[0004]

By the way, in the above-mentioned conventional crime prevention / disaster prevention system, due to an earthquake or the like, there is a fire between the receiver 2 and the detectors 3 ₁ , 3 ₂ , 3 ₃ ,. , 6n when the receiver 5 and the detectors 6 ₁ , 6 ₂ , ..., 6n are disconnected, due to a power failure, disconnection of the power cord, or the like.
Also, there is a problem that when the power is not supplied to the fire receiver 5, the fire receiver 5 does not play any role as a facility at all.

In addition, the conventional crime prevention / disaster prevention system only detects and reports anomalies such as fire, gas leakage, intrusion, etc., and detectors may be installed at various places in the building to prevent crime and disaster prevention. It is also desired to utilize it for other purposes. For example,
Since the emergency light is installed in the building separately from the crime prevention / disaster prevention system, it is not preferable in terms of labor saving and cost reduction during construction. By adding the function of an emergency light to a crime prevention / disaster prevention system, it is possible to save labor during construction and reduce costs. In this case, the detector of the crime prevention / disaster prevention system is always installed in each room in the building, so by providing it with the function of an emergency light, it is possible to illuminate a wider area than when using only an emergency light. It is possible to ensure sufficient safety in the event of a disaster. Conventional emergency lights include those equipped with a pyroelectric sensor that automatically light up when a person approaches, or those that plug into an outlet and automatically light up during a power failure.

The present invention has been made in view of the above-mentioned circumstances, and the power supply to the receiver is interrupted due to disconnection of the wiring between the receiver and the detector due to a disaster, power failure, disconnection of the power cord, or the like. Security that can be used as an emergency light even when
The purpose is to provide a disaster prevention system.

[0007]

To achieve this object, the crime prevention / disaster prevention system according to the present invention is a report table for displaying a report when an abnormality such as intrusion, fire, gas leak or earthquake is detected.
A detector having a示灯, are connected by the detector and the wire, in crime and disaster prevention system comprising a receiver which outputs an alarm by the alarm of the detector, the said detector
A lighting means is also provided for turning on the alarm indicator lamp also as an emergency light, and shutting down commercial power to the receiver, earthquake,
In addition, a control means for turning on the illumination means when a specific signal is input from the outside is provided.

According to this structure, the illumination means of each detector is turned on when the commercial power supply to the receiver is interrupted, when the detector issues a warning, or when an earthquake occurs. Therefore, the crime prevention / disaster prevention system functions as an emergency light not only when there is an abnormality such as a fire, gas leak, or earthquake, but also when the power supply to the receiver is cut off. Can be sufficiently secured.

Further, in the case of alarm detectors it can also serve as alarm indicator the emergency lamp by turning on the illumination means at a low intensity, separately is not necessary to provide a very light, correspondingly, the cost Can suppress the rise of.

Further, if the ambient brightness is above a certain level, the lighting means is not turned on except for the alarm from the detector, and if the surrounding brightness is below a certain level, the lighting means is turned on with high brightness. By doing so, it is possible to save power without wasting power. In addition, each detector is equipped with a standby power supply,
By switching to the standby power supply when the wiring between the receiver and the detector is broken, it functions as an emergency light even if the wiring between the receiver and each detector is broken, so safety in the event of a disaster Can be sufficiently secured.
