Kinds of Carbon Monoxide Alarms and Alerts

Home security systems today will often come with carbon monoxide alarms as one of their security system parts. These devices are designed to protect you against this odorless, colorless, poisonous gas caused by the partial burning of fuel. A home security professional or local housing department representative can clue you in on the laws about carbon monoxide (CO) detectors in your area; many homes are required to have one. But even if it’s not required for you, it’s still a good idea to have at least one in your home. So here are some of the kinds of CO alarms and CO alerts you can purchase for an affordable price (they’re usually between $15-20 and $50 and they last 5 or so years).

CO Sensors

For starters, when the amount of CO in the air is a low concentration, the alarm may not sound for a long while. But when the amount of CO in the air is a high concentration, the alarm will alert you in a couple of minutes. This is because many things in our world can produce low levels of carbon monoxide, and so low concentrations do not necessarily imply there is an emergency or dangerous health risk.

Opto-chemical CO Sensors are like the original CO alerts that had a chemical pad that would change color when it mixed with carbon monoxide. Unfortunately, this does not give you a numerical level of CO, which is why these sensors provide only the lowest protection. They are also the most affordable.

Biomimetic CO Sensors use metal salts, a chromophore, and cyclodextrins, and the darkening effect in CO’s presence can be seen with an infrared LED light. The darker the color, the more carbon monoxide in the air.

Electrochemical CO Sensors are fuel cells that create an electrical current related to the carbon monoxide in the air; the current is able to detect the concentration of CO. These sensors are better than some other CO alarms because their measurement of CO concentration is accurate, they do not take much power, and they last a long time. As it is, they are the most common CO alerts in the states.

Semiconductor CO Sensors use a ceramic base with tin dioxide wires to sense the presence of CO. It requires a very high temperature to detect CO, and the monitoring integrated circuit checks the sensing element’s detection of CO. They have one of the longest life spans of CO alarms and are popular in some other countries like Japan.

Digital CO Alarms

Though a bit more expensive, these can tell you exactly what the level of carbon monoxide is in your home. Additionally, they keep a record of previous recordings so that you can observe when levels rose higher for any reason.

There are other kinds of carbon monoxide alarms, including portable and wireless alarms. Take advantage of the technology we have available to us today to detect poisons that the human senses cannot detect. You can call 866-565-4305 to learn more about carbon monoxide and CO alarms today.
