Wire-Free Interconnected Battery Powered Combination Smoke & Carbon Monoxide Alarm

P4010DCSCO-W

The P4010DCSCO-W is a 10-year, sealed battery smoke and carbon monoxide (CO) alarm 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.

  • Voice Notifications

  • Bug Screen: Protects alarm from insect ingression
