Co Alarm low-level co alarm levels as low as 5 ppm and is battery powered to provide protection during power outages. It also has a digital display that updates every 15 seconds to let you know if the CO concentration has changed. This alarm is ideal for those who are particularly sensitive to low levels of CO such as infants, children, elderly, and people with respiratory or heart conditions. It also offers early warning to help avoid long-term exposure which can cause illness or even death.

Most carbon monoxide detectors sold in stores and home centers are UL Listed (UL 2034) but they typically don’t alarm until the CO concentration is above 70 PPM. That’s too late and doesn’t give occupants enough time to ventilate or evacuate the area.

Low-level CO exposure can also cause flu-like symptoms including fatigue, shortness of breath and memory loss. It can also aggravate existing medical conditions such as asthma or heart disease.

The low level co alarm will warn you of chronic low-level CO exposure that may not trigger symptoms such as headaches, dizziness or chest pain. It also gives an early warning of possible problems like a blocked chimney or faulty exhaust system which might lead to higher levels of CO in the future.

These units use the same electrochemical sensor and electronics as standard CO detectors but they have special software algorithms that detect low-level CO exposure. They are also more expensive because they are made in smaller quantities than the mass-produced detectors. To test your new alarm, consult your user guide for exact instructions but generally speaking you push the Peak Level button until it’s silenced (4 quick beeps) and then press the Test/Reset button to reset the unit to its initial state.
