Questions & Answers

Does this alarm announce the name of the area or space where a fire is located

Some WiFi enabled alarms have the ability to announce the name of the room or space in which it is located. Does this alarm have this capability?
Asked by: Rittersdad
Ours do not. It does announce if it's fire or CO that's detected, though.

Asked by: cloe
They are warrantied for 10 years... The batteries 3-AA don't 10 years. Although some fire alarms do have Li-Ion battery that last ten years.
