The carbon dioxide alarm detector, also known as the fixed carbon dioxide alarm, is composed of a gas controller and a carbon dioxide detector. It is powered on after being connected by cables and can effectively detect the content of carbon dioxide in the air. The carbon dioxide alarm detector is installed on the detection site, and the gas controller is mostly installed in the central control room or duty room and other places. The carbon dioxide detector can transmit the detected carbon dioxide gas to the gas controller in the form of electrical signal, and the gas control will be converted to display it in the form of numerical value.
When the concentration of carbon dioxide gas in the air exceeds the standard, the instrument will send an audible and visual alarm to remind the user to take safety measures. In addition, where there is carbon dioxide gas and it is not suitable to install a fixed carbon dioxide alarm, a carbon dioxide alarm detector shall be equipped for routine inspection.
