Choose a reasonable installation location for alarm equipment
In addition to the television and broadcasting systems, the civil air defense department is responsible for selecting the installation and regulation of alarm equipment. Civil television, broadcasting, and communication enterprises play an auxiliary role, responsible for the debugging and port maintenance of alarm system auxiliary equipment, selecting suitable installation locations and computer room locations to ensure smooth installation. The selection of address should pay attention to the following points:
Firstly, the height of the selected layout building should be ensured to be appropriate.
Secondly, the selected placement location can be properly managed. Thirdly, the overall layout of the location is reasonable.
Fourthly, if the selected location is an independent room, the room size cannot be less than 10 square meters.
Fifthly, the installation of equipment requires attention to the configuration of the power supply and reinforcement of the installed basic components.
The location selection of installation equipment needs to be based on planning. When installing alarm equipment and determining the coverage range of sound, special attention should be paid to the matching relationship between the installation area and the motor.
Specific requirements for installing equipment
After years of practice, it has been concluded that when installing alarm equipment, it is necessary to confirm that the motor winding meets the requirements according to corresponding standards to ensure that its insulation resistance meets safety standards. Due to the need for short-circuit protection in the power supply, the current should be ensured to be less than 7 times the fixed multiple of the rated current and greater than 5 times. The support of the alarm equipment should meet safety requirements and undergo rust prevention treatment. The equipment needs to be installed and debugged to confirm that the bottom welding is firm.
It is necessary to note that the connecting wires between the power supply and the motor are firm and reliable, and the grounding device is installed firmly. The nut of the power supply machine's junction box needs to be installed tightly to ensure that the junction box cover is sealed tightly. The power cord needs to be fixed with cables or steel wires outdoors, and fixed with wire clamps indoors. At the same time, it is also necessary to ensure that appropriate waterproof and lightning protection equipment is equipped.
