Should a fire destroy the power cabling (or an electrical malfunction causes a short circuit and burning cables) you won't hear anything.
Most of todays fires not caused by arson are mainly caused by electric malfunctions / overheating. To rely on main power for a fire alarm (smoke or CO) doesn't appeal to me.

Good point locally most of fires are caused by lighting during the summer and from fireplaces & Christmas trees during winter. My electrical power coming into the house is buried in the ground but it is not uncommon to lose power during an ice storm. With me I think my biggest exposure would be forgetting to change the batteries.
