[Action]

 The fire / water / gas leak detection / alarm device of the present invention selectively controls the operation of each sensor and alarm with its electric circuit, and the storage box accommodates this electric circuit. Combine sensors and alarms into one component. Furthermore, the device, which is packaged into a single component in a storage box, is moved to the site by transportation means, and each sensor and detector is installed in the proper place on the site.

The detector deals with various risks associated with on-site work by a combination of two or more detectors arbitrarily selected from a fire detector, a water leak detector, a gas leak detector, and the like. The sensor is installed in a place with a high ceiling or wall to detect light gas such as smoke or city gas due to fire, or installed in a place with a low floor or wall to prevent heavy gas such as propane gas or water leakage. To detect. Further, the sensor is installed at a high position by expanding and contracting the support arm, or the sensor is installed behind an obstacle by bending the support arm.

The support arm has a telescopic structure that can be telescopically extended, and can be held in an extended state by a holding means. The alarm device, when a signal from the sensor is received by wire or wirelessly when a fire, water leak, gas leak or the like occurs, emits light or sound to inform the surroundings of the abnormality. The alarm device is installed on the side wall of the aisle in the building to notify workers at other places away from the site of the abnormality. Further, a part of the alarm device is installed on the outer surface of the storage box at the site to make workers near the site notice abnormalities early.

At this time, if noise is generated due to work, it is desirable that a warning by a special sound is accompanied by a warning by light emission. Furthermore, by connecting the electric circuit to the alarm circuit of the existing disaster prevention panel and linking it with the alarm device of the guard room or the entire building, it is possible to notify the abnormality in the entire area of the building and promptly take emergency measures. Urge. The electric circuit controls the sensor, and when the sensor detects an abnormality such as a fire, water leak, or gas leak, receives a signal from the sensor to drive the alarm device.

There are various modes of power supply for the electric circuit, and when a commercial power supply is used, the power is supplied by inserting the plug into an outlet already installed in the building. Also, a battery can be used, in which case it is sufficient to turn on the power switch. Further, it goes without saying that an external storage battery can be used. In some cases, an emergency power supply is provided in response to an unexpected accident such as a power outage, and in this case, the electric circuit is switched to an emergency power supply by a storage battery at the same time when the normal power supply is stopped.

When the electric circuit and the alarm device are connected by radio such as radio waves or light, the transmission range is expanded because there is no code. The error action of the alarm due to other signal noise is controlled by the signal filter. The storage box stores the electric circuit including the power source, shields the electric circuit from external electric noise, and prevents error. In addition, the equipment for mounting the sensor and the alarm device will be stored to deal with mounting in place, and the fire extinguisher will be stored to deal with the initial fire extinguishing in the field. Further, by accommodating the sensor, the alarm, the supporting arm, the cord and the like in the storage box, the entire apparatus becomes compact.

Further, the present apparatus can be moved to the installation site on the site at the time of use by the transportation means including either or both of the wheel and the handle. The carrying means has various modes corresponding to the size and weight of the storage box. For example, when the storage box is heavy or large, the storage box is a side surface of the storage box. It is moved by using the handle provided on the and the wheels provided on the bottom surface of the storage box. Further, when the storage box is light or small, the storage box is lifted by the handles provided at two places on the upper surface of the storage box and is carried around.
