Serene Innovations Central Alert CA-CX with Doorbell

Summary

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

The Central Alert CA-CX is a notification hub for people who are deaf or hard of hearing that converts incoming calls, texts, and doorbell rings into bright flashing lights and loud audible alerts. It works with both landline and cell phones — a vibration sensor detects when your cell phone rings without needing any app or Bluetooth pairing — and a bed shaker jack lets you connect a shaker (sold separately) to be woken up by nighttime alerts. This is a fairly complete alerting solution out of the box: it includes the phone sensor unit, a doorbell transmitter, power adapter, and cables. One important limitation: the bed shaker is not included and must be purchased separately, so nighttime notification requires an additional purchase.

What Setup Looks Like

• Out of the box
  Plug landline phone cord into the CA-CX unit and wall jack, or place vibrating cell phone on the sensor pad — lights and loud ring activate automatically on incoming calls.
• With a guide
  
  1. Connect the doorbell transmitter near your front door following the included instructions — no wiring required.
  2. If using with a computer or tablet for Skype/video chat alerts, plug the included 2.5mm-to-3.5mm cable into the audio jack.
  3. Install 4 AA batteries (not included) for backup power in case of outage.
  4. Allow 20-30 minutes total for full setup of all components. See manufacturer support resources for detailed instructions.
