DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apartment house or the like in which a fire detector and a repeater are provided for each monitoring section such as a dwelling unit for individual monitoring, and a fire receiver is provided in a central management room or the like for centralized monitoring. Fire alarm system.

[0002]

2. Description of the Related Art As a conventional fire alarm system for an apartment house, for example, the one shown in FIG. 7 is known. The fire alarm system includes a fire detector 101, a repeater 102, and a receiver 1 for a dwelling unit which also serves as a base unit for an intercom.
03, an outdoor display 104 also serving as a door phone is provided, and a living building receiver 106 and an emergency power supply device 107 are provided on the management room side. Further, a speaker 110 and, if necessary, a smoke detector 111 are installed in a common part of each floor.

A fire detector 101 in a dwelling unit is a repeater 102
Is connected to the receiver 103 for dwelling units through the computer and monitors the fire. An outdoor indicator 104 is connected to the dwelling unit receiver 103 and normally functions as an intercom.

[0004] When the dwelling unit receiver 103 detects the operation of the fire detector 101, it issues a voice alarm and outputs a detector operation message. If the sound stop operation is not performed, the dwelling unit receiver 103 sends a fire confirmation signal to the dwelling unit receiver 106 after a lapse of a predetermined time (2 to 5 minutes) by the timer. At the same time, the audio alert turns into a fire message.

On the other hand, the fire detector 101
Is restored and the dwell unit receiver 103 performs a sound stop operation, the dwell unit receiver 103 is restored, and the dwelling unit receiver 106
Also does not send a fire confirmation signal to

[0006] Upon receiving the fire determination signal, the living building receiver 106 displays a fire alarm and transmits an interlocking signal to the dwelling unit receiver 103 in a neighboring dwelling unit on the fire floor and the floor immediately above.

[0007] The dwelling unit receiver 103 that has received the interlocking signal,
A common neighborhood fire message, such as "Fire. Fire. A fire has occurred in this neighborhood. Please confirm your safety and evacuate." At the same time, a nearby fire message is output by sending a voice signal from the living building receiver 106 to the speaker 110 in the common part of the fire floor and the floor immediately above.

Here, a receiver 103 for dwelling units provided in dwelling units
Is operated by receiving AC100V power supply from the dwelling unit. However, if the dwelling unit is turned off because the dwelling unit is vacant, the fire cannot be monitored at all. The emergency power supply unit 107 is installed in the room, and when AC100V of the dwelling unit is cut off, 24V DC is supplied from the emergency power supply unit 107 to be able to back up.

[0009]

However, in such a conventional fire alarm system, the intercom master unit of the dwelling unit is used as a dwelling unit receiver and the intercom is used as an outdoor display. There was a problem.

[0010] In recent years, an intercom master unit with a television monitor that displays an image of a television camera when a call is made from a collective entrance machine has become widespread. For this reason, the receiver for dwelling units must be incorporated in the intercom master unit compatible with the television monitor, and there is a problem in that development and manufacturing for it take time and cost.

In addition, while the fire alarm system does not basically require any equipment change once it is installed, the intercom equipment has a relatively short transition period to a new model, and cannot be used as a fire alarm system device. Is not always a good idea.

[0012] Further, the dwelling unit receiver functioning as an intercom master unit operates at AC100V of each dwelling unit. However, it is necessary to install an emergency power supply device to back up the power supply to AC100V in an unoccupied dwelling unit or the like. There is also a problem that the equipment cost is high.

[0013] The neighborhood message output by the sound source provided in the dwelling unit receiver 103 is "... fire. A fire has occurred in this neighborhood ....". There has been a demand for a system that can output a sound specifying a fire occurrence location.

[0014] The present invention has been made in view of such a conventional problem, and is not affected by the intercom equipment by separating it from the intercom equipment in the dwelling unit.
It is an object of the present invention to provide a fire alarm system capable of performing stable fire monitoring over a long period of time and further reducing equipment costs.

It is another object of the present invention to provide a fire alarm system capable of outputting a sound specifying a fire occurrence location as a fire alarm message to neighboring dwelling units.

A transmission control unit that receives data from the repeater and sends a command to the repeater, and controls sound output to the source repeater when a sensor activation signal is received from the repeater. And a receiver control unit that transmits a voice output control command to a repeater in a predetermined neighboring area when a command is transmitted and a fire determination signal is received from the repeater, and when a sensor operation signal is received from the repeater. And a voice message transmitting unit for transmitting a voice signal of a confirmation message to the voice signal line and transmitting a voice signal of a fire alarm message to the voice signal line when a fire determination signal is received from the repeater. .

As described above, since the present invention adopts an equipment configuration separated from the intercom equipment installed in each dwelling unit of the apartment house, the present invention is not limited to the installation and use of the intercom equipment and has a high reliability. High fire monitoring is possible.
Also, since there is no need to take power from the dwelling unit side, an emergency power supply device for backup can be eliminated. Further, from the viewpoint of the intercom equipment, it can be easily replaced by changing the model without being restricted by the fire alarm system.

Further, the connection of a speaker installed in a section such as a dwelling unit to an audio signal line from a fire receiver can be controlled by an audio output control command for a repeater.
The voice signal of various voice messages can be switched and transmitted from the fire receiver and output from the corresponding speaker.

Here, the relay controller of the repeater, when receiving the alarm signal from the fire detector, transmits the detector activation signal to the fire receiver and starts the accumulation operation, and performs the predetermined accumulation operation. If it is determined that a fire has occurred, a fire confirmation signal is transmitted to the fire receiver. In response to this, the receiver control unit of the fire receiver transmits a voice output control command to the transmission source repeater when receiving the sensor operation signal from the relay,
When a fire determination signal is received from the repeater, a voice output control command is transmitted to at least the same floor and another repeater installed immediately above the section where the transmitter repeater is installed, and the fire receiver The voice message output unit sends a confirmation message voice signal to the voice signal line when receiving the sensor operation signal from the repeater, and sends a fire alarm message to the voice signal line when the fire determination signal is received from the repeater. Is transmitted.

Therefore, when the fire detector issues a warning and a confirmation message is issued, the resident can confirm the fire and operate the push button switch to immediately send a fire confirmation signal to the receiver and respond accordingly. it can. Of course, even if the push button switch is directly operated without waiting for the alarm from the sensor, the fire determination signal can be immediately transmitted to the receiver.

The voice message transmitting section of the fire receiver transmits a voice signal having a content specifying the fire occurrence section as a voice signal of the fire alarm message. Since a repeater assigned a unique address for each unit such as dwelling units is installed, the fire receiver that received the fire confirmation signal
Because the fire occurrence section can be specified, for example, for the neighboring dwelling units on the fire occurrence floor and the immediately above floor, the detailed contents of specifying the fire occurrence place "... fire occurred in room XX floor XX ..." Can be issued by an audio signal from the fire receiver.

Further, a fire detector with a remote test function is provided as a fire detector, and a switching circuit for switching the detector line to the external tester when an external tester is connected to the repeater is provided. When receiving the alarm signal by the test normal end signal output from the external tester, the repeater control unit transmits a fire determination signal to the fire receiver to notify a test result. For this reason, the fire detector can be tested from the outside of the dwelling unit without entering the compartment such as the dwelling unit where the fire detector is installed.

The fire alarm system according to the present invention further includes a speaker repeater for controlling the output of a sound signal to the speaker, and the speaker repeater is connected to a transmission line and a sound signal line from the fire receiver.

The speaker repeater includes a transmission control unit for receiving a command from a fire receiver using a pre-assigned address, and a speaker for receiving a sound output control command from the receiver. And a repeater control unit for connecting a voice signal line from the device to output a voice message. The speaker repeater is connected to a speaker installed in a common part of an apartment house.

It should be noted that even if the push-button switch 6 is turned on in the alarm reception check routine in step S1,
The process immediately proceeds to the transmission of the fire determination signal to the receiver in step S9, but this point is omitted in the flowchart.

FIG. 6 is a flowchart of the receiver processing in the fire receiver 10 of FIG. In step S1, the fire receiver 10 checks the reception of the signal during accumulation indicating the sensor operation signal from the repeater. When the signal indicating that the signal is being stored is received, the repeater that transmitted the signal indicating that the signal is being stored is identified, and in step S2, the speaker of the sensor alarming dwelling unit is sounded to output a confirmation message.

That is, a voice output control command is transmitted to the repeater of the dwelling unit, and a voice signal of a confirmation message is transmitted in synchronization with the voice output control command. Subsequently, it is checked in step S3 whether or not a recovery signal has been received from the repeater. If the recovery signal has received a stop, the output of a confirmation message is stopped in step S8.

On the other hand, if the recovery signal has not been received, the reception of the fire determination signal is checked in step S4. When the fire determination signal is received in step S4, the repeater that transmitted the fire determination signal is specified from the address, and in step S5, the fire display and the fire are performed using the display unit 27 and the speaker 31 of the fire receiver 10.

The data collection command may be transmitted in a so-called polling manner by sequentially specifying the repeater address, or an interrupt signal may be transmitted from the repeater in which the detector has been activated or the fire has been determined to the fire receiver 10, In response to this interrupt signal, the fire receiver 10 performs a search for a repeater that caused an interrupt, specifies the repeater, and exchanges various commands and data necessary for a fire alarm with the specified repeater. May be performed by a method.

Further, when the disconnection of the sensor line 2 is detected by the disconnection detecting circuit 22 of the repeater 1 shown in FIG. 2, the repeater control unit 16 sends a disconnection detection signal to the fire receiver 10 and outputs the signal to the display unit 2.
At 7, a failure display such as a broken dwelling unit at the installation unit of the repeater, for example, “disconnection at room xx floor xx” is performed.

Next, the operation of the addressable fire detector 15 will be described. The storage operation processing of the addressable fire detector 15 is performed by the fire receiver 10. For example, if the addressable fire detector 15 is of the analog type, the fire receiver 10 monitors the analog value sent after receiving the detector activation signal from the addressable fire detector 15, and the analog value remains at a predetermined level during a predetermined storage time. If this is the case, the fire will be confirmed.

When the fire receiver 10 receives the detector activation signal from the addressable fire detector 15, the fire receiver 10 transmits a voice output control command to a speaker relay 38 in a corresponding section, for example, a common part. And outputs a confirmation voice message to the voice signal line 9b. The speaker relay 38 receives the voice control output command,
The switch contact 43a of the sound output control unit 43 is turned on, and the common part speaker is turned on by the sound signal line 9b from the fire receiver 10.
, So that a voice signal of a confirmation voice message can be output to the shared part speaker 14.

The operation of the fire receiver 10 when the fire determination signal is received from the addressable transmitter 13 to be installed in the common part and when the fire determination is determined by the accumulation operation processing of the addressable fire detector 15 is determined by the relay. In the same manner as the operation process when the fire determination signal is received from the fire extinguisher 1, the voice output control command is transmitted to the repeater 1 and the speaker transponder 38 in the neighboring section, and the sound signal of the fire alarm message is output and the speaker 6 is output. , 14 output this fire alarm message.

Next, the repeater 1 shown in FIG.
Next, a sensor test performed by connecting the above will be described. In the fire alarm system of the present invention, the fire detector 3 installed in each dwelling unit can perform a remote test by connecting the external tester 35 to the repeater 1. For this reason, the repeater 1 is installed in a place that can be operated from the outside of each dwelling unit. Open the cover of the repeater 1 and connect the tester cable 36 of the external tester 35 to the tester connector 8. For remote testing.

In the remote test, the external tester 35 is connected to the tester connector 8 of the repeater 1 as shown in FIG. Operates to switch the switching relay contact 20a provided on the repeater 1 from the a side to the b side, and the relay contact 20b is turned on. Relay control unit 16
Detects that the relay contact 20b is on, detects that the test is being performed, and releases the accumulation operation function.

By switching the switching relay contact 20a, the sensor line 2 is switched to the external tester 35 side.
When the test by the external tester 35 is started in this state, a test signal is transmitted to the fire detectors 3 in the dwelling unit, and the operation test of the fire detectors 3 is performed one by one in order. When the tests on all the fire detectors 3 are completed, the test results are displayed on the display of the external tester 35. By confirming the test result, it is possible to determine the normal end of the test, the abnormal end, and the abnormal sensor number.

When the test is normally completed, a test normal completion signal is transmitted from the external tester 35 to the repeater 1, and is input to the receiving circuit 19, thereby generating a pseudo alert state. The repeater control unit 16 that has received the false alarm signal from the receiving circuit 19 immediately transmits the fire receiver 1 via the transmission control unit 18 because the storage operation function has been released.
Send a fire confirmation signal to 0. The operations of the fire receiver 10, the repeater 1, and the like after the transmission of the fire determination signal are the same as the above-described operations.

Normally, at the time of the test using the external tester 35, since the fire receiver 10 also has test personnel, a fire display signal is displayed on the display unit 27 when the fire receiver 10 receives the fire determination signal. And the area display of the fire dwelling unit `` ○
By displaying "Fire occurred on floor XX, Room XX", it can be confirmed that the transmission function from the repeater 1 to the fire receiver 10 was also performed normally.

The test staff operating the external tester 35 can check whether the system is normal or abnormal by checking the display status of the outdoor display 7 and the status of the voice message output from the common part speaker.

As the external tester 35 for performing the remote test of the fire detector 3 connected to the repeater 1 as described above, for example, a "remote tester of a fire alarm system" disclosed in JP-A-11-259787 is used. Can be.

The addressable fire detector 15 installed in the common part is provided with an automatic test function, so that a specific addressable fire detector 15 is designated from the fire receiver 10 and a test command signal is issued. To perform an automatic test. When the sensor with the automatic test function receives the test command together with its own address, it performs a test operation and returns a test result to the fire receiver 10. Further, since there is no problem that the fire detector 3 in the dwelling unit cannot enter at the time of the test as in the case of the fire detector 3 in the dwelling unit, the fire detector 3 does not need to have the automatic test function. In this case, the test is performed by directly applying heat or smoke to the fire detector as in a normal fire detector.

In the above-described embodiment, a power supply line is separately provided, and an operating voltage to the fire detector 3 is generated by the constant voltage circuit 21 of the repeater 1 upon receiving power supplied by the power supply line. Although the power supply is supplied to the sensor line 2, the power supply line is not separately provided, and the operating voltage for the fire detector is generated from the voltage flowing through the transmission line and supplied to the sensor line 2. good.

In the above embodiment, a self-restoring fire detector is used as the fire detector for the repeater. However, a self-holding fire detector is also applicable. However, when a self-holding fire detector is applied, the accumulation operation processing in the repeater is slightly different. In this case, the accumulation operation processing includes, for example, once the operation of the sensor is first detected, the power supply to the sensor line is temporarily shut off, and when the fire sensor is activated after a predetermined accumulation time or after the interruption, When an operation is detected, a fire determination signal for determining a fire is transmitted.

The present invention is not limited to the above embodiment, but includes appropriate modifications without impairing the objects and advantages thereof. Further, the present invention is not limited by the numerical values shown in the above embodiments.
