DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to an additional power supply box.

[Conventional technology]

Fig. 3 shows the local sound equipment Bell B and the local sound terminal of the self-fire alarm receiver installed in the building 3 on the first floor underground and the fourth floor above ground on the first floor, ... 4F where automatic fire alarm system is installed. Voltage output) B ₁ , ... B ₅ , B _C and district sounding sound output terminal 1 having a sound terminal immediately above the fire floor (no-voltage output) K ₁ , ... K ₅ , K _C is there.

In Fig. 3, if a fire occurs on the first basement floor BF, the first basement floor BF
Bell B sounds on the first floor and the first floor. If a fire occurs on the first floor, the bell B on the first basement floor BF and the first and second floors will ring and the second floor will ring.
If a fire occurs on the second or third floor, the fire floor and the bell B on the floor immediately above will ring, and if a fire occurs on the fourth floor, the fourth floor will be bell B
Only connected to ring. Such a connection method is called a fire floor immediately above the fire floor. There are various other ringing methods.

In the figure, the relay contacts ^{_{(R 1 B, R 1 K}} ), ... (R 5 B, R 5 K)
Are controlled in the self-fire alarm receiver so as to close when the corresponding fire alarm line numbers 1,..., 5 are fired. And
Although not shown in FIG. 3, the fire alarm line numbers 1,..., 5 correspond to each floor of the building 3, that is, the first floor BF to the fourth floor 4F.
Then, they are laid to detect the fire.

By the way, the power supply 2 which normally receives power supply from the commercial power supply and receives power supply from the storage battery during power failure and outputs a predetermined voltage is a power supply for the entire self-fire alarm receiver and a local acoustic terminal (voltage output). B _1, ... B _5, B serves to supply and _C, the positive pole of the power supply 2 relay contact R ¹ _B, ... R ⁵ each terminal B ₁ through _B, ... terminal I while connected to B _{5 +} , And to terminal B ⁺ _L via relay contact _RBL which operates when there is a fire input on any fire alarm line.

On the other hand, as the negative pole of the power source 2 is connected to the terminal B _C via a relay contact R _BC to work with local sound switch deer paper receiver (not shown), described above the fire alarm system of the building 3 to the Do fire floor just above floor ringing; individual terminals K _1, respectively in ... K ₅ relay contact R ¹ _K, ... and a terminal K _C and the terminal B ⁺ _L connected through the R ⁵ _K outside connection with hardwired, the terminal B ₁ and the terminal B _2, and a terminal K ₂ and the terminal B _3, and a terminal K ₃ and the terminal B _4, terminal K ₄ and the terminal B ₅ and the respectively external wiring I do. Also, the bell B on each floor from the first basement floor BF to the fourth floor 4F of the building 3 has terminals B ₂ , B ₂ , B ₃ , B ₄ , B ₅
And the common terminal B _C, respectively connected through the outside line _{W 1, ... W 5, W} C.

By the way, the installation range of the bell B is regulated by law, and in recent years, the number of bells B installed in one building of a condominium such as an apartment has become larger than before. For this reason, it has become clear that the capacity of the power supply 2 is insufficient after the building is connected to, for example, the ringing method immediately above the fire floor shown in FIG. 3 specified in the building.

In this case, the power supply 2 of the capacity shortage can not be used for the ringing of the bells B, chromatic voltage output terminal B ₁ of the local sound sound output section 1 of the deer report receiver, ... to B _5, B _C, Bell B cannot be connected directly.

Therefore, as shown in FIG. 4, a power supply box 4 which receives power from a storage battery and supplies a predetermined voltage at the time of a power failure, and a relay R having an a contact, are provided. , and interlocking combined terminal block 5 the diode 6 is inserted respectively between the terminals ready disposed near the deer report receiver, the ringing of the building 3 using a terminal _{K 1, ... K 5, K} C Reconnection is performed so as to be a system (in this example, a sounding system immediately above the fire floor) or, though not shown, a power supply box and an appropriate number of relays having an a contact (four in the case of FIG. 3). Prepared and installed near the self-fire alarm receiver, and use a wire to provide a voltage output terminal (in the case of FIG. 3) so that the sound system of the building 3 (in this example, the sound system immediately above the fire floor). Is the terminal B ₁ ,
.. B ₅ , B _C ) are respectively connected to the exciting section of the relay, one of the a contacts of the relay is connected to one pole of the power supply of the power supply box, and the other of the a contacts of the relay is respectively connected. electric line of the bell B (electric line W ₁ in the case of FIG. 3, ... W ₅₎ connected to a common electric line of power other pole of the bell B (in the case of FIG. 3 common electric line W _C) Needed to be connected to.

[Problems to be solved by the invention]

In other words, after connecting a bell as a district sound device to the district sound ringing output terminal of the self-fire alarm receiver so that the building will ring at the site, it became clear that the power capacity of the self-fire alarm receiver was insufficient. However, if it becomes necessary to sound the bell as a district sound device in a power supply box, which is another power supply, the power supply box, the a-contact relay, and the terminal block for interlocking combination should be prepared and arranged near the self-fire alarm receiver. After the installation, the connection already made to the district sounding sound output terminal part is completely re-wired to achieve the purpose. After the power supply box and the appropriate number of a-contact relays are prepared and arranged near the self-fire alarm receiver Achieve the purpose by connecting the connection removed from the district sounding output terminal to the power supply box via the a contact of the a contact relay, and connecting the excitation section of the a contact relay to the district sounding output terminal instead. Need to do , Together with the prepared arrangement requires members respectively, it is necessary for connecting it, there is a problem that a very time-consuming and 働力.

The present invention has been made in order to improve the above-mentioned problems. The purpose of the present invention is to reduce the labor and labor required for procurement, installation, and wiring of necessary components, and to provide a power supply method to a load.
