You should not attempt to disable a smoke alarm unless you’ve already activated a replacement unit. To stop a hardwired smoke alarm from beeping, reset the device or silence the alarm. If you’re removing a hardwired alarm, shut off the power, turn the unit counterclockwise to remove it from the ceiling, and disconnect the wiring.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable. 

To stop a smoke alarm from chirping, you must first determine what the device is alerting you to. If your battery is out or has been removed, simply change the battery and the chirping should stop. If it does not, try resetting the alarm, checking the breaker, or calling a professional to take a look.

Pellet stoves are safer than wood stoves in many ways. They don’t produce as many creosote deposits as wood stoves do, they create less smoke, and the flames are contained, decreasing the risk of any sparks or embers creating a house fire. Pellet stoves also burn more cleanly and efficiently than wood stoves do.
