First alert dual sensor ionization photoelectric smoke detector.

The first alert smoke and fire alarm comes equipped with two different sensors to provide an early warning. First alert smoke detectors utilize differing technologies to achieve the very best result in offering steadfast protection. This hardwired alarm with battery backup gets rave reviews for its performance and fewer false alarms than similar products. Equipped with a dual photoelectric and ionization smoke sensor to quickly detect both fast burning and smoldering fires first alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958 based on a first alert brand trust survey in february 2018.

The first alert smoke alarm comes equipped with two different sensors to provide early warning. The first alert hardwire dual photoelectric and ionization sensor smoke alarm with battery backup is designed to provide peace of mind. First alert brk hardwire dual sensor smoke alarm review 1. Ionization smoke alarms are best for detecting rapid flame fires while photoelectric smoke alarms protect against slower smoldering fires.

Other popular technologies for smoke detectors are ionization alarms and dual sensor smoke detectors. Choosing between photoelectric ionization and dual sensing smoke alarms the first alert store understands the significance of selecting the appropriate first alert smoke alarm to safeguard families from the many dangers associated with the presence of smoke and fire. Ionization technology smoke detectors are generally more sensitive than photoelectric technology smoke detectors at sensing small particles which tend to be produced in greater amounts by hot flaming fires that are consuming combustible materials rapidly. The ionization sensor detects flaming fires such as grease fires or wastebasket fires and the photoelectric sensor detects smoldering fires such as when a lit cigarette ignites clothing or upholstery.

This alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning regardless of the type of fire. Smoke particles of varying sizes and number are produced in all fires. First alert battery operated dual sensor photoelectric and ionization smoke detector alarm 29 09 box 29 09 box. While all smoke alarms are designed to detect smoke different sensing technologies react differently to certain types of fires.

The ionization sensor is more sensitive to detecting flaming fires and the photoelectric sensor is more sensitive to detecting smoldering fires. The first alert brk 3120b smoke alarm is arguably the best dual photoelectric and ionization smoke alarm on the market.
