The First Alert SC9120LBL hardwired smoke and carbon monoxide combination alarm with 10-year battery back-up features an ionization smoke sensing chamber and an electrochemical carbon monoxide sensor. The 10 year battery backup allows for continued monitoring, for the life of the alarm, even during power outages. Intelligent sensing technology is designed to reduce nuisance alarms and one button silences them if they do occur. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. An end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Two locking features prevent battery tampering, and installation and connection to AC power is easy with the "quick-connect" wiring harness. Connect it to compatible BRK or First Alert alarms within a single-family residence and when one alarm sounds they all will.

  • 10-Year battery backup means constant monitoring for the life of the alarm even during a power failure

  • Features an electrochemical CO sensor and ionization smoke sensor

  • Indicator lights display the presence of smoke or carbon monoxide; an 85-decibel siren provides loud warning upon detection

  • Single test/silence button

  • Adapter plugs included for simple installation when replacing other branded alarms

  • Smoke and CO alarms should be placed on every level and in every bedroom of the home

  • Tested to meet UL standards

  • 10-Year limited warranty
