Description

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

[Background technology] When a warning is issued in the Jubei Self-Defense Warning System, the district bell rings, and the district bells in the district where the warning was issued and the districts directly above it ring to issue an evacuation warning. However, if the manager goes to the scene of the alarm and confirms that it is not a fire,
Since the district did not have a means to disable the ringing of the district bell, it was necessary to return to the receiver and disable the ringing. In this case, before investigating the non-fire cause, the manager had to rush back to the receiver location to prevent panic among those who heard the ringing of the district bell. *If the district bell was turned off at the receiver side as a countermeasure against octopuses, it had the fatal drawback of not being able to alert you in the event of an actual fire.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned problems, and its purpose is to quickly stop the ringing of the district bell using a repeater at the confirmed location when a non-fire is confirmed; The objective is to provide a self-fire alarm system that can prevent a panic situation from occurring.

[Disclosure 1 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; A repeater that detects alarms from general sensors and exchanges information with addressable sensors through multiplex transmission is installed at a designated location in the building, and each repeater is equipped with at least a corresponding repeater. In a self-fire alarm system connected to a district bell that rings when there is a fire alarm, each repeater is equipped with a non-fire switch that is turned on in the event of a non-fire. It is characterized by being installed in a place where it is difficult to operate, such as inside.

The present invention will be explained below with reference to Examples. Figure 1 shows the overall configuration of the self-fire alarm system using this embodiment. It is connected via a telephone line 3 and a telephone line 4 for an intercom. The repeater 2 is connected to a sensor line 5, a smoke prevention equipment control line 6, and a district bell control line 7. The sensor line 5 has a general sensor 8 that changes the line signal level of the sensor line #15 when it detects that the level of fire-generating elements such as smoke or heat has exceeded a certain level, and a separate address. In addition, it is connected to a sensor 9 with an address which, like the general sensor 8, issues alarms by changing the line signal level and also transmits alarm information by multiplex transmission, and also connects to a sensor 9 with an address, which transmits alarm information by changing the line signal level, and also with a general transmitter or a transmitter with an address 8! 11 are connected.

A display sending switch SW is provided to send the display.

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 8!1 sequentially calls each repeater 2 by multiplex transmission, and exchanges information between the receiver 1 and the called repeater 2, and the repeater 2 checks the signal level of each sensor line 5. In addition to monitoring, the addressable sensors 9 are sequentially called by multiplex transmission to exchange information.

At this moment, when the signal level of the sensor line 5 changes and an alarm is detected, the repeater 2 first interrupts polling 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. And when line interlocking is set, the corresponding smoke prevention equipment 13
Outputs a control signal to operate. In addition, the 70 asterisk signal buzzer 35 provided in the repeater 2 is made to sound.

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 receiver 1, the representative display section 16 displays the fire display and the presence or absence of interlocking based on the returned information.
At the same time, the location of the alarm is displayed on the district display section 15. Also, when it is detected that interlocking is set, the receiving file indexes the interlocking table (other than the alarm repeater),
A smoke prevention and exhaust control command interlocking between repeaters is transmitted to the target repeater 2 by multiplex transmission, and a control command to sound the floor station buzzer 35 is transmitted to the repeaters 2 other than the repeater 2 by multiplex transmission, and A control command for ringing the district bell 12 is transmitted to the repeater 2 on the floor immediately above the alarm location by multiplex transmission. When a fire alarm is confirmed and the fire determination switch SW2 is turned on, the main bell 14 will ring, and if the district bell 12 stops ringing and the smoke prevention interlocking stop is activated, a signal will be sent to forcibly cancel it. It is transmitted to each repeater 2 by multiplex transmission.

Or a general transmitter or one with an address! When a fill alarm is issued, the alarm area display section 17 displays a processing operation similar to that for a sensor alarm.

By the way, when there is an alarm, the administrator goes to the location displayed on the district display section 15 to check whether the alarm is due to an actual fire or a non-fire.
If it is confirmed that the alarm was caused by a non-fire at the scene, the manager presses the door button 43 of the nearest repeater 2 to unlock the door 42, opens the door 42, and turns on the non-fire switch SW6 provided inside. It is recommended to operate. Easy non-fire switch SW by unlocking by operating i%42 and door button 42
6 is prevented from being performed. By the way, as shown in FIG. 4, in the repeater 2, when an alarm is issued, the district bell 12 is rung and alarm information is sent, and the receiver 1 controls the district bell 12 to ring to the repeater 2 on the floor directly above. The command is sent by multiplex transmission, and a check is made to see if the non-fire switch SW6 is operated.
It is now checking to see if there is an order from the side to stop the ringing. However, because the joint fire switch SW6 was turned off, it caused the fire of the pond V bell 12 to be stopped, and the operation information was sent to the receiver 1, and by multiplex transmission from the receiver 1, it was The ringing of district bell 12 will also be stopped. Then, while maintaining this stoppage, a state is entered in which it is checked whether or not there is a fire alarm within the relay device 2, or whether a non-fire release command is received from the receiver 1 side. The non-fire cancellation command from the receiver 1i side is provided to prioritize the information from the receiver 1 side and ensure safety.For example, when a warning is issued from the repeater 2, etc. on the floor directly below the floor in question. It is transmitted in such cases. When the above-mentioned non-fire cancellation command is received or an alarm is issued within the same repeater 2 while the ringing is stopped, the repeater 2 immediately cancels the ringing stopped state and rings the district bell 12.

In the receiver 1, by receiving operation information of the non-fire switch SW6, a command to stop ringing the district bell 12 is displayed on the operation/display unit 10, which can be confirmed on the receiver 8!1 side. Also, when operating the non-fire switch SW, district bell 12! Only the @ operation is stopped, and the system is restored on the receiving side.

[Effect of the invention 1] In the self-fire alarm system configured as described above, the present invention provides a non-fire switch in each repeater that stops the ringing of the corresponding district bell when it is turned on when a non-fire is confirmed. Because of this system, if a manager confirms that there is a non-fire at the scene, he can stop the ringing of the district bell by operating the non-fire switch on the repeater at the scene without having to return to the receiver side, thereby preventing panic. This allows for quick non-fire measures to be taken before a fire alarm occurs, and since the non-fire switch is installed in a location where it is difficult to operate, such as inside a repeater, it can be easily operated and cause the alarm to stop ringing incorrectly. This has the effect of being able to prevent this from happening.
