Good to know

The Bell-202.3 TXA is a transmitter only; a compatible Bell-200 series receiver is required to produce the chime. Multiple transmitters can be paired with one receiver, and one transmitter can trigger multiple receivers. Mounting screws and wall plugs are included. For best range, avoid mounting on metal surfaces or near large electrical appliances. The LED flashes with each press, confirming that the signal has been sent.
