The transmission / reception unit 4 collects state information from the fire detector 3 by polling or the like. Reference numeral 6 denotes a fire determination unit connected to the transmission / reception unit, which determines whether or not a fire has occurred by comparing state information (sensor level) from the fire detector 3 with a predetermined fire threshold.

Reference numeral 7 denotes a reporting unit as reporting means. The reporting unit includes a modem connected to a telephone line and an automatic dialer for calling a security company, and when a fire occurs, notifies the security company K, which is an external output destination, that the fire has occurred.

Reference numeral 8 denotes an operation switch provided on the panel of the fire receiver 1. A plurality of operation switches 8 are provided and connected to the switch operation unit 9. The switch operation unit 9
The state of the switch, that is, whether the switch is on or off is set, and the state of the switch is output to the control unit 2. When the operation switch 8 is operated, an operation signal is output to the control unit 2 via the switch operation unit 9, and the control unit 2 performs control according to the operation signal.

Reference numeral 11 denotes a switch state storing means for storing a normal state of the operation switch 8. As shown in FIG. 2, the switch state storage unit 11 stores, for each switch,
At normal times, it stores whether it is set to ON or OFF.

Reference numeral 12 denotes a switch determining means for determining whether or not the operation switch 8 is in the state stored in the switch state storing means 11, that is, in the localization state. 13
Is a switch storage means connected to the switch determination means 12. The switch storage means 13 stores information on the operation switch 8 when the operation switch 8 is different from the normal state. Reference numeral 14 denotes an alarm display unit, such as a buzzer or an LC.
D for performing a fire alarm and a fire display in the event of a fire.

The switch storage means 13 is connected to the notification unit 7, and the notification unit 7 notifies the stored information of the operation switch 8 to the alarm company K, which is an external output destination. I have. In particular, when the fire detector 3 operates, that is, when a fire occurs, the notification unit 7 notifies the user that the fire has occurred at an external output destination and the switch storage unit 13
The information of the operation switch 8 stored in the.

The switch storage means 13 is constituted, for example, as follows. The switch storage unit 13 has a comparison table corresponding to the operation switch 8. When the type of the operation switch that is not in the fixed position is sent from the switch determination unit 12, a flag is added to the operation switch part in the comparison table. Build

Next, the operation of the present invention will be described. By the polling performed by the transmission / reception unit 4, the fire detector 3 outputs a sensor level at a predetermined cycle. The fire determination unit 6 compares the sensor level with the fire threshold to determine whether a fire has occurred. Here, when the fire determining unit 6 determines that a fire has occurred, a fire signal is output to the control unit 2.

The control unit 2 outputs the fire signal to the alarm display unit 14, the switch discriminating means 12, and the notification unit 7 in response to the input of the fire signal. This case will be described sequentially below. First, the alarm display unit 14 is operated in response to the input of a fire signal, sounds a buzzer, and displays on a display unit comprising an LCD that a fire has occurred.

The operator of the fire receiver 1 operates the operation switch 8 based on a message displayed on the LCD and the like. The on / off state of the operated operation switch 8 is set in the switch operation section 9, and the control section 2 is provided as an operation signal.
Is output to The control unit 2 performs a process according to the operation switch 8 according to the input of the operation signal. For example, operation switch 8
When the main sound stop switch is turned on, the setting state of the main sound stop switch in the switch operation section 9 is switched from off to on, and the sounding of the main sound in the alarm display section 14 is stopped. .

Next, the switch determining means 12 operates in response to the input of the fire signal. The switch determination means 12 stores the switch setting state of the switch operation unit 9 and the switch storage means 1.
Compare the normal switch state stored in 1 with the switch state. Then, only the information of the operation switch 8 which is not at the fixed position is read from the switch operation unit 9 and stored in the switch storage unit 13. Here, since the main sound stop switch 8 has been turned on earlier and the state stored in the switch storage means 11 is different, it is assumed that the "main sound stop switch" is different from the normal state and the switch storage Means 1
3 is stored.

The notification unit 7 receiving the fire signal notifies the security company K via a telephone line that a fire has occurred. At this time, the notification unit 7 reads the information of the operation switch 8 stored in the switch storage means 13 and notifies the security company that the operation switch 8, here the main sound stop switch, is in a state different from normal. Notify K when a fire occurs.

In this embodiment, when a fire occurs, an operation switch, particularly an operation switch that is not in a fixed position, is notified to an external output destination. However, for example, a timer is provided so that a security company as an external output destination can be notified. While the notification unit is connected to the telephone line, the information stored in the switch storage unit may be reported (transmitted) in real time or every ten or more seconds. By doing so, the person at the security company can confirm how the operator of the disaster prevention center operates the fire receiver.

In this case, the timer outputs a start signal to the control unit every ten or more seconds, and the control unit performs the same processing as when receiving the start signal and when receiving the fire signal. A signal may be output from the security company. In this case, when the control unit receives this signal, the information stored in the switch storage unit is reported. Also, a signal for controlling the operation switch may be output from the security company via a telephone line, and upon receiving this signal, the control unit of the fire receiver changes the state of the target operation switch from on to off or off. Switch from off to on.

By controlling the operation switch of the fire receiver of the disaster prevention center from the security company, it is possible to prevent the fire receiver operator from performing an erroneous operation when the operator is unfamiliar with the operation. Can be.

[0022]

The present invention is constructed as described above, and the state of the operation switch provided on the fire receiver is reported to an external output destination. The situation is easy to grasp, and it is easy to explain the operation method and the like to the fire receiver operator at the site.

Since the information of the operation switch sent to the report destination is only the operation switch which is different from the normal operation and is not in a fixed position, the communication volume is small, and the security company can quickly grasp the state of the fire receiver. it can.
