How it works

Place near each alarm

We plug each listener into an outlet within direct line of sight of the smoke detector so the microphone can reliably hear the alarm pattern.

Connect and configure

We connect each device to Wi-Fi through the app, link it to your account, and configure alert settings and notification contacts.

Test the full alert chain

We press the test button on your smoke alarm and confirm the listener detects it and sends a push notification to your phone in real time.

We can help

Problems we fix

Ambient noise from HVAC equipment or appliances interfering with the microphone
App notification permissions not enabled on iOS or Android blocking alerts
Multiple alarm brands in the home producing different tone patterns the listener must learn

Smart Smoke/CO Listener Setup — FAQ

Does this replace my smoke detectors?

No — listener devices work alongside your existing smoke and CO alarms, adding phone alerts to alarms you already have. Your original alarms still sound and function exactly as before.

Will it work with any smoke alarm brand?

Listeners detect the standard alarm pattern used by almost all residential smoke and CO detectors. We test it with your specific alarms during setup to confirm it recognizes the tone correctly.

What if I am not home when the alarm goes off?

The listener sends a push notification to your phone the moment it hears the alarm, wherever you are. You can also add family members or neighbors to receive the same alerts.

Is this a good alternative to replacing all my smoke detectors?

It is a cost-effective option when your existing alarms are still compliant and working but lack connectivity. If your alarms are old or out of compliance, replacing them with smart detectors is the better long-term move — a service we also offer.
