DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention switches a monitored area, for example, a store, an office, a house, or the like, to a security mode according to a preset schedule, and detects a fire or an intrusion in the security area in the security mode. The present invention relates to a security system for monitoring the occurrence of an abnormality at a remote monitoring center.

[0002]

2. Description of the Related Art Conventionally, occurrence of an abnormality such as a fire or intrusion in a monitored area is detected by a sensor installed in a monitored area such as a store, an office or a house. As a security system that sends an alarm to a remote monitoring center via a communication line such as a telephone line and monitors the occurrence of abnormalities in the monitoring area at the monitoring center, if there are people inside the building during the daytime etc. Set the monitoring area to the release mode, and when the inside of the building becomes unmanned at night or on holidays, set the monitoring area to the security mode, and switch between the security mode and the release mode by operating the numeric keypad, card reader, etc. (A first security system), or a security system that automatically switches a monitoring area to a security mode at a preset security start time. (2) Security system, such as a CD / ATM corner of a financial institution, when a predetermined closing time is reached, the presence or absence of a resident is checked, the entrance is closed, and the inside of the corner is switched to security mode. (Third security system) or a security system that sends an alarm to the monitoring center if the store closing operation is not completed and the monitored area cannot be switched to the security mode by a preset security start time. When the security start time is changed by a (fourth security system) or a survivor or a guard at the monitoring center and a new security start time is set, this time is stored as a new security start time, Thereafter, a security system (fifth security system) that switches the monitoring area to the security mode when the security start time comes has been proposed. I have.

[0003]

However, in the first security system among the conventional security systems, if the last leaver forgets to start the security operation to switch the monitoring area to the security mode, the security area will be lost. However, in the second security system, the problem of the first security system is solved, but the security start time is not solved. The problem is that the surveillance area is automatically switched to the security mode regardless of the presence or absence of the remnant in the surveillance area. Therefore, an unnecessary alarm is transmitted to a remote monitoring center as the intruder. However, in the third security system, the equipment (CD machine, ATM machine, automatic contract machine, etc.) installed at the CD / ATM corner depends on the selected menu (work contents). If you select a menu that takes a long time to work just before the closing time, the closing time will be too long, and the customer will be detected as a residual person during this work. Therefore, there is a problem that the monitoring area cannot be switched to the security mode until the work is completed. In the fourth security system, if a menu requiring a long work time is selected, the work is completed. The security start time arrives before sending, and unnecessary alarms are sent to the monitoring center. In the fifth security system, the problem of the fourth security system is prevented to some extent. Although it is possible, once the security start time is changed, after that, the security start time is changed and the original security start time is changed after the security start time is changed It was pointed out that there was a problem that it had to be corrected every moment and was troublesome.

Accordingly, the present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a security system in which a monitoring area is switched to a security mode at a preset security start time. If a survivor in the monitoring area or a supervisor at the monitoring center inputs the extension time, the monitoring area is switched to the security mode when the extension time is reached, and an unnecessary alarm is not transmitted to the remote monitoring center. The purpose of the present invention is to provide a security system that takes into consideration such measures.

[0005] Another object of the present invention is to automatically set a security start time or an extension time at a preset security start time even if the last leaver forgets to perform a security start operation for switching the monitored area to the security mode. An object of the present invention is to provide a security system that is superior in security because the monitored area is switched to the security mode and the monitored area is reliably switched to the security mode.

[0006] Another object of the present invention is to provide a method for starting security on a preset basis after an extension time is input even if a survivor in a monitoring area or a supervisor at a monitoring center inputs an extension time. An object of the present invention is to provide a security system that does not need to change a preset security start time and does not need to correct the security start time by switching the monitoring area to the security mode at the time, thereby reducing the trouble.
