Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a security device that can be connected in parallel.

BACKGROUND OF THE INVENTION Security devices that can connect multiple devices in parallel are generally known, but in any of these devices, if a fire, gas leak, etc. is detected in any of the security devices,
It simply transmits the information to other security devices, and it simply emits an alarm sound in response to a fire, gas leak, etc. from multiple security devices connected in parallel. be.

Problems to be Solved by the Invention Therefore, with this type of device, even if an alarm sounds, it is impossible to tell which security device has detected a fire, gas leak, etc., and even if you are actually present at the scene, you will not be able to tell. The problem was that they were too intimidated to take immediate action.

The present invention eliminates the above-mentioned conventional drawbacks, and in security devices connected in parallel to each other,
An excellent security device that can accurately display which security device detected a fire, gas leak, etc., if any of the security devices detects a fire, gas leak, etc. The purpose is to provide.

Means for Solving the Problems In order to achieve the above object, the present invention provides means for setting its own device number, and stores information corresponding to the device number set by the means.

When a gas leak, etc. is detected, the information is transmitted to other security devices, and when the above information is transmitted from another security device, the information corresponding to the device number in that information is transmitted. It is configured to display which security device has detected a fire, gas leak, etc.

Therefore, according to the present invention, when any security device detects a fire, gas leak, etc., it is possible to accurately determine which security device detected the fire, gas leak, etc. In addition to the display, it has the effect of allowing immediate response to be taken by looking at the display of either security device.

Embodiment FIGS. 1 and 2 show the configuration of an embodiment of the security device of the present invention. In FIGS. 1 and 2, A, B, and C are security device bodies having the same structure, and these security device bodies A, B, and C are connected in parallel to each other. 1 is a fire connected to each security device body A, B, and C.

2 is a sensor input detection circuit that detects the operation of sensor 1; 3 is a logic circuit; 8 is a warning device display circuit; 9 is a signal receiving circuit; 1° is a signal output terminal;
11 is a signal input terminal, 12 is a speaker, and 13 is a display device.

In the above embodiment, when the sensor 1 connected to the first device body A detects a fire, gas leak, etc., the signal is detected by the input detection circuit 2 and input to the logic circuit 3. When a signal from the input detection circuit 2 is input to the logic circuit 3, the logic circuit 3 determines whether the signal is caused by a fire or a gas leak, and transmits the corresponding signal to the alarm issuing circuit 6.
to communicate. Therefore, in this state, the alarm circuit 6 outputs a signal corresponding to the type of fire, gas leak, etc., and causes the speaker 12 to output an alarm sound corresponding to the type. At the same time, the logic circuit 3 takes out its own device number preset by the device number setting circuit 7, and sends it to other devices through the signal sending circuit 4 along with a signal corresponding to the type of fire, gas leak, etc. determined earlier. It is transmitted to the device main body B and C sides. When the signal corresponding to the type of fire, gas leak, etc. and the signal corresponding to the device number are input to the other device bodies B and C,
The signal is input to the signal judgment logic circuit 6 via the signal receiving circuit 9, where the signal is judged and transmitted to the logic circuit 31 and the alarm device display circuit 8, respectively. Therefore, the logic circuit 3 transmits a signal depending on the type of fire, gas leak, etc. to the alarm issuing circuit 6, drives the alarm issuing circuit 5, and fires from the speaker 12.

An alarm sound corresponding to the type of gas leak, etc. is outputted, and the alarm device display circuit 8 lights up the display 13 corresponding to the device number based on the signal corresponding to the device number. Therefore, even in other device bodies B and C, the alarm sound from the speaker 12 indicates the type of fire, gas leak, etc., and the display 1
It is possible to easily know which sensor 1 connected to the main body of the device is operating and emitting the alarm sound based on the lighting state of 3.

In this embodiment, the type of fire, gas leak, etc. is indicated by the alarm sound, but a separate display is provided, and the type of fire, gas leak, etc. is indicated by the display. It may be configured as follows.

Effects of the Invention As is clear from the above embodiments, the present invention is provided with a device number setting means for setting its own device number, and the information corresponding to the device number set by the setting means is transmitted to
Fire occurs when gas leaks occur.

A signal that distinguishes the type of gas leak, etc. is transmitted to other security devices, and when the above-mentioned signal arrives from another security device, the sensor connected to which security device detects a fire or fire based on that signal.
This system is configured to display whether a gas leak, etc. has been detected using a separate display, and the location where a fire, gas leak, etc. has occurred can be immediately known from the display on the above display, and the location can be immediately detected. This has the effect that it is possible to take appropriate measures.
