The following article we’ll discuss the importance of having smoke alarms and carbon monoxide detectors in your home, the different types available, and the reasons why having a professional install and maintain them is vital.

Smoke Alarms

Smoke alarms detect smoke and emit an alarm that sounds loud to warn you to the possibility of a fire. They work by using either ionization or photoelectric technologies to identify smoke particles in the air. Ionization smoke alarms tend to be more sensitive flaming fires, whereas photoelectric smoke alarms are more effective in detection of smoldering flames. It’s recommended that homes have both kinds of smoke alarms installed to ensure maximum security.

There are two primary types of smoke alarms on the market that are battery-operated and hardwired. Smoke alarms that operate with batteries are easy to install and maintain, however, they require frequent battery replacements. Hardwired smoke alarms, however are connected to your home’s electrical system and are equipped with an emergency battery backup in case of power outages. They need professional installation but are more efficient in the long term.

Smoke alarms must be checked every month at a minimum as well as replaced once every 10 years. It is important to put smoke alarms in all bedrooms and outside every sleeping space and on every floor of your home, which includes the basement.

Carbon Monoxide Detectors

Carbon monoxide (CO) is an odorless, colorless gas that is generated through the incomplete combustion of fuels like propane, natural gas and wood. CO can be fatal in high concentrations, making it essential to have the carbon monoxide detector inside your home.

Carbon monoxide detectors work by sensing the level of CO present in the air and emitting an alarm when levels become unsafe. There are two kinds of CO detectors that are available: plug-in and battery-operated. The plug-in type of detectors requires professional installations while battery-operated detectors are easy to install and maintain.

CO detectors must be checked at least once each month, and then replaced every 5 to 7 years. It is essential to put CO detectors near sleeping areas and on all levels of your house, including the basement.

Combination Smoke Alarms and Carbon Monoxide Alarms and Detectors

Smoke alarms that are combined with carbon monoxide detectors combine protection all in one. They utilize both photoelectric and ionization sensors to detect CO and smoke levels. They also include features such as voice alerts as well as digital displays that provide more details in the event that there is an incident.
