Abstract

PROBLEM TO BE SOLVED: To provide burglar prevention by expanding a range in which an alarm generation is possible. SOLUTION: By pushing a warning button 3 when warning mode is set, and when electric lock operation buttons 10a, 10b and 10c are not pressed, an electric lock 2 is not inputted to a code number input device 12 and, when it is unlocked or a door or the like in which the electric lock is provided is opened, an alarm device contact point circuit 5 is turned on by a CPU11 of an electronic lock controller 1 and an alarm is generated from an alarm device 6. Thereafter, when the warming button 3 is pressed, the alarm device contact point circuit 5 is turned off, and the alarm generation by the alarm device 6 is stopped. By providing the alarm device 6 in each place, a range in which the alarm is not informed is deleted and it is possible to deal with burglar prevention at any place.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock control device, and more particularly to an electric lock control device capable of widening an audible range of a buzzer sound.

[0002]

2. Description of the Related Art Conventionally, by inputting a password or pressing an electric lock driving button, a door or the like provided with an electric lock to be unlocked upon input of an electric lock driving signal is opened. In such a case, there has been an electric lock control device for the purpose of crime prevention by blinking a warning indicator light or the like and sounding a buzzer. As shown in FIG. 3, this type of electric lock control device includes an electric lock 20 installed at an entrance door or the like, and an electric lock controller 21 for inputting a signal from the electric lock 20. The electric lock controller 21 has an alarm button 22 for setting the alarm mode, an alarm indicator 23 for displaying the alarm mode setting, and a sound when the electric lock 20 is opened when the alarm mode is set. A buzzer 24 is provided.

In such an electric lock control device, when the alarm button 22 is pressed to set the alarm mode, the alarm indicator light 23 is turned on, and whether the lock is manually unlocked without depending on the electric lock drive signal is determined. Alternatively, when a signal for opening the door such as a door on which the electric lock is installed is input to the electric lock controller 21, the warning indicator lamp 23 blinks and the buzzer 24 sounds. After that, when the alert button 22 is pressed, the sound of the buzzer 24 is stopped.

[0004]

However, in such an electric lock controller, a buzzer for issuing an alarm is provided only in the electric lock controller, so that the buzzer sound installed in the electric lock controller is audible. Warnings could only be issued in the area. For this reason, when there is no person near the electric lock controller, there is a drawback that the sound of the buzzer is not sensed and the alarm cannot be dealt with.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and can recognize an alarm issuance even at a place away from the electric lock controller at the time of an alarm issuance, thereby improving the crime prevention effect. It is an object to provide an electric lock control device.

[0006]

In order to attain this object, the electric lock control device of the present invention is set to an alarm mode when an alarm button is pressed, an alarm indicator is turned on, and the electric lock is manually unlocked or unlocked. The warning indicator flashes when the door is open,
If the door is unlocked, the unlock indicator light flashes.If the door is open, the door open indicator light flashes, the buzzer sounds and an alarm is issued. This is an electric lock control device in which the blinking is restored, the unlocking indicator light or the door opening indicator light is restored, and the buzzer sounds are restored.It is turned on when an alarm is issued and turned off when the alert button is pressed It comprises an alarm device contact circuit, and an alarm device which is activated when the alarm device contact circuit is turned on and issues an alarm, and stops the alarm emission when the alarm device contact circuit is turned off.

[0007]

When the warning mode is set by pressing the warning button, if the electric lock is unlocked or the door on which the electric lock is installed is opened regardless of the electric lock driving signal, an alarm is issued. The device contact circuit is turned on, and an alarm is issued from the alarm device. Thereafter, when the alert button is pressed, the alarm device contact circuit is turned off, and the alarm issuance by the alarm device is stopped. By providing an alarm device in each place, the range where the alarm is not notified is eliminated, and in any place,
Can respond to crime prevention.
