  • the fire detecting unit 2 transmits an electrical signal (detection signal), indicating a voltage level corresponding to the quantity of the light received by the photodetector unit 22, to the control unit 10.
  • the control unit 10 determines, by converting the quantity of light represented by the detection signal received from the fire detecting unit 2 into the concentration of smoke (as an exemplary event level), whether or not any fire is present.
  • the fire detecting unit 2 may convert the quantity of the light received by the photodetector unit 22 into a smoke concentration and then transmit a detection signal indicating a voltage level corresponding to the smoke concentration to the control unit 10.
  • the fire detecting unit 2 may determine, based on the quantity of the light received at the photodetector unit 22, that a fire (smoke) should be present and then transmit a detection signal, including information about the outbreak of the fire, to the control unit 10.
  • the control unit 10 may be implemented as, for example, a microcomputer including, as major constituent elements, a central processing unit (CPU) and a memory. That is to say, the control unit 10 is implemented as a computer including a CPU and a memory. The computer performs the function of the control unit 10 by making the CPU execute a program stored in the memory. In this embodiment, the program is stored in advance in the memory. However, this is only an example and should not be construed as limiting. The program may also be downloaded via a telecommunications network such as the Internet or distributed after having been stored in a non-transitory storage medium such as a memory card.
  • a telecommunications network such as the Internet
  • a non-transitory storage medium such as a memory card.
  • the control unit 10 controls the first emission unit 11, the audio circuit, the second emission unit 12, the indicating lamp 15, the first lighting circuit, the second lighting circuit, the fire detecting unit 2, the apparatus detecting unit 6, the storage section 7 and other units.
  • the control unit 10 also controls a power supply circuit for generating, based on the DC power supplied from the battery 13, operating power for various types of circuits.

  • the storage section 7 may be a memory of the control unit 10 itself.
  • the control unit 10 is configured to determine, in accordance with information (the second information) provided about a fire from the fire detecting unit 2, whether or not any fire is present. The determination as to whether or not any fire is present will be described in detail below.
  • the control unit 10 monitors the level of the detection signal (information) received from the fire detecting unit 2 to determine whether or not the event level included in the detection signal has exceeded a threshold value.
  • the event level is, for example, smoke concentration after conversion as described above. Alternatively, the event level may also be the quantity of light.
  • the control unit 10 stores the threshold value in the storage section 7 or its own memory.
  • the control unit 10 may determine, at regular time intervals, whether or not the smoke concentration has exceeded the threshold value, and may determine, when finding the smoke concentration greater than the threshold value at least once, that a fire should be present.
  • the predetermined time interval is, for example, 5 seconds.
  • the control unit 10 may count the number of times the smoke concentration has exceeded the threshold value consecutively, and may determine, on finding the number of times reaching a predetermined number of times, that a fire should be present.
  • the control unit 10 may directly determine, on receiving a detection signal including information about the outbreak of a fire from the fire detecting unit 2, that a fire should be present.
  • the control unit 10 On determining, based on the smoke concentration, that a fire should be present, the control unit 10 makes the first emission unit 11 start emitting an alarm sound. Specifically, the control unit 10 generates a PWM signal corresponding to a sweep sound, of which the frequency changes linearly with the passage of time, and outputs the PWM signal to the audio circuit. The PWM signal is converted by the audio circuit into an audio signal so that a sweep sound (as an alarm sound) is emitted from the first emission unit 11. In addition, the control unit 10 also generates, based on message data stored in the storage section 7 or its own memory, a PWM signal corresponding to the voice warning message and outputs the PWM signal to the audio circuit. The PWM signal is converted by the audio circuit into an audio signal so that a voice warning message (with an alarm sound) is emitted from the first emission unit 11.
  • the control unit 10 transmits a control signal for flickering the indicating lamp 15 to the first lighting circuit, and a control signal for turning ON the second emission unit 12 to the second lighting circuit.
  • the first lighting circuit causes the indicating lamp 15 to perform the actuation flickering.
  • the second lighting circuit turns ON the second emission unit 12 with a certain level of brightness.
  • the control unit 10 also continues determining the smoke concentration even while the fire alarm is being sounded (i.e., while an alarm sound is being emitted).
  • the control unit 10 stops generating the PWM signal to instruct the first emission unit 11 to stop emitting the alarm sound.
  • the control unit 10 also transmits a stop signal to the first lighting circuit and the second lighting circuit to stop emitting light from the second emission unit 12 and the indicating lamp 15. That is to say, on determining that the fire (smoke) should be no longer present, the control unit 10 automatically stops emitting the alarm sound, stops emitting the illuminating light, and stops flickering the indicating lamp 15.
  • the control unit 10 stops emitting the alarm sound. If the resident 100 determines that the alarm should be being sounded by the alarm 1 by mistake, then he or she may stop emitting the alarm sound by performing the push operation on the operating unit 3. Emitting the alarm sound may also be stopped by the resident 100 pulling the pull string.
  • the control unit 10 carries out a predetermined type of test to check the operation.
  • the operation check test includes, for example, a sound emission test on the first emission unit 11, a light emission test on the second emission unit 12, and a flickering light test on the indicating lamp 15.
  • the operation check test may also be performed by pulling the pull string.
  • control unit 10 is configured to receive information (the first information) relating to the internal event from the apparatus detecting unit 6 to determine the presence or absence of the internal event. The determination as to the presence or absence of the internal event will be described in detail below.
  • the control unit 10 monitors the used hours received from the first sensor 61.
  • the used hours correspond to, for example, hours for which power supply is ON and the alarm 1 is in an operating state.
  • the control unit 10 accumulates and stores the used hours received from the first sensor 61 in the storage section 7 or in its memory.
  • the control unit 10 determines that it is the time for replacement when accumulated used hours amount to 10 years, and the control unit 10 causes the indicating lamp 15 which is the alert unit 8 to issue an alert. That is, the indicating lamp 15 starts performing the alert flickering.
  • the time for replacement is low in emergency level as compared to the battery exhaustion and the failure, and replacement of the alarm 1 depends on the availability of the resident 100. Therefore, the control unit 10 does not cause the first emission unit 11 to emit a voice warning message for notification of the time for replacement immediately after the determination, but only when the resident 100 gives a push operation to the operating unit 3 during the alert flickering.
  • the control unit 10 determines that the failure is present, the control unit 10 causes the first emission unit 11 and the indicating lamp 15 which are the alert units 8 to issue an alert. That is, a voice warning message for notification of the failure is emitted from the first emission unit 11, and the indicating lamp 15 starts performing the alert flickering. Note that in the case of breakage of a wire between the audio circuit and the first emission unit 11, issuing an alert from the first emission unit 11 is impossible, and therefore, an alert is issued only from the indicating lamp 15.
  • the control unit 10 monitors information which is about the battery voltage of the battery 13 and which is received from the third sensor 63.
  • the control unit 10 stores characteristic data including the battery voltage and the capacity of the battery 13 associated with each other in the storage section 7 or its memory in advance, and when a residual capacity corresponding to the battery voltage received is less than 10% of the capacity, the control unit 10 determines that the battery is exhausted.
  • the control unit 10 causes the first emission unit 11 and the indicating lamp 15 which are the alert units 8 to issue an alert. That is, the first emission unit 11 emits a voice warning message for notification of the battery exhaustion, and the indicating lamp 15 starts performing the alert flickering.
  • the control unit 10 determines the presence or absence of the internal event at a predetermined period.
  • the determination as to the internal event is performed, for example, once a day at 0:00.
  • the control unit 10 interrupts issuance of the alert concerning the event corresponding to the higher priority rank, allows an interruption by the alert concerning the event corresponding to the lower priority rank, and issues the alert concerning the event corresponding to the higher priority rank.
  • the control unit 10 when determining that an internal event occurs, stores an occurrence flag in the storage section 7.
  • the storage section 7 includes storage areas of respective three occurrence flags corresponding to, for example, the time for replacement, the failure, and the battery exhaustion.
  • the control unit 10 determines that it is the time for replacement, the control unit 10 writes an occurrence flag "1" to "0" in the storage area corresponding to the time for replacement.
  • the occurrence flag in the storage section 7 is erased ("1" is rewritten to "0") when the alert response to the internal event ends.
  • the situation in which "the alert response to the internal event ends" is, for example, a situation in which the battery 13 is replaced and a situation in which breakage of a wire is repaired.
  • control unit 10 since the control unit 10 is alarming about the presence of the "fire” corresponding to the highest rank A, the control unit 10 foregoes issuance of the alert concerning the occurrence of the "battery exhaustion", stores only the occurrence flag of the "battery exhaustion” in the storage section 7 (step S4), and causes the alert to enter the standby state.
  • control unit 10 subsequently determines that it is also the "time for replacement” during the emission of the alarm sound (step S5). However, since the control unit 10 is alarming about the presence of the "fire” corresponding to the highest rank A, the control unit 10 foregoes issuance of the alert concerning that it is the "time for replacement", stores only the occurrence flag of the "time for replacement” in the storage section 7 (step S6), and causes the alert to enter the standby state.
  • the control unit 10 ends the alert response to the "battery exhaustion” and erases the occurrence flag of the "battery exhaustion” (step S11).
  • the occurrence flag of the "time for replacement” is present in the storage section 7, and therefore, the control unit 10 starts issuing the alert concerning the time for replacement (step S12).
  • the "time for replacement” is less urgent, only the alert flickering of the indicating lamp 15 starts, and only when an operation is given to the operating unit 3 flickering in red, a voice warning message is emitted. Note that also regarding to the alert concerning the "battery exhaustion", only the alert flickering of the indicating lamp 15 starts, and only when an operation is given to the operating unit 3, a voice warning message may be output.
  • step S21 When the control unit 10 determines that the "battery exhaustion" occurs (step S21), the control unit 10 starts issuing the alert concerning the "battery exhaustion” (step S22) and stores the occurrence flag of the "battery exhaustion” in the storage section 7 (step S23). It is assumed that the control unit 10 determines that it is also the "time for replacement” during the issuance of the alert concerning the "battery exhaustion” (step S24).
  • the alert concerning the fire is issued before the alert concerning the time for replacement is issued. This reduces cases where the fire that requires emission of an alarm sound is present, but the alert concerning the time for replacement is being issued, and the resident 100 can thus not be notified of the presence of the fire. Thus, reliability relating to the alert can be improved. In particular, since the alert concerning the fire corresponds to the highest priority and is thus issued before an alert concerning any internal event is issued, setting the alert concerning the fire to the highest rank among events including the internal events improves the reliability relating to the alert concerning the fire.
  • the alert concerning the failure and the alert concerning the battery exhaustion other than the alert concerning the time for replacement are issued before the alert concerning the time for replacement.
  • the alert concerning the time for replacement of the internal events which corresponds to a relatively low emergency level is set to the lowest priority rank, thereby improving the reliability relating to the alerts concerning the other events.
  • an occurrence flag is stored. Therefore, even if a fire breaks out immediately before or during issuance of the alert concerning the presence of the internal event and interruption by an alert concerning the outbreak of the fire is allowed, the alert concerning the internal event can be resumed after the alert response to the fire ends. Alternatively, even if the internal event occurs during the issuance of the alert concerning the presence of a fire, the alert concerning the internal event is issued after the end of the alert response to the fire.
  • the control unit 10 of the basic example starts the alert response to the internal event. That is, the control unit 10 of the basic example at least once determines that internal events are present, and the control unit 10 sequentially issues alerts concerning the internal events without abandoning the alerts. However, sequentially issuing the alerts concerning the internal events is not essential even when the occurrence flags are present.
  • a control unit 10 of the present variation is configured to forego starting of an alert response to the internal event and forcibly erase an occurrence flag of the internal event even when the occurrence flag is present in a storage section 7 at the end of an alert response to a fire.
  • the outbreak of a fire may be a more severe mental load for a resident 100 than the occurrence of any internal event. For example, if after the alarm about the fire is found to be sounded by mistake and the resident 100 is relieved and stops the alarm sound, an alert concerning an internal event with a lower emergency level than the fire is sequentially issued, the resident 100 may feel discomfort or anxiety.
  • the control unit 10 makes a determination as to the internal event, for example, every one hour, the alert concerning the internal event is not issued until the next scheduled determination process.
  • the alarm 1 does not have the capability of communicating with other fire alarms.
  • the alarm 1 may also be an interconnected fire alarm with the capability of communicating with other fire alarms. In that case, the communication may be established either wirelessly or via cables, whichever is appropriate.
  • the alarm 1 of the first or second variation may have the structure shown in FIGS. 6A and 6B (according to a third variation).
  • the alarm according to this variation includes a slit 9, which is annular, recessed upward, and provided through one surface 40 (e.g., the lower surface in FIG. 6A ) of the housing 4.
  • the slit 9 is provided to extend along the circular outer periphery of the housing 4 when the housing 4 is looked up to from under the housing 4.
  • the center of the slit 9, which is annular, substantially agrees with the center of the circular outer periphery of the housing 4.
  • the slit 9 has, on its inner space (e.g., its inner bottom surface), a sound hole H1 that allows the alarm sound to come out of the housing 4 and a window hole H2 that allows the illuminating light to come out of the housing 4.
  • the first emission unit 11 (such as a loudspeaker) is housed in the housing 4 to face the sound hole H1.
  • the second emission unit 12 is housed in the housing 4 to face the window hole H2.
