First Alert Optical Smoke Alarm

Essential Aspects of First Alert Optical Smoke Alarm

Smoke alarms are essential safety devices in homes, businesses and other buildings, providing an early warning of hazardous smoke conditions. Fire Safety experts recommend that every home be equipped with a smoke alarm on every level, including the basement and attic. First Alert is a leading manufacturer of smoke alarms, and their optical smoke alarms are among the most popular on the market.

First Alert optical smoke alarms use a photoelectric sensor to detect smoke. Photoelectric sensors are more sensitive to smoldering fires than ionization sensors, which are more common in older smoke alarms. They work by shining a beam of light across the sensor chamber. When smoke particles enter the chamber, they scatter the light and cause the sensor to trigger the alarm. Optical smoke alarms are less likely to be triggered by false alarms, such as cooking smoke or steam, than ionization smoke alarms.

First Alert optical smoke alarms are available in a variety of models, with features such as:

  • Battery-operated or hard-wired
  • 10-year sealed battery
  • Tamper-resistant lock
  • Escape light
  • Interconnected
  • Voice alarm

First Alert optical smoke alarms are easy to install and maintain. They come with all the necessary hardware and instructions. First Alert also offers a 10-year limited warranty on their optical smoke alarms.

If you are looking for a reliable and effective smoke alarm, First Alert optical smoke alarms are a great option. They are sensitive to smoldering fires, less likely to be triggered by false alarms, and easy to install and maintain.
