Supply HS-L808 electrical fire detectors Shu HS-L808 leakage protection

HS-L808 electrical fire detectors Product Overview For loads more important buildings, including fire-fighting equipment, security equipment, emergency lighting and evacuation lighting, power, etc. are not allowed off various types of equipment, according to GB 13955 - 2005 "Remaining current operated protective devices to install and run "requirement, you should install the alarm style electric fire detectors. Based on ARM7 microprocessor fire monitor system, fire alarm problem solving provides new solutions and approaches, both to improve the system's accuracy, reliability, but also for engineering design, construction layout provides a great convenience . In leakage current alarm threshold setting, it is usually not less than the alarm setpoint lines and equipment uptime twice the value of the leakage current and the rated residual operating current value should be adjusted in order to have inaccurate data or calculated error and change of use, can be adjusted within the appropriate range. In recent years, the rapid growth of China's national economy, the industry electricity consumption increased significantly, accompanied by an electrical fire also showed an increasing trend, to the national economy and people's lives and property caused huge losses, while the fire is the most common ground fault with multiple electrical fire.
