Description

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

[Background technology] When an alarm is issued in a conventional fire alarm system, the manager rushes to the scene of the alarm with a plug-in telephone, plugs the telephone into the telephone jack of a transmitter installed near the scene, and receives the signal. I was talking to the machine. In this case, the receiver side detects that the phone is plugged into the jack and sounds a buzzer to notify the receiver operator. They pick it up and talk to the manager at the site.

By the way, with this type of communication system, not only do you have to carry a telephone with you to the site, but the person who goes to the site also has to search for the transmitter, and the receiver has no idea where the call is being made. It was necessary to check each location from the other party, and it was impossible to process multiple locations.

[Purpose of the Invention] The present invention was made in view of the above-mentioned problems, and its purpose is to facilitate communication between the receiver side and the site, and to provide a safe and secure way to act in the event of an emergency. The purpose is to provide a self-fire alarm system that can respond reliably.

[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; Fire alarm systems that detect alarms from general detectors and exchange information with addressable detectors through multiplex transmission are installed at designated locations in buildings, and are received via telephone lines. Each repeater is equipped with an intercom that is connected to the repeater, a call button that allows the intercom to communicate with the receiver, and a call-in-progress light that indicates that the receiver or other device is communicating with the intercom of the repeater. , the receiver has another intercom, a call light that indicates that there is a call when there is a call from a repeater, a display that displays the installation location of the repeater that made the call, and a display that indicates when the call is in progress.

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 information is exchanged between the receiver 1 and the called repeater 2, and the repeater 2 changes the signal level of each sensor line 5. Along with monitoring, the addressable sensors 9 are sequentially called by multiplex transmission to exchange information.

When the signal level of the sensor line 5 changes and an alarm is detected, the repeater 2 first interrupts the boring by multiplex transmission with the receiver 1.
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. When line interlocking is set, a control signal for operating the corresponding smoke prevention equipment 13 is output. Also, the floor station buzzer 35 provided in the repeater 2 is made to sound.

On the other hand, on the receiver 1 side, the address of the repeater 2 that made the interrupt request is indexed and the repeater 2 of that address is
call. The called repeater 2 returns information such as the alarm line number and the address of the alarm sensor, as well as interlock operation information if there is an interlock setting. In the receiver 1, based on the returned information, the representative display section 16 displays the fire indication and whether or not there is an interlock, and the district display section 15 displays the location where the alarm was issued. In addition, when detecting that interlocking is set, receiver 1 indexes the interlocking table (other than alarm repeaters) and transmits a smoke prevention and exhaust control command for interlocking between repeaters to 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 multiplexed to the repeater 2 on the floor immediately above the alarm point. Transmit by transmission. When a fire alarm is confirmed and the fire determination switch SW ₂ is turned on, the main bell 14 will ring, and if the ringing of the district bell 12 is stopped or the smoke prevention interlocking stop is activated, this signal will be forcibly canceled. is transmitted to each repeater 2 by multiplex transmission.

In addition, when a general transmitter or a transmitter with an address 11 generates an alarm, processing operations similar to those for a sensor alarm are performed, and the receiver 1 side displays a fire display and the location of the alarm on the alarm area display section 17. indicate.

By the way, if an alarm occurs and the manager wants to go to the alarm site and talk to the person on the receiver 1 side, first press the call button 3 on the intercom 37 of the repeater 2 on the floor concerned.
It is best to put in 8. In other words, when the call button 38 is turned on, the receiver 1 receives a return signal through multiplex transmission.
The ON information of the call button 38 is transmitted to the call button 38. When the receiver 1 receives this information, it lights up the call light 26 and displays the building number and floor number from the address of the repeater 2 on the display unit 24. When the person monitoring the receiver 1 sees this display and turns on the call switch SW ₃ , the receiver 1 switches on the call light 26.
is turned on and the call light 25 is turned off. Also, the repeater 2 is called by multiplex transmission to transmit a line connection command. The repeater 2 that receives this transmission signal connects the telephone line 4 to the intercom 37, connects the intercom 37 to the intercom 22 of the receiver 1, and sets it to enable communication.

Now, when the call is finished, it is sufficient to turn off the call switch SW ₃ on the receiver 1 side, and in this case, the call light 26 of the receiver 1 is turned off and the display on the display section 24 is turned off. Then, a line release command for disconnecting the communication line 4 is transmitted to the repeater 2 by multiplex transmission. Then, in the repeater 2 that received the line release command, the intercom 37
is disconnected from the telephone line 4.

By the way, during the above-mentioned call, when the call button 38 of another repeater 2 is pressed and the receiver 1 receives the ON information of the call button 38, the receiver 1 lights up the call light 25 and accepts the call. The command to turn on during a call is transmitted to the repeater 2 through multiplex transmission. Then, in the repeater 2, the call light 39 is turned on to indicate that the call is in progress. If the call has ended, the call light 39 is turned off, and the new building and floor number are displayed on the display section 24. The supervisor also sends the display on the display section 24 using the forwarding switch SW ₄ to display the building and floor number of the repeater 2 that made the call and to set it to enable communication. Then, when the supervisor turns on the call switch SW ₃ , the receiver 1 transmits a line release command to the repeater 2 that is in the middle of a call by multiplex transmission, and transmits a line connection command to the repeater 2 that made the call by multiplex transmission. do. Then, the intercom 37 of the repeater 2, which was in the middle of a call, was disconnected from the call line 4, and
The interphone 37 of the called repeater 2 will be connected. FIG. 4 and FIG. 5 show operational flowcharts in the above-mentioned intercom call.

In this embodiment, when calls from the repeater 2 overlap on the receiver 1, the order of display on the display unit 24 is the repeater 2 that issued the alarm, the repeater that was previously on a call and has been pressed. 2. Priority display is performed in the order of repeaters 2 that press the call button 38 first.

[Effects of the Invention] The present invention provides a self-fire alarm system configured as described above, including: an intercom connected to a receiver via a telephone line; a call button for communicating with the receiver via the intercom; Since each repeater is equipped with a call light that indicates that a call is in progress with the intercom of the repeater, there is no need for the manager to carry the telephone each time he or she rushes to the scene of the alarm. There is no need to search for the transmitter at the scene, and there is an effect that you can safely and reliably respond to emergencies. A call light that displays, a display that displays the installation location of the repeater that made the call, a call light that indicates that a call is in progress, and a call from another repeater other than the repeater that is currently calling. a forwarding switch for switching the display content on the display section to the installation location of another repeater, and a call switch for setting a call line connection to the repeater whose installation location is displayed on the display section, When receiving operation information sent by multiplex transmission by operating the call button on the device, the call light will be turned on, and if a call is not in progress with another repeater, the location of the repeater will be displayed on the display. When the call switch is operated, a line connection command to connect the intercom call line to the repeater is sent via multiplex transmission, and the call light is turned on and the call light is turned off. , and also sends a line connection command to connect the intercom call line to the relevant repeater by operating the call switch via multiplex transmission, and opens the line to disconnect the intercom call line to the repeater that was currently talking. Since the receiver is equipped with a control function that sends commands by multiplex transmission, you can operate the call by simply pressing the call button on the repeater side, so there are no mistakes in operation, and you can make a call even while the call is in progress. In addition, since you can control calls by simply operating the call switch and forward switch on the receiver side, the receiver side operations are easy, allowing you to respond safely and reliably in emergencies.Also, when a call is in progress, all you have to do is look at the display. It can be understood by
