Description

[Detailed description of the invention] [Industrial application field]

The present invention provides a crime prevention system that includes a key box for storing the keys of each room, and also includes a key switch in each key box so that the operation of a security sensor installed in each room can be turned on and off using the key of each room. It's about systems.

2. Description of the Related Art Generally, the key to a room in a tenanted building is carried by the user of the room only while the room is being used. For example, when employees are dispatched to work, they take the room key out of a key box in the control room, and when they leave the office, they return the key to the key box. In this case, the key is normally managed by a caretaker or the like to prevent anyone other than the person using the room from using the key, but the problem is that management is troublesome and mistakes are likely to occur. There is. Therefore, as shown in FIG. 5, it has been considered to provide a management panel 2 equipped with a plurality of key boxes 6, to 6n in which keys can be stored in each room. Each key box 6I~6n
is provided with doors 51 to 5n, which are opened only when the user of the room is confirmed by a magnetic card league. That is, each user of each room is given a magnetic card with an individual identification code written on it, and when this magnetic card is inserted into the slot S of the magnetic card reader provided in the management panel 2 and slid, the identification code is read. Compatible door 51
Only ~5n opens. In this way, only the occupant of the room can take out the key from the corresponding key box 6I-6n. After taking out the key, open the door 5. ~5
If you close n, door 5. ~5n is locked. On the other hand, each room is usually equipped with a security sensor, but when the user is using the room, the security sensor is not necessary, so keys are stored in the key boxes 6, - 6n. It is reasonable to operate security sensors only occasionally. Therefore, a security system has been proposed in which a key switch that can turn on and off the operation of the security sensor is provided in the key box 6, to 6n, and the key used to operate the key switch is also used as a room key. That is, if the key is inserted and operated in the key switch in the key box 6, ~6n, the security sensor is activated, and the key can then be stored by closing the door 51~5n of the key box 6, ~6n. This is possible. Also, to take out the keys, use the magnetic card from the doors 5. of the key boxes 61 to 6n. ~5n
After opening the door and operating the key switch, you can turn off the security sensor by removing the key.

[Problem to be solved by the invention]

By the way, in tenant buildings and the like, the room assignments of users may be changed. For example, four rooms may initially be used by different users, and later three of the rooms may be used by one user. In the conventional configuration described above, when the room allocation is changed such that one user uses three rooms, the users of these rooms must operate the key switches for each of the three key boxes 6° to 6n. The operation was troublesome. Also, if the wall separating three rooms is removed and used as one room, and the room has three doors,
Although it is normal to close two doors from the inside and the remaining door from the outside of the room, there was the inconvenience of having to operate three key switches. Such problems become even more serious as the number of rooms used by one user increases. Therefore, when the room allocation of users changes, it is considered to change the wiring so that security sensors II to 13 in the room used by one user are connected in series, as shown in Figure 6. . That is, security sensor 1. ~1. is on-
It is configured to obtain an OFF contact output, and is set so that an OFF output is obtained upon detection. Therefore, if they are connected in series, the security sensors in the three rooms can be turned on and off with just one key switch. However, changing the wiring in this way requires work to change the wiring, and there is a problem in that it takes a lot of time and effort to change. The present invention aims to solve the above problem, and when a user uses multiple rooms, the user can access all the rooms by using only one of the key boxes corresponding to each room. A crime prevention system that allows the security sensor to be turned on and off, and also allows the correspondence between the key switch and the security sensor to be changed without any work such as wiring changes when the user's room assignment changes. The aim is to provide a system.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a plurality of key boxes that individually store the keys of a plurality of rooms, and a plurality of key boxes that are arranged in each key box and that are turned on and off by the keys of the corresponding rooms. It has a control panel with key switches and security sensors installed in each room.
Each key box has an alarm device that generates an alarm in response to the output of each security sensor corresponding to each key switch when a key is inserted and turned on. Each door is equipped with a door that can be opened and closed individually, and a key switch is installed inside the door, and a connection device is installed between each key switch and each security sensor in the control panel so that the correspondence relationship can be changed. There is. In addition, the first line group corresponds to each key switch and the 21st line group corresponds to each security sensor! The lines are arranged in a grid pattern so as to cross each other, and the connecting device has a plurality of two-pole terminals each connected to a pair of lines forming each intersection of the first line group and the second line group. It is desirable to provide a plurality of short-circuiters that are detachably connected to the terminal so as to electrically short-circuit between the two poles of any given terminal. Furthermore, the output of each security sensor is set as a contact output that selects between two states, on and off, so that an off output is obtained when detected, and each line of the first line group of the connection device is connected to one end of the power supply. Connect a relay between each, and connect the second
A normally closed contact that turns on when it receives an off output from the security sensor is connected to each track in the track group to the other end of the power supply, and when a key is inserted into each key switch and turned on, each It is desirable to drive the alarm device in response to the open/close states of the contacts of each of the relays, which correspond one-to-one to the key switch.

[Effect]

According to the above configuration, since a connection device is provided that can change the correspondence relationship between the key switch and the security sensor, the connection device can collectively manage the correspondence relationship between the key switch and the security sensor. When a person uses multiple rooms, it is easy to set up a connection manager that allows security sensors in all rooms to be turned on and off using only one of the key boxes corresponding to each room. It will become. Moreover, even when the user's room assignment changes, all you have to do is set the correspondence between the key switch and security sensor using the connection device, so there is no need to change the wiring or other construction work to connect the key switch and security sensor. The correspondence relationship can be easily changed. In addition, the first line group corresponding to each key switch and the second line group corresponding to each security sensor are wired in a grid pattern so as to cross each other, and the first line group and second line group are connected to the connecting device. A plurality of two-pole terminals each connected to a pair of lines forming each intersection with the terminal are provided, and a plurality of shorting elements are detachably connected to the terminal so as to electrically short-circuit between the two poles of any terminal. By providing this, the correspondence relationship between the key switch and the security sensor can be easily changed by changing the position of the short circuit. Furthermore, the output of each security sensor is set as a contact output that selects between two states, on and off, so that an off output is obtained when detected, and each line of the first line group of the connection device is connected to one end of the power supply. Connect a relay between each, and connect the second
A normally closed contact that turns on when it receives an off output from the security sensor is connected to each track in the track group to the other end of the power supply, and when a key is inserted into each key switch and turned on, each If the alarm device is activated in response to the open/closed state of the normally closed contacts of each relay that corresponds one-to-one to the key switch, even if the line between the security sensor and the control panel is disconnected, the security sensor will not disable the alarm. Since the alarm device can be driven in the same way as the off output, an alarm can be generated even when an intruder cuts the line.
