Kidde Combo Smoke and Carbon Monoxide Alarm:

Smoke and CO sensing technologies work together to detect real fires faster and reduce cooking-related nuisance alarms

Sealed-in lithium battery never needs replacing

Advanced photoelectric sensor may detect visible particles (associated with smoldering fires) sooner than ionization alarms

Alarm automatically activates when attached to the mounting bracket

Rapidly flashing LED alerts user if the alarm has sounded since the last time the test/reset button was used

Test/hush button tests alarm circuitry and activates hush features

Smart Hush temporarily silences nuisance alarms for approximately 10 minutes

Red LED will blink in conjunction with the alarm sound

End of life warning alarm chirps every 30 seconds to indicate the unit is in need of replacement

End of life indication can be silenced three days at a time up to 30 days to allow for alarm replacement at a more convenient time
