Wireless Doorbell Set HX Action: Wireless doorbell set with acoustic and visual call signaling (flashing light). It expands the existing doorbell system without wiring. The transmitter is placed directly next to the existing doorbell. When the doorbell is activated, the acoustic signal is converted by the sound-active sensor into a radio signal and sent to the receiver. Wireless Range Extender HX: By linking multiple HX wireless range extenders, you can achieve an unlimited range for the HX wireless doorbell sets/HX receivers.
