Description

This invention also relates to the transfer paper output unit in the alarm system.

  For example, as an example of a wireless alarm system, a fire alarm can be linked (notified) by transmitting and receiving a signal related to a fire as an example of an environmental abnormality between a plurality of fire alarms. A wireless fire alarm system is disclosed (for example, see Patent Document 1).

  In recent years, there has been a desire to alert and notify the state of the fire alarm system in an easy-to-understand manner by accurately outputting predetermined event information (for example, a fire radio signal) from the fire alarm system to an external device (external system). There is.

  Therefore, unlike a fire alarm, it does not have a fire detection function, but when it receives a warning signal, it sends it to an external device. It is conceivable to provide an adapter and a fire alarm repeater in the system. Here, examples of the external device (external system) include a housing information board (interphone system) and a flashlight device.

  In the above-mentioned fire alarm system, for example, inspection, installation work, cooking, etc., even if smoke that is not known to be a fire in advance (non-fire) has occurred (becomes a false alarm), a transfer signal is output. Then, it may be transferred to an external device. For this reason, although it is not actually a fire, there are cases where it is annoying to the user, such as voice output from a door phone, blinking of a light, and the like.

Therefore, an object of the present invention is to obtain a message output device that can improve the convenience for the user.

The transfer output device of the present invention is a relay output unit that outputs a transfer signal based on a radio signal in order to relay between an alarm system having an alarm device capable of transmitting and receiving a radio signal and an external device, the Utsuriho signal based on the radio signal for causing an alarm interlocked with the equipment in the system, and e Bei and Utsuriho cutoff setting means for setting the Utsuriho blockade so as not to output from the transfer paper output section The message output setting unit has a function for setting the message blocking function valid or invalid, and when the message blocking function is set to be effective by the message blocking setting means. When the transfer signal is not output from the transfer output unit and the transfer blocking function is set to be effective, the first notification for notifying that the message transfer is being interrupted and interlocked during the transfer blocking. Notify that a radio signal has been received to alert you And a different second notification to the first notification, and performs the same transfer paper output device.

  Further, the message blocking setting means of the message output device of the present invention has a message blocking function setting switch for setting the message blocking function to be valid or invalid, and the message blocking function is set by the message blocking function setting switch. When it is set to be valid, a message output signal is not output from the message output unit.

  In addition, the message interruption setting means of the message output device of the present invention includes a message interruption function setting switch for setting the validity of the message interruption function and a message interruption start switch for instructing the start of message interruption. When the message blocking function is enabled by the message blocking function setting switch, the timer starts counting when the message blocking start switch is operated, and the message is output for a maximum period of time. This prevents the transfer signal from being output from the unit.

  Further, the message output device of the present invention receives a radio signal for operating a message interrupt start switch again during message interrupt or to cause an alarm linked to two or more different devices in the system. Or, when a certain time elapses, the message blocking is canceled.

In addition, the message transfer function setting switch of the message output device of the present invention also serves as a switch for setting a message output check function for checking whether or not a message signal can be output , When the message blocking function is enabled by the message blocking function setting switch, the message output inspection function is disabled, and when the message blocking function is disabled by the message blocking function setting switch. The transfer output check function is enabled, the transfer cutoff start switch functions as a transfer output check switch, and when the transfer output check switch is operated, a transfer signal is output from the transfer output unit. Is.

  Further, the alarm system of the present invention is an alarm operation in which one or a plurality of alarm devices for detecting environmental abnormalities and one or a plurality of transfer output devices as described above are linked by transmitting and receiving radio signals. It is comprised so that it can perform.

According to the present invention, since the setting related to the message blocking not to output the message signal to the message output unit can be performed by the message blocking setting means, it is not an environmental abnormality in advance, for example, a non-fire. If the message is known (assumed), it is not necessary to operate the external device in an interlocked manner by blocking the transfer, and convenience can be improved.
Also, a first notification for notifying that the message transfer is being interrupted and a second notification for notifying that a radio signal for causing an alarm linked to the notification being interrupted is received. Thus, it can be performed while distinguishing each notification that it is in the message transfer interrupted state and that another device is performing an environmental abnormality, for example, an alarm relating to a fire.

  Also, when the message blocking function is enabled by the message blocking function setting switch, the message output signal is not output to the message output unit, so the message is not always output to an external device. This is useful when you want to deal with

  In addition, when the message blocking start switch is operated, the timing of the predetermined time (fixed time) for stopping the message is started and the message blocking is performed for the predetermined time. It is possible to cut off a message.

  In addition, when the message blocking start switch is operated again during message blocking or a radio signal for performing the linked alarm is received from two or more different devices in the system, or when a predetermined time elapses Since the transfer blocking is canceled, it is possible to quickly cope with the need to transfer to an external device.

  And since the above-mentioned transfer output device was systemized with the alarm device, a highly convenient alarm system can be obtained.

In addition, when an alarm signal (interlocking control signal) relating to a fire is received from another fire alarm device 10 in the group, an alarm is interlocked.

  In addition, the repeater 30 is a device that performs relay when communicating with an external device in order to transfer (output) an alarm signal related to the fire of the fire alarm system to an external device (including an external system). is there. Similarly to the fire alarm 10, a unique address is set for the repeater 30 and is treated as a child device in communication. Here, the repeater 30 of the present embodiment does not have a function of detecting a fire or the like, but can perform an alarm in conjunction with the interlock control signal from the fire alarm 10 or the like. And

  FIG. 2 is a diagram for illustrating a circuit configuration and the like of the fire alarm device 10 according to the first embodiment. In FIG. 2, a fire alarm 10 includes a control circuit 1, a battery 2, a power supply circuit 3, a battery voltage detection circuit 4, a transmission / reception circuit 5, an antenna 6, and a fire detection circuit as an example of an abnormality detection circuit that detects an environmental abnormality. 7. An alarm sound control circuit 8, a display circuit 9, and an alarm stop switch 20 are provided.

  The control circuit 1 performs processing based on an input signal or the like, and controls a circuit or the like included in the fire alarm 10. For example, on the basis of a signal from the fire detection circuit 7, the alarm sound control circuit 8 and the display circuit 9 are operated to perform an alarm relating to fire by sound and display. Communication processing with other devices in the system (group) is performed via the transmission / reception circuit 5. The memory element 21 included in the control circuit 1 is a non-volatile memory such as an EEPROM, for example, a program related to processing executed by the control circuit 1, addresses set in itself and other devices in the group, a group of groups to which the group belongs Various data such as IDs are stored.

  The battery 2 supplies DC power to the power supply circuit 3. The power supply circuit 3 controls the voltage of the battery 2 to a predetermined voltage and supplies it to each circuit of the fire alarm 10. The battery voltage detection circuit 4 detects a voltage related to the application of the battery 2 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 1.

  When it is determined that the remaining battery level is low or the battery depletion threshold value is exceeded based on the voltage detection signal from the battery voltage detection circuit 4, the control circuit 1 drives the alarm sound control circuit 8 and the display circuit 9. To let you know when the battery is dead.

  The transmission / reception circuit 5 is connected to an antenna 6 for transmitting / receiving a radio signal, processes a radio signal input (sent) via the antenna 6, and includes its own address as communication destination data. If it is determined that all addresses are included as communication destinations, reception processing is performed. In addition, the transmission / reception circuit 5 performs transmission processing of a state signal and the like related to processing of the control circuit 1.

  The fire detection circuit 7 detects a physical change such as smoke or heat based on the fire phenomenon and outputs a signal corresponding to the detected content to the control circuit 1. Here, it demonstrates as what outputs the signal which concerns on the detection of fire, without distinguishing in particular in detail.

  The alarm sound control circuit 8 is a circuit for controlling an operation for generating an alarm sound or the like from a buzzer / speaker or the like (sound generation means, notification means, not shown). The display circuit 9 is a circuit that controls the lighting operation of an indicator lamp such as a light emitting diode (display means, notification means, not shown). Here, the description will be made assuming that the circuit is a circuit that controls the lighting of the indicator lamp. However, for example, when a display unit that can display characters, numbers, and the like is provided, the display of characters and the like may be controlled. . It is assumed that the alarm stop switch 20 serving as an instruction input unit also serves as a switch for a user to stop an alarm relating to a fire at the time of an alarm relating to a fire.

  FIG. 3 is a diagram for illustrating a circuit configuration and the like of the repeater 30 according to the first embodiment. 3, the repeater 30 includes a control circuit 31, a battery 32, a power supply circuit 33, a battery voltage detection circuit 34, a transmission / reception circuit 35, an antenna 36, an alarm sound control circuit 38, a display circuit 39, and an inspection / alarm stop switch 41. Prepare.

  The control circuit 31 performs processing based on an input signal or the like, and controls a circuit or the like included in the repeater 30. For example, based on an alarm signal from the fire alarm device 10, the alarm sound control circuit 38 and the display circuit 39 are operated to give a fire alarm or the like by sound and display. Further, communication processing with other devices in the system (group) is performed via the transmission / reception circuit 35. The storage element 44 is a non-volatile memory such as an EEPROM, for example, and various data such as a program related to processing executed by the control circuit 31, addresses set for itself and other devices in the group, and group ID of the group to which the storage element 44 belongs. Is stored. In the present embodiment, the control circuit 31 has a timer 45 for measuring time.

  The battery 32 supplies DC power to the power supply circuit 33. The power supply circuit 33 controls the voltage of the battery 32 to a predetermined voltage and supplies it to each circuit of the repeater 30. The battery voltage detection circuit 34 detects a voltage related to the application of the battery 32 and outputs a battery voltage detection signal to the control circuit 31. Based on the battery voltage detection signal, the control circuit 31 drives the alarm sound control circuit 38 and the display circuit 39 to notify the battery exhaustion or the like.

  The transmission / reception circuit 35 processes a radio signal input (sent) via an antenna 36 for transmitting / receiving a radio signal, and includes its own address as communication destination data (all communication destinations are all communication destinations). If it is determined that the address is included), reception processing is performed. If it is determined that the radio signal is other than its own address, the reception process is not performed. The received signal is output to the control circuit 31. In addition, the transmission / reception circuit 35 performs transmission processing of a state signal and the like related to the processing of the control circuit 31.

  The alarm sound control circuit 38 is a circuit for controlling an operation for generating an alarm sound from a buzzer / speaker or the like (sound generation means, notification means, not shown). The display circuit 39 is a circuit that controls the lighting operation of an indicator lamp (display means, notification means, not shown) such as a light emitting diode. For example, when the repeater 30 has a display unit that can display characters, numbers, and the like, control for displaying characters and the like may be performed.

  The inspection / alarm stop switch 41 serving as an instruction input unit is, for example, a button-type switch for a user to stop an alarm relating to a fire at the time of an alarm relating to a fire. Here, the inspection / alarm stop switch 41 can be selectively used by distinguishing, for example, half-pressing, full-pressing, short-pressing or long-pressing. In particular, in the present embodiment, for example, when the user performs a long press operation for 2 seconds or more, a transition for preventing the transmission output signal from being output from the transmission output unit 40 for a certain time (predetermined time). It shall be able to function as an information cutoff start switch. In addition, as will be described later, in order to check whether or not a transfer signal can be output, the transfer output unit 40 can function as a transfer output check switch that outputs a transfer signal.

  Further, the repeater 30 of the present embodiment further includes a message output unit 40, an alarm stop signal transmission setting switch 42, and a message interrupt function setting switch 43. The transfer output unit 40 outputs (transmits) a transfer signal including an alarm signal related to a fire to an external device or the like outside the system. Here, in the present embodiment, the transfer output unit 40 is wired to an external device or the like, but may be wirelessly connected.

  Further, the alarm stop signal transmission setting switch 42 serving as an alarm stop signal transmission setting means determines whether or not to transmit an alarm stop signal to other devices when the inspection / alarm stop switch 41 is operated by the user. Is a switch (for example, setting means such as a dip switch). Here, for example, the setting change by the alarm stop signal transmission setting switch 42 of the present embodiment becomes effective when the power is turned on and reset by a reset button (not shown) or the like. For this reason, the setting is not changed even when the switch is switched at the normal time, but the setting may be changed at the normal time.

  A message transfer function setting switch 43 serving as a message interrupt function setting means is a switch for setting whether or not the inspection / alarm stop switch 41 functions as a message interrupt start switch. For example, in the present embodiment, the transfer interruption function setting switch 43 is also used as a switch that causes the inspection / alarm stop switch 41 to function as a transfer output inspection switch. For example, in the DIP switch, if the message blocking function is on, the message output checking function is turned off and the inspection / alarm stop switch 41 is made to function as a message blocking start switch. If the message shut-off function is off, the message output inspection function is turned on and the inspection / alarm stop switch 41 is caused to function as a message output inspection switch. Here, in the present embodiment, the message blocking function setting means is configured by a switch, but it is not particularly limited to the switch, for example, the setting made according to the request is stored in the storage element 44 as a database. . The same applies to the alarm stop signal transmission setting switch 42.

  For example, when it is known (presumed) that the environment is not abnormal (non-fire report) due to cooking or the like, a transfer signal is output from the repeater 30 to an external device. There are cases where it is not necessary to do so. Therefore, the repeater 30 in the fire alarm system according to the present embodiment can be set so as not to output a transfer signal to an external device. For this reason, in the repeater 30, the inspection / alarm stop switch 41 is caused to function as a message shut-off start switch that prevents the message output signal from being output from the message output unit 40. Then, a transfer interruption function setting switch 43 for setting the inspection / alarm stop switch 41 to function as the transfer interruption start switch is provided.

  In addition, the control circuit 31 operates the message interruption start switch so as not to output the message signal from the message output unit 40 for a certain period of time after determining that the message interruption start switch has been operated. When it is judged that it is a thing, it starts timing. Then, it is determined that the message transfer start switch has been operated again during the time measurement, or it is determined that the transmission / reception circuit 35 has received two or more interlocking control signals related to the fire including the alarm signal related to the first fire. If it is determined that a certain period of time has elapsed, the message blocking is canceled.

  FIG. 4 is a diagram illustrating a flowchart of alarm processing relating to a fire of the fire alarm device 10 according to the first embodiment. Here, based on FIG. 4, the alarm process which concerns on the fire which the control circuit 1 of the fire alarm device 10 performs is demonstrated.

  First, it is determined whether or not a signal is input from the fire detection circuit 7 (S1). If it is determined that a signal due to fire detection has been input, the place where it is installed becomes the fire alarm 10 of the fire source. Accordingly, the alarm sound control circuit 8 is operated to generate a sound or the like indicating that the fire is a fire, and the display circuit 9 is operated to display a fire source alarm for displaying the fire (S2). . Here, for the fire source alarm, the alarm sound control circuit 8 is operated to generate a sound such as “Pee, Hugh, Hugh, Fire, Fire”, and the display circuit 9 is operated, for example, displayed in red. Make the light blink. Then, the transmission / reception circuit 5 is caused to transmit an interlock control signal for interlocking the alarm to other devices in the group via the antenna 6 (S3).

  On the other hand, if it is determined in S1 that a fire detection signal is not input from the fire detection circuit 7, it is determined whether an interlock control signal is received from another device via the antenna 6 and the transmission / reception circuit 5 ( S4). If it is determined that the interlock control signal has been received, the alarm sound control circuit 8 is operated to generate a sound indicating a fire at another location, and the display circuit 9 is operated to display a fire. An interlocking alarm is performed (S5). Here, for the interlock alarm, the alarm sound control circuit 8 is operated to generate a sound such as “Pe, Hugh, Hugh, a fire in another place”, and the display circuit 9 is operated to display, for example, orange. Make the light blink. If it is determined that the interlock control signal has not been received, the process returns to S1, and determination of signal input from the fire detection circuit 7 and reception of the interlock control signal is performed at predetermined time intervals.

  Then, after giving an alarm, it is determined whether the alarm stop switch 20 is pressed and an instruction to stop the alarm is given (S6). If it is determined that the alarm stop switch 20 has been pressed, the sound generation by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, and the fire source alarm or the interlocking alarm is stopped (S7). Here, when the interlocking alarm is stopped, the generation of sound by the alarm sound control circuit 8 and the display by the display circuit 9 are both stopped. On the other hand, when the fire source alarm is stopped, the generation of sound by the alarm sound control circuit 8 is stopped, but the display circuit 9 continues to blink the indicator lamp. Then, the transmission / reception circuit 5 is caused to transmit an alarm stop signal for stopping alarms of other devices via the antenna 6 (S8), and the process returns to S1 and is performed again.

  If it is determined in S6 that the alarm stop switch 20 has not been pressed, it is determined whether an alarm stop signal has been received from another device via the antenna 6 and the transmission / reception circuit 5 (S9). If it is determined that the alarm stop signal has been received, the sound generation by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, the interlocking alarm is stopped (S10), and the process returns to S1 and the process is performed again. At this time, since only the interlocking alarm is stopped by the alarm stop signal, the fire alarm is not stopped in the fire alarm device 10 performing the fire alarm. If it is determined that an alarm stop signal from another device has not been received, the process returns to S6 and the alarm is continued until the alarm stop switch 20 is pressed or an alarm stop signal from another device is received.

  By performing the above processing, when the alarm stop switch 20 is pressed in the fire alarm device 10 related to the fire source alarm, the self fire source alarm and the interlocking alarm in other devices are stopped. On the other hand, when the alarm stop switch 20 is pressed in the fire alarm device 10 related to the interlocking alarm, the interlocking alarm in itself and other devices stops (the fire alarm does not stop).

  FIG. 5 is a diagram illustrating a flowchart of alarm processing relating to a fire of the repeater 30 according to the first embodiment. Next, based on FIG. 5, the alarm process regarding the fire which the control circuit 31 of the repeater 30 performs is demonstrated. Here, it is assumed that the repeater 30 is set not to shut off the transmission.

  First, it is determined whether an interlock control signal has been received from another fire alarm 10 or the like via the antenna 36 and the transmission / reception circuit 35 (S21). If it is determined that the interlock control signal has not been received, the determination of the interlock control signal reception is performed at predetermined time intervals.

  If it is determined that the interlock control signal has been received, the alarm sound control circuit 38 and the display circuit 39 are operated to cause the interlock alarm (S22). For the linked alarm, the alarm sound control circuit 38 is operated to generate a sound such as “Pee, Hugh, Hugh, Fire, Fire”, and the display circuit 39 is operated to blink the indicator light in orange, for example. Let In addition, the alarm output unit 40 outputs an alarm alarm signal related to the fire (S23).

  Then, it is determined whether the inspection / alarm stop switch 41 is pressed and an instruction to stop the alarm is given (S24). If it is determined that the inspection / alarm stop switch 41 has been pressed, it is further determined whether the alarm stop signal transmission setting switch 42 is set to transmit an alarm stop signal (S25). If it is determined that the transmission is set, the transmission / reception circuit 35 is caused to transmit an alarm stop signal for stopping the interlocking alarm of another device via the antenna 36 (S26). If it is set not to transmit, the alarm stop signal should not be transmitted.

  Then, the interlocking alarm is stopped (S27). Here, when the interlock alarm is stopped in the repeater 30, for example, the generation of sound by the alarm sound control circuit 38 is stopped, but the display circuit 39 keeps the blinking of the indicator lamp. Then, the transfer output unit 40 continuously outputs the alarm transfer signal for the fire (S28).

  On the other hand, if it is determined in S24 that the inspection / alarm stop switch 41 has not been pressed, it is determined whether an alarm stop signal from another device has been received via the antenna 36 and the transmission / reception circuit 35 (S29). If it is determined that the alarm stop signal has been received, it is determined whether or not the signal transmission source is the fire alarm device 10 related to the fire source, based on the received alarm stop signal (S30). If it is determined that the fire alarm 10 is related to the fire source, the interlocking alarm is stopped (S31). Here, in the case of an alarm stop signal from the fire alarm 10 relating to the fire source, both the generation of sound by the alarm sound control circuit 38 and the display by the display circuit 39 are stopped. And the transfer output part 40 stops the output of the signal which concerns on a fire alarm (S32), returns to S21, and performs a process again. If it is determined that it is not the fire alarm device 10 related to the fire source, the generation of sound by the alarm sound control circuit 38 is stopped, but the display circuit 39 continues to blink the indicator lamp (S27). Then, the transfer output unit 40 continuously outputs the alarm transfer signal for the fire (S28).

  FIG. 6 is a diagram mainly illustrating processing of the control circuit 31 related to the message transfer interruption function. First, when it is determined that the inspection / alarm stop switch 41 is pressed (long pressed) for 2 seconds or more by the user (S41), the message blocking function is turned on (enabled) in the message blocking function setting switch 43. It is determined whether or not there is (S42). Here, when it is determined to be off (invalid), processing related to the transfer output check function is performed.

  With regard to the transfer output check function, the alarm sound control circuit 38 is operated to generate a sound or the like during the transfer output check, and the display circuit 39 is operated to display a transfer output check alarm (this embodiment). In step S61, an alarm similar to the interlocking alarm) is performed. Moreover, the process which makes the report output part 40 output the report signal concerning a report output inspection warning is performed (S62), and it complete | finishes.

  On the other hand, when it is determined that the message blocking function is on, the timer 45 starts measuring time (S43). Then, the display circuit 39 is operated to display (first notification) indicating that it is in the message blocking state (S44). For the display, the indicator lamp blinks twice in red and is periodically performed.

  And it is judged whether the interlocking control signal was received via the antenna 36 and the transmission / reception circuit 35 (S45). If it is determined that the interlock control signal has been received, it is determined whether it is the first interlock control signal (S46). If it is determined that it is the first interlocking control signal, an interlocking alarm (second notification) in the transfer interruption state is performed (S47). Here, for the interlocking alarm in the transfer interruption state, the display circuit 39 is operated, the indicator lamp blinks twice in orange, and this is periodically performed.

  If it is determined that it is not the first interlock control signal, it is determined whether it is an interlock control signal from a device other than the device that transmitted the first interlock control signal (S48).

  If it is determined in S45 that no interlocking control signal has been received or it is not a interlocking control signal from another device in S48, it is determined whether or not a fixed time has elapsed since the timer 45 started counting (S49). Here, in this embodiment, the fixed time is set to 1 hour. If it is determined that the predetermined time has not elapsed, it is determined whether or not the inspection / alarm stop switch 41 is pressed again for a long time (S50). If it is determined that the inspection / alarm stop switch 41 has not been pressed for a long time, it is determined whether an alarm stop signal has been received from another device via the antenna 36 and the transmission / reception circuit 35 (S51). If it is determined that the alarm stop signal has not been received, the process returns to S45 to continue the processing. If it is determined that the alarm stop signal has been received, the process returns to S44 to return to the display indicating that the message transfer is interrupted, and the process is continued.

  When it is determined in S48 that a predetermined time has elapsed since the start of timing in S49, or the inspection / alarm stop switch 41 is pressed again for a long time in S49, which is an interlocking control signal from another device, the message blocking state is canceled. (S52), and the process ends. If it is determined that the interlock control signal has been received from the other fire alarm device 10 or the like via the antenna 36 and the transmission / reception circuit 35 after the processing is completed, the alarm processing described above is performed.

  As described above, according to the repeater 30 in the system according to the first embodiment, the message blocking function is set by the message blocking function setting switch 43, for example, when the user presses the inspection / alarm stop switch 41, Since it is possible to shut off the signal without outputting it to the message output unit 40 for a certain period of time, if it is known in advance that it is non-fire (presumed), the message is shut off. By doing so, it is not necessary to operate external devices in conjunction with each other, so that convenience can be improved.

  Since the inspection / alarm stop switch 41 is made to function as a transmission interruption start switch, and the timing of the fixed time for performing the transmission interruption is started by pressing the user, the transmission interruption is performed at the set time. be able to.

  In addition, the message blocking function setting switch 43 can also be used as a switch for setting the message output inspection function by switching, so that the number of switches can be simplified and the cost can be reduced while expanding the functions. Reduction, prevention of malfunction, etc. can be achieved.

  Further, the control circuit 31 determines that the message transfer start switch has been operated again during the time measurement, or has determined that the interlock control signal has been received from two or more different devices, or a certain time has elapsed. If it is determined that the message blocking is canceled, it is possible to quickly cope with the need to transfer information to an external device.

  Further, when the inspection / alarm stop switch 41 (transmission cutoff start switch) is pressed, the control circuit 31 operates the display circuit 39 to display on the display means that the transmission cutoff state is indicated. Since the first notification is made to be performed, the user can be notified (teached) that it is in the transfer blocking state. In addition, when the first interlock control signal is received, the interlock alarm (second alarm) in the message transfer interruption state is performed, so that other equipment is performing alarms related to fire, etc. It is possible to notify the user in distinction from the first notification.

  And the above-mentioned repeater 30 is comprised as a system with the fire alarm device 10, and a highly convenient fire alarm system can be obtained.

For example, a separate dip switch for setting the transfer output inspection function may be provided, and the ON / OFF of each function may be set by two dip switches.

Embodiment 3 FIG.
In the above-described embodiment, the transfer interruption function setting switch 43 is a switch for causing the inspection / alarm stop switch 41 to function as a transfer interruption start switch. For example, while the message blocking function setting switch 43 is set to ON, the message is always output in response to the interlock control signal from another device regardless of whether the inspection / alarm stop switch 41 is pressed. It may be a switch for setting so as not to output the transfer signal from the unit 40. For example, when the installation location of the system changes to an environment where non-fire smoke is likely to occur (prone to false alarms), only the sound and display of the repeater 30 is performed and a transfer signal is output to an external device. This is useful when you want to deal with it.

  Further, the message blocking setting unit may be configured by only the message blocking start switch (inspection / alarm stop switch 41) without providing the message blocking function setting switch 43. In this case, for example, when the message blocking start switch is pressed by a long press operation, the message blocking setting becomes effective, and starts counting time for a certain period of time when message blocking is performed. Try to shut off.

  Further, the storage element 44 stores, for example, 1 hour as a fixed period as a period during which the transfer signal is not output from the transfer output unit 40 based on the time measured by the timer 45. Other fixed periods may be stored.

  In all the embodiments described above, the fire alarm system including the fire alarm device 10 and the relay device 30 has been described. However, the present invention is not limited to a fire and detects other environmental abnormalities such as gas leakage. The present invention can also be applied to an alarm system including an alarm device and a repeater 30.
