1、 Introduction to indoor smoke detection transmitter

The BYC100-YW indoor smoke detection transmitter is a device developed and produced by Shenzhen Boyunchuang Environmental Technology Co., Ltd. for indoor air quality. It is mainly used to measure the content of smoke gases in indoor air, provide effective smoke concentration data, remind users to take safety measures, and drive functions such as fresh air system linkage and sprinkler system to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. The product is widely used in building HVAC, building energy conservation, smart homes, underground garages, airport stations, gas, petroleum, chemical, metallurgical and other places.

2、 Characteristics of indoor smoke detection transmitter

4、 Installation of indoor smoke detection transmitter size

1. First, fix the installation disk on the wall.

2. After connecting the equipment, fix it on the installation disk.

3. Do not connect the transmitter to a voltage higher than 24VDC. To prevent excessive voltage from burning out the sensor.

4. Install the transmitter at the location that needs to be tested, away from the heating element or steam source, and prevent direct sunlight.
