Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a testing device for a residential information system that combines a fire alarm system with a two-way transmission function and an intercom system.

(Prior art) In recent years, apartment complexes and other housing complexes have been equipped with security functions to ensure safety and peace of mind such as disaster prevention and crime prevention, home information functions such as visitor notification and indoor communication, and home monitoring functions such as bath water level monitoring. The practical application of housing information systems is being pushed forward.

In such a housing information system, a housing information board is installed in each housing unit to monitor fires, theft, gas leaks, etc., as well as door intercom handsets installed outside the entrance door, collective entrance unit, and management. We have installed an intercom system that allows calls to be made between the room main unit, and in the event of an abnormal situation such as a fire or theft, an alarm will be displayed on the housing information panel and at the same time an abnormal situation will be notified in the control room. An alarm will be displayed, and the management office will be able to call the unit where the problem has occurred via intercom and make a phone call.

On the other hand, in order to transmit information in such a residential information system, the inventors of the present application have proposed a system that directly applies fire alarm equipment that performs bidirectional transmission between a repeater and a receiver. are doing.

In other words, repeaters are installed at terminals such as the doorbell handset of each dwelling unit, the collective entrance hall, and the main unit in the control room, and each repeater is connected via a transmission line to each reception installed in the control room, etc., and from the reception hall. After the call control, an abnormality detection signal such as a fire detected on the residential unit side is transmitted from the repeater of the door intercom slave unit to the receiver, which displays an alarm and further transmits it to the repeater of the main unit in the control room. The daily report is also displayed in the control room.

Furthermore, in order to automatically notify the control room in the event of an abnormality such as a fire or theft, an alarm voice synthesizer is installed on the housing information board, and when an abnormality is detected, a corresponding alarm voice message is played back and sent to the control room main unit. Automatic notifications can be made via telephone line.

According to a residential information system that uses fire alarm equipment that has such a two-way transmission function, the transmission equipment transmits fire alarm δ.
Since it is a two-equipment system, maintenance of the transmission system in the housing information system can be carried out through legally stipulated periodic maintenance points, making it possible to maintain and manage the system with high reliability.

Furthermore, when maintaining and inspecting the system, not only the transmission system of the fire alarm equipment and guns, but also the housing information board installed in each dwelling unit will be maintained and inspected. In order to be able to check maintenance points from the outside when you are not home, each doorbell has a test switch installed inside the doorbell.If the doorbell listens for the door and operates the test switch, it will simulate a fire, etc. An abnormality detection state is created, and not only an alarm is displayed on the housing information board, but also an error detection signal based on the trial theory is transmitted to the receiver and the main unit in the control room, and an alarm is displayed, indicating that the transmission system is normal. This allows you to confirm that it is working.

(Problem to be Solved by the Invention) However, in this housing information system test device that has a 52-digit test switch on the doorphone slave unit of each dwelling unit, when a test is performed on the dwelling unit side, the receiver automatically An abnormality alarm is issued to the control room, and an emergency call is placed from the housing information panel to the main unit in the control room, and an alarm voice message played by the alarm voice synthesizer is reported. Warnings will be issued more frequently. Therefore, during the test, it is expected that the person in charge of the management office will disable the alarm reception function of the receiver because alarms will be issued frequently, and in the unlikely event that a fire or other problem occurs in a residential unit other than the test. There was a problem in that even if an abnormality occurred, the control room could not receive the alarm because the alarm was reset.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned conventional problems, and when testing is conducted on the residential unit side, as a general rule, interlocking alarms to the control room side are prohibited. The purpose of the present invention is to provide a test device for a housing information system that allows an alarm to be sent to a control room only when necessary by operation on the housing unit side.

In order to achieve this objective, the present invention includes a test switch that performs a test operation of the housing information board in the door of the door intercom slave unit, and a test switch that is generated in a pseudo manner by the test operation by operating the test switch. An interlocking prohibition switch is installed to prohibit the transmission of abnormality detection signals and alarm signals to the control room, and the interlocking prohibition switch switches to the interlocking position when the door of the door intercom handset is closed (non-testing), and prevents the door from being opened. It is constructed in such a way that it switches to the interlocking prohibition position at the time of testing.

(Function) According to one configuration of the present invention, when the door of the door intercom handset is opened for testing on the residential unit side, the interlocking prohibition switch is automatically switched from the previous interlocking position to the interlocking prohibition position,
Even if a test operation is performed using the test switch, transmission of the abnormality detection signal and alarm signal simulated during the test to the control room side is prohibited, and the test operation can only be performed on the residential unit side.

Of course, if you want to interlock with the control room, you can arbitrarily interlock with the control room and check the transmission function by listening to the door and switching the interlock prohibition switch in the 1q position to the interlock position. can.

When the switch knob 86 of 0 is pressed, the switch contact of the test switch 80 is closed, and a pseudo fire detection signal is input to the repeater 21.

That is, as shown in the flowchart of FIG.
When the test switch 80 is turned on, the process proceeds to a determination block 102, where it is checked whether the interlocking prohibition switch 90 is on the site side or interlocking side.

The normal interlocking prohibition switch 90 is switched to the interlocking prohibition position when hearing -83, that is, to the field side, so the process proceeds to block 104, and the call control switch 23 inserted and connected to the call line of the door intercom Hat 208 is opened. The next block 106 prohibits the sending of transfer signals to the transmission line 60, and the process proceeds to block '108, where a test signal, that is, a pseudo A fire 1 detection signal will be output.

The alarm reception circuit 11 of the housing information panel 10a that receives the test signal through the test operation of the repeater 21 will issue a fire alarm within the residence if it is functioning normally, and will also issue a fire alarm in the doorbell slave unit (not shown). Controls the lighting of fire indicator lights. Further, the received output of the alarm receiving circuit 11 is given to the daily report Mpg synthesis circuit 15, and the corresponding alarm voice message signal is outputted from the alarm voice synthesis circuit 15 to the telephone line 70 via the telephone call switching circuit 18. Since the telephone call control switch 23 is opened by the operation of the repeater 21 based on the (2) motion prohibition output of the interlocking prohibition switch 90, the alarm voice message signal is not sent to the telephone line 70.

By prohibiting the transmission of transfer signals from the repeater 21 and cutting off the communication line based on this interlocking prohibition switch 90, the test switch 8
Even if a pseudo-alarm reception operation is performed on the dwelling unit side by operating 0, the alarm will not be displayed on the fire receiver set up in the control room 30, and the alarm voice message will not be reported by emergency call to the main hall 40 of the control room. Test operations can only be performed on the residential unit side.

On the other hand, if it is desired to interlock the control room side with the test operation, the interlock prohibition switch 90 is turned on to bring the door 83 into the same state as closed, and the test switch 80 is operated in this state.

The test operation performed by operating the test switch 80 in a state where the commuting prohibition of the interlocking prohibition switch 90 is canceled is the same as that during normal abnormality detection, and the transmission 1 control unit 32 of the receiver 30
A pseudo abnormality detection signal from the test is given to the receiver 30 from the medium-sized device 21 via the transmission line 60 under the control of the alarm display unit 34 and the alarm display unit 44 of the control room main hall 40. At the same time, housing information board 10a and management complete explanation)

0 through the telephone line 70. Note that this embodiment outputs sound as an alarm device, but a bell,
An alarm sound such as a buzzer may also be used.

(Effects of the Invention) As described above, according to the present invention, there is a test switch that performs a test operation of the housing information board in the door of the door intercom slave unit of each dwelling unit, and a test operation is simulated by operating the test switch. An interlocking prohibition switch is installed to prohibit the transmission of abnormality detection signals and alarm signals generated during operation to the control room side, and the interlocking prohibition switch switches to the interlocking position when the door of the door intercom handset is closed, and interlocks when the door is opened. Since it is configured to switch to the prohibited position, when the door of the door intercom handset is opened when performing an operation test on the residential unit side, the interlocking prohibition switch will automatically switch to the interlocking prohibited position, and the control room side will be prevented from operating during the test operation. The display of alarms and the output of alarm voice messages to the control room are prohibited, and test operations can only be performed at the site.

In addition, if the interlocking prohibition position is returned to the interlocking position with the door open, the doorbell will display an alarm and send a non-hV alarm voice message to the control room in conjunction with the test operation, and the fire alarm system will It is also possible to recognize the transmission sensitivity of a bidirectional transmission line as 6 (i).
