The Kidde 20SD10-V adds crystal-clear voice alerts to the 10-year sealed battery DETECT platform, announcing "Fire!" so occupants know exactly what action to take. Enhanced photoelectric sensing reduces false alarms from cooking while delivering fast smoke detection. Self-testing ensures reliable operation at all times. The alarm sounds 3 long beeps with a red light flash and voice announcement when smoke is detected. No battery changes are ever needed — at end of 10-year life, the alarm notifies you to replace the unit.
What does the voice alert say on the 20SD10-V?
When smoke is detected, the 20SD10-V announces "Fire!" clearly alongside 3 long beeps and a red light flash. The voice alert helps occupants immediately understand the nature of the emergency so they can react quickly.
Does the 20SD10-V ever need a battery change?
No. The 20SD10-V has a 10-year sealed battery that cannot be replaced. At end of life, the alarm chirps to let you know it is time to replace the entire unit, eliminating surprise middle-of-the-night battery chirps.
How is the 20SD10-V different from the 20SD10?
The 20SD10-V is identical to the 20SD10 but adds voice alerts that announce "Fire!" when smoke is detected. If you have family members, especially children or elderly occupants, who would benefit from clear verbal emergency communication, the 20SD10-V is the better choice.
Does the 20SD10-V have interconnect capability?
No. The 20SD10-V is a standalone battery-powered alarm with no hardwired or wireless interconnect. For interconnected coverage with voice alerts, consider the hardwired 20SA10-V DETECT-line model.
What sensor does the 20SD10-V use?
Like all DETECT-line alarms, the 20SD10-V uses a photoelectric sensor with enhanced sensing technology to reduce false alarms from cooking while delivering fast, reliable smoke detection.
