What is an important feature to include when installing a garage door opener for safety?

Including a wall switch at least 60 inches above the floor is an essential safety feature when installing a garage door opener. This height ensures that the switch is out of reach of small children, reducing the risk of them accidentally activating the garage door opener. Additionally, placing the switch at this height allows for convenient access by adults while still maintaining a safety margin.

The other options may have their own advantages, but they do not prioritize safety in the same way. A manual switch just above the floor could pose a safety hazard for children, while a doorbell installed near the opener does not provide control for operating the garage door and offers no protection against unintended access. A motion sensor at the door could enhance convenience or additional safety, but it is not a standard requirement for the safe operation of a garage door opener. Thus, having a wall switch positioned appropriately addresses both operational convenience and safety protocols effectively.
