Step 1 Enter Your ZIP Code
The fire or carbon monoxide (CO) safety laws and legislation can be different depending on the city or state where the smoke or carbon monoxide alarms are being installed. Therefore, your zip code will help to provide the most accurate results for the safety products that will comply with your local legislation.*
Step 2 Select Smoke or Carbon Monoxide Alarm
Please select the hazard you are trying to protect against in your home. If you are trying to protect against smoke/fire, please select 'Smoke Alarm' and the results shown will be smoke alarms and smoke/CO alarms. If you are trying to protect against carbon monoxide (CO), please select 'CO Alarm' and the results shown will be CO alarms and smoke/CO alarms. Note: for combination smoke/CO alarms, only those combination alarms are displayed that meet both the smoke and CO laws in your area.
Step 3 Choose Hardwire or Battery Operated
Smoke alarms are powered by a battery or by your home's electrical system. If the smoke alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year sealed lithium battery. Alarms that receive their power from your home's electrical system (hardwired alarms) usually have a back-up battery, but the primary source of these alarms is hardwire AC power.
Step 3 Choose Hardwire, Plug-in or Battery
Carbon monoxide (CO) alarms are powered by a battery or by your home's electrical system. If the CO alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year sealed lithium battery. CO Alarms that receive their power from your home's electrical wiring system (hardwired alarms) usually have a back-up battery, but the primary source of these alarms is hardwire AC power. CO alarms that can be plugged into a standard power outlet, are called 'Plug-in' alarms, and these usually have a back-up battery, but the primary source of these alarms is AC power from the standard AC electrical outlet.
