Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security monitoring call system installed in an apartment house or a building. 2. Description of the Related Art A security monitoring communication system of this type generally includes a security sensor, a house information panel, and an alarm monitoring panel. The security sensor is installed in each house and transmits an abnormality detection signal by detecting an abnormality such as a fire or a gas leak. The house information panel is installed in each house like the security sensor, and issues an alarm by receiving an abnormality detection signal of the security sensor. The alarm monitoring panel is installed in a manager's office or the like, centrally monitors alarms on the house information panel, and includes an alarm stop switch. Further, the alarm monitor panel has a communication line between the alarm information panel and the house information panel, and can communicate with each house. [0003] In the above-mentioned security surveillance communication system, when a house information panel issues an alarm, an alarm stop switch is operated on the alarm monitoring panel to provide an alarm. Can be stopped. However, the warning can be stopped without judgment without checking the actual situation of the house,
For example, there is a problem that it is determined that the report is a false report even though the report is not a false report, and that the response to the occurrence of the abnormality is delayed. The present invention has been made in view of the above circumstances, and has as its object to provide a security surveillance call system with improved reliability by issuing an alarm until the actual situation of a house is confirmed. To be. [0005] In order to solve the above-mentioned problems, a security monitoring and communication system according to the present invention is provided in each dwelling, and detects a fault and transmits a fault detection signal by detecting a fault. Between the housing information panel installed in each dwelling and issuing a warning by receiving the abnormality detection signal of the security sensor, and the housing information panel installed in the manager's room etc. to centrally monitor the warning of the housing information panel and between the housing information panel An alarm monitoring panel having a communication line, wherein the housing information panel is alarmed by receiving a call signal of the alarm monitoring panel through the communication line while receiving an abnormality detection signal of the security sensor. was stopped and, Ri name and configured to re-generate an alarm does not hold the call until completion of reception call signals, passing
When talking, the alarm stops even after the call ends
When a call is not made, the call signal is sent.
The feature is that the alarm is issued again after the end
It shall be the. According to this configuration, at the time of an abnormal alarm, a call between the alarm monitoring panel and the house information panel is established, or the user goes to the alarm source and directly operates the house information panel. , An alarm will be issued until the actual condition of the residence is confirmed. An embodiment of the present invention will be described below with reference to FIGS. This security monitoring call system comprises a security sensor 1, a housing information panel 2, an alarm monitoring panel 10
And The security sensor 1 is installed in each dwelling and transmits an abnormality detection signal by detecting an abnormality such as a fire or gas leak. The home information panel 2 is installed in each dwelling similarly to the security sensor 1. The home information panel 2 generates an alarm by receiving an abnormality detection signal of the security sensor 1, and outputs an alarm to an alarm monitoring panel 10 described later. Report contents and house number. The housing information panel 2 stops the alarm by receiving the call signal of the alarm monitor panel 10 through the communication line while receiving the abnormality detection signal of the security sensor 1, and stops the call until the reception of the call signal. If is not established, an alarm is issued again. Specifically, the sensor receiving circuit 3, the CPU 4, the call control circuit 5
, NOT circuit 6, AND circuit 7, alarm sound output circuit 8, etc. The sensor receiving circuit 3 is a security sensor
1 is to receive the abnormality detection signal. CPU4
The sensor receiving circuit 3 performs a predetermined process by receiving the abnormality detection signal. The output of the CPU 4 becomes HIGH when the sensor receiving circuit 3 receives the abnormality detection signal, and becomes LOW when the sensor receiving circuit 3 does not receive the abnormality detection signal. The call control circuit 5 receives a call signal from the alarm monitoring panel 10 and performs predetermined control. The output of the call control circuit 5 is HIGH when a call signal is received, and LOW when a call signal is not received.
It becomes. In addition, when the call state is entered while the call signal is being received, the call control circuit 5 sets the output to LOW after the reception of the call signal is completed and the security sensor 1 recovers to a state where no abnormality is detected. . The NOT circuit 6 inverts the output of the call control circuit 5. That is, the call control circuit
When the output of 5 is HIGH, its own output is set to LOW, and when the output of the call control circuit 5 is LOW, its output is set to HIGH. The AND circuit 7 is connected to the CPU 4
And the output of NOT circuit 6 as inputs,
A predetermined output is performed. That is, only when both the output of the CPU 4 and the output of the NOT circuit 6 are HIGH, its own output is set to HIGH, and in other cases, the output is set to LO.
W. The alarm sound output circuit 8 outputs an alarm sound via the speaker 9 only when the output of the AND circuit 7 is HIGH. The alarm monitoring panel 10 is installed in a management room or the like,
It is for centrally monitoring the alarm on the housing information panel 2. The alarm monitoring panel 10 has a communication line with the house information panel 2, and can communicate with each house. This security monitoring call system operates as follows. First, when the security sensor 1 detects an abnormality, the house information panel 2 issues an alarm and notifies the alarm monitoring panel 10. Next, the alarm monitoring panel 10
Sends a call signal to the housing information panel 2 via the telephone line, and the housing information panel 2 temporarily stops the alarm.
Then, when the alarm monitoring panel 10 and the house information panel 2 are in a call state, the stop of the alarm is continued even after the call ends. Here, when the alarm monitoring panel 10 and the housing information panel 2 do not enter the talking state, after the transmission of the calling signal by the alarm monitoring panel 10 is completed, an alarm is again issued on the housing information panel 2 , and the manager, etc. Visits the scene and stops the alarm. [0016] Such a security surveillance call system includes:
At the time of an abnormal alarm, a call between the alarm monitoring panel 10 and the house information panel 2 is established, or
Directly, or issue an alarm until the actual condition of the house is confirmed.Therefore, there is no problem such as stopping the alarm with arbitrary judgment and delaying the response to the occurrence of abnormality, and reliability is improved. improves. According to the security surveillance call system of the present invention, when an alarm is issued, a call between the alarm monitor and the house information panel is established, or the user goes to the alarm source to directly access the house information panel. An alarm is issued until the actual situation of the dwelling is confirmed by operation or operation, so reliability is improved.
