Serene CentralAlert Home/Cell Phone Sensor-Transmitter

Summary

AI-generated from vendor-published content · June 8, 2026

This transmitter monitors both a landline phone jack and a cradle where you rest a mobile phone, 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 who are deaf or hard of hearing and need a visual or tactile substitute for auditory phone alerts. The unit works as a standalone alerting device but is also designed to integrate with Serene's CentralAlert CA360 system, triggering remote receivers (bed shakers, strobe lights) elsewhere in the home. It stores missed-call notification via flashing, so you'll know a call came in even if you were in another room. This is an add-on component — getting full whole-home alerting requires the CA360 base system and additional receivers, sold separately.

What Setup Looks Like

• Out of the box
  
  1. Plug the unit into a landline wall jack to begin detecting incoming calls on that line.
  2. Place your cell phone in the front cradle for call and text alerting — visual flash activates automatically.
• With a guide
  
  1. To integrate with the CentralAlert CA360 system, pair this transmitter with the base unit following the pairing instructions in the manual.
  2. Add optional remote receivers (bed shaker, strobe) to extend alerts throughout the home — allow 30–60 minutes for full setup. See manufacturer support resources for detailed instructions.
