As homeowner, the security of your family is a top priority. One way to protect them is to install smoke alarms and carbon monoxide detectors in your house.

The following article we’ll examine the necessity of having smoke alarms as well as carbon monoxide detectors in your home, as well as the many kinds of models available, and the reasons why having a professional install and maintain them is vital.

Smoke Alarms

Smoke alarms are devices that detect smoke and then emit an alarm sound to notify you to the possibility of a fire. They work by using either the ionization process or photoelectric technology to detect smoke particles floating in the air. Smoke alarms that are ionized have a higher sensitivity to flame fires, while photoelectric smoke alarms are more effective at detect smoldering fires. It’s recommended that homes are equipped with both types of smoke alarms in order to provide maximum protection.

There are two main 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, on the other hand they are wired to your home’s electrical system and have batteries in the event of power failures. They require professional installation but are more reliable in the long run.

Smoke alarms need to be tested at least every month as well as replaced once every 10 years. It is essential to install smoke alarms in each bedroom and outside every sleeping space and on every floor of your home, including the basement.

Carbon Monoxide Detectors

Carbon monoxide (CO) is an inert gas with no color and smell that is created by the incomplete combustion of various fuels, like propane, natural gas and wood. CO can be deadly when it is present in large quantities, which makes it essential to have a carbon monoxide detector in your home.

Carbon monoxide detectors operate by sensing the level of CO in the air, and then emitting an alarm when levels become dangerous. There are two kinds of CO detectors that are battery-operated and plug-in. Plug-in detectors require professional installation, while battery-operated detectors are easy to set up and maintain.

CO detectors should be checked at least once a month and replaced every 5-7 years. It is important to install CO detectors close to sleeping areas and on every level of your house, including the basement.

Combination Smoke Alarms and Carbon Monoxide Detectors

Smoke alarms that are combined with carbon monoxide detectors offer dual protection all in one. They work by using photoelectric and ionization sensors to detect CO and smoke levels. They also come with features like alarms for voice and digital displays that can provide more information in the case in the event of an emergency.

Professional Installation and Maintenance

While smoke alarms and carbon monoxide detectors are easy to install however, it is important to have a professional electrician do the job. They will ensure that devices have been placed correctly and at the proper places, thus reducing the chance of false alarms and missed detections. Professional electricians also carry out regular maintenance to ensure that the devices are operating well and to replace them when necessary.
