In addition, each house information board D,
It is also connected to an alarm monitoring panel H installed in a manager's room or the like, so that the monitoring status of each dwelling unit is centrally managed, and by a standby power supply device I provided in a dwelling receiver B. , In case of power failure, the power supply is backed up.

FIG. 5 is a block diagram showing the internal structure of the common-use receiver A of the various fire receivers described above. This common-use receiver A includes a detector line Ls (LC) to which a fire detector S is connected, and a common-use speaker S.
The acoustic line Lsp (SP-SPC) to which P1 is connected is connected, and the residential building receiver B is connected via a signal line Lab. Further, by connecting the terminal J1 to the test terminal J, the operation test by the remote tester C is also possible.

In the figure, 101 is an information processing circuit composed of a CPU or the like, 102 is a display unit composed of a liquid crystal screen and various kinds of indicator lights, 103 is an operation unit composed of various switches, and 104 is a common part. A voice output circuit for outputting a fire alarm as a voice message or the like from the speaker SP1 or the internal speaker SP2, 105 is a fire alarm signal to the residential building receiver B via the sensor line (JL-JC) of the signal line Lab. A fire transfer circuit for output, 106 is an alarm control receiving circuit for receiving an alarm control signal from the residential building receiver B via the district bell line (B-BC), and 107 is the residential building receiver B and the signal line Lab (T). -TC), a telephone terminal for connecting a telephone in order to make a telephone call, 108 is a fire / disconnection detection circuit for detecting the alarm of the fire detector S and the disconnection of the detector line Ls, 1
Reference numeral 09 is a test detection circuit for detecting the connection (during a test) of the remote tester C, and 110 is a power supply circuit.

To explain the basic operation of this system, if any of the fire detectors S connected to the detector line Ls issues a warning, the fire / disconnection detection circuit 108 detects this. Then, the fire indicator lamp (not shown) of the display unit 102 is turned on or blinks, and the voice output circuit 104 outputs the first fire alarm by an alarm or a voice message from the internal speaker SP2. This first fire alarm notifies the operation of the fire detector S and prompts the resident to confirm whether or not there is a fire. For example,
It is a message such as "Fire detector has activated. Please check."

From the time when this first fire alarm is output,
When a predetermined time (for example, 5 minutes) has passed, or when an emergency switch (not shown) is operated within a predetermined time after confirming the occurrence of a fire, the fire transfer circuit 105 sends a detector line (JL-JC). ), A fire alarm signal is output to the residential building receiver B, but within a predetermined time, the fire detector S that issued the alarm has been restored, and an alarm stop switch (not shown) of the operation unit 103 is operated. The fire alarm signal is not output when

On the other hand, when the fire alarm signal is received by the residential building receiver B, the residential information board D of the dwelling unit, the alarm unit G, etc., which have been set in advance as notification destinations, are transmitted via the district bell line (B-BC). And outputs an alarm control signal. In addition,
At this time, the target of the alarm control signal is a neighboring dwelling unit or the like on the same floor as the common-use receiver A that has output the fire alarm signal, or on the floor directly above.

In the common-use receiver A, after outputting the fire alarm signal, the voice output circuit 104 causes the common-use speaker SP1 to output a second voice message or a siren.
While outputting the fire alarm of No. 2, the second fire alarm is also issued by the house information panel D of the neighboring dwelling unit or the like which has received the alarm control signal from the housing ridge receiver B. Here, the second fire alarm is for notifying the occurrence of an actual fire, and evacuees the residents.
It is something that requires coping. For example, the message is "Fire. It's a fire. There was a fire in ○○. Please check the safety and evacuate." In addition, in the house information board D, it is possible to display the occurrence of a fire on the outdoor display F and output a voice message of the second fire alarm.

The basic operation when an actual fire occurs has been described above. However, in such a fire alarm system,
An operation test can be performed with the remote tester C connected.
When the terminal J1 of the remote tester C is connected to the connection terminal J and the power switch (not shown) of the remote tester C is operated, the relay RT operates and the contact rt closes to detect the in-test detection circuit 109.
Indicates that the test is in progress. After that, contact point r
t1 is switched, and the connection of the sensor line Ls is switched from the fire / disconnection detection circuit 108 to the remote tester C side. At this time, the common-use receiver A detects that the test is in progress, and therefore no abnormality alarm is output due to the disconnection of the sensor line Ls.

In this state, by operating the various switches of the remote tester C, the fire sensor S operation test, the common area receiver A operation test, and the residential building receiver B interlocking test can be performed. It can be implemented.

[0013]

As described above, in the conventional fire receiver, if the fire detector operates, the first fire alarm is output, and if the alarm stop switch is not operated within a predetermined time thereafter, The second fire alarm is output. However, in a condominium where it takes a long time to check the fire detector and confirm the site, the second fire alarm may be output during confirmation, and conversely, a manager etc. may be resident. In an apartment where it is easy to check the cage, the second fire alarm is not output unless the switch is operated, so it may take some time to notify the dwellers of the fire and the evacuation of the dwellers may be delayed. there were.

Therefore, in the conventional fire receiver, it is possible to freely set the delay time of the second fire alarm with respect to the first fire alarm so that the fire alarm suitable for the situation of each apartment house can be issued. However, there was no means to easily check the set time. In addition, when the fire receiver has a storage function, it is difficult to know whether the current state is being stored or being delayed.

The present invention has been made in view of such circumstances, and in the case where the delay time of the second fire alarm with respect to the first fire alarm can be easily confirmed and a storage function is provided. An object of the present invention is to provide a fire receiver in which it is easy to know whether the current state is accumulating or delay time.

[0016]

In order to achieve the above object, a fire receiver according to the present invention comprises the following means. Claim 1 is applied to a fire receiver that does not have a storage function and includes a delay time confirmation switch, and when this switch is operated, the delay time set by the delay time setting unit is displayed on the display unit, Alternatively, a message is output from the voice output unit. Here, the display unit is composed of a liquid crystal screen, an indicator lamp (LED or the like) indicating a set time, and the like, and the delay time is indicated by characters, lighting, and blinking.

The claim 2 is applied to a fire receiver having a storage function, which is provided with a storage lamp and turns on or blinks the storage lamp during the storage time, while starting the output of the first fire alarm. Until the output of the second fire alarm is started, the lighting mode of the storage lamp is changed to light or blink. Therefore, it is not necessary to newly provide an indicator light indicating that the delay time is in progress.
