First Alert SMCO100V-AC | Smoke & CO Alarm with Voice Alerts

When seconds count, the First Alert SMCO100V-AC (Catalog #1046778) doesn't just beep — it tells you what's wrong and where. Voice Location Alerts announce both the type of danger (smoke or CO) and the preprogrammed room location of the triggered unit, so you always know exactly where to respond.

Voice Location Technology

Program up to 11 room locations (bedroom, kitchen, basement, etc.). When triggered, the alarm announces e.g. "Warning — smoke detected in the basement." This clarity is especially valuable in multi-story homes and for hearing-impaired household members.

Dual-Sensor Protection

  • Photoelectric smoke sensor — superior detection of slow, smoldering fires
  • Electrochemical CO sensor — accurate carbon monoxide detection

Key Features

  • Voice location alerts — announces danger type and room
  • Hardwired with AA battery backup (included)
  • Easy Adapter Plug for standard wiring boxes
  • Interconnectable for whole-home coverage
  • 85 dB alarm
  • 10-Year Limited Warranty
