Smoke Alarms: Why and How?

The Facts...

  • 3 out of every 5 home fire deaths resulted from fires occurring in homes with no smoke alarms or non-working smoke alarms.

  • 46% of homes that had smoke alarms but they did not operate was caused from missing or dead batteries.


  • Smoke alarms should be placed on every level of the home, in every sleeping area, and inside of every bedroom.

  • Smoke alarms should be placed away from vents and out of corners to avoid dust and dead air space.

  • If the ceiling is not fit for direct placement of smoke alarms, place alarm 6-12 inches down the wall.

  • It is best to interconnect smoke alarms meaning, when one sounds; they all sound. 

  • Install at least 10 feet from a cooking appliance to minimize nuisance alarms.

  • Never paint smoke alarms.


  •  The NFPA recommends checking your smoke alarms weekly. Please check your smoke alarms at least once a month to maintain proper operation.

  • As of 2018, sealed 10-year Lithium-Ion battery smoke alarms are required in the home to achieve more reliable smoke alarm coverage in dwellings.

  • Replace your entire smoke alarm system ten years after the manufacturers date printed on smoke alarm. 

Two Types

There are two types of smoke alarms: photoelectric and ionization.

  • Photoelectric smoke alarms generally respond more to smoldering fires.

  • Ionization smoke alarms respond more to flaming fires.

  • For the best protection dual-sensor smoke alarms are recommended. These smoke alarms have both photoelectric and ionization sensors.

The new 10-Year Lithium-Ion Battery Smoke Alarms provide better coverage in case of a home fire. In Maryland, legislation has now been passed that as of January 2018 all 9-volt battery operated smoke alarms must be replaced with the 10-year Lithium-Ion battery Smoke Alarms. The operation of these new smoke alarms are in hopes to reduce home fire deaths throughout the state and they are more appealing than your average 9-volt smoke alarms.

  • More affordable overall, only purchase the smoke alarm. No need to purchase 9-volt batteries every six months.

  • Batteries are tamper-proof and cannot be removed. Allows for greater chance of response during a fire. 

  • Still checked once a month for maintenance.

  • Entire system replaced 10 years from manufacturers date printed on smoke alarm.

  • Hush Button feature to reduce nuisance alarms.
