What is the most common type of residential fire alarm?

The single-station smoke alarm is the most common type of residential fire alarm because it is designed to operate independently, providing immediate notification to occupants in the home whether they are near or far from the unit. This type of alarm is typically installed in various rooms throughout the residence, allowing for effective smoke detection and alerting users to potential fires.

Single-station smoke alarms are straightforward to install and maintain, which contributes to their prevalence in homes. They are also generally cost-effective, making them accessible for most homeowners.

In contrast, other types of alarms, such as multi-station smoke alarms, require interconnection with other alarms, which can complicate installation and require more extensive wiring. Photoelectric and ionization smoke alarms refer to the technology used to detect smoke, but single-station alarms utilize one type of technology or the other and are predominantly standalone, reinforcing their commonality for residential use.
