Product Description

smoke and carbon monoxide detector

Smoke Detector Carbon Monoxide Detector Combo, 2 in 1 Smoke and Carbon Monoxide Detector

Smoke detector carbon monoxide detector combo has 2 in 1 protection, using high sensitivity photoelectric sensor to detect smoke and high stability electrochemical co sensor to detect carbon monoxide.

Once carbon monoxide or smoke reaches its alarm sensitivity level, both sound alarm and LED indication will be given out to warn you to take action to avoid it.

LCD screen of this smoke and carbon monoxide detector doesn't have a constant display, it shows blank in a standby mode. Or in order to preserve the battery there is no constant display, but it always keeps a standby mode. It will show number after batteries installed or when you press the test button, or when dangerous levels happen. Standby mode means no light on the screen, it will not disturb you when you need to sleep.

360-Degree Air Holes

This smoke detector carbon monoxide detector has 360-degree air holes, it means that smoke alarm detects smoke or carbon monoxide from all around, providing you with a safer surrounding.

LED Displays

  • Green LED: Test the smoke detector’s electronics by pressing the test button for several seconds, the fire alarm will give out sound.
  • If the smoke detector carbon monoxide detector combo chirp every 30 seconds with green LED out or Err is displaying on the LCD, that means the smoke and carbon monoxide detector is malfunction.
  • Red LED: Red LED will flash and the fire alarm beep at the same time. Red LED will flash during a CO alarm, a fire alarm and a low battery mode beep.
  • The smoke detector carbon monoxide detector combo will beep after battery installed, it means that the battery is installed properly.

Reset Instruction:

If the smoke and carbon monoxide detector beeps continuously after a smoke or carbon monoxide test, the beeping will not stop until the sensor's smoke or carbon monoxide concentration recovers. This is no need to reset.

If the smoke and carbon monoxide detector beeps continuously because of misinformation or fault, please try to reset.

When you receive our smoke alarm first time, after inserting batteries, sometimes it may keep beeping because we did a factory test before, so the battery was unplugged without the charge inside being drained. So you need to try to reset.

Reset Method:

1. Remove batteries, then press test button several times so that excess electricity will be discharged.

2. Press and hold the test button, at the same time, install batteries. Keep pressing and holding until led light flashes, then release your hand, this smoke and carbon monoxide detector recovers.

If reset still doesn't make it recover normal, please do not hesitate to find us, we will try our best to help you solve problems.

Precautions for Routine Maintenance of This Product:

1. In order for the smoke alarm to always maintain a normal working condition, this product requires regular maintenance.

2. Clean the smoke detector regularly every week with a soft bristle brush or hoover.

3. Because grease and dust can block smoke and carbon monoxide from entering the sensor, if this alarm is installed in a kitchen, garage, or hearth where there is a lot of grease and dust, install the product at an appropriate distance away from grease and dust.

4. We recommend that the batteries should be replaced regularly, usually every 3 months, to prevent the sensitivity of the product from being affected by low battery power.

5. In order to maximise the success of the smoke or carbon monoxide going into the smoke inlet, we strongly recommend mounting the alarm on the wall or ceiling, as these places will bounce the smoke or carbon monoxide into the side inlets contact sensors, ensuring that the product will be able to sense them faster and in a timely manner.

6. Warm Tips: This smoke and carbon monoxide detector has an alarm threshold, only when the concentration of smoke or carbon monoxide reaches the alarm threshold, the alarm will be alarmed. This alarm threshold is also to prevent false alarms.

One detector kept reading 999 co levels even outside. I tried new batteries and troubleshooting it, but nothing worked. I asked for a replacement To be sent however there’s still no date as to when it’s coming, just delayed, so now I’m stuck with a smoke detector that does not work until they decide to ship it.

We were able to get rid of our CO unit since these units act as a smoke alarm & CO. They are easy to install and like the digital readout.

These are 3x AAA battery powered optical smoke detectors, and the ad claims that they also detect CO (carbon monoxide - killing gas with no smell that is produced by pellet and wood-burning furnaces and fireplaces). So having CO detection capability is very useful in places with fire-based heating. It is less essential in the homes with gas or electric heating where CO may not happen.The construction is nice and sturdy, the alarm sound is a bit weaker than expected but OK. They are affordable on every budget and are better than nothing.On the "con" side: they are not UL-listed and thus will not pass home inspection. And they do not pass a rule that detector cannot be installed in place without battery.There is also no manual describing the principle of operation and how to test its CO sensitivity. There are four or more different technologies available, and each have different sensitivity and longevity. The manual does not tell the details and does not tell when the sensor must be replaced. Google for finding more information on CO detectors.The lack of UL-certification and no information about CO sensing and testing dropped one star.
