What Are the Different Types of Smoke Alarms That First Alert Makes?

Dual Sensor Photo Ion

• The Dual sensor photo ion alarm is designed with smart sensing technology. It is designed to alert you in the two most hazardous fires; smoldering fires and fast burning fires, while still reducing the number of false alarms from non-threatening situations. The dual sensor photo ion alarm also comes with an easy access battery door, allowing you to change the batteries without actually having to pull the alarm off of the wall.

Smoke/CO2 Combination Alarms

• Combination alarms detect both smoke and carbon monoxide. First Alert manufactures them as battery operated as well as hardwired units. The battery operated units feature the easy battery change drawer. The hardwired units are installed directly into your wall. Since they don't require batteries, they are easy to maintain. Both alarms contain a photoelectric sensor that reduces the number of false alarms from non-threatening smoke.

Photoelectric Alarms

• Photoelectric alarms have the ability to detect slow burning fires. These types of fires actually are the most likely to create smoke inhalation issues. This is different than the smoke that occurs when you burn something while cooking, which commonly causes false triggers for smoke alarms. Photoelectric alarms are able to detect the difference in the type of smoke, determining whether they actually are dangerous.

Ionization Alarms

• Ionization alarms are designed for detecting fast flaming fires. These alarms feature a mute button, in the event that the alarm is set off by non-threatening smoke or shower steam. They can be purchased in battery operated or hardwired models.

ONELINK alarms

• ONELINK alarms link all of the alarms in your home together. If one alarm detects a fire, all of the alarms will sound, ensuring that, no matter what size your home is, everyone will know that they need to exit the home. These types of alarms also are ideal for large buildings or apartments. They can be found as battery operated and hardwired units. First Alert also manufactures a ONELINK model that is voice activated. The voice programming option allows you to voice record specific dangers, like fire or carbon monixide. If a danger is detected, the alarm will use the voice recording to signify the type of danger present.
