Carbon monoxide alarm preferred Yongkang brand alarm. Carbon monoxide poisoning is the product of the incomplete combustion of carbonaceous material when toxic by inhalation. Carbon monoxide poisoning mechanism of hemoglobin affinity than oxygen affinity with hemoglobin 200 to 300 times higher, so vulnerable to carbon monoxide combines with hemoglobin to form carboxyhemoglobin, hemoglobin oxygen-carrying capacity and role of the loss, resulting in tissue suffocation. Tissue cells were toxic effects on the body, especially the effect on the cerebral cortex of the most serious. Features: 1. Design as an independent gas chamber, can reduce response time and improve accuracy, the buzzer on the sensor detects no interference, the use of the air intake louvers reduce the direct impact of dust and soot sensor 2. The sound and light alarm and automatic output signal, easy to control external devices 3. Customize sensor: do film processing, the equivalent of fine mesh, can stop the particulate matter into the high sensitivity, good selectivity and reduce the false alarm rate. 4. Sensor 5. automatic fault detection alarm, alarm when the gas concentration is below the set value, the detector automatic reset Product Overview: This product is of high stability carbon monoxide alarm interior ceiling (hereinafter referred to as the alarm), alarm It uses a carbon monoxide concentration sensor converts the signal into the air of carbon monoxide gas weak current or voltage signal, and then through stage or two-stage signal amplification, transmitted to the microcontroller for signal processing compared with more than a predetermined threshold value the microcontroller audible alarm signal to drive LED lights, horn or buzzer. This product is used may produce carbon monoxide leak in indoor places. The dangers of carbon monoxide: Carbon monoxide gas is an invisible, colorless, odorless, non-irritating, can not use the five senses of gas. Carbon monoxide is a colorless, odorless, poisonous gas, acute poisoning: mild poisoning headache, dizziness, tinnitus, palpitations, nausea, vomiting, weakness; moderate poisoning addition to the above symptoms, there was cherry red skin and mucous membranes, rapid pulse, irritability, ataxia, light to moderate coma; severe patients with deep coma, restlessness, muscle tension, frequent seizures, incontinence, shock, pulmonary edema, severe myocardial damage. Carbon monoxide gas in the blood and cause tissue hypoxia and hemoglobin. Any fuel combustion produces: natural gas, oil, charcoal, and even tobacco. When burned in a limited air, it will produce more carbon monoxide; no proper ventilation to go to the house, the problem will become more serious. When inhaled carbon monoxide, and carbon monoxide gas through your blood erythrocyte binding. The role of red blood cells called hemoglobin, the red blood cells and oxygen combined 200 times faster, it will hinder oxygen into the vital parts of your heart, brain and so on. Because carbon monoxide accumulation in the blood, your body will lack of oxygen. That is why the importance of having a carbon monoxide alarm. Carbon monoxide alarm can be long-term work in explosive gas areas, and alarm controller supporting the use of real-time monitoring site gas concentration, concentration exceeding ensure that the first time an alarm signal, promptly eliminate hidden dangers. Alarm system is widely used in place of chemical, electricity pharmaceutical, metallurgy, coking industry and the production, storage, use gas. Carbon monoxide alarm features for the detection of high precision, stable performance, anti-toxic, anti-interference ability, reliable quality. Carbon monoxide alarm can effectively alert the user to take safety measures and drive the exhaust, cut, spray system to prevent an explosion, fire, poisoning, thereby protecting the safety of products are widely used in gas, petroleum, chemical, metallurgy and other presence acetylene, explosive, toxic gases in dangerous places. Technical parameters: Power supply: 3 AA batteries Operating Range: Temperature: -10 ℃ ~ 50 ℃ Relative Humidity: 25% to 85% of the alarm current: about 20mA monitor current: less than 35uA (can work for more than one year) Alarm sound: NOW 3 m in front of more than 85 db low voltage warning did not look voltage: 3V ± 0.3V standard alarm this alarm is designed according to EN20591: 50ppm60 ~ 90 Alarm minute; 100ppm 10 ~ 40 Alarm minute; 300ppm3 minute alarm installation considerations : (1) Alarm probe sensing element is mainly catalytic combustion gas sensor, a platinum wire coil wrapped in adhesive composition of alumina and the spherical outer surface with platinum, palladium and other precious metals. Therefore, the installation must be careful to avoid broken probe. (2) Alarm is safe instruments, sound, light display, should be installed in the staff easy to see and easy to hear the place, in order to promptly eliminate hidden dangers. Around (3) the alarm can not have an impact on the instrument working strong electromagnetic fields (such as high-power motors, transformers). (4) home installations should be noted that the installation location is not too close to the gas stoves, in order to avoid stove flame detector by baking; fumes can not be installed in large areas, in order to avoid false alarms or lead to an intake probe poor intake hole, thus affecting the detector sensor sensitivity; can not be installed on the exhaust fan, doors and windows at the side and a large bathroom moisture. (5) Figure correct wiring, all wiring installations must comply with valid national and local regulations, and standards. Improper connection will result in the event of a gas leak, not the normal police. Carbon monoxide alarm preferred Yongkang brand alarm. Need please contact me.
