Serene Central Alert Home/Cell Phone Sensor-Transmitter

Summary

AI-generated from vendor-published content · April 26, 2026

This device monitors both a landline phone jack and a resting cellphone, then flashes visual alerts whenever a call or text comes in — so someone who can't hear a ringing phone doesn't miss it. It's designed for people with hearing loss who rely on visual cues instead of audio signals, whether at home or in a room away from their phone. The unit works on its own as a standalone visual alerter, but it also integrates into the larger Serene Central Alert CA360 ecosystem, which can coordinate alerts for doorbells and door knocks across a home. One important thing to know: the cellphone alert works by detecting the phone's screen light or vibration in the cradle rather than via Bluetooth, so detection reliability can vary depending on your specific phone's behavior.

What Setup Looks Like

• Out of the box
  Plug the unit into a landline wall jack to begin detecting incoming landline calls and flashing visual alerts.
• With a guide
  
  1. Place your cellphone in the front cradle and adjust the cradle sensor so it reliably detects incoming calls and texts.
  2. Use the controls to set preferred flash patterns and adjust ring-tone volume to your needs.
  3. If integrating with the CA360 system, pair this transmitter with the base receiver following the pairing steps in the manual — allow 15–30 minutes. See manufacturer support resources for detailed instructions.
