Kidde CO Detector Plug-In Wall 4-Pack with 9V Battery Backup & Digital Display

Smart, reliable CO monitoring for every level

The Kidde Carbon Monoxide Detector is a plug‑in wall unit designed for easy, everyday use with a clear digital readout. With a built‑in 9‑volt battery backup, it stays on guard even when power isn’t available. This 4‑pack lets you place detectors on every story and near sleeping areas, giving you a consistent, simple way to stay aware of CO levels in your home.

Real‑time visibility matters. The digital LED display updates the detected CO level every 15 seconds, so you can quickly gauge changes and respond if needed. When CO is detected, the unit emits a loud 85‑decibel alarm to help you notice an issue even from another room. The Peak Level Memory remembers the last time CO was detected or the unit was tested, making it easier to review history at a glance.

Two built‑in tools designed for real life use

• Easy Installation – simply plug into a standard 120V outlet in your home.
• 9‑volt Battery Backup – protection during power outages to keep monitoring active.
• Digital LED Display – shows CO level and updates every 15 seconds for quick readings.
• 85‑decibel Alarm – a clear, audible alert when CO is detected.
• Peak Level Memory – records the last detection or test time for quick review.
• Smart‑Hush Button – silences the alarm for about 8 minutes during routine activities like cooking.

Placement matters for best results. An extension cord is included to help you position detectors on tables or shelves, while a compact wall‑plug design blends into most rooms. The detectors are UL certified and come with a 10‑year limited warranty, reflecting Kidde’s commitment to long‑term home safety. They meet key standards including UL 2034 and NFPA guidance, and align with state and housing program requirements, helping you distribute coverage across different living spaces.

For best results, install a carbon monoxide detector on every level and near bedrooms. The 4‑pack format makes it easy to plan placement across living rooms, hallways, and sleeping zones, supporting a practical approach to home monitoring. While a CO detector cannot guarantee prevention, it can provide timely alerts and peace of mind by offering clear information and audible warning when it’s most needed.
