However, the present invention is not limited to this, and may be a so-called P-type receiver in which a plurality of lines are connected in parallel for each of the fire detectors S and the transmitters P installed on each floor. .

In the normal monitoring state, the fire receiver 1 monitors an abnormal operation and a disconnection of the line by polling via the detector line L1 based on the address information of the fire detector S. In such a state, when one of the fire detectors S issues a warning and receives a fire signal by an interrupt signal, the following operation is performed. Upon receiving the fire signal, the fire receiver 1 turns on or blinks an indicator light (not shown) indicating the operation of the fire detector S, and issues the fire detector S
Illuminates or blinks a district window (not shown) corresponding to the installation location of, and outputs an alarm sound from a built-in acoustic device (not shown). Then, an alarm is output from a local sound device (not shown) set in advance corresponding to the fire detector S, and a smoke prevention device (not shown) is operated to form a smoke discharge section. I have. That is, the fire receiver 1 is connected to a smoke elimination device such as a fire door through a smoke elimination line (not shown), and a district sound device such as a bell through a district acoustic line (not shown). When the occurrence of a fire is confirmed, these are controlled in an interlocked manner.

Further, since the emergency broadcast equipment 2 is connected to the fire receiver 1, the emergency broadcast equipment 2 sends a fire broadcast and a sensor S to speakers SP installed at various places.
, And non-fire broadcasts, etc., to notify that a false alarm has occurred. The present invention relates to a fire receiver 1
However, the operation when transmitting and outputting a signal to the emergency broadcast facility 2 is characterized. Therefore, the inside of the fire receiver 1 is configured as shown in FIG. In the figure, 10 is CP
U, etc., and a signal processing unit for controlling the following units,
1 is a receiving unit for receiving a signal through the sensor line L1, 1
2 constitutes the control means of the present invention together with the signal processing unit 10, determines which building of the building the signal received by the receiving unit 11 is from, and outputs the signal to the emergency broadcast facility 2. The ridge discriminating unit 13 for determining whether or not the fire detector S constitutes a storage means of the present invention. (Underground 1
, A first-floor, second-floor,...), A read-out table storage unit 14 classified and stored for each district, constitutes a transfer output unit of the present invention, and broadcasts from the speaker SP to the emergency broadcast facility 2. A transfer output unit for performing a transfer output for causing
A display unit 16 configured with a T, a liquid crystal screen, or the like, for displaying a fire occurrence location, and the like, and an operation unit 16 configured with various switches and the like for instructing the fire receiver 1 on various operations.

A transmission output line L connecting the fire receiver 1 and the emergency broadcast equipment 2 transmits and outputs a fire confirmation signal so that the fire receiver 1 can perform a fire broadcast to the emergency broadcast equipment 2. Signal line (terminal) EF to be transmitted, and a floor-by-floor signal line for transmitting and outputting a floor-by-floor signal indicating the floor on which the fire detector is installed in order to broadcast the operation of the fire detector S ( Terminals) EA1 to EAn. The floor-specific signal lines EA1 to EAn are provided by the number of floors of the entire system. That is, in the case of FIG. 2, the building A (the first floor to the mth floor).
And the same number of floors in both Building B (1st floor ...).

In the fire receiver 1, when one of the plurality of fire detectors S operates and the receiving unit 11 receives a fire signal, the ridge discriminating unit 12 stores the reading table storage unit 13.
, The building data in which the fire detector S is set is obtained. When the operation of the detector S is the first operation of the fire detector S in the same building of the building, the transmitter S is installed from the transmission output unit 14 to the emergency broadcast equipment 2. Transfers and outputs the floor-specific signal of the selected floor.
When the operation of this sensor S is the operation of the second or more fire sensors S in the same building of the building, the transfer output unit 14 transfers and outputs a fire confirmation signal.

As described above, in the present invention, even if the system configuration is a building including a plurality of buildings, the fire detector S is counted for each building to perform fire broadcasting. As in the conventional case, the operation of the fire detector S is counted in the entire system, and a fire broadcast is prevented from being erroneously performed. Specifically, when the emergency broadcast facility 2 receives the signal for each floor, the emergency broadcast facility 2 automatically inserts the floor into a voice message and says, "The fire detector on the ○ floor has just been activated. Please be aware of the following broadcast. "(Sensor-activated broadcast), for example, by female voice, and then receive a fire confirmation signal,
A broadcast (fire broadcast) such as "Fire is on fire. A fire has occurred on the floor. Please calm down and evacuate."

After receiving the floor signal, the operation unit 16 is operated by a person or the like who has confirmed that the operation of the detector S was incorrect without receiving the fire confirmation signal.
When receiving the recovery signal from the fire receiver 1, a broadcast (non-fire broadcast) such as "The operation of the fire detector just before was not abnormal as a result of confirmation. Please be assured."

When the receiver 11 receives a fire signal due to the operation of the transmitter P, the fire receiver 1 transmits a fire confirmation signal from the transmission output unit 14 to the emergency broadcast equipment 2. Output. This is different from the case of the operation of the fire detector S, in which a fire signal is received due to a human operation. Therefore, even if the transmitter P in any building is operated, a fire broadcast is immediately performed. Works like that.

Further, the receiving unit 11 receives the restoration signal via the sensor line L1 because the fire detector S no longer detects the cause of the fire or the transmitter P is restored. At this time, the fire confirming signal or the floor-by-floor signal transmitted and output by the transmission output unit 14 to the emergency broadcast facility 2 is stopped. Also in this case, the emergency broadcast facility 2 can perform the non-fire broadcast indicating the misinformation.

When the restoration signal is received, the ridge discriminating unit 12 refers to the ridge in which the restored fire detector S and transmitter P are set from the replacement table storage unit 13 and It operates according to such recovery conditions. The source of the restoration signal is the fire detector S, and this restoration also
When the remaining two or more fire detectors S in the same building of the building are still operating, the transmission output of the fire confirmation signal and the floor-specific signal is continued. When the transmission output is stopped and all the fire detectors S are restored, all the transmission outputs (fire confirmation signal, all floor signals) are stopped. On the other hand, when the transmitter P recovers, if no other transmitter P is operating and two or more fire detectors S are not operating in the same building, the transmission output of the fire confirmation signal is stopped. .

FIG. 3 shows an example of the configuration of the replacement table storage section 13 (read table). This storage unit 13
It is composed of a nonvolatile memory, such as an EPROM or an EEPROM, and is installed at an appropriate place in a building.
In the table, an address assigned so as not to overlap each other and an installation location (building, floor, district) corresponding to the address are set. Note that the address and the installation location of the transmitter P are set in the same manner, and "number" data for further specifying the installation location may be added to the installation location.

FIG. 4 is a flowchart showing the operation of the fire receiver 1 when receiving a fire signal. Here, a fire signal counter (Ta for Building A, Tb for Building B) is provided for each building, and a signal to be transmitted and output is determined based on the counter values Ta and Tb. When a fire signal is received, the received fire signal is sent from the fire detector S based on the address in the signal, and the received fire signal is from the fire detector S. , A floor-specific signal is transmitted and output from the second and subsequent fire detectors S, and a fire confirmation signal is transmitted and output.
If the signal is a fire signal from the transmitter P, a fire confirmation signal is transferred and output irrespective of the counter values Ta and Tb (100 to 107).

Next, another configuration of the fire alarm system of the present invention will be described. FIG. 5 is a block diagram showing a main configuration of the fire alarm system, and FIG. 6 is a diagram showing an entire configuration of the fire alarm system. The system configuration shown in FIG.

Therefore, each transmission output line La, Lb connecting the fire receiver 1 and the emergency broadcast equipment 2 is connected to a fire confirmation signal to cause each of the emergency broadcast equipments 2a, 2b to perform a fire broadcast. In order to transmit the fire confirmation signal lines (terminals) aEF and bEF and to transmit the operation of the fire detector S, a floor-specific signal indicating the floor where the fire detector is installed is transmitted and output. Floor-specific signal lines (terminals) aEA1
aEAn, bEA1 to bEAn. That is,
Signal lines aEA1 to aEAn, bEA1 to bEAn for each floor
Is provided for each floor of each building.

When the fire receiver 1 receives a fire signal by one of the plurality of fire detectors S, the fire discriminating unit 12 refers to the read-out table storage unit 13 and The building data in which the fire detector S is set is obtained. When the operation of the detector S is the first operation of the fire detector S in the same building of the building, the emergency broadcast facilities 2a and 2 provided corresponding to the building are operated.
For b, the transmission output units 14a and 14b corresponding to the emergency broadcast facilities 2a and 2b transfer and output floor-specific signals of the floor where the sensor S is installed. When the operation of the detector S is the operation of the second or more fire detectors S in the same building of the building, the emergency broadcast facilities 2a and 2b provided corresponding to this building are transmitted to the fire detectors S. Emergency broadcasting equipment 2
A fire confirmation signal is transferred and output from the transfer output units 14a and 14b corresponding to a and 2b.

In this configuration as well, even if a building consisting of a plurality of buildings is the target, the operation of the fire detector S is counted for each building, and each emergency broadcast facility 2a,
Since the fire broadcast is performed in 2b, the system scale can be expanded more than before. In addition, when the receiving unit 11 receives a fire signal by one of the operations of the plurality of transmitters P, the fire receiver 1 refers to the replacement table storage unit 13 and the transmitter P is installed. To the emergency broadcast facilities 2a, 2b provided corresponding to the building, the transmission output units 14a, 14b corresponding to the emergency broadcast facilities 2a, 2b transmit and output a fire confirmation signal.

Further, even when the receiving unit 11 receives a restoration signal via the sensor line L1, if the restoration condition for each building is satisfied by referring to the read-out table storage unit 13, the restored fire is detected. For the emergency broadcast facilities 2a, 2b of the building where the sensor S or the transmitter P is installed, the emergency broadcast facilities 2a, 2b
The fire confirming signal or the floor-specific signal output from the transfer output units 14a and 14b corresponding to b is stopped.
