What Plug In Carbon Monoxide Detector To Buy?

Carbon monoxide or CO is an odorless and colorless gas. It can be fatal since there is no way to detect it. Often called the ‘silent killer’ because it is undetectable, the gas is produced due to incomplete combustion. Gas stoves, wood burning stoves, gas clothes dryers, oil furnaces and other such appliances are capable of releasing the gas if they don’t work properly or if they aren’t ventilated properly. If the malfunction is not looked into, carbon monoxide can keep accumulate until it is at deadly levels in your home. When exposed to the gas, you experience symptoms such as dizziness, nausea, headache, vomiting, upset stomach, confusion and chest pain. This, of course, is if you are awake. If you are asleep especially after drinking alcohol, you have a much higher chance of dying from exposure to the gas.

This is where a plug in carbon monoxide detector comes in. The usefulness of a carbon monoxide and gas detector can be determined by the fact that not only is it strongly recommended by the Centers for Disease Control and Prevention or CDC, but it is also a legal requirement in many areas and many types of buildings. However, it isn’t just enough to install one and then forget about it. The detectors don’t last forever and even the best smoke and carbon monoxide detector will give up the ghost at some point. You will need to replace it when it does.

What Should You Look for in a Carbon Monoxide Smoke Detector?

A carbon monoxide detector is an absolute essential in your house. However, there are features you must consider before you decide which plug in carbon monoxide detector or battery operated detector is the best one for you.

Loud Alarm

The Underwriter’s Laboratory or UL certifies plug in carbon monoxide detectors and the ones it recommends have a minimum 85 decibel alarm that can be heard at least ten feet away. After all, you do need to hear the alarm if something goes wrong. There are accommodations made for those who suffer from hearing loss whether because of age or because of any other reasons. Check out carbon monoxide detector reviews to determine what works best for you.

Digital Display

A digital display can let you know at a glance the status of your plug in carbon monoxide detector. You will be able to see the current levels of CO in the room, the peak levels over a period of time, battery power and other such information. However, find out whether the detector you have selected is a low level carbon monoxide detector or not. You don’t want to be caught unprepared because your detector can only sense high levels of CO. Go through carbon monoxide detector reviews to find out.

Testing Functionality

Make sure that your plug in carbon monoxide detector can be tested every month. Whether a high or low level carbon monoxide detector, most devices come with a testing function. There is generally a button you can use to activate the test which will let you know if your plug in carbon monoxide detector has sensors that are working or need to be replaced.

Additional Detector Features

 Sensor Alarm

Nothing lasts forever – not even the best smoke and carbon monoxide detector. The sensors on a carbon monoxide and gas detector will stop working after a period of five to seven years. The older models of the plug in carbon monoxide detector did not come equipped with any way to let you know when the sensors were done and needed to be replaced. That is not the case anymore. The newest carbon monoxide detector, whether a plug in or a battery operated one comes equipped with an end of life timer. When the sensors are finished, the timer will begin beeping to let you know that the sensors need to be replaced. However, it is best if you don’t wait for the timer to tell you when to replace the sensors. Instead, conduct a check once a month to ensure that the sensors are still working.

If the device does start chirping to indicate a dead sensor, don’t remove the battery or unplug it to silence the noise. You may think that you’ll remember to replace the sensors but we all can be forgetful sometimes and it would not do to be forgetful on this point. Replace low batteries if it is a battery powered detector or replace the sensors if they’ve stopped working.

Stand Alone or Interconnected

A plug in carbon monoxide detector comes in two types – stand alone and interconnected. As the name suggests, stand alone carbon monoxide detectors that plug in or are battery operated are not connected to any other alarm system in the house. They operate on their own. The plug in versions can be used with an AC socket with a battery backup in case the power goes out. They are the easiest to install. If they detect CO in the house, they will sound the alarm but will not trigger any other alarms such as the smoke detector. This can be a major disadvantage if the CO detector that is triggered is in a room far away from where you are, and you cannot hear the alarm.

An interconnected carbon monoxide detector connects with other alarms to form a network of alarm systems in your house. It can be a plug in carbon monoxide detector or one that is battery operated. It is generally connected up to a network that includes smoke detectors as well. The clear advantage of such a system is that when one alarm sounds, it triggers all the other alarms. This means that you will know of the danger regardless of which room you’re in.

It is absolutely essential for your safety and the safety of your family that you install a plug in carbon monoxide detector. Regardless of whether you have any devices in your home that emit the gas or not, you should install the detectors. You never know when the neighbor’s malfunctioning wood bartbeque smoker or your car accidentally left on could allow the gas to seep into your house.
