Understanding Wireless Garage Door Keypad Systems
A wireless garage door keypad allows homeowners to open the garage door by entering a code that sends a radio signal to the garage door opener receiver.
Key points about how these systems operate include:
- The keypad acts as a transmitter, sending a coded signal to the opener when the correct digits are entered.
- The opener receiver verifies the signal before activating the garage door system.
- Rolling code technology changes the signal after each use to reduce the risk of unauthorized access.
- Battery power allows the keypad to operate independently from the opener wiring.
- Signal strength and mounting position can influence how reliably the keypad communicates with the opener.
Wireless keypads function as part of the automatic opener system, which is why the International Code Council emphasizes that garage door openers and related access devices must comply with safety provisions in residential building codes.
