Place your Google Nest Protect on the ceiling to monitor both smoke and carbon monoxide levels. If you have additional questions on where to install your alarm, follow the guidance of fire and local authorities.
Generally, you’ll need to replace your current smoke and carbon monoxide alarm when installing Nest Protect. However, you should be aware that existing alarms may not be installed in the right place. Make sure that you have the right number of alarms and correct placement in your home even if you already have alarms installed.
Rooms in your home that need a Nest Protect
The diagrams below show where Nest Protect should be installed. In addition to these guidelines, state and local jurisdictions may have their own requirements for alarm type, placement, and installation. Consult your local building codes and fire authorities to determine additional requirements that may apply in your location.
- Mark where the screws will go using Protect’s backplate as a guide.
- Installation on the ceiling is recommended.
- If you’re installing on the wall, make sure Protect is within 12 inches (30.5 cm), but not closer than 4 inches (10cm) to the ceiling.
- If the slope of your ceiling is more than 19 degrees, there’s a triangle of dead air below the peak that should be avoided. To check where the dead air ends, think of the peak of your ceiling as the top point of the triangle. The side of the triangle is your wall. The base of the triangle connects the wall to the slope of your ceiling. When the base is 90 cm (35.4 in) long, you get the outline of the dead air. Your smoke alarm should be installed on the ceiling or wall not more than 20 cm (7.9 in) below the dead air.
