A smoke detector is a device that detects smoke, typically as an indicator of fire. Smoke detectors are usually installed in the ceiling or on a wall and are designed to sound an alarm when they detect smoke. Some smoke detectors also have a built-in strobe light to alert people with hearing impairments.
Smoke detectors are an important part of a home safety plan. They can help to alert people to a fire and give them time to escape. Smoke detectors should be installed in every home and should be tested regularly to ensure that they are working properly.
