Kidde AC/DC Hardwired Combination Smoke/CO Voice Alarm
Kidde AC/DC Hardwired Combination Smoke/CO Voice Alarm
Item # P4010ACSCO-W

The P4010ACSCO-W is an AC/DC powered smoke and carbon monoxide alarm with 10-year battery backup that features supervised wire-free interconnect capability and provides enhanced intelligibility for users. The voice warning feature accompanies the 85dB tone during an alarm event and helps reduce confusion with verbal announcements such as “Replace alarm” at end of alarm life, and “Hush mode activated” when a nuisance alarm is silenced. The three-color LED ring helps users quickly determine standby, alarm, or error mode of the alarm. Users are further shielded from late night battery chirps by the unit’s Ambient Light Sensing feature, which establishes a day/night cycle and prevents alarm chirping in dark conditions.
