Otywell | Gas Detector Manufacturer
Description
GDB11 gas alarm controller mainly receives the detection data of on-site gas detectors. When the preset alarm value is reached or exceeded, it will immediately send out sound and light alarms to remind the safety personnel to take safety measures in time. At the same time, it will automatically start the on-site fan or cut off the gas source to prevent poisoning/explosion and fire, thereby protecting the lives of personnel and the property safety of enterprises.
