2-in-1 Combination Smoke & Carbon Monoxide Alarm with Voice Alerts (Battery Operated)



The Kidde combination Smoke & Carbon Monoxide alarms offer protection from two deadly threats in one unit. They come with a 10-year sealed battery that provides a variety of benefits to those who rely on continuous battery-operated smoke and carbon monoxide detection in their homes. The voice warning feature accompanies the alarm sound during an alarm event helping users to differentiate verbal announcements such as; “Replace Alarm” at end of alarm life, and “Hush mode activated” when a nuisance alarm is silenced. 


  • Wireless Interconnect – Proprietary radio signal joins multiple alarms together, so when one alarm sounds they all sound
  • Voice Notifications – Unit verbally announces “Fire!”, "Carbon Monoxide", and other alerts such as “Replace Alarm,” which helps the user better understand the current status of the unit
  • 10-Year Sealed-in Lithium Battery – No battery replacement required over the 10-year life of the alarm
  • Alarm Locate Feature – Quickly find initiating alarm by silencing other alarms in the network
  • Photoelectric Sensor – Smoke alarm contains an advanced photoelectric sensor that may detect visible particles (associated with smoldering fires) sooner than ionization alarms
  • Hush – Will temporarily silence nuisance alarms and will not allow hush mode to be activated unless the unit is in alarm mode
