A reliable signal with clear, customizable alerts

Rely on a robust FM signal with one-to-one pairing to reduce cross-door interference in multi-door setups. In open space, expect a dependable range up to 1300 feet. The transmitter conserves energy when idle, while the receiver remains ready to deliver a crisp chime when needed.
