What is the difference between an ionization smoke alarm and photoelectric smoke alarm?
Smoke alarms utilizing ionization technology generally activate faster in fast-flaming fires. Smoke alarms utilizing photoelectric detection technology generally activate fast in smoldering fires. While a properly installed and maintained alarm of either technology provides a critical baseline of protection, the Springfield Fire Department strongly recommends the installation of at least one smoke alarm of each type or the installation of dual-sensor alarms, which utilize both technologies.
