Embodiment FIG. 1 is a front view showing an embodiment of the present invention. In this embodiment, a template T is installed in the operation section 10 of the fire receiver 1.

FIG. 2 is a front view of the fire receiver 1 in the above embodiment in which the template T is not installed in the operating section 10. 3 is an enlarged view of the operating section 10, and FIG. 4 is an enlarged view of the template T.

The operation unit 10 includes a fire light 11 and an indicator light 12.
, a number display section 13, a number setting switch 14, various switches SW, and insertion holes H1 and H2.

In FIG. 3, the circle marks indicate lamps, and the small square marks indicate switches. Furthermore, insertion detection switches SW1 and SW2 are provided at the lower portions inside the insertion holes H1 and H2. These switches SW1 and SW2 are connected to the protrusions T1 and T of the template T.
2 is a switch that detects the insertion state when inserted into the insertion holes H1 and H2.

As described above, the operating section 10 is provided with a plurality of switches and a plurality of indicator lights, and is provided with monitoring displays necessary in the event of a fire, failure, and test. In some cases, the operation unit 10 may not be provided with a plurality of indicator lights.
Only a plurality of switches may be provided.

[0011] Furthermore, a mode in which fire or failure monitoring or testing is performed without installing the template T on the operation unit 10 is referred to as a monitoring state mode. On the other hand, the template T is provided with a setting display necessary for setting the predetermined control content, and a mode in which the template T is installed on the operation unit 10 and the predetermined control content is set is referred to as a control content setting mode. The predetermined control contents include automatic fire test cutoff, line-specific accumulation release, warning sound stop at on-site start-up, disconnection detection prohibition, forced ringing time, subsequent signal re-ringing, and interlocking control of controlled equipment such as smoke prevention equipment. etc.

In the monitoring status mode, a security guard or the like judges each status based on the display of various indicator lights on the operation unit 10 without using the template T. Respond to each situation by operating various switches. On the other hand, when performing various settings, a template T is installed on the operation unit 10, and necessary setting operations are performed by operating a switch corresponding to the display based on the display written on the template T. .

Note that when the template T is installed on the operating section 10, the protrusions T1 and T2 of the template T are attached to the operating section 1.
0 into the insertion holes H1 and H2, and at this time, the protrusion T
1 and T2 press the insertion detection switches SW1 and SW2, so a CPU (not shown) connected to the detection switches SW1 and SW2 determines that the template T is installed. Then, the CPU switches from the monitoring state mode to the control content setting mode. Therefore, the protrusions T1 and T2 of the template T and the insertion detection switch S
W1, SW2, and the CPU are examples of mode switching means that switches between the monitoring state mode and the control content setting mode.

Next, the operation of the above embodiment will be explained.

First, in the monitoring state mode for performing fire and maintenance inspections, there are three operations in the event of a fire, in the event of a failure, and in the event of a test, and these will be explained.

In the event of a fire, a fire detector (not shown) issues an alarm, the fire receiver 1 receives a fire signal, the corresponding district light 21 lights up to indicate the fire area, and the smoke prevention equipment is activated. The main sound and the district sound of the relevant area are sounded, the main sound is sounded to call the staff, and the smoke prevention equipment is activated and the operation signal is transmitted. The anti-smoke response lamp 22 lights up upon receiving this signal. The staff member then presses the ``main sound stop'' switch and goes straight to the fire area to confirm the fire. At this time, if it is a false alarm, return to the fire receiver 1 and press the "district sound stop" switch and the "fire recovery" switch.

On the other hand, in the event of a malfunction such as a blown fuse, a dead battery, abnormal circuit voltage, abnormal electrical transmission within the panel, abnormal EEPROM, or malfunction of smoke prevention equipment, a warning sound will sound and indicator light 1 will be activated.
2 “Failure” light comes on.

When performing a test using the operating section 10, the "manual fire test" switch and the "automatic fire test" switch are operated. The "fire manual test" switch is a switch for performing a functional test of the fire receiver 1. By pressing this switch, the external line is cut off, and a dummy line is connected to the line of the number selected by pressing the number setting switch 14. You can input and check the fire signal. The "Fire automatic test" switch is used for the same purpose as the "Fire manual test" switch. After turning on the "Fire manual test" switch, if you press the "Fire automatic test" switch, the lines will be checked sequentially from 1 to the last line. Sent automatically.

Next, the operation when entering the control content setting mode using template T and setting predetermined control content will be described.

First, in order to switch from the monitoring state mode to the control content setting mode, template T may be set on the operating section 10.

FIG. 5 shows the template T set in the operating section 10, and the window portion of the template T is shown with broken lines to clearly show it.

By setting the template T in the operation section 10 in this way, each switch performs an operation according to the display described in the template T.

For example, when the "fire automatic test cutoff" switch is pressed, the interlocking output to external equipment is cut off during the test. In addition, external equipment that is linked in the event of a fire (fire hydrant pump,
If you do not want the external equipment (smoke prevention equipment, etc.) to be interlocked during the test, press the "Fire automatic test cutoff" switch to cut off the interlocking of external equipment during the test, and each time you press that switch, the cutoff state setting/ Releases alternate.

The "cancel accumulation by line" switch is a switch for canceling and setting accumulation for each line. The line-specific storage release function is useful when there is a line in which only a sensor or heat sensor with a storage function is connected to a receiver with a storage function, or when an early warning is required even if there is a false alarm. . When canceling accumulation by line, the number setting switch 14 is used to display the line number on the number display section 13. In this case, two-digit line selection is performed using two switches, a switch for the 1st position and a switch for the 10th position. For example, assume that the 12th line is selected. Then press the "Cancel accumulation by line" switch (each time you press it, the cancellation of accumulation/setting changes alternately)
. As a result, the indicator light "10" in the line number display window W4 lights up, and the indicator light "2" in the line number display window W5 lights up, indicating that the 12th line has been released from storage. is displayed.

[0025] The "Caution sound stop when starting on-site" switch turns off the warning sound that is emitted to notify the receiver 1 when smoke prevention equipment is started manually or for some reason on-site. Suspension can be set or canceled for each line. Specifically, number setting switch 1
4 to display the line number on the number display section 13, and then press the "Caution sound stop when starting on-site" switch (
(Each time you press this button, the setting/cancellation of the warning sound toggle alternates.)

When the "disconnection detection prohibition" switch is pressed, the operation for detecting line disconnection is disabled. In other words,
If an empty line of receiver 1 is left as it is, a disconnection will be detected and an error message will be displayed.In order to prevent an error message from being displayed for an empty line, conventionally, a terminating resistor is connected to each idle line. However, by using this switch, disconnection detection is not performed, so there is no need to connect a terminating resistor. Specifically, number setting switch 1
4 to display the desired line number on the number display section 13, and press the "Disconnection Detection Prohibition" switch (in this case, each time the switch is pressed, the setting/cancellation of the Disconnection Detection Prohibition alternates).

[0027] The "forced ringing time" switch is for forcibly ringing the district sound which is set to the ringing stop state, and the main sound ringing of the receiver 1 due to the detection signal of the sensor has elapsed for a predetermined period of time. If the system does not stop the system, it assumes that the person in charge is not present, and forcibly activates the local sound system. In order to prevent the district sound from ringing due to false alarms from fire detectors, "district sound stop" is sometimes applied all the time, but if you use the "forced ringing time" switch to set a predetermined time for the main sound to sound, the main sound can be stopped. If the sound continues for a predetermined period of time without being stopped, the district sound will be forced to sound. When setting the forced ringing time, the number setting switch 14 displays the set time in minutes and 10 seconds on the number display section 13. Then, if you press the "forced ring time" switch, the ring will ring after the set time. Note that if you want to cancel the forced ringing time, you can display "00".

[0028] The "successive signal re-sound" switch causes the fire receiver 1 to detect a certain failure and sound the warning sound, and then also when the fire receiver 1 detects another failure to sound the warning sound. This is a switch for The receiver 1 constantly monitors a plurality of types of failures, and when a failure is detected, it sounds a warning signal to notify an attendant, who then presses a "caution sound stop" switch to investigate the failure. At this time, normally the receiver 1 will not ring even if it detects another failure, but
When the "successive signal re-sound" switch is pressed, even if the fire receiver 1 detects another failure, a warning sound will be sounded in response to this subsequent failure signal. In addition, each time you press the "Subsequent signal re-sound" switch, the re-sound setting/
The cancellation is made.

[0029] In addition, if there is an interlocking control table for controlled equipment such as smoke prevention equipment that is interlocked with the fire signal line, the interlocking operation can be performed in the same manner as above using a specific switch and the number setting switch 14. Control is set/cancelled.

In the above embodiment, the indicator light 12 is used as a "common indicator light", but the indicator light 12 may be replaced by a district light 21 or a smoke prevention response light 22.

In the above embodiment, when switching from the monitoring state mode to the control content setting mode, the protrusions T1 and T2 of the template T and the insertion detection switch SW1
, SW2 are used, but a password may be input instead.

FIG. 6 is a diagram showing a template Ta when a password is input as the mode switching means.

That is, for example, press the "reset" switch twice, use the 10th and 1st position switches of the number setting switch 14 to input the first two digits of the password, and
Press the "Settings" switch, enter the next two digits in the same way as above, and press the "Settings" switch. 4 entered like this
When the digit code matches a preset number, the monitoring state mode is switched to the control content setting mode based on the judgment of a CPU (not shown) or the like. Conversely, when switching from the control content setting mode to the monitoring state mode, the "reset" switch can be pressed twice in succession.

According to the above embodiment, since the number of switches on the panel is small, the space required for the operation section 10 can be reduced, and not only is manufacturing easier, but there are also fewer unnecessary switches, so there is no risk of fire. When an instant operation is required at any time, the instant operation can be performed easily and without error. In addition, the switch function for setting control contents, which is not used except when installing equipment or changing room partitions, is always hidden, so it is less likely to be operated by mistake or tampered with.

[0035] Furthermore, if a template T is used, the mode is switched at the same time as the template T is installed, so preparation for control content settings can be done with a single touch, and you can also see at a glance which mode it is currently in. There is no risk of incorrect operation. In addition, when entering a PIN code as a means of mode switching, the switch function for setting control details, which is rarely used except when installing equipment, is usually hidden because it can only be accessed by the person concerned. ,
There is less risk of misoperation or tampering.

Furthermore, in the above embodiment, the operation section 10 includes:
Monitoring displays necessary in the event of fire, failure, and testing are provided, and template T includes setting displays necessary when setting the specified control contents, but displays other than monitoring displays and setting displays are provided. may be performed separately.

Furthermore, the function of the switch after changing the mode may not be displayed at all, and the person concerned may operate it while referring to a dedicated manual.

Furthermore, after switching from the monitoring state mode to the control content setting mode, the normal monitoring state mode may be automatically returned to after a predetermined period of time, such as 5 minutes or 10 minutes. In this way, it is possible to eliminate the negative effects caused by forgetting to switch the mode. Furthermore, after switching to the control content setting mode, the mode may be automatically returned to the normal monitoring state mode after a predetermined period of time has elapsed since the last setting operation.

In the above embodiment, only the case of switching between two modes is explained, but it is possible to switch between three or more modes by dividing them by purpose, frequency of use, importance, etc. Good too.

For example, it may be possible to switch between the monitoring mode, the first control content setting mode, and the second control content setting mode. In this case, the first control content setting mode is a mode in which there are relatively few problems even if there are incorrect settings such as "fire automatic test cutoff" or "caution sound stop at on-site startup", and the second control content setting mode The setting mode is a mode in which incorrect settings such as "disconnection detection prohibited" or "interlocked control of controlled equipment" may cause problems.

[0041] Furthermore, a changeover switch provided within the panel or a dedicated key may be used as the mode switching means.

[0042]

[Effects of the Invention] According to the present invention, when it is necessary to arrange both a monitoring switch necessary for monitoring in the event of a fire, a failure, a test, etc. and a switch for setting control contents, a fire receiver, etc. The space required for the operating section can be reduced, and furthermore, when it is necessary to perform an immediate operation such as when a fire breaks out, it is possible to make the immediate operation easier.
