What app does the P4010ACS-WF use?
The P4010ACS-WF connects to the free Kidde app (iOS and Android). Setup is simple — scan the QR code on the back of the alarm to add it to the app. The app provides real-time notifications if smoke is detected, remote status checks, and Smart Hush to silence false alarms from your phone.
Does the P4010ACS-WF detect carbon monoxide?
No. The P4010ACS-WF is a smoke-only smart alarm. For CO detection, consider the P4010ACSCO-WF (smoke + CO), the P4010ACSCOAQ-WF (smoke + CO + indoor air quality), or install a separate Kidde CO alarm.
