October 21, 2026 — A consumer has reported a serious incident involving a Google Nest Protect 06A battery-operated smoke and carbon monoxide alarm, where the device allegedly began beeping unexpectedly, emitted a burning electrical smell, and was found to have extremely hot batteries, posing a potential fire hazard. Fortunately, no injury or property damage occurred as the batteries were removed promptly.

Serial: 06AA01AC242309E7

Incident Overview
On September 27, 2026, an incident report detailed a malfunction with a Google Nest Protect 06A smoke and carbon monoxide alarm. The device, which was manufactured on June 27, 2023, and installed around January 24, 2024 (well within its expected 10-year service life), began emitting an unexpected beeping sound. Following the beeping, the user noticed a distinct burning or electrical smell originating from the alarm unit.
Upon inspection, the user removed the Nest Protect from its mounting location and opened the battery compartment. They discovered that one or more of the required batteries were extremely hot to the touch. Immediate action was taken to remove all batteries from the unit, discontinuing its use. The consumer noted that the batteries used were the specific type required by the manufacturer and printed on the device itself. There was no external heat source or other obvious reason for the batteries to become excessively hot. The consumer suspects an internal electrical fault, battery failure, or other malfunction within the Nest Protect as the cause of the overheating and burning odor. No injuries or property damage were reported, as the user intervened before the situation escalated further. The affected Nest Protect and batteries have been retained, and photographic evidence has been collected.
Safety Concerns
The reported incident with the Google Nest Protect 06A highlights significant safety concerns:
- Immediate Fire Hazard: An electrical fault or battery malfunction leading to extreme heat and a burning smell within a smoke and carbon monoxide alarm presents a clear and immediate risk of fire. While smoke alarms are designed to detect fires, an internal defect causing one to *start* a fire negates its primary safety function and creates a dangerous paradox.
- Carbon Monoxide Detection Failure: Should the device fail due to an electrical issue, it could also compromise its ability to detect dangerous levels of carbon monoxide, silently accumulating and posing a severe health risk to occupants.
- Property Damage Potential: Uncontrolled overheating can lead to ignition of surrounding materials, causing significant structural damage to homes or businesses.
- Risk to Occupants: Overheating devices could injure individuals through burns if touched, or more severely, endanger lives if a fire starts, especially if it occurs while occupants are sleeping or if the alarm itself fails to sound due to the malfunction. Vulnerable populations such as children, the elderly, or those with mobility impairments may have less time to react to a sudden fire.
- False Sense of Security: Consumers rely on smoke and CO alarms for critical life safety. A malfunctioning unit, particularly one that overheats or fails internally, undermines this trust and leaves households unprotected while giving a false sense of security.
What Consumers Should Do
If you own a Google Nest Protect 06A or similar smart home safety device, we recommend the following:
- Check Your Device: Verify the model number and manufacture date of your Google Nest Protect. The affected unit in this report was manufactured June 27, 2023, and installed January 24, 2024.
- Be Alert for Warning Signs: Pay attention to any unexpected beeping (not related to low battery alerts), unusual odors (burning, electrical), or signs of discoloration or heat from your device.
- Discontinue Use if Malfunction Occurs: If your Google Nest Protect exhibits any signs of overheating, emits strange smells, or behaves unusually, immediately and carefully remove it from its mounting.
- Handle Batteries with Caution: If you suspect overheating, approach the unit cautiously. If batteries feel hot, use protective gloves or a non-conductive tool to remove them. Dispose of hot or damaged batteries properly, following local regulations for hazardous waste. Do not puncture or expose them to open flames.
- Do Not Attempt Repairs: Do not try to repair a malfunctioning unit yourself. This could exacerbate the problem or void any warranties.
- Retain the Product and Evidence: If your device experiences a similar incident, do not discard it. Retain the unit, the affected batteries, and any photographic or video evidence. This information is crucial for investigations.
- Report the Incident: File a detailed report with the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. This helps safety authorities identify patterns and initiate necessary actions like recalls.
- Contact the Manufacturer: Reach out to Google Nest customer support to report the issue and inquire about their recommendations or potential replacements.
