Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention monitors the opening and closing and the door lock by an illegal intruder such as a plurality of doors in a store or a building, and automatically detects that the door is opened by an illegal intruder. To inform,
You can set multiple signal lines with security sensors connected to each other at the same time by operating one remote controller, or you can set the alarm set / release for each line, and if the alarm set is not set normally, or there is an abnormality in the door lock. The present invention relates to a crime prevention reception system having a new configuration that enables the remote controller to determine the abnormality if there is.

[0002]

2. Description of the Related Art In this type of security receiver system, a security mode that outputs an alarm when an abnormal signal is detected from a security sensor is set in the security receiver mainly at night.
In other time zones, it is switched to the warning release mode in which the alarm is not output even if an abnormal signal is received from the security sensor. There is a security receiver equipped with a remote warning input terminal that can switch this setting from the outside by remote operation.
It is conceivable that this remote operation is performed using a commercially available key switch, but this key switch has a configuration in which a set current flows through the set switch unit to turn on the display LED. On the other hand, the security receiver derives multiple signal lines to which security sensors are connected, but these multiple signal lines are connected in parallel to a single key switch to set the alert set and the alert release switch all at once. If it is configured so that the current increases as the number of connections increases, the LED is destroyed. Therefore, when performing remote setting / release of each line of the security receiver by remote control, prepare the number of normally open contact output devices corresponding to each signal line, and connect these normally open contact output devices to the security receiver. Each remote signal input section is individually connected. Therefore, it is necessary to install the same number of normally open contact output devices in parallel according to the number of signal lines, resulting in an increase in the number of parts and an increase in the size of the entire device, as well as an increase in cost.

Further, when each signal line of the crime prevention receiver is set to the guard set by the remote operation described above, if each signal line is not normally set to the guard set or there is an abnormality in the door lock, the crime prevention reception is performed. On the machine side, it can be known by a warning sound or display that informs of the abnormality, but on the side of the remote controller it is not understood. Therefore, it is possible to install an additional speaker or to connect each warning set output terminal provided in the crime prevention receiver corresponding to the signal line with an indicator composed of an LED or a lamp. . Also in this case, the number of parts is increased, the size of the entire apparatus is increased, and the cost is increased.

[0004]

SUMMARY OF THE INVENTION An object of the present invention, which is proposed in view of the above circumstances, is to set a guard set / set for a plurality of signal lines.

Next, only the configuration different from that of FIG. 3 will be described. Equipped with a number of warning set / release switches SW11 to SW1n corresponding to the signal lines S1 to Sn and interlocking switches SW21 to SW2n interlocked with them, and each of the warning set / release switches SW11 to SW1 is connected to a common set RCO terminal It is individually inserted and connected between each of the corresponding guard set output terminals R1 to Rn. On the other hand, each interlocking contact SW
21 to SW2n are individually inserted and connected between the warning set output common terminal RCO and the corresponding operation indicator lamps L1 to Ln.

In this embodiment, a plurality of signal lines S1 to S are provided.
Instead of simultaneously setting the warning set or cancellation of n as in the first and second embodiments, each signal line S1 to S
It can be set individually for each n. Therefore, if necessary, only the specific signal lines S1 to Sn are held in the released state, or the specific signal lines S1 to Sn are held.
Only the alert set can be set.

[0022]

As can be understood from the above description, according to the security receiver system of the present invention, a plurality of signals of the security receiver can be operated by operating the warning set / release switch provided on a single remote controller. It is possible to set the line alert set / cancel switching settings all at once. Therefore, compared to the conventional configuration in which the normally open contact output device is individually connected to each remote signal input section of the crime prevention receiver, the number of parts is significantly reduced, downsizing of the entire system and cost reduction. Can be achieved.

Further, the operation indicator lights provided corresponding to the respective signal lines are individually output from the warning set confirmation output terminals provided corresponding to the signal lines when the signal line is normally set to the warning set. Since it is configured to light up by using the warning set confirmation signal described above, it is possible to know the signal line which is not normally set in the warning set in the remote controller. Here, if the door lock notification alarm circuit is connected to the operation indicator lamp, a function of detecting whether the door lock is correct or not can be added to each signal line. Furthermore, if the alarm set / release switch and the interlocking contact that is interlocked with this switch are individually provided for each signal line, it is not necessary to set the alarm set or release for multiple signal lines all at once. It can be set individually for each signal line.
