[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire receiver used in a fire alarm system for buildings, condominiums, and the like, and more particularly, to a fire in which connection between a voltage contact output terminal and a non-voltage contact output terminal can be easily switched. Regarding the receiver.

2. Description of the Related Art Conventionally, a fire alarm of a fire alarm system has been used which controls the sounding of a main sound and a district sound, lighting of a district light, etc. in response to a fire alarm from a fire detector. . FIG. 5 and FIG. 6 are schematic diagrams showing the essential parts of a conventional fire receiver.

The fire alarm receiver 100 shown in FIG. 5 is provided with a plurality of contact output terminals b1 to bn, and a district bell B is connected to each of the contact output terminals b1 to bn, and is connected via a monitoring line (not shown). If there is a fire alarm from a fire detector (not shown) connected to the relay contacts r1 to r1 corresponding to the monitoring line.
By closing rn, the district bell B provided between each of the contact output terminals b1 to bn and the common terminal bc was rung.

However, in recent years, in order to inform the situation of fire occurrence in more detail, a fire alarm system equipped with an emergency broadcast facility with a voice alarm has been widely used in place of the district bell B.
FIG. 6 shows a fire receiver used therein. In addition to the configuration shown in FIG. 5, the fire receiver 101 has a fire relay ry1 in order to connect the emergency broadcast facility 10 with an audio alarm.
To ryn are provided. For example, when the relay contact r1 ′ is closed, the fire relay ry1 connected between b1 ′ and bc ′ is driven, and the relay contact ry1a is closed, so that a no-voltage output occurs between e1 and ec, and the signal line L is generated. A broadcast instruction is output to the emergency broadcast facility 10 via the broadcast instruction.

That is, when the fire detector issues a warning, the fire receiver 101 receives this, and the fire receiver 101
The alarm signal and the fire occurrence floor are transmitted to the emergency broadcast facility 10 with a voice alarm via the signal line L, and the fire occurrence etc. are broadcast from the emergency broadcast speaker to the fire occurrence floor and the floor immediately above the fire occurrence floor or the entire building all at once.

[0006]

However, in the above-mentioned conventional fire receiver, when the connection is changed from the district bell to the emergency broadcast facility with voice alarm, another relay is added to the conventional voltage output circuit to eliminate the need. It is necessary to change to the voltage output circuit,
Therefore, the cost is increased by adding circuits, and
I was spending a lot of time working on the changes.

The present invention has been made in view of the above points and provides a fire receiver in which a voltage output circuit can be easily changed to a non-voltage output circuit without adding another circuit. The purpose is to provide.

[0008]

A fire receiver according to the present invention, which is proposed to achieve the above object, is connected to a monitoring line to which a fire detector is connected, and is connected to a fire detector. It is equipped with a fire reception circuit section equipped with a corresponding fire relay and a transfer output section installed corresponding to this fire relay. The transfer output section has a common terminal and a drive power supply for the fire receiver. Is provided with a plurality of contact output terminals corresponding to the fire relay via the first connecting portion, and a contact of the fire confirmation relay is provided on the output side of the first connecting portion via the second connecting portion. The configuration is such that an output terminal is provided.

Here, the fire confirmation relay is designed to be activated by the second notification from the fire detector, and is provided so as not to make an erroneous emergency broadcast or erroneous ringing of the district relay. The fire receiver according to the present invention as set forth in claim 2 has a structure in which the transfer output section is provided with a control contact of a transfer stop relay interlocked with a recovery switch, and the control contact of the transfer stop relay is usually Is closed and can be opened by operating the recovery switch when you want to stop the emergency broadcast.

In the fire receiver according to the present invention as defined in claim 3, the first and second connecting portions are formed by connecting jumper wires.

[0011]

In the fire receiver according to the first aspect of the present invention, when the first connecting portion is closed and the second connecting portion is opened, the plurality of contact output terminals become voltage contact output terminals. A load such as a district bell can be connected between the output terminal and the common terminal. Further, when the first connecting portion is opened and the second connecting portion is closed, the plurality of contact output terminals become non-voltage contact output terminals, so that the output terminal can be connected with the emergency broadcast facility with audio alarm.

In the fire receiver according to the second aspect of the present invention, since the transfer can be stopped by the recovery switch, the operation of the recovery switch and opening of the contact facilitates the inspection work of the emergency broadcast facility with voice alarm. You can do it. In the fire receiver according to the present invention as set forth in claim 3, since the non-voltage output and the voltage output can be switched by connecting the jumper wire, it is easy to change the connection of the voltage and the non-voltage load connected to the fire receiver. It can be done in a short time.

Although the embodiment of the present invention has been described above, the first and second connection portions of the transfer output unit 3 do not necessarily have to be connected by jumper wires, and a voltage output is made by a switch operation or the like. Alternatively, the non-voltage output may be switched.

[0020]

According to the fire receiver of the present invention described in claims 1 and 3, the same plurality of contact output terminals can be provided only by changing the connection of the first and second connecting portions. Since the voltage contact output terminal can be changed to the non-voltage contact output terminal or the non-voltage contact output terminal can be changed to the voltage contact output terminal, the work accompanying the change of the connected equipment can be immediately performed. Further, according to the fire receiver of the third aspect, since the change can be made only by connecting the jumper wire, even a person who does not have specialized knowledge can easily work.
