Description

[Detailed Description of the Invention] [Technical Field] The present invention has an alarm function of fire, crime prevention, gas leakage, etc.,
Moreover, regarding the fire, the present invention relates to a house information board having a transfer output to a fire receiver.

[Background technology]

As shown in FIGS. 1 and 2, the conventional housing information board 2 is connected with the detectors 1 such as the fire detector 1a and the crime prevention detector 1b, and the alarm output from the housing informs the housing information board at the same time. This is a notification output, and in case of a fire, it is output to the fire receiver 3 installed in the manager's room or the like.
As shown in FIG. 2, the electric circuit of the house information board 2 has a fire reception circuit 6 between the power supply circuit 5 and a power supply line A, B via a transformer 4 from a commercial power supply, a crime prevention reception circuit 7 as an example of other alarms, An alarm display circuit 8 for displaying the alarm is connected. For compensation when the commercial power supply is cut off, a storage battery 11 is provided in the housing information panel 2 or is supplied from the outside by a storage battery or another method. However, since the entire housing information panel 2 circuit is compensated, the storage battery for compensation has a disadvantage that a large capacity is required. When the housing information panel 2 has a built-in storage battery, the housing information panel has a large size. It was not suitable for residential use.

[Purpose of device]

The present invention has been made by paying attention to the above-mentioned problems, and when the commercial power supply is cut off, the power is supplied only from the storage battery to the fire reception circuit, and the alarm output is sent to the fire receiver. , The purpose is to reduce the storage battery capacity and make the home information panel smaller.

[Disclosure of device]

The present invention is a house information panel equipped with a fire reception circuit and an alarm reception circuit other than a fire, in which a storage battery for power supply compensation in the event of a power failure is supplied only to the fire reception circuit by a switching relay.

Hereinafter, the embodiment of the present invention will be described with reference to FIG. The same parts as those in FIG. 2 of the conventional example are designated by the same reference numerals. The house information board 2 is provided with a transformer 4 connected to a commercial power source and a power supply circuit 5, and a fire reception circuit 6 between the power supply lines A and B, a gas leak other than a fire, and a crime prevention reception circuit 7 as an example of crime prevention. It is connected. And these fire, crime prevention receiver circuit 6,7
Alarm display circuit 8 for issuing an alarm and display in response to reception of
Is connected. The fire detector 1a is installed in the fire receiving circuit 6,
A crime prevention detector 1b is connected to the crime prevention reception circuit 7. The fire reception circuit 6 and the crime prevention reception circuit 7 respectively have contacts 9 and 10 for transmitting a signal to the outside of the housing information board. And power lines A and B
A relay 12 for power supply switching is connected between them, and the contact of this relay is normally closed between the power supply line A and the fire reception circuit 6, and when the power is cut off, the storage battery 11a and the fire reception circuit 6 are connected. Is switched to the side where electricity is conducted. The storage battery 11a may be built in the house information panel 2, provided externally, or supplied from an in-house generator.

Next, the operation will be described. When the power is cut off due to a power failure or the like in a normal alert state in which commercial power is supplied, the relay 12 for power switching is demagnetized and its contact is switched, and the fire reception circuit 6 supplies power from the storage battery 11a side. receive. Although the other crime prevention reception circuit 7 and the alarm display circuit 8 are inoperable, the fire detector 1a and the fire reception circuit 6 remain in an operable state and the transfer contact 9 is also operable, so the fire receiver It is possible to give an alarm to the third grade. In addition, the storage battery 11a is installed in the housing information board 2
If the storage battery 11a is built in, the housing information panel 2 can be downsized as much as the storage battery 11a is downsized.

[Effect of device]

As described above, according to the present invention, a fire receiving circuit to which a fire detector is connected and which has a contact for transfer, a receiving circuit to which a detector other than fire such as crime prevention and gas leakage is connected, and the fire receiving circuit, , In the case of a house information board that connects an alarm display circuit that responds to the reception of a fire reception circuit or a reception circuit other than a fire to a power line, if it is detected that the normal power supply of the house information board is cut off, a notification is sent. Since only the fire reception circuit with a contact for switching is switched from the normal power supply to another power supply by the switching contact, even if the power is cut off due to a power failure or abnormality of the power supply circuit For fire alarms, which have a high degree of importance, the fire reception circuit and its transfer contacts can operate, so reliable home information can be transmitted to external devices such as fire receivers with managers. While being a board, Be built in the pond in the residential information panel, the battery has an advantage that housing information panel itself can also be formed in small size because it is small.
