The following article we’ll examine the importance to have smoke alarms as well as carbon monoxide detectors installed in your home, the various kinds available, and the reasons why professional installation and maintenance is vital.

Smoke Alarms

Smoke alarms detect smoke and then emit a loud alarm to alert you to the possibility of a fire. They work by using either the ionization process or photoelectric techniques to sense smoke molecules floating in the air. Ionization smoke alarms have a higher sensitivity to flaming fires, whereas photoelectric smoke alarms are better at detection of smoldering flames. It is suggested that homes have both kinds of smoke alarms installed to provide maximum protection.

There are two types of smoke alarms available including hardwired and battery-operated. Smoke alarms that operate with batteries are easy to install and maintain, however they need regular replacement of batteries. Hardwired smoke alarms however they are wired to the electrical system in your home and have a battery backup in case of power failures. They need professional installation but are more durable in the long run.

Smoke alarms should be tested every month at a minimum to be replaced after 10 years. It is important to put smoke alarms in every bedroom, outside each sleeping area and on every floor of your home, including the basement.

Carbon Monoxide Detectors

Carbon monoxide (CO) is a colorless, odorless gas that is produced due to the incomplete combustion of fuels such as propane, natural gas and wood. CO can be deadly when it is present in large quantities, which makes it vital to install a carbon monoxide detector in your home.

Carbon monoxide detectors work by sensing the level of CO in the air, and then emitting an alarm when CO levels become dangerous. There are two main types of CO detectors available including battery-operated and plug-in. The plug-in type of detectors requires professional installations while battery-operated detectors are easy to set up and maintain.

CO detectors must be tested at least once per month and replaced after 7 to 5-7 years. It is important to install CO detectors in areas that are used for sleeping and on all levels of your home, including the basement.
