Features: The electrochemical carbon monoxide alarm detector is dedicated to the detection of carbon monoxide. Carbon monoxide is a toxic gas that is colorless, odorless, non-irritating, and incapable of using facial features. It is mostly caused by the burning environment of fireplaces, wood, coal, electric heaters and water heaters with insufficient air. Therefore, in order to protect the safety of home life, it is recommended to install a carbon monoxide alarm detector in the kitchen, bathroom, living room, bedroom and garage where the air is not circulating for a long time. Powered by a DC1.5V AA battery. When the alarm detector alarms, an ≥70dB alarm sounds and the red alarm light flashes. The green indicator flashes once every 30 seconds during normal operation. The detector has a low voltage alarm function and test function. Press the test button on the panel for a few seconds to sound an alarm and the red indicator flashes. The detector uses low-power technology. In theory, the battery is replaced once a year.。 Carbon monoxide alarm point: 100×10-6 (the LCD starts to display the concentration when 30×10-6); The effective range of CO: 0×10-6-500×10-6; Sensor: Electrochemistry. Power: 1.5V*3 AA alkaline battery(Not included) Working current: quiescent current is less than 50uA, The alarm current is less than 50mA. Working temperature: -10oC~+55oC. Gas interface humidity: 10% -90%. Buzzer sound level: more than 70 decibels at 1 meter. Battery life: about 1 year. Low voltage alarm: 3.3V (green light flashes, beeps and displays LO momentarily); Green light: normal monitoring Red light: alarm Yellow light:: fault Sensor fault detection function: The yellow LED flashes and the buzzer (the fault elimination can be recovered). （）Installation: This product can be placed directly on the appropriate tabletop (note that the height is not less than 1 meter) or installed on the wall. If it is installed on the wall, select a suitable installation area, draw two holes on the ceiling or wall according to the hole of the mounting bracket, drill two holes in the two holes, and insert two plastics into the two holes expansion screw. Then fasten the back of the mounting plate against the wall, insert and tighten the mounting screws until the mounting bracket is securely removed. This detector is a closed type device and is not allowed to open. Please insert the battery into the battery compartment of this unit. Return the back of the detector to the installed position and make sure the installation card is installed. （）Work, test: Work：After the detector is installed, it needs to wait for 60 seconds to enter the working state. In the working state, the preparatory light on it is flashing green light about every 30 seconds. When the carbon monoxide gas is detected to be higher than 30×10-6, the detector liquid crystal screen begins to display the current gas concentration; when the concentration is higher than 100×10-6, the crystal screen displays the current gas concentration while the buzzer and the red indicator light flash. When the concentration of carbon monoxide is greater than 500×10-6, the liquid crystal display shows –HH; when the air recovers to below 50×10-6, the detector turns to the normal monitoring state. Test: Press and hold the test button during normal operation, the detector will emit a crisp and loud pulsation alarm and a red alarm signal (it is recommended to do a test once a week to ensure the normal operation of the detector). Avoid installing in the following locations: 1、Too close to the door, windows, fans and other places will affect the sensitivity of the alarm, because these places generally have a faster air circulation. 2、Can not be installed in high humidity places, such as the bathroom, the top floor or the temperature is higher than 50ºC or below 10ºC. Easy maintenance: Every six months, you need to clean the alarm once to keep the work efficiency. First remove the battery, then use a soft brush to sweep the dust, then install the battery. If you find the following problem: 1、press the test but no sound 2、gas test but no sound 3、the reserve light is no longer stable flashing Try the following to improve: 1、Check if the power supply is working properly. 2、Simply clean it. 3、Ask the electrician to check thoroughly If the above measures still can't improve the situation, please do not try to repair. If the alarm is still under the maintenance period, please return it to the company together with the proof of purchase date (invoice). Installation and maintenance precautions: ●It can't be installed in places with high temperature and high wind speed, otherwise it will affect the sensitivity; ●In order to keep the sensor working well, clean the sensor every 6 months. First remove the battery, then use a soft brush to sweep the dust, then install the battery. Package Included: 1 x Carbon Monoxide Alarm 1 set of fitting screws 1 x white box
