Abstract

(57) [Summary] [Purpose] The purpose is to supply fire detection alarms and other disaster prevention equipment to ordinary houses at low cost and to easily install them to increase the safety of life. [Structure] A device that uses 100V with a hooket rosette built-in structure that integrates sensing and notification. [Effect] Freed from expensive construction and large-scale construction, it has the effect of spreading disaster prevention equipment to ordinary households.

Description

[Detailed description of the device]

 [0001] [Industrial field of application] The present invention relates to a fire alarm or the like which is used by being attached to the ceiling of a general house, and more specifically, can be easily attached to an existing hanging rosette for attaching lighting equipment. It is a disaster prevention device with various functions. [0002] [Prior Art] Conventionally, as a disaster prevention device of this kind, a small sensor, mainly a control panel, is installed in each room or corridor to monitor fire, smoke, gas, etc. The device is known. In addition, inexpensive small fire detectors that use batteries as power sources are also known. [Problems to be Solved by the Invention] Among the problems described in the related art, the former is not suitable for general houses due to the large scale of the device, and the wiring work is difficult when installed in an existing building. Therefore, it is necessary to incorporate equipment installation at the building design stage. However, it is an important condition to realize the purpose that disaster prevention equipment can be easily installed. Further, in the latter, since the power source is a battery type, it is necessary to regularly replace the battery, and if the battery is not replaced, the function as a disaster prevention device will be lost. In addition, the volume of the alarm sound is also limited. A stable power supply is essential for the reliability and function of disaster prevention equipment. The present invention has been made in view of such problems of the conventional technology, and its purpose is to realize easy attachment to each room of an existing house and stable for long-term reliability acquisition. 100V power supply. [0006] [Means for Solving the Problems] In order to achieve the above object, the fire detection and alarm device according to the present invention is to be installed on a hook rosette that is widely used for mounting lighting equipment in an existing house. In order to make it possible to mount it without needing to install it, the main body of the main body is recessed in a circular shape, and there is a hooking rosette projection on it, and the center of the lower part is a recess for hooking a hanging rosette for lighting equipment. Equipped with rosette. FIG. 1 is a sectional view of the mounting. Easy to mount on the ceiling (7). [0007] By using the existing rosette, no special work is required to supply 100V power, and the lighting equipment used can also be hooked on the rosette at the bottom of the main unit and continued to be used. . [0008] In addition, from the fact that it is ideal to install it on the ceiling or central part of the room because of the function of the fire detector, it is judged that the rosette is installed in the central part of the ceiling, and the mounting position is satisfactory. It is possible. If it can be easily and inexpensively installed in each room such as a living room, bedroom, and kitchen, its presence as a disaster prevention device will increase accordingly.

[0009] Since the rosette power supply can be used as it is, there is no need to replace batteries, long-term, stable reliability, which is the mission of disaster prevention equipment, can be obtained, and 100 V power supply can realize a sufficient volume of warning sound. . [0010] [Operation] Since the individual main body independently emits an alarm sound, the position where a fire or the like is generated can be confirmed by the position of the sound. In a building such as a general house, it is desirable that the location of the fire and the location of the alarm sound are the same, but it is more desirable that only one alarm sound is heard throughout the building and has a volume that wakes the sleeping person. Will. If you can easily install a large number of sensing and alarm devices, you can do that. [Example] An example will be described with reference to the drawings. The upper part of the body (5) is circularly recessed, and the convex rosette (2) is fixed in the recess. The convex rosette is a structure that is electrically directly connected to the lower concave rosette, and sends electricity to the luminaire. In addition, the power supply to the sensing and notification devices inside the main unit is taken out from the rosette in parallel connection. The upper recess covers the existing rosette and is installed as close as possible to the ceiling. [0012] By making the main body into a bowl shape, the ceiling does not feel uncomfortable. By making a small convex part (9) on the side surface, it has a function of preventing slippage during installation. [0013] [Effect of the Invention] Since the present invention is configured as described above, it has the following effects. [0014] Since the upper and lower parts of the main body have rosettes, they can be installed directly on the existing rosettes on the ceiling, and since the lighting fixtures can also be installed at the same positions, large scale equipment with disaster prevention equipment and difficulty in construction Relieving the image, many disaster prevention devices can be installed easily and inexpensively in ordinary households. [0015] Since a 100V power source is used, the reliability is improved as compared with the battery type, and the function as a disaster prevention device is easily exhibited. [0016] Since it has a shape that covers the existing rosette, it is also excellent in appearance.
