Signature Series Wireless Doorbell 418 MHz Transmitter (DB4-SS)

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.

What Setup Looks Like

• Out of the box
  
  1. Install the included 12-volt battery into the transmitter.
  2. Mount the unit beside your door using the two included screws.
• With a guide
  
  1. Verify your existing Signature Series Sidekick II receiver is powered and in range.
  2. Press the doorbell button to confirm the receiver triggers correctly — troubleshoot placement if signal doesn't reach receiver (typical range is 100–300 feet open air). See manufacturer support resources for detailed instructions.
