Gas leak detector fittings

■Overview of Cockroach Sealing Hole 1. It consists of a mounting frame and a lid, with the lid fitted with ceiling finishing material, and the mounting frame can be attached to the ceiling finishing material, serving as a cockroach sealing hole (round inspection opening). 2. A hole is drilled in the ceiling finishing material from indoors, and the cockroach sealing hole is fitted and installed into that hole. 3. Cockroach sealing holes are installed in the ceilings of kitchens, cooking areas, and food preparation areas. 4. By opening the lid of the cockroach sealing hole, hands or arms can be inserted through the hole into the ceiling space to place extermination supplies (such as insecticides, rodenticides, various traps, and cockroach or rat baits) from indoors into the ceiling space or behind the lid. 5. For example, in kitchens or cooking areas, even if insecticides (fumigants) like Valsan are used indoors, cockroaches escape into the ceiling space or under the floor. Additionally, cockroaches and rats typically hide in the ceiling space or under the floor. 6. Cockroach sealing holes and cockroach floor holes are provided in the ceiling space and under the floor, allowing extermination supplies to be installed in those areas for pest control. 7. In this way, cockroaches and rats hiding in the ceiling space or under the floor, which can lead to mass food poisoning, can be exterminated, allowing for safe cooking and dining.

■Overview of Gas Leak Detector Mounting Hardware 1. It consists of a mounting frame and a cover, with the ceiling finishing material fitted into the cover and a stand combined with the mounting frame for the gas leak detector hardware. 2. The gas leak detector is mounted on the stand of the gas leak detector hardware. 3. A hole is drilled in the ceiling finishing material, and the gas leak detector hardware is inserted into that hole and attached to the ceiling finishing material. Additionally, a cable catcher or arm is inserted through the hole to run and connect the power and signal wires in the ceiling space. 4. The finishing material with a hole is fitted into the cover, and the cover is secured into the mounting frame of the main unit, completing the installation. 5. The cover can be opened, allowing for easy gas leak testing and inspection of the gas leak detector from inside the room. 6. For example, if a gas leak occurs in the ceiling space of a building, the gas leak detector in the ceiling space will detect the leak and trigger a gas leak alarm. It will also notify via a relay signal. 7. In this way, gas leaks in the ceiling space of a building can be detected early, preventing potential fires associated with gas leaks.

■Overview of Firefighting Sealing Hole 1. It consists of a mounting frame and a cover, with the cover fitted with ceiling finishing material, and the mounting frame can be attached to the ceiling finishing material. A sprinkler head is attached to the cover. 2. A hole is made in the ceiling, and the firefighting sealing hole is inserted into that hole and attached to the ceiling finishing material. Additionally, a cable catcher or arm can be inserted through the hole to facilitate piping and wiring in the ceiling space. 3. The finishing material with a hole is fitted into the cover, and the sprinkler head is attached to the cover. The cover is then fitted into the mounting frame of the main body, completing the installation. 4. The cover can be removed or rotated, allowing for free adjustment and replacement of the head's direction. 5. After the ceiling work is completed, piping and wiring in the ceiling space, as well as the installation of the head, can be done from inside the room, leading to reduced construction time, lower costs, and safer work conditions. 6. Confirmation and inspection of the connections in the ceiling space can be easily done from inside the room, making maintenance tasks easier. 7. It does not involve exposed wiring, preserving the building's image, and provides a good finish and appearance. 8. Thus, facilitating the piping, wiring, and installation of sprinkler systems without hindering the building is an extremely innovative method for renovations, expansions, renewals, and new constructions.

The security sealing hole consists of a mounting frame and a cover, with the ceiling finishing material fitted into the cover. Security surveillance cameras and security sensors can be mounted on this cover, while the mounting frame is attached to the ceiling finishing material. Wires can be easily routed through the ceiling space or wall from the opening of the cover. In other words, by installing the security sealing hole in the ceiling and opening the cover, one can insert a cable catcher or arm through the hole into the ceiling space to run wires from indoors to the ceiling, connecting them to the security surveillance cameras or sensors mounted on the cover. For example, one can insert a cable catcher (structured like a fishing rod) through one security sealing hole into the ceiling space and extend it, then hook a wire onto the tip from the other security sealing hole and pull the cable catcher back, allowing the wire to be routed in the ceiling space. Additionally, connections can be made to the security surveillance cameras or sensors mounted on the cover. In this way, simplifying the wiring for security equipment installation and the mounting of security surveillance cameras and sensors without disrupting the building is an extremely innovative method for conducting security operations.
