The First Alert Combination Smoke and Carbon Monoxide Alarm is the perfect device for anyone who wants to keep their family safe. The dual sensors detect smoke or carbon monoxide, which are both dangerous substances that can cause accidents in homes where there’s not a lot of ventilation, like apartments with fireplaces or even small children running around on the floor while they cook dinner. With an easy-to-set alarm system (you just plug it into your outlet), this will make sure you’re always notified when something goes wrong! I think one of these should be installed by every major appliance so people don’t live life without knowing what could happen at any moment.
Additionally, the CO sensor detects carbon monoxide leaks from multiple sources – for example, faulty fuel-burning appliances and generators running inside or too close to homes. The loud 85-decibel siren will alert you to the threat while the unique alarm sounds on its face distinguish a smoke warning versus a CO leak warning.
This smoke and carbon mono oxide alarm are battery-operated, so you don’t need an electrician for installation. Requiring just two AA batteries and featuring an easy-access battery compartment for quick changes, this unit has a single button that allows you to silence a false alarm or test the unit in case of an emergency.

How to Replace a 9V Battery
- So, firstly use a plastic tab to open the battery lid gently.
- Now take the old batteries out.
- Look at the battery to identify the (+) and (-) contacts. While installing the battery in your alarm, ensure that they match the same polarity in the battery drawer. Note: the negative side has a larger opening in the back of the battery drawer, so it will get fit one way without forcing it closed.
- Insert the fresh battery into the compartment with the positive (circular ◯ ) contact closest to the middle of the detector. The negative (hexagonal ⬢ ) contact needs to be closer to the outer of the detector.
- Now is the time to close the battery compartment. If it won’t close, it is possible that the battery is inserted in the wrong direction.
