Quick Answer
Smoke detectors should not be installed in unheated or uninsulated garages, as these areas may not be able to support the operating temperature range of smoke detectors. However, if you have a heated or insulated garage, you can install a smoke detector in this area, but it's essential to follow specific guidelines.
Choosing the Right Smoke Detector for a Garage
When selecting a smoke detector for a garage, look for one that is specifically designed for these types of environments. These detectors usually have a higher operating temperature range, typically between -22°F and 122°F (-30°C and 50°C). Some popular options include smoke detectors with a “garage” or “unheated space” rating, such as the Kidde i4618 or the First Alert BRK 3120B. These detectors can withstand the temperature fluctuations found in unheated or uninsulated garages.
Installing a Smoke Detector in a Garage
When installing a smoke detector in a garage, follow the manufacturer’s instructions and local building codes. Typically, the detector should be installed at least 3-4 feet off the floor, away from windows, and not within 3 feet of any fuel-burning appliance or heat source. It’s also essential to test the detector monthly and replace the battery annually. In addition, make sure the garage door is always closed when the garage is not in use to prevent the garage from becoming a chimney for the house.
