Placement

The U.S. Fire Administration recommends alarms in bedrooms, outside sleeping areas and on every home level, including the basement.

It recommends interconnected alarms, so an alert from one sounds throughout the system. Manufacturer instructions govern the appropriate ceiling or high-wall position.

Hardwired installation belongs with a qualified electrician.

Maintenance

Check how each alarm is powered before deciding what needs replacement. USFA advises monthly tests.

Its guidance distinguishes replaceable batteries from sealed, long-life units; a sealed battery is not an invitation to open the device. Follow the manufacturer’s replacement instructions and check the manufacture date.

The agency says alarms need replacement ten years after manufacture.

Keep protection working

Do not remove a battery to silence an alarm triggered during cooking. USFA warns that disabling an alarm can be deadly.

For alarm-type requirements, contact the local fire marshal. Ask the fire department through its nonemergency number about any available assistance; this guide does not establish a particular local program.
