Regularly Change CO and Smoke Detector Batteries


Any home that uses natural gas to power its appliances, from the heating system to the stove and range in the kitchen, must have carbon monoxide detectors installed strategically in different rooms. And all homes, regardless of what type of energy they use, need to have smoke detectors to alert the family in case a fire starts. It’s common today for most detectors to have both smoke detection and carbon detection abilities. If you don’t have proper detectors in place or need help finding the right places to have them installed, an electrician in Chicagoland can help you. Our electricians are experts at hardwiring smoke and CO detectors into homes to provide the best defense in case of carbon monoxide leaks and fires.

You Must Regularly Check the Unit Batteries

It’s not enough to have CO and smoke detectors professionally hardwired into your home’s electrical system. We strongly recommend you test the batteries for the units every six months. It’s a good idea to make this testing part of the maintenance you have done for your HVAC system in the spring and fall. This makes it easier to remember.

“But my detectors are wired into the home’s electrical system. Why worry about batteries?” This is a comment we hear a lot. Freestanding units obviously must operate from batteries, so it seems strange to worry about batteries if the detectors are connected directly into a power supply.

However, these hardwired detectors also have batteries in them as backups. Power losses to homes have become more frequent over the last decade, especially during periods of storms and extreme cold. (This last winter was an excellent example.) You don’t want your detectors to shut off in cases of a power outage—you need them then more than ever! Press the “test” button on each detector, and if you get a long beep in response, the batteries are still in good shape. Change the batteries if you don’t get a response.

When the Smoke/CO Detector Regularly Beeps

If you begin to hear a detector in your house emit a sharp beep every few minutes (or more frequently), this is the unit warning you its battery needs to be replaced. Don’t let the beeping go on or try to silence it by dismantling the detector! That warning beep exists for a good reason: you always want backup systems working.
