The Kidde 20SA10-V combines hardwired interconnect, a 10-year sealed battery backup, and crystal-clear voice alerts into a single DETECT-line smoke alarm. Voice alerts announce "Fire!" alongside 3 long beeps and red light flash so occupants immediately understand the emergency. Enhanced photoelectric sensing reduces cooking false alarms. Self-testing ensures continuous readiness. Tested to UL 217 10th Edition. No battery changes ever needed for the backup battery.
What does the voice alert say on the 20SA10-V?
When the 20SA10-V detects smoke, it announces "Fire!" clearly alongside the standard 3 long beeps and red LED flash pattern. Crystal-clear voice alerts help occupants immediately understand the emergency and take the right action.
Does the 20SA10-V battery backup ever need replacement?
No. The 10-year sealed lithium backup battery cannot be replaced and lasts the life of the alarm. This eliminates surprise late-night battery chirps for the duration of the alarm service life.
How does hardwired interconnect work on the 20SA10-V?
The 20SA10-V connects to other Kidde hardwired alarms via the standard three-wire interconnect circuit. When any connected alarm detects smoke, all alarms on the circuit sound simultaneously. Up to 24 compatible devices (18 initiating) can be connected.
Why choose the 20SA10-V over the 20SA10?
Choose the 20SA10-V if you want clear verbal emergency communication. Voice alerts are especially valuable for households with children, elderly occupants, or anyone who may be confused by beeping tones alone. Both models have identical hardware otherwise.
What UL standard does the 20SA10-V meet?
The 20SA10-V is tested to UL 217 10th Edition, the current (2024) standard that includes stricter nuisance alarm resistance requirements compared to earlier editions.
