What happens here

The installer unboxes a new white wired doorbell button. He explains that wired doorbells have two screw terminals for connecting wires. Typically, one red and one white wire are used, and it doesn't matter which wire goes to which terminal as the system operates on low-voltage direct current (DC) or alternating current (AC) where polarity is often not critical for basic doorbell functionality. He then connects the exposed wires from the wall to the two terminals on the back of the new doorbell button, tightening the screws to ensure a secure connection.

Goal: Securely connect the low-voltage wires to the new doorbell button.

Tools and materials

  • New Doorbell Button — The replacement doorbell unit
  • Phillips Head Screwdriver — To tighten the terminal screws on the new doorbell
