Shenzhen Lidingfeng Technology Co., Ltd. is based in China and lists smoke detectors, carbon monoxide detectors and combustible gas detectors on Global Trade Plaza. The smoke detectors use an intelligent MCU to process photoelectronic signals and include dust-proof, mothproof and anti-light interference functions. They react quickly to visible smoke from smoldering and flaming fires and are intended for houses, factories, shopping malls, hotels, restaurants, office buildings, teaching buildings, banks, libraries and warehouses. The carbon monoxide detector is battery-operated with a backlit digital display showing levels from 001 to 999 PPM. It provides LED and buzzer alarms at defined concentration thresholds and is suited for villas, factories, shopping malls, warehouses and office buildings. The combustible gas detector uses a catalytic combustion sensor with voice prompt and microprocessor control to display gas concentration, targeting liquefied petroleum gas, natural gas and methane.
