such as hitting the ball are used. However, when a fire actually occurs, the people who are supposed to make contact and check often run away, so it is unclear whether they will be able to actually contact or check.
The problem was that it was difficult to avoid danger.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned points, and its purpose is to raise the sound of an alarm to neighboring areas and to control the display of indicator lights in the event of a fire, etc. An object of the present invention is to provide an adjacent area display and sound system that can quickly carry out fire extinguishing, evacuation activities, and a firefighting support system for adjacent areas.

[Disclosure of the Invention J (Embodiment) FIGS. 1 to 3 are diagrams showing an embodiment of the present invention,
This embodiment is an adjacent area warning sound system that detects fires, etc. in areas divided into a plurality of areas and displays an alarm. It is equipped with a fire receiver 1 that displays an alarm such as, and a timer 3 that performs a timed operation for a predetermined time from the time when a detection signal is received by the fire receiver 1.
For example, an adjacent area display panel 2 transmits a detection signal such as a fire that occurred in area A) to other adjacent areas (area B and area C), and a fire receiver M 1 receives the detection signal and sends the detection signal to the area, for example. A fire determination switch 4 which, when operated, sounds an alarm on the adjacent area display panel 2 of other areas B and C when there is an actual fire, is arranged in each area A to C.

Hereinafter, the operation will be explained according to the chart 70 in FIG. 1 and the specific circuit of the main part in FIG. First, when a fire breaks out in a certain area (for example, area A), the fire is detected by a sensor (not shown) installed in that area. The detection signal of this detector is received by the fire receiver 8!1 of the area A, and the fire receiver M8!1 is equipped with a district light indicating the area where the fire is occurring and a fire alarm, which is not shown in the figure. At the same time, the fire light that indicates that the main sound switch and the district sound switch are located in the local position is turned on, and the main sound such as a buzzer that emits an alarm sound and the district sound sound. When the main sound switch and the district sound switch are turned off so that the alarm sound does not sound, the switch warning light flashes to indicate this state. At this time, the administrator etc. determines whether or not there is an actual fire. If it is not a fire, the fire recovery switch S of the fire receiver 1 is operated to restore the fire receiver 1 and the adjacent area display panel 2 is activated. Recover. On the other hand, if it is confirmed that there is an actual fire, fire extinguishing activities are started, and the fire determination switch S4
Operate relay Ry3 and close contact r.

By closing, the detection signal is sent to the adjacent area display boards 2 of other areas B and C. In addition, when there is a real fire, the recovery switch S is not operated and the l! When the time-limited operation of the timer 3 of the J-contact area display panel 2 is completed, the relay Ry operates to close the contact R, and the closing of the contact r causes the fire determination switch S4 to be activated as described above. Relay RVs operates and contact r closes, thereby sending a detection signal to IJ & contact area display panel 2 of adjacent areas B and C.

In the above explanation, the circuit in Figure 2 was explained as area A, but from now on, the circuit in Figure 2 is referred to as area B or area C.
It will be explained as follows. Now, the contact point r3 of the adjacent area display panel 2 of area A (inside the lower two alpha chain lines in the figure) is closed. By closing this contact r, the district light 7 indicating which area the fire is occurring lights up, and the main sound switch S
If 1 is the localization, the tonic Il! F5 beeps. At this time, relay Ry operates and closes contact r41rs. This contact point r4 is used to shift the broadcast, and audio instructions for extinguishing a fire or evacuation are given, and people in other areas B and C support firefighting operations. This is to provide a fire detection signal to areas other than adjacent areas B and C. In addition, when the contact r2 is closed, the relay RFZ also operates, and the district sound 6 is sounded by closing the contact r2.In addition, when the district sound 6 and the main sound 5 are turned off, the switch The warning light LD is turned off.As described above, according to this embodiment,
When a fire or the like is detected by the fire receiver 1 in a certain area A, the signal is transmitted from the adjacent area display board 2 of that area A to the fire receiver 1 of the other area via the adjacent area display boards 2 of other areas B and C. It is possible to receive a detection signal indicating a fire, etc., thereby preventing a delay in responding to a fire, etc. in areas other than the fire outbreak area A, and preventing delays in rescue work. Equipped with timer 3 (i), fire detection (i)
Since it does not operate immediately when the detection 4g signal is input from ffil, false alarms etc. are sent to other areas B.

It is possible to reduce the danger of fire
, the adjacent area display g12 can be quickly moved 4g in the event of an actual fire, making it possible to quickly respond to the fire.

[Effects of the Invention 1] As described above, the present invention includes a man-made disaster receiver that displays an alarm for fire, etc. in the 0 zone, and a timer that operates for a predetermined time from when a detection signal is received by the fire receiver. an adjacent area display panel that transmits a detection signal of a fire, etc. that has occurred in the own area to an adjacent area after the timer expires;
Each area is equipped with a fire determination switch that sounds an alarm on the adjacent area display panel when operated when a detection signal is received by the fire receiver and there is an actual fire. When a fire, etc. is detected by a fire receiver, a detection signal indicating a fire, etc. can be transmitted from the adjacent area display board of the area to the fire receiver of the local area via the adjacent area display board of the local area. Therefore, it is possible to prevent delays in response to fires in areas other than the area where the fire occurred, and delays in rescue work.Furthermore, the adjacent area display board is equipped with a timer, and the detection signal from the fire receiver can be detected. Since it does not operate immediately when an input is received, the risk of issuing false alarms to the area can be reduced, and since it is equipped with a fire determination switch, it can quickly confirm the credit of the adjacent area display panel 2 in the case of an actual fire. This has the effect of making it possible to slow down the action and quickly respond to a fire.
