What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This is a wireless doorbell button that sends a radio signal to compatible Silent Call Signature Series receivers when pressed by a visitor. It's designed for people with hearing loss who rely on visual or tactile alerts (like flashing lights or bed shakers) instead of an audible chime — the transmitter pairs with a Sidekick II receiver that triggers those alerts. This is just the transmitter component, not a complete system; you need at least one Signature Series Sidekick II receiver to actually get any notification. It operates on the 418 MHz frequency, so it only works within the Silent Call Signature Series ecosystem — it won't pair with receivers from other brands or older Silent Call product lines.
