Price is what the vendor listed when last checked. Confirm it with the vendor before buying.

Setup with instructions This is a complete alert system in one box, but it takes a bit of hands-on setup. You connect a landline, place a cell phone on the sensor, and pair the doorbell. A family member can do this in about 30 minutes using the instructions. A professional isn't needed, but it isn't open-the-box-and-go either.

What it is

Summary

AI-generated from vendor-published content · October 1, 2026

The CA-CX is a central alert unit that turns phone calls, text messages and doorbell rings into a loud ringer and a bright flashing light. It works with a landline phone, a cell phone set to vibrate, and Skype or FaceTime calls. Each source has its own flash pattern and adjustable ring tone, so you can tell a landline call from a cell call without looking at the phone. It also picks up Wireless Emergency Alerts when your cell service sends them, and you can plug in a bed shaker (sold separately) to get alerts while you sleep. A doorbell sensor, phone cord, and a short audio cable come in the box. The unit runs on wall power with a battery backup, but the 4 AA batteries are not included.

What setup looks like

  • With a guide
    1. Plug the unit into the included AC adapter. Plug your landline phone into it with the phone cord, or set your cell phone to vibrate and rest it on the phone sensor.
    2. Place the doorbell sensor near your door, and choose the ring tones you want for each source.
    3. If a phone isn't being detected, connect it to the unit with the included audio cable. Add 4 AA batteries for backup, and a bed shaker if you want one. Expect about 30 minutes in total.
