[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a security system for monitoring a monitored property such as a building, and also relates to a monitoring device used for the security system.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a security system in which a controller (monitoring device) and a speaker (sound output device) are arranged in a monitored property and connected to a security center at a remote location via a communication line. In this security system, when an abnormality is detected in the monitored property, a notification is sent from the controller to the security center via the communication line. In the security center, if the controller determines that an abnormality has occurred in the monitored property, it takes necessary measures such as dispatching a countermeasure to the monitored property.
[0003]
At the same time, if the abnormality is an intrusion abnormality or the like, a threatening voice for instructing the intruder to leave is issued through a speaker arranged in the monitored property. In addition, if the abnormality is a fire, etc., a fire notice and prompt evacuation request will be made to the people in the monitored property through a speaker.
In such a monitoring system, tests such as confirmation of sensor operation and confirmation of a connection state with a security center are performed when a controller is first installed in a monitored property and when maintenance and inspection of the controller are performed. At the same time, the test is also performed on the output of voice sent from the security center and the voice input of the microphone in the monitored property.
[0004]
In the conventional voice test, an installation contractor or maintenance staff (hereinafter referred to as “installation contractor”) in the monitored property communicates with the security center controller, and the test voice sent from the security center is received. The installer confirmed the output from the speakers in the monitored property.
[0005]
[Problems to be solved by the invention]
In the above-mentioned conventional voice test, it is indispensable to participate in the control center of the security center. Therefore, as the number of monitored properties increases, the frequency of the voice test increases and the burden on the controller increases.
For this reason, there was a problem in monitoring the abnormality of the monitored property, which is the original operation of the controller.
[0006]
In addition, when an abnormality occurs in the monitored property, the controller is given priority over monitoring the monitored property abnormality and giving instructions to the counselor over the audio test, so the audio test was temporarily suspended. During this time, the installer had to wait for the controller's abnormality handling process to end and the voice test to resume.
It is an object of the present invention to enable a voice test only by an operation on the monitoring device side in a monitoring property in a security system that outputs the voice sent from the security center from the sound output device in the monitoring property. It is.
[0007]
Moreover, this invention aims at providing the monitoring apparatus used for the said security system.
[0008]

Furthermore, it is possible to simultaneously confirm the sound input of the microphone installed in the monitored property and the sound output of the speaker.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows the configuration of a security system.
A controller (monitoring device) 12 is installed in a monitored property 11 such as a building. The controller 12 includes an image sensor 13, a speaker (audio output device) 14, an emergency button 15, an intrusion sensor 16, and a fire arranged in the monitored property. A sensor 17 and a mode setting unit 18 are connected. The controller 12 is connected to a security center device 22 installed in a remote security center 21 via a telephone line (communication line) 19. Although only one controller 12 is shown in the figure, there are usually a plurality of monitored properties, and the controllers 12 of the monitored properties are connected to the security center device 22.
[0014]
A plurality of image sensors 13 are installed in the monitoring object 11 and have a function of determining whether there is an abnormality such as an intrusion from an image obtained by photographing a monitoring area including a monitoring target such as a window or a door. Also, necessary images are output to the outside. Furthermore, it has a built-in microphone that collects ambient sounds. The microphone is also used for an audio test described later.
When the image sensor 13 and the intrusion sensor 16 detect an intruder, the speaker 14 is disposed at a place where a threatening voice can be output to the intruder. Further, when the fire sensor 17 detects a fire, the fire sensor 17 is arranged in a place where a fire occurrence notification and an evacuation request can be made to the personnel in the monitored property 11.
[0015]
The mode setting unit 18 sets the security mode of the monitored property 11 by an operation of a user or the like. The user who finally comes out from the monitored article 11 at night operates the mode setting unit 18 to set the alert set mode. As a result, when an intrusion abnormality or the like occurs in the monitored property 11, an abnormality notification is sent to the security center device 22. A user who first enters the monitored property 11 in the morning sets the alert release mode. Thereby, even if there is a person in the monitored property 11, the intrusion abnormality is not reported to the security center device 22.
[0016]
In addition, when a counselor or maintenance person who is qualified to operate the mode setting device 18 is dispatched to the monitored article 11, the patrol mode and the maintenance mode are set by the operation of the counselor or the like. During these handling modes, the alert set mode is canceled and the handling staff can perform necessary work.
If an intrusion abnormality is detected by the image sensor 13 or the intrusion sensor 16 or a fire abnormality is detected by the fire sensor 17 during the warning set mode, the controller 12 sends a warning to the security center device 22 via the telephone line 19. Anomaly notifications are sent to them. Further, when the emergency button 15 is operated during the alert release mode or a fire abnormality is detected by the fire sensor 17, the controller 12 notifies the security center device 22 of an abnormality.
[0017]
On the display of the security center device 22, the type of abnormality that has been sent, an image, and the like are displayed. After the controller determines the state of the monitored property, it takes necessary measures such as dispatching a coping person.
At the same time, when confirming an intrusion abnormality, the controller makes an intimidating announcement through the speaker 14 arranged in the monitored property in order to move the intruder away from the monitored property. In addition, when a fire breaks out, a fire notice and evacuation guidance are announced to the people in the monitored property. The voice of the announcement is emitted from the speaker 14 via the telephone line 19 and the controller 12.
[0018]
A test for sound output by the speaker 14 is performed at the time of initial setting of the controller 12 or at the time of maintenance and inspection. The operation during this audio output test will be described later.

[0020]
The display unit 37 displays the monitoring state of the monitoring area on the screen. When an abnormality is detected, the display unit 37 sounds a buzzer and displays the type of abnormality and the location where the abnormality has occurred on the screen. The display unit 37 is also used during initial setting work of the image sensor 13. The operation means 38 is used when the image sensor 13 is initially set or changed.
FIG. 3 is a diagram illustrating the configuration of the storage area of the control unit 31 of the controller 12.
[0021]
In the mode storage area 41, the security mode set by the mode setting unit 18 is stored. The device address management area 42 stores each sensor and its address. The image sensor-speaker correlation management area 43 stores the correspondence between each speaker 14 and the image sensor 13. In the sound data recording area 44, sound for sound test sent from the image sensor 13 and sent to the security center device 22 is temporarily stored.
[0022]
The voice request signal storage area 45 stores a voice request signal sent to the security center device 22 during a voice test. The voice signal reception management area 46 temporarily stores the voice sent from the security center device 22 during the voice test.
FIG. 4 shows the configuration of the image sensor 13.
The image sensor 13 is provided with a control unit 51 and a power source 52 configured by a CPU or the like. Each part in the sensor is controlled by the control means 51 and is supplied with power from the power source 52. The power source 52 may be a battery, a combination of an external AC power source and a battery, or a power supply from the controller 12.
[0023]
A storage unit 53 is connected to the control unit 51. In the storage unit 53, in addition to a program for operating the image sensor 13, an image taken by the imaging unit 54, a security mode such as a warning set mode or a warning release mode, and a monitoring state indicating normality or abnormality of the monitored property Remembered.
The imaging means 54 for photographing the monitoring area is constituted by a CCD camera. Infrared light projecting means 55 is provided, and infrared light is projected onto the monitoring area.
[0024]
The image processing unit 56 determines whether or not an abnormality has occurred based on the image stored in the storage unit 53. Note that the method for determining whether or not an abnormality has occurred is not directly related to the gist of the present invention and will not be described here, but any method can be adopted.
The display means 57 is constituted by an LED and is used for a voice test described later.
[0025]

The microphone 62 is provided to collect sound in the monitoring area when an abnormality occurs and to perform a sound test.
FIG. 5 shows a configuration of the security center device 22.
[0027]
The security center device 22 includes a control unit 71 configured by an MPU, a power supply circuit 72, a communication interface 73, a communication management unit 74, an operation unit 75, and a display unit 76, as in the conventional device. Further, in the present embodiment, an audio data storage unit 77 and an audio input / output control unit 78 are provided to perform an audio test.
The voice data storage unit 77 stores standard voice data created in advance and voice data sent from the controller 12.
[0028]
As an example of standard audio data,
Intimidation Voice: “This building is in security. I've reported to the security company.” “I took a picture of you and reported it to the police.” “The police are coming soon.”
Emergency voice: “I reported to the security company. A security guard will arrive soon.”
Equipment voice: “We have reported to the equipment company. We are confirming it now.”
Voice for fire: “Do not panic. A fire has occurred. Please evacuate from the emergency exit.”
Test audio: “Now audio test in progress”.
[0029]
The voice input / output control unit 78 performs control to select necessary voice from the standard voice data based on the voice request signal sent from the controller 12 and send it to the controller 12. Alternatively, the audio data sent from the controller 12 is stored in the audio data storage unit 77 and further returned to the controller 12. The microphone 79 is used when the controller performs intimidation, guidance, or the like to a person who is in the monitored property 11.
[0030]
Next, the operation at the time of the voice test in the monitoring system described above will be described.
The voice test is performed by an installer when the monitoring system is installed in the monitored property 11. At the time of performing the voice test, various setting data are already registered in the controller 12, and the security center 21 recognizes that the controller 12 is temporarily operating. In the security center 21, each test is finished and all functions are confirmed, and then the operation is performed. The voice test is also performed by maintenance personnel during maintenance inspection.
[0031]
As the voice test, there is a “standard voice test” in which standard voice data is recorded in the security center device 22 in advance, and this is called from the controller 12 and output from the speaker 14. In addition, the test voice is collected from the microphone 62 installed in the security area, the test voice is sent from the controller 12 to the security center 22, the reply is sent from the security center 22 to the controller, and is outputted from the speaker 14. There are two types.
[0032]
(Example 1)
The general operation of the standard voice test will be described with reference to the timing chart of FIG.
First, the telephone line 19 is connected between the controller 12 and the security center device 22. When the line connection is completed, a voice request signal is issued from the controller 12. On the other hand, after a response signal is transmitted from the security center device 22, an audio signal based on the audio request signal is transmitted. The controller 12 reproduces and outputs sound from the speaker 14. The audio signal sent from the security center device 22 is not limited to one time but may be sent a plurality of times.
[0033]
When the voice output test is completed, the controller 12 transmits an end signal and opens the telephone line. When the security center device 22 receives the end signal, it opens the telephone line 19.
According to the fixed voice test, it is not necessary for the controller to participate in the test at the security center 21, and the voice test can be performed only on the controller 12 side. Moreover, even if the number of controllers 12 increases, the burden on the controller of the security center 21 does not increase. Further, tests of the speaker 14 and the telephone line 19 can be performed simultaneously.
[0034]
Detailed operations in the controller 12 and the security center device 22 will be described below.
FIG. 7 and FIG. 8 are operational flows of the standard voice test of the controller.
To start the voice test, the installer operates the mode setting unit 18 to set the security mode to the maintenance mode. Then, the selection screen 0 (not shown) is displayed on the display unit 37 of the controller 12. Since various tests are displayed on the selection screen, the following fixed voice test is started by selecting the fixed voice test.
[0035]
In step S11, a selection screen 1 (not shown) on which a list of speakers to be tested is displayed is displayed. In step S12, the installer selects the speaker 14 to be tested for audio output. The speaker 14 can be freely selected from one selection to all selections. When the speaker 14 is selected, “typical voice test in progress” is displayed on the display unit 37.
[0036]
In step S13, the telephone line 19 is connected. The time required for this line connection is about 60 seconds for a public line and about 5 seconds for ISDN. If the line connection is not possible, an error message “line connection NG” is displayed on the display unit 37 in step S14. When this display appears on the display unit 37, the installer performs the necessary recovery process (recovery process 1), and returns to step S11 if the recovery is performed.
[0037]
When the line connection is completed in step S13, a selection screen 3 (not shown) for selecting the audio signal type is displayed in step S15, and an LED (not shown) indicating the line connection is lit. As the audio signal type, the above-described threatening voice, emergency voice, equipment voice, and fire voice are displayed. In step S16, one audio signal is selected. In the following description, it is assumed that the threatening sound is selected.
[0038]
The controller 12 sends a threatening voice request signal to the security center device 22 and starts a timer T0 for managing reception of response signals. The timer T0 times out in 1 minute (step S17). Then, it waits to receive a response signal from the security center apparatus 22 (step S18). If a response signal is received before the timer T0 times out in step S19, the process proceeds to step S23. If the time expires before receiving the response signal, the process proceeds to step S20.
[0039]
In step S20, since no response signal was received within the time, an error message “response signal NG” is displayed on the display unit 37, the timer T0 is reset in step S21, and the telephone line 19 is connected in step S22. Open. When this display appears on the display unit 37, the installer can grasp that there is an abnormality in the connection between the security center device 22 and the telephone line 19, and performs necessary recovery processing (recovery processing 2), and then goes to step S11. Return.
[0040]
If a response signal is received before the timer T0 expires, a timer TA for audio signal reception management is started in step S23. The timer TA expires in 1 minute. Also, the timer T0 is reset. Then, it waits to receive an audio | voice signal from the security center apparatus 22 (step S24). If an audio signal is received before the timer TA expires in step S25, the process proceeds to step S29. If the time expires before receiving the audio signal, the process proceeds to step S26.
[0041]
In step S26, since no voice signal was received within the time, an error message “voice signal NG” is displayed on the display unit 37, the timer TA is reset in step S27, and the telephone line 19 is connected in step S28. Open. When this display appears on the display unit 37, the installer performs the necessary recovery process (recovery process 3), and returns to step S11 after the recovery.
[0042]
If an audio signal is received before the timer TA expires, an audio output process is performed in step S29. The audio output process in step S29 will be described below.
When the audio signal is received, the timer TB is started with reference to the image sensor-speaker correlation management area 43 (see FIG. 3). The set value of the timer TB is set to the time necessary for the installer who has been operating with the controller 12 to move to the corresponding image sensor 13. The set value of the timer TB may be a constant value or a variable value.
[0043]
When the installer moves to the corresponding image sensor 13, the timer TB expires, and the controller 12 switches and connects to the selected speaker 14, and outputs threatening sound from the speaker 14. Thereafter, the timer TB is reset and the process proceeds to step S30.
In step S30, an end signal is sent to the security center device 22. In step S31, the telephone line 19 is opened, and the process returns to step S11. Thereafter, another type of voice is tested, or the termination is selected on the selection screen 1 and the routine voice test is terminated.
[0044]
A routine voice test operation in the security center device 22 will be described with reference to FIG.
The security center device 22 receives the voice request signal from the controller 12 and executes voice test processing (step S51). When the voice request signal is received, the voice input / output control unit 78 returns a response signal to the controller 12 (step S52). In step S53, the received voice request signal information is automatically recorded in the communication management unit 74 and managed as history information.
[0045]
In step S54, a threatening voice, which is a requested voice in the voice request signal, is selected from the voice signal storage section 77 from the voice storage section 77, and the voice signal is set in the transmission buffer of the communication interface 73. In step S55, the controller 12 Send to. In step S56, information such as the returned voice signal and the address of the security target of the transmission destination is automatically recorded in the communication management unit 74, managed as history information, and the process ends.
[0046]
As described above, in the routine voice test of the first embodiment, the voice request signal is sent from the controller 12 to the security center apparatus 22, and the security center apparatus 22 automatically returns a corresponding routine voice. The controller 12 can output the received standard voice from the speaker 14 installed in the monitored property.
Therefore, even if the number of controllers 12 connected to the security center device 22 via the telephone line 19 is increased, it is not necessary for the controller to check the display every time the test is performed, and the burden on the controller can be reduced.
[0047]
In particular, when another monitored property becomes abnormal during the audio test as described above, according to the first embodiment, the controller does not need to interrupt the audio test in order to take measures against the abnormality. At this time, on the monitored property side during the voice test, the fixed voice is automatically returned from the security center device 22 by the operation of the controller 12, so that the installer can perform the test without being interrupted. It becomes.
[0048]
Conventionally, the voice of the controller inputted by voice from the microphone 79 at the security center 21 is transmitted to the controller 12 via the telephone line 19, and this voice is reproduced from the speaker 14. In contrast to this, in the first embodiment, the standard voice is stored in the security center device 22 in advance, and the controller 12 that receives this voice signal reproduces the voice from the speaker 14, so the voice test is performed with clear voice. It can be carried out.
[0049]
In the first embodiment described above, the voice test, which is the original purpose, is performed, and simultaneously with the restoration processes 1 to 3, other tests of the monitoring system can be performed simultaneously to narrow down the contents of the failure.
The restoration process 1 in step S14 is a case where the telephone line 19 cannot be connected. The reason is that the telephone line 19 is not connected or the destination telephone number is incorrect. The processing method includes confirmation of line connection and confirmation of a telephone number.
[0050]
The restoration process 2 in steps S20 to S22 is a case where the telephone line 19 is connected but the ACK signal from the security center 21 is not returned. As the reason, there is a communication failure of the controller 12, a down on the security center 21 side or a communication busy. As the processing method, there is an inspection of the controller or a retest after a certain time.
[0051]
The recovery process 3 in steps S26 to S28 is a case where no audio signal is returned. Reasons include a mismatch in the contents registered in the controller 12, a communication failure of the controller 12, a device abnormality, a failure on the security center 21 side, and the like. As the processing method, there are confirmation of registration contents of the controller 12, device replacement, and the like.
[0052]
(Example 2)
With reference to the timing chart of FIG. 10, an outline of the operation when the audio loopback test is performed will be described. The installer operates the controller 12 and starts an audio loopback test.
When a telephone line is connected between the controller 12 and the security center device 22, a start request signal is sent from the controller 12. In response to this, a response signal is sent from the security center device 22.
[0053]
The controller 12 starts counting the timer with the reception of the response signal as the start time (t = 0). At the same time, the controller 12 sends a sound collection request signal to the image sensor 13 to be tested.
In the image sensor 13, the microphone 62 is turned on. When the installer makes a sound to the microphone 62, the sound is transmitted to the controller 12 and is recorded for 5 seconds in the controller 12. When the voice data recorded by the controller 12 is transmitted to the security center device 22, the security center device 22 returns the voice data to the controller 12. 5 seconds after t = 0, the controller 12 sends a sound collection stop signal to the image sensor 13 and then outputs the sound returned from the security center device 22 from the speaker 14 corresponding to the image sensor 13. . The speaker output time is 7 seconds including communication processing.
[0054]
Thereafter, these processes are repeated, and when the timer counts up (5 minutes), an end signal is sent to the security center device 22.
Detailed operations in the controller 12, the image sensor 13, and the security center device 22 will be described below.
11 to 13 are operation flows of the controller.
[0055]
Until the maintenance mode is set and the selection screen 0 is displayed, the routine is the same as the routine audio output test of the first embodiment. By selecting the audio loopback test on the screen 0, the following audio loopback is performed. The test starts.
In step S61, the selection screen 2 (not shown) on which a list of speakers to be tested is displayed is displayed on the display unit 37 of the controller 12. When the image sensor 13 to be tested is selected in step S 62, “During Audio Loopback Test” is displayed on the display unit 37. (Step S62)
In step S63, the telephone line 19 is connected. Here, the process from step S64 to the error display and the return to step S61 when the line connection cannot be made is the same as step S14 in the first embodiment. In addition, here, the restoration process 1 is performed, and this restoration process 1 is the same as step S14.
[0056]
When the line connection is completed in step S63, in step S65, the controller 12 sends a start request signal to the security center device 22, activates a timer T0 for reception management of response signals, and displays an LED ( Lights up (not shown). Timer T0 times out in one minute. Then, it waits for a response signal to be received from the security center device 22 (step S66). If a response signal is received before the timer T0 times out in step S67, the process proceeds to step S71. If the time is up before receiving the response signal, the process proceeds to step S68.
[0057]
Steps S68 to S70 when the response signal is not received are the same as steps S19 to S22 of the first embodiment, and the recovery process 2 performed here is the same as that of the first embodiment. .
If a response signal is received before the timer T0 expires, the timer T1 for time management of the voice loopback test is started in step S71. In order to prevent exclusive use of one of the lines of the security center device 22 for a time longer than necessary for the test, the timer T1 times out in 5 minutes. Also, the timer T0 is reset. Thereafter, a sound collection request signal is sent to the image sensor 13 selected in step S65 (step S72), and a timer T2 for managing the sound collection time is started. Timer T2 times out in 5 seconds.
[0058]
In step S 73, the audio data sent from the image sensor 13 is recorded in the audio data recording area 44 of the control unit 31. When the audio data is compressed and recorded for 5 seconds until the timer T2 expires, the process proceeds from step S74 to step S75, a sound collection stop signal is sent to the image sensor 13, and the timer T2 is reset.
When the timer T3 for managing the voice output time including the time lag in the communication process is started in step S76, the timer T3 compressed in step S73 is sent to the security center 21 (step S77). The timer T3 times out in 7 seconds. In this embodiment, the voice is stored for 5 seconds and then sent to the security center device 22 in a collective manner. However, the present invention is not limited to this, and the collected voice is sent to the security center device 22 as needed. You may make it send out.
[0059]
In step S78, it waits to receive a voice response signal from the security center device 22. When the voice response signal is received, the voice output process of step S79 is performed.
When the voice response signal is received, the image sensor-speaker correlation management area 43 (see FIG. 3) is referred to, the speaker 14 corresponding to the image sensor 13 selected in step S62 is selected, and the switching connection to the speaker 14 is made. And output audio. The audio output process is terminated and the process proceeds to step S79. Regardless of the presence or absence of the audio output process (step S79), when the timer T3 times out (Y in steps S80 and 81), the timer T3 is reset in step S82, and the process proceeds to step S83. In step S83, it is determined whether or not the timer T1 has expired. If 5 minutes, which is the time of the audio loopback test, has not elapsed, the process returns to step S71, and the sound collection for 5 seconds and the sound output for 7 seconds are repeated. In this way, in the audio loopback test, the test is continued for one image sensor 13 for 5 minutes, so the time until moving to the image sensor 13 is set as in the routine audio test of the first embodiment. No delay timer TB is provided.
[0060]
When 5 minutes have elapsed, an end signal is sent to the security center apparatus 22 in step S84, the timer T1 is reset, the telephone line is released, and the process returns to step S61. Thereafter, the same test is performed for the other image sensors 13 or the end is selected on the selection screen 2 to end the audio loopback test.
Here, the controller 12 manages the test time by the timer T1 so that one of the lines of the security center device 22 is not occupied, and the line is released when a predetermined time (5 minutes) is reached. For this reason, no extra burden is placed on the security center device 22.
[0061]
Moreover, the speaker 14 corresponding to the microphone 62 (image sensor 13) is managed. In the sound loopback test, when the microphone 62 is selected, the collected sound can be output from the corresponding speaker 14 via the security center device 22.
The operation of the audio loopback test in the image sensor 13 will be described with reference to FIG.
[0062]
When the image sensor 13 receives a sound collection request signal from the controller 12 through the communication means 58 (step S101), the display means 57 is turned on to inform the installer of the sound collection time (step S102), and the microphone 62 is turned on (step S103). Then, the sound collected by the microphone 62 is sent to the controller 12 (step S104). The sound transmission is continued for 5 seconds until the sound collection stop request signal is received from the controller 12 (step S105). When the sound collection stop request signal is received, the display means 57 is turned off in step S106, and the sound collection is finished. (Step S107). When the image sensor 13 receives the sound collection request signal again after 7 seconds, the image sensor 13 resumes the above operation. In this embodiment, the sound collection time (5 seconds) is managed by the controller 12, but the image sensor 13 may perform the same time management.
[0063]
Therefore, when the sound collection request signal is received from the controller 12, the display means 57 is turned on and the sound collection is continued for 5 seconds. When the sound collection stop signal is received, the display means 57 is turned off and the sound collection is stopped for 7 seconds. . Further, when a sound collection request signal is received from the controller 12, the same operation is repeated. Since the sound collection request signal and the sound collection stop signal are sent from the controller 12 for 5 minutes (timer T1), the operation of FIG. 14 is continued for 5 minutes.
[0064]
The operation of the voice loopback test in the security center device 22 will be briefly described.
In the security center device 22, when an audio signal is received from the controller 12, the audio input / output control unit 78 stores the audio signal in the audio data storage unit 77. When recognizing that it is an audio signal, information such as an address to be guarded and a signal name is automatically recorded in the communication management unit 74 for the received audio signal. Then, the voice data portion is returned as it is to the transmission source controller 12 as a voice response signal. At this time, the fact that the audio signal has been returned is automatically recorded in the communication management unit 74.
[0065]
As described above, in the voice loopback test of the second embodiment, the voice input from the microphone 62 installed in the monitored property is sent to the security center device 22 via the controller 12, and the security center device 22 automatically The controller 12 can output the received voice from the corresponding speaker 14 installed in the monitored property.
[0066]
Therefore, the test of the microphone 62 installed in the monitored property can be performed simultaneously with the voice test. In particular, since the installer can directly confirm the voice he / she uttered, the microphone 62 and the speaker 14 can be adjusted as necessary.
Further, since the timing of the sound collection time of the microphone 62 and the output time of the speaker 14 are shifted, howling does not occur even if the microphone 62 and the speaker 14 are close to each other.
