The BJ-300 alarm uses an integrated circuit design with strong capabilities and stable operation as its core; The exterior is made of carbon steel plate material and coated with paint, with a novel and elegant structural design; The flash is made of a rotating police light, greatly enhancing the service life of the lamp tube; At the same time, the compact design of this series of products has advantages such as waterproofing, strong earthquake resistance, and easy installation. Product series models, users can choose tone, volume, and style according to their own usage scenarios and requirements. The penetrating power of sound in the air * (can still be heard clearly from 300 meters away) is bright and not harsh at close range, which can warn without harming human hearing. Simultaneously installed in one intermittent flash, it can emit dazzling strong light in sunlight, with better night effect. The characteristics of the BJ-300 alarm product are designed in combination with human physiological characteristics, with three different audio options to choose the best audio and volume, so that the sound can penetrate through the air * (can still be heard clearly from 300 meters away) and is bright and not harsh at close range, which can both warn and cause no harm to human hearing. It is connected to the conveyor belt sensor, which provides sound and light at the moment when the belt conveyor is about to have an accident, timely prompting on-site personnel to stop and deal with it, preventing material overflow and other faults caused by tape deviation, and preventing the expansion of accidents.

Integrated sound and light device&bsp< Precautions for using automatic sound and light devices: 1; Determine the toxic leakage direction when a large amount of leakage occurs based on factors such as airflow direction and wind direction in the location. 2. Based on the density of the leakage (greater or less than air), combined with the trend of air flow, a three-dimensional flow trend chart of the leakage is synthesized, and an initial point setting plan is made at the downstream position of its flow. 3. Is the leakage state of the leakage point micro leakage or jet like. If it is a minor leak, the location of the point should be closer to the leak point. If it is a jet leak, it should be kept slightly away from the leak point. Based on these situations, develop a final location plan. In this way, the quantity and variety that need to be purchased can be estimated. 4. For places with significant toxic leaks, according to relevant regulations, every 10& Mash: A detection point should be set up at 20m. For unmanned small and discontinuous pump rooms, attention should be paid to the possibility of toxic leakage, and generally one should be installed at the lower air outlet. 5. For locations with hydrogen gas leaks, they should be installed on a flat surface above the leak point& nbsp;
