What is the final step in installing a smoke detector?

The final step in installing a smoke detector is to test it for operation. This step is crucial to ensure that the smoke detector is functioning properly before it is put to use. Testing the device helps confirm that it is receiving power and that its alarm system works effectively. It also allows the user to become familiar with the sound of the alarm, which is essential for safety and awareness in case of a fire.

After the other installation steps have been completed—such as mounting the detector securely on the wall, connecting it to the power source, and adjusting settings if applicable—testing is the definitive way to verify that everything has been set up correctly. This step is not just about ensuring that the device looks properly installed; it is about ensuring readiness for emergencies where every second counts.
