Smoke Alarms and Carbon Monoxide Detectors: A Must-Have Inclusion for All Home

Posted by Local Electrician Western Sydney on 11 Dec 2025

As a homeowner, the safety of your family is an absolute priority. One way to protect them is by installing CO detectors as well as smoke alarms in your house. They can notify you in the event of a fire or a carbon monoxide leak, giving your family members and you time to evacuate and seek help. In this article, we will discuss the importance to have smoke alarms and carbon monoxide detectors installed in your home, the different types available, and the reasons why having a professional install and maintain them is essential.

Smoke Alarms

Smoke alarms detect smoke and emit a loud alarm to alert the user of the possibility of fire. They work by using either ionization or photoelectric techniques to sense smoke molecules in the air. Ionization smoke alarms tend to be more sensitive burning fires, while photoelectric alarms are better at detect smoldering fires. It’s recommended that homes are equipped with both types of smoke alarms to provide maximum protection.

There are two types of smoke alarms on the market: battery-operated and hardwired. Battery-operated smoke alarms are easy to install and maintain, however, they require frequent battery replacements. Smoke alarms that are wired, in contrast, are connected to your home’s electrical system and have an emergency battery backup in case there are power outages. They require professional installation , but are more reliable in the long run.

Smoke alarms should be tested every month at a minimum and replaced every 10 years. It’s important to place smoke alarms in every bedroom, outside each sleeping area and on each level of your house, including the basement.

Carbon Monoxide Detectors

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

Carbon monoxide detectors work by sensing the level of CO present in the air, and then emitting an alarm when CO levels become unsafe. There are two kinds of CO detectors that are battery-operated and plug-in. For plug-in detectors, professional assistance is required for installation and battery-operated detectors are simple to set up and maintain.

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

Combination Smoke Alarms and Carbon Monoxide Alarms and Detectors

Combination smoke alarms and carbon monoxide detectors provide dual protection all in one. They work by using photoelectric and ionization sensors to detect smoke and CO levels. They also come with features like alarms for voice and digital displays that provide more information in the event that there is an incident.

Professional Installation and Maintenance

While smoke alarms and carbon monoxide detectors can be simple to install but it’s essential to have a professional electrician perform the task. They can ensure that the devices are set up properly and in the correct places, thus reducing the chance of false alarms or missed detections. Professional electricians also carry out regular maintenance to ensure the devices are operating correctly and can replace them if required.

DIY maintenance and installation can lead to potential risks like improper placement or faulty wiring, which can result in false alarms or, worse, a failure to detect CO leaks or fires.
