Serene Innovations Central Alert CA360 CA-CX Cell Home Phone Sensor

Summary

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

The CA-CX is a phone alert sensor that converts incoming calls and text messages — from both cell phones and landlines — into visible flashing lights and an extra-loud audible ringer. It works by detecting the vibration from a cell phone placed on the unit, then triggering a bright flash and/or loud tone in the room; different green flash patterns distinguish landline calls from cell calls so you know which device is ringing. It's designed for people who are deaf or hard of hearing and might miss a ringing phone, especially when wearing hearing aids, in a noisy environment, or in another room. This is a complete unit that works on its own for daytime alerting, but a bed shaker accessory (sold separately) is needed for overnight notification, and expanding coverage to other rooms requires additional CA360 receivers sold separately.

What Setup Looks Like

• Out of the box
  
  1. Plug the unit into AC power and insert 4 AA batteries for backup.
  2. For landline alerting: plug your landline phone cord into the unit's phone jack.
  3. For cell phone alerting: set your phone to vibrate mode and place it on the sensor pad — flashing and ringing will activate when a call or text arrives.
• With a guide
  
  1. Adjust the vibration sensitivity switch to reduce false alarms based on your phone model and placement.
  2. Review the manual to customize ringtone selection and flash pattern preferences — allow 15–30 minutes. See manufacturer support resources for detailed instructions.
