There is an alarm device that centrally monitors the monitoring area for the presence or absence of an abnormality in a security area.

In such an alarm device, the security area is divided into a plurality of blocks, and each block is provided with a sensor for detecting an abnormality such as theft, gas leak, or fire, and the monitoring center monitors each block. I have something to do. When the security area is divided into multiple blocks in this way, when a visitor who is admitted to enter only a predetermined block tries to enter the predetermined block in the security area, it passes by before going to that block. The common block such as the corridor, elevator hall, entrance, etc. was changed from the monitored state to the released state.

[0004]

However, according to this conventional method, the block intended by the visitor and the common block such as the corridor, elevator hall, entrance, etc. through which the block reaches the block are also released. Moreover, even if a thief intrudes from this common block while the visitors are in the predetermined block, it cannot be grasped by the surveillance center because it is in the released state. Furthermore, since the regular visitors in the predetermined block cannot know the invasion of the bandits, they will be attacked and their safety will be threatened.

The present invention has been made in view of the above problems, and in an alarm device for monitoring a security area divided into a plurality of blocks, when the visitor enters the security area in the monitoring state, Unrelated blocks can be kept in a monitoring state, and shared blocks that visitors pass through are in a released state when visitors pass through, but are automatically in a monitoring state in other cases. By doing so, it is intended to regulate the behavior of visitors and to ensure the safety of regular visitors.

[0006]

In order to achieve the above object, the present invention provides a plurality of sensors installed in a security area divided into a plurality of blocks and a monitoring center when an abnormal signal from the sensors is received. In the alarm device having a controller for performing, the controller is provided with a state setting means and a clocking means.

The state setting means sets a monitoring state or a release state for each of the blocks, outputs a time count start signal when a plurality of specific blocks among the plurality of blocks are set to the release state, and outputs a time count start signal. When the end signal is received, a predetermined block of the specific plurality of blocks set to the release state is set to the monitoring state. The clocking means starts clocking when the clocking start signal is input, and outputs the clocking end signal when a set time has elapsed.

Furthermore, the present invention provides the above controller,
Display means may be provided for displaying an abnormality when the sensor detects an abnormality.

[0009]

[Operation] When a visitor enters the security area that is being monitored, the controller changes the blocks required for the visitor's purpose to the unlocked state by the operation of the visitor, and the other blocks remain in the monitoring state. And As a result, the monitoring center can detect that the visitor has entered an unnecessary block, and can regulate the activity range of the visitor.

Further, the timekeeping means is such that, when the visitor enters the security area under the monitoring state, from the operation of entering the building to the arrival at the block for the purpose of admission and / or from the block where the visitor finishes the work and is set to the release state It counts the time necessary and sufficient to exit, and sets the block to the monitoring state after counting up. As a result, it is possible to put a block in which no legitimate visitor is in a monitoring state, and even if a bandit enters the security area, the monitoring center can immediately recognize this.

Further, by providing the controller with a display device, an authorized visitor can know that a bandit has entered the security area and can promptly take action against the bandit.
