Dual Sensing Smoke Alarms: All of the Strengths/None of the Limitations

First Alert Dual Sensing Smoke Alarms ensure maximum coverage by utilizing photoelectric and ionization technologies. The individual installation of photoelectric and ionization smoke detectors offers a limited range of defense in securing your surroundings from the many dangers associated with undetected smoke. Here are the primary strengths attributed to both types of smoke detectors:

  • Photoelectric smoke alarms specialize in detecting fires that are indicative of their slow smoldering properties. These fires are defined by their propensity to produce large smoke particles that can smolder for hours before bursting into larger flames (ie. those caused by cigarettes or candles burning on couches or bedding).
  • Ionization smoke alarms are designed to identify fires that are defined by their rapid flaming qualities. These fires are characterized by their ability to generate and combust at an advanced speed (ie. kitchen grease fires or fires fueled by paper burning in a wastebasket).

Due to the overspecialization of each technology, it's becoming increasingly important to outfit homes with a smoke detector that's capable of implementing both photoelectric and ionization capabilities. The First Alert Store has outfitted its online selection with a group of First Alert Dual Sensing Smoke Alarms that offers all of the strengths and none of the limitations.

Selecting the Correct First Alert Dual Sensing Smoke Alarm:


The benefits of implementing a dual sensing smoke detector in the home setting should be obvious. Standalone ionization and photoelectric smoke alarms limit your defensive options by searching for only one type of smoke pattern. Due to the unpredictable properties associated with each fire, single detection smoke alarms can be seen as a liability. First Alert Dual Sensing Detectors effectively operate as two alarms by fusing both ionization and photoelectric technologies. The First Alert Store offers three dual sensing smoke alarms that feature strengths individual to each detector:

There's really no wrong selection as each of these First Alert Dual Sensing Detectors has the capacity to notify homes to the presence of both types of fire origins.

Where Do I Install My First Alert Dual Sensing Detectors?


This is a good question as certain areas in the household can be more susceptible to a potential fire. The National Fire Protection Association (NFPA) has compiled a set of guidelines that will allow homeowners to get the most from each unit's installation.

  • One on every level of your home (including finished attics and basements)
  • Inside every bedroom
  • In hallways adjoining any sleeping area
  • At the top of the first-to-second floor stairway
  • The bottom of the basement stairway

Following this set of installation rules and regularly performing weekly tests on your alarm's functionality will ensure additional levels in peace of mind. When it comes to protecting your family and home from the potentially disastrous results of smoke and fire exposure, you simply cannot afford to take any risks. Protect What Matters Most with the installation of First Alert Dual Sensing Smoke Alarms.

The First Alert Store has made it easy to outfit your home as they've included an extended selection of smoke alarms, carbon monoxide alarms and combination alarms.
