How to install a carbon monoxide alarm

Carbon monoxide alarms can be divided into household carbon monoxide alarms and industrial carbon monoxide alarms according to the direction of use. In addition, they can be divided into wall-mounted/fixed carbon monoxide alarms and portable carbon monoxide alarms according to their usage. You can choose different according to your different requirements. Instrument.

Carbon monoxide (CO) gas is a colorless, odorless, non-irritating toxic gas that cannot be perceived by the five senses, and can inhibit the blood's ability to carry oxygen. The toxicity of carbon monoxide mainly affects the supply and utilization of oxygen. The affinity of carbon monoxide and red blood cells is more than 300 times greater than the affinity of oxygen and red blood cells, resulting in hypoxia in human tissues. When carbon monoxide gas is inhaled, carbon monoxide enters the lungs and combines with red blood cells first, causing the red blood cells to lose the ability to transport oxygen, resulting in hypoxia in many organs of the body, resulting in tissue damage and even death. Most people are unable to detect themselves when accidentally poisoned, and are often in a coma when they are found, causing serious injury or even death. Therefore, it is not too much to call it the "invisible killer" in the family.

Carbon monoxide production: Carbon monoxide is produced by insufficient combustion of fuels (such as gasoline, diesel, coal, charcoal, coal gas, liquefied gas, natural gas, etc.). The main causes of carbon monoxide production in the home: incomplete combustion of natural gas, coal gas, liquefied gas, fuel oil, coal; improper installation of water heaters, exhaust gas return; blockage of chimneys and exhaust pipes; closed spaces with engines and fires for heating, such as in a garage Engines, close doors and windows to make stoves for heating in winter, etc.

The carbon monoxide alarm converts the concentration of carbon monoxide gas in the air into an electrical signal through a carbon monoxide sensor. The size of the electrical signal is related to the concentration of carbon monoxide. Carbon monoxide alarms are classified according to the sensors used. They are generally divided into semiconductor carbon monoxide alarms, electrochemical carbon monoxide alarms, infrared carbon monoxide detectors, etc. The performance is the best in terms of measurement sensitivity, accuracy, stability, and resistance to cross-gas interference. This is an infrared carbon monoxide detector, but it is more expensive and suitable for laboratory use. The civilian ones are generally semiconductor and electrochemical carbon monoxide alarms.

How to install an alarm

Normal working characteristics

When the alarm is powered on, the red light will flash. Press the test button and the alarm will sound an alarm, indicating that the carbon monoxide alarm is powered on and the line is working. (When the power is turned on or the battery is changed, the alarm may sound, and it will return to normal after a few minutes.) When the voltage of the alarm is low, it will emit a "chirp" sound every 30 seconds to remind you that the power supply is insufficient, and you should replace the battery .

First, select the installation location of the alarm.

Then, fix the base to the wall or ceiling with the screws in the accessories provided with the alarm, then install the battery, and then screw the alarm to the base (note: align the bottom cover of the alarm with the horizontal bars on the base for convenience Screw the alarm to the base.)
