Household flammable gas detection (carbon monoxide)

            1、Operating Instructions

                      (1) After the alarm is powered on, the voice prompt "Welcome to carbon monoxide alarm", the LCD backlight will be on for 15 seconds, the LCD screen will decrease from 120 to 0, the preheating is over, the alarm will enter the fault detection state, and the detection will enter the normal detection state. The green indicator light is always on in the external power supply mode, and flashes every 8 seconds in the battery power supply mode, indicating that the alarm is in normal standby. In the Chinese voice state, when the concentration of the measured gas in the air is greater than 30PPM, the LCD display backlight will be on for 15 seconds, and the LCD screen backlight will be on for 15 seconds after it exceeds 70PPM. When switching to the English voice state, the LCD screen corresponds to the EN50291 alarm concentration. 25% delay display of the response time, the backlight is on for 15 seconds and then goes out. After more than 100PPM, the backlight is always on, and the LCD screen displays the real-time concentration value of the measured gas in the environment.

                     (2) When the measured gas concentration in the environment reaches the alarm setting value, the alarm will send out an audible and visual alarm indication, and the control output will be turned on after 10 seconds.

                     (3) The red indicator light indicates the alarm state. When an alarm occurs, the red indicator light flashes rapidly, and at the same time, the voice prompts - low limit alarm "please pay attention to carbon monoxide exceeding the standard, please keep ventilated" high limit alarm "please pay attention to the serious carbon monoxide exceeding the standard, please stay away from the dangerous area, woo Woo! Woo!" Until the CO concentration drops below the alarm set value, the alarm will be released, and the alarm information will be sent to the customer remotely when the alarm occurs.

                     (4) The yellow indicator light indicates the fault status. When the carbon monoxide sensor fails, the indicator light is always on, and the voice prompts "Please pay attention to the carbon monoxide sensor failure" and the LCD screen displays "Err", and the fault information is sent to the WeChat applet to notify the user.

                     (5) The yellow sensor service life limit indicator light, the sensor life time limit flashes, and the LCD screen displays "END". And send the fault information to the WeChat applet to notify the user.

                     (6) The battery low voltage prompt, the yellow fault indicator flashes once every 10 seconds, and the voice prompts "Please note that the battery power is too low, please replace the battery", and the fault information is sent to the WeChat applet to notify the user.

             2、Test the operation method of the mute button

                      Press the "TEST" button to test the product, the green indicator light is on, the red indicator light flashes 4 times, and a beep sound of "woo! Check whether the sensor, indicator, and display circuits are normal, and send the test results to the WeChat applet for display. Press it every 5 seconds, and the decibel meter is 1M away from the alarm. The sound pressure is greater than 85dB/ m. In the case of an alarm, press and hold the test button for 5 seconds to cancel the alarm voice prompt and output signal, and the alarm will not perform the detection function. After about 10 minutes, the detection and alarm function will resume. Press the test button before powering on. After 6 seconds of power on, the voice prompts that the Chinese and English have been switched successfully. The implementation standard is EN50291 in English voice state, and GB15322.2-2019 in Chinese voice state.。

  Safety Knowledge Of Carbon Monoxide And Gas

            1、Introduction To Carbon Monoxide And Gas

                      After carbon monoxide enters the human body, it will combine with hemoglobin in the blood. Because the binding capacity of carbon monoxide and hemoglobin is much stronger than that of oxygen and hemoglobin, the amount of hemoglobin that can be combined with oxygen is sharply reduced, which will cause the body tissue to appear hypoxia, resulting in the human body Death by suffocation. So carbon monoxide is toxic. Carbon monoxide is a colorless, odorless and tasteless gas, so it is easy to ignore and cause poisoning. It is often caused by the inhalation of gas or liquefied gas pipes produced by coal stoves, or inhalation of industrial gas and carbon monoxide in mines when the ventilation of the family room is poor.。

            2、Carbon monoxide poisoning phenomenon and harm

                       ● This product must be powered by the correct power supply. If it cannot be powered normally, the alarm will not work normally.

                      ● Mild: slight headache, weakness, chest tightness.

                      ● Severe: severe headache, nausea, and limb weakness.

                      ● Severe: headache, irritability, nausea, mental confusion, impaired vision, muscle weakness, dizziness.

                      ● Extremely severe: convulsions, unconsciousness, coma, collapse, death.

            3、Carbon monoxide safety precautions

                      Always open indoor doors and windows to keep indoor air circulation, install carbon monoxide alarms at appropriate locations, and monitor the concentration of carbon monoxide in real time. If the alarm alarms, remind people to leave the dangerous area to prevent carbon monoxide poisoning.

            4、Police Handling

                      When the concentration of carbon monoxide in the air environment exceeds the set concentration value of the alarm, the alarm will send out an alarm voice prompt and an indicator light alarm signal. At this time, the following measures should be taken: immediately close the valve channel, open the doors and windows to keep the indoor air circulating, and leave In dangerous areas, if the alarm continues to alarm, please notify relevant departments or professionals to deal with it. If the inspection is a false alarm, the user should check whether the installation location of the alarm is appropriate.。
