Supply of household carbon monoxide alarm, carbon monoxide poisoning alarms soot carbon monoxide alarm price is a carbon monoxide alarm detection and alarm system capable of detecting carbon monoxide in the air space measured and alarms. Including the use of electrochemical electrode principle, catalytic combustion principle and the principle of semiconductor gas CO concentration in the environment is detected, usually by the sensors and secondary instrument. Necessity carbon monoxide alarm: carbon monoxide by fuels (such as gasoline, diesel fuel, coal, charcoal, gas, liquefied petroleum gas, natural gas, etc.) produced by incomplete combustion. Main causes of carbon monoxide in the home: natural gas, coal gas, liquefied petroleum gas, fuel, incomplete combustion of coal; improperly installed water heater, exhaust gas recirculation; chimney, exhaust pipe blocked; confined spaces open, fire heating, such as driving engine in the garage winter closed doors the stove for heating and so on. Carbon monoxide (CO) gas is a colorless, odorless, non-irritating, can not sense perception of toxic gas, can inhibit the oxygen carrying capacity of the blood. Carbon monoxide toxicity mainly affect the supply and utilization of oxygen affinity of carbon monoxide and oxygen in red blood cells and red blood cells than the affinity of 300 times more than large, resulting in tissue hypoxia. When inhaled carbon monoxide gas, carbon monoxide enters the lungs and blood erythrocyte binding pre-empt that red blood cells lose the ability to transport oxygen, causing the body of oxygen, leading to tissue damage and even death. Most people can not self-aware in case of accidental poisoning, often has entered a coma was found, causing death or serious injury. So the family called the "invisible killer", a little too much. For family and security factories, schools and other places, the installation of carbon monoxide is essential. Carbon monoxide alarm carbon monoxide alarm is the principle of concentration of carbon monoxide gas into electrical signals induced by carbon monoxide sensors in the air, the size of the electrical signal with the concentration of carbon monoxide related. Carbon monoxide sensors There are many, according to the principle can be divided into semiconductor carbon monoxide sensor, electrochemical carbon monoxide sensor, an infrared carbon monoxide sensors. Carbon monoxide and carbon monoxide mass concentration sensor output corresponding electrical signals, once the signal reaches dangerous content, alarm system will work, people around tips to take timely measures. The main component carbon monoxide alarm "Test" (test) button This button is to test the alarm time according to the button. Vent carbon monoxide gas entering through the gap between the shell and the bottom shell surface alarm sensing chamber Sensor application of electrochemical techniques, high sensitivity to carbon monoxide sensors, and avoid the occurrence of false alarms. Buzzer loud, vocal remind people around watch out for hazards. Carbon monoxide alarm the main parameters Operating voltage: AC220 V ± 20 [%], 50HZ measuring range: 0 ~ 100 [%] LEL / 0 ~ 990ppm / 0 ~ 99ppm alarm output: 220v 3A normally open Alarm volume: ≥85dB Power : ≤15W Operating temperature: -20 ℃ ~ + 60 ℃ Humidity: ≤90 [%] RH Backup power usage time: ≥1.5h Cable: 3 * 0.5 sheathed cable transmission distance: 1500 meters
