SMOKE ALARM
Ionization sensing alarms may detect invisible fire
particles (associated with fast flaming fires) sooner
than photoelectric alarms. Photoelectric sensing
alarms may detect visible fire particles (associated
with slow smoldering fires) sooner than ionization
alarms. Home fires develop in different ways and
are often unpredictable. For maximum protection,
Kidde recommends that both Ionization and
Photoelectric alarms be installed.
