First Alert Dual Sensor Ionization Photoelectric Smoke Detector

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.

First alert dual sensor ionization photoelectric smoke detector.

The first alert brk 3120b smoke alarm is arguably the best dual photoelectric and ionization smoke alarm on the market. First alert brk hardwire dual sensor smoke alarm review 1. This hardwired alarm with battery backup gets rave reviews for its performance and fewer false alarms than similar products. First alert battery operated dual sensor photoelectric and ionization smoke detector alarm 29 09 box 29 09 box.

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. Dual sensor technology is the preferred choice of fire service professionals for its ability to detect both flaming and smoldering fires. The ionization sensor is more sensitive to detecting flaming fires and the photoelectric sensor is more sensitive to detecting smoldering fires. The dual sensor smoke detector has both ionization and photoelectric technology inside.

Smoke particles of varying sizes and number are produced in all fires. While all smoke alarms are designed to detect smoke different sensing technologies react differently to certain types of fires. The photoelectric and ionization sensors on this fire detector alert you to both smoldering and fast flaming fires offering comprehensive detection and early warning. 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 first alert smoke and fire alarm comes equipped with two different sensors to provide an early warning. This alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning regardless of the type of fire. First alert smoke detectors utilize differing technologies to achieve the very best result in offering steadfast protection. Ionization smoke alarms are best for detecting rapid flame fires while photoelectric smoke alarms protect against slower smoldering fires.

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. Other popular technologies for smoke detectors are ionization alarms and dual sensor smoke detectors.
