Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a so-called R-type smoke prevention integrated self-fire alarm system.

[Background Art J] When a conventional fire alarm system is activated, the district bell and main bell are rung to issue an evacuation warning, but the notifications by these bells are not intended for the general public. Yes, but it was not aimed at people in management.

Since the district bell only rings on the alarm level and the floor directly above it, people outside of these areas cannot hear it, and if the person in charge is in the building away from the receiver, the alarm will ring. There were times when I didn't know the news. And this district bell is usually kept loud to give an alarm.
For example, if the sound was made to sound on all floors, there was a risk of panic.

[Purpose of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to sound a 70-a-day alarm at the time of an alarm, so that no matter where the manager is located in the building, To provide a self-fire alarm system capable of notifying the alarm and stopping the ringing of a floor station buzzer at a place where a repeater is installed so as not to cause panic after the alarm is confirmed.

[Disclosure of the Invention] The present invention provides a sensor with an address that is connected to a receiver via a signal transmission line, exchanges information with the receiver through multiplex transmission, and is connected via a sensor line; In a self-fire alarm system in which repeaters are installed at predetermined locations in buildings, each repeater is installed on the floor. A stage 1 buzzer and a release switch for canceling the ringing of the floor station buzzer are provided, and when alarm information is received from any of the repeaters, a ringing control command to ring the floor station buzzer is multiplex transmitted to each repeater. The receiver is characterized by having a function of transmitting, by multiplex transmission, a ringing cancellation command for stopping the ringing of the floor station buzzer to each repeater when the operation information of the cancellation switch is received from any of the repeaters. It is something.

, and are provided.

The intercom 37 is equipped with a call button 38 and a call light 39.

Next, the operation of this self-fire alarm system in the alarm processing will be explained.

First, the receiver 1 sequentially calls each repeater 2 by multiplex transmission, and the receiver 1 and the called repeater 2 open and exchange information. Along with monitoring, the addressable sensors 9 are sequentially called by multiplex transmission to exchange information.

At this point, when the signal level of sensor #15 changes and an alarm is detected, the repeater 2 first interrupts polling by multiplex transmission with the receiving PIil.

Then, the number of the sensor line 5 that issued the alarm and if the sensor is a sensor 9 with an address, the address of the sensor is stored. The repeater 2 displays the occurrence of a fire on the representative indicator light 27, displays the building, floor number, and district number of the corresponding building from the alarm line in numbers on the district display section 28, and at the same time sends a control signal to ring the district bell 12. occurs. And when line interlocking is set, the corresponding smoke prevention equipment 13
Outputs a control signal to operate. Also, the floor station buzzer 35 provided at relay n2 is sounded.

On the other hand, on the reception side 1 side, the address of the repeater 2 that made the interrupt request is indexed and the repeater 2 at that address is called. The called repeater 2 returns information such as the number of the alarm line and the address of the alarm sensor, as well as interlock operation information if there is an interlock setting. In the receiving PIi1, based on the returned information, the representative display section 16 displays the fire indication and the presence or absence of interlocking, and the district display section 15 displays the location where the alarm was issued. In addition, when detecting that interlocking is set, the receiver 8!1 indexes the interlocking table (other than the alarm repeater) and transmits the inter-repeater interlocking smoke prevention and exhaust control command to the target repeater 2 by multiplex transmission. At the same time, a control command to ring the floor station buzzer 35 is transmitted to repeaters 2 other than the relevant repeater 2 by multiplex transmission, and a control command to ring the district bell 12 is transmitted to the repeater 2 on the floor immediately above the alarm point. Transmit using multiplex transmission. When a fire alarm is confirmed, the fire determination switch SW is installed to ring the central bell 14, stop the ringing of the district bell 12, and forcibly cancel the smoke prevention interlocking stop if it is activated. The signal is transmitted to each repeater 2 by multiplex transmission.

Also, when a general transmitter or a transmitter with address 11 issues an alarm, processing operations similar to those for a sensor alarm are performed, and the reception lf! On the i side, the location where the alarm occurred is displayed on the alarm area display section 17 along with the fire display.

By the way, there was an alert, so I went 1I away from the incoming file.
If you are located in taIIJ and hear the ringing of the floor station buzzer 35 of the nearest repeater 2, the administrator should immediately turn on the release switch S provided on the repeater 2.
By turning on W7, it is possible to stop the floor station buzzer 35 from ringing. That is, when the release switch SW is pressed, an interrupt request is issued from the repeater 2, and operation information of the release switch SW is sent to the receiver 1 by multiplex transmission. Upon receiving this information, the receiver 1 sequentially calls each repeater 2 and transmits a ringing release command to stop and release the ringing of the 70 station buzzer 35 installed in each repeater 35 by multiplex transmission. This causes the buzzer 35 to stop ringing. In this way, the floor station buzzer 35 has a low sound volume, and since the above-mentioned ringing can be stopped, it is possible to prevent panic from occurring. After confirming the alarm, the manager returns to the location of the receiver 1, or uses the intercom 37 of the repeater 2 to talk to the person on the receiver 1 side, and performs appropriate processing. FIG. 4 shows a 70-chart of the operations described above.

[Effect of the invention J] The present invention provides a self-fire alarm system constructed as described above, in which each repeater is provided with a floor station buzzer and a release switch for canceling the ringing of the floor station buzzer, When alarm information is received, a ringing control command is sent to each repeater to sound a 70-state buzzer via multiplex transmission, and when release switch operation information is received from any repeater, a 70-state alarm buzzer is sent to each repeater. Send a ring cancellation command to stop the buzzer of the assistant buzzer by multiplex transmission 8! Since the receiver is equipped with a function, when an alarm occurs, the floor station buzzer installed in the repeater will sound, ensuring that the manager will be notified of the alarm no matter where the manager is. It has become possible to reduce the number of managers, and it has also been possible to stop all 70 asterisk lamp buzzers from any repeater, causing panic among people who hear the sound of the 70 asterisk lamp buzzers. This has the effect of being able to stop the ringing immediately after waking up.
