Smoke & Carbon Monoxide Detectors Buying Guide

Smoke and carbon monoxide detectors warn you of the presence of smoke or carbon monoxide in your home. Both smoke and carbon monoxide are killers. So, the advance-warning that smoke and carbon monoxide alarms provide you with could save lives. To help you choose the best smoke and carbon monoxide detector for your home, here is a brief smoke and CO detector buying guide.

Check the Regulations in Your Area

Some areas have regulations with regards to home smoke and carbon monoxide alarms. You will need to meet those local requirements if you want to sell your home. Local regulations may stipulate the type of detectors you will need and where in the home you will need to install them.

Types Of Smoke and Carbon Monoxide Alarms

The alarms listed above are combined smoke and carbon monoxide detectors. Carbon monoxide detectors warn you if there is a dangerous level CO gas in the home. Smoke alarms will give you early warning if a fire has broken out your home. There are two types of smoke detectors. Photoelectric smoke detectors are best for detecting smoldering fires. Ionization smoke detectors are best for detecting the smoke from fast-burning fires. Because the two types of smoke alarms detect different types of fires, it is recommended that you have a mixture of the two types of smoke detectors installed in your home.

Power Source

Smoke alarms and CO alarms can be either mains-powered or battery-powered. Battery-powered carbon monoxide and smoke detectors are easier to install, but you will need to change the batteries. Some smoke and CO alarms have batteries that last the lifetime of the alarm.

Interconnected Smoke and Carbon Monoxide Alarms

Some smoke and CO alarms can be interconnected. This means that if one alarm is triggered, all the alarms in the home will sound. Interconnected alarms are the safest option, but if you live in a small apartment, they may not be necessary.

Smart Smoke and CO Detectors

Smart fire alarms and carbon monoxide detectors are very convenient, but they are more expensive. A smart alarm will connect to an app on your phone. So, you will be able to silence the alarm from your phone, and you will get alerts when the batteries need changing. The other big benefit of smart detectors is that you will get an alert of danger even when you are not at home.

Where You Need Smoke and Carbon Monoxide Alarms

You should have smoke and CO alarms in every bedroom of the home and on every level of the property. You should also have alarms in high-risk areas, such as the laundry room, the attic, workshop areas, and the kitchen. As already mentioned, you should have a mixture of photoelectric and ionization smoke detectors. Interconnected fire alarm systems are the best smoke and carbon monoxide detectors to have in the home.
