Overview HA2200-01 sound and light alarm, a type of Ex d alarm equipment with sound and light indication, was used by matching with the industrial gas alarm detector. When the concentration value of target gas where the detector locates is higher than the set alarm value, the detector shall operate itself display alarm and relay dry contact alarm output. Simultaneously, it shall provide 24VDC power to the sound and light alarm which will send out strong sound and light alarm signal to admonish the site workers to take appropriate measures. Three kinds of gas we can detect: combustible gas, toxic gas and oxygen. The type of gas detector is Ex d, integrated with sound and light alarm together. While the space range needed alarm is not so large or the noise is not so excessive, it offers a kind of warning equipment with convenient installation. And no other additional alarm instruments needed. HA2200-01 sound and light alarm, with a strong, regular intermittent alarm sound and flash light indication, brings an effective warning function to the site workers. It can be widely used as gas detector alarm output elements in oil, natural gas mining, oil pipeline transportation, chemical engineering, oil house, metallurgical and mining industry, electricity, telecommunication, paper making, grain depot, water supply, sewage treatment.
