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

Setup with instructions The transmitter requires positioning or wiring near an existing alarm, wireless pairing with a separately purchased receiver unit, and testing to confirm correct operation. A family member with the manual could reasonably set this up in under 30 minutes, but it's not self-serve because it depends on another device and involves a non-obvious setup sequence.

What it is

Summary

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

This wireless transmitter listens for the sound of household smoke, CO, and gas alarms — including newer T3 and T4 alarm tones — and sends a radio signal to a compatible CentralAlert receiver unit, which can then flash lights or vibrate to get your attention. It's designed for people who are deaf or hard of hearing and may not reliably hear a standard audible alarm go off. This is not a standalone device — it requires a separate CentralAlert receiver (such as the CA-360 or CA-RX) to actually deliver the alert; without one, this transmitter does nothing visible or tactile on its own. Also this is a supplemental alerting aid, not a certified fire protection device, so it should be used alongside — not instead of — a compliant fire safety system.

What Setup Looks Like

  • Out of the box
    Install 2 AA batteries (not included) and press the test button to confirm communication with your CentralAlert receiver unit.
  • With a guide
    1. Position the CA-AX next to your existing smoke/CO alarm so its microphone can detect the alarm sound, or connect it directly to the alarm if a direct-connect option is available.
    2. Pair the transmitter with your CA-360 or CA-RX receiver following the pairing steps in the product manual — typically takes 10–20 minutes.
    3. Run a test with the alarm to confirm the receiver activates correctly. See manufacturer support resources for detailed instructions.
