What to know before buying

Listing details to confirm

Listing details are inconsistent about power: the feature text says each transmitter uses a CR2032 battery and claims up to 4.5 years of use, while the details say batteries are neither included nor required. Confirm the transmitter power arrangement and whether batteries are supplied before buying. The 400m/1300ft range and 0–120 dB volume are manufacturer claims, not guaranteed results in a particular building.

Frequently asked questions

How many buttons and receivers are listed?

The feature description specifies two push buttons and four receivers. The product details list receiver and transmitter without quantities, so check the selected listing if the exact bundle matters.

Can the doorbell alert without sound?

The listing describes Sound Only, Light Only, and Sound + Light modes. Light-only mode is intended to provide a visual alert without a chime.

Does the transmitter need a battery?

The listing conflicts on this point. One feature claim says each transmitter uses a CR2032 battery, while product details say batteries are not required and none are included. Confirm the power arrangement before purchase.

Is the advertised 400 m range assured indoors?

No. 400m/1300ft is the manufacturer's claimed range. Walls and building layout may affect reception, so it should not be treated as a guaranteed indoor distance.
