What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This battery-powered microphone transmitter listens for sounds in a room — a baby crying, a timer going off, a doorbell, or an alarm — and wirelessly sends a signal to a compatible Silent Call Signature Series receiver, which then alerts the user through flashing lights or vibration. It's designed for people who are deaf or hard of hearing and can't rely on hearing ambient sounds around the home. The transmitter itself is just one piece of a larger alerting system — you'll need at least one Silent Call Signature Series 418 MHz receiver (sold separately) to actually get the alert. Before buying, note that this only works within the Silent Call Signature Series ecosystem, so it won't pair with receivers from other brands or older Silent Call product lines.
