How it Works

Carbon monoxide alarm is convenient and easy to install and operate. This device has an advanced level of protection that uses a battery to work. It has a digital display that is easy to read even in low light angles. It shows the level of carbon monoxide it senses in the air. There are two LED colors that you will see here. There’s a green LED that flashes every 30 seconds which indicate that the device is working correctly. The green LED also flashes before it reads the carbon monoxide in the air and when you press any button on the device. The other one is the red LED that will alarm loudly when a dangerous level of carbon monoxide is present in the air. The alarm has a pattern of 4 short beeps followed by 5 seconds of silence and followed by four short beeps with red LED flashes correspondingly. The cycle will continue for 4 minutes until the device resets or the gas eliminated

  32. V***y

    Growth accounted for 20 days. Buy for 265r (if the price is higher, wait 2-3 days) Work from 3 finger batteries. The kit does not include batteries. Sensor works on carbon monoxide, smoke, etc. Natural gas will not work!!! Do not put it in the oven or as I in Pan smoke membrane is very sensitive and can damage the sensor. Although I dough stuck. All works. The sensor preprogrammed alarm under certain concentrations within a certain time. Such as exceeding 300 within 3 minutes-triggered alarm siren. Exceeding 100 within 20 minutes-triggered alarm siren. In other words, sensor no fool, works with strong concentrations faster, with weak longer.
