August 20, 2026 – Residents in Dunns Corners, Rhode Island, are experiencing persistent nuisance alarms from their Kidde P4010DCS-W interconnected wireless smoke and carbon monoxide detectors, with eight units installed in June 2025 allegedly going off frequently in multiple condo units. Despite reports from a local Fire Marshall that these models are defective and no longer sold, manufacturer Kidde has not issued a recall, prompting consumer frustration over product reliability.
Product Details
Incident Overview
An owner of a condo unit in Dunns Corners, Rhode Island, reported an ongoing issue with eight interconnected wireless Kidde P4010DCS-W smoke alarm/carbon monoxide detectors. These units were installed in June 2025 by the prior owner and were reportedly required by the state of Rhode Island as the only approved models at that time.
According to the report, the alarms have been consistently triggering nuisance alarms in two of the three condo units where they are installed. The complainant was informed by the Dunns Corners RI Fire Marshall that these specific models are no longer sold because they are considered defective. Despite this, Kidde has not issued a recall for the product.
The consumers are now facing the dilemma of having to pay out-of-pocket to replace these alarms, which are only one year old and were advertised with 10-year batteries. They are seeking a recall from the manufacturer, hoping that a refund would allow them and potentially “thousands of people” in similar situations to purchase new, safe, and working alarms.
Safety Concerns
The persistent malfunction of smoke and CO detectors, even if manifesting as nuisance alarms, presents several significant safety concerns:
- Nuisance Alarm Fatigue: Frequent false alarms can desensitize residents to the sound of an alarm. This “alarm fatigue” might lead individuals to ignore or dismiss a genuine emergency (such as an actual fire or carbon monoxide leak) when it occurs, delaying critical response times and potentially leading to injury, death, or extensive property damage.
- False Sense of Security: If consumers believe their alarms are inherently faulty or unreliable, they might lose trust in the safety system. This could lead to residents disabling alarms, neglecting their maintenance, or failing to replace them, leaving their homes dangerously unprotected against real threats.
- Financial Burden on Consumers: Consumers are forced to prematurely replace relatively new and often expensive safety devices that were advertised with a long battery life (10 years in this case). This unexpected cost places an unfair financial burden on homeowners who invested in what they believed were reliable, state-compliant safety systems.
- Regulatory Compliance Ambiguity: The statement from the local Fire Marshall indicating the product is “defective” and “no longer sold” raises serious questions about the product’s suitability for its intended safety purpose, irrespective of past compliance with older UL standards. This could create confusion regarding current safety requirements and approved devices.
- Potential for Undetected Hazards: While the incident specifically mentions nuisance alarms, the underlying issue could potentially compromise the alarm’s ability to detect actual fire or CO threats. A system prone to false positives might also be prone to false negatives, meaning it fails to alarm when a real danger is present.
- Impact on Multi-Unit Dwellings: In interconnected systems within multi-unit buildings like condos, a defect in one alarm can affect others, causing widespread disruption and anxiety for many residents.
What Consumers Should Do
If you own Kidde P4010DCS-W smoke alarm/CO detectors or similar models and are experiencing persistent nuisance alarms, here are the steps you should consider:
- Do Not Ignore Alarms: Treat every alarm activation as a genuine emergency until you have definitively determined the cause. If a fire or CO source is suspected, evacuate the premises immediately and contact emergency services.
- Check Your Model Number: Locate your alarm units and verify if you own the Kidde P4010DCS-W model. The model number is usually printed on the back or side of the alarm.
- Perform Regular Maintenance: As advised by the manufacturer, regularly clean your smoke/CO alarms according to the user manual. Use a soft brush or vacuum attachment to remove dust and debris from the sensing chamber. Ensure alarms are placed away from sources of humidity, steam (e.g., bathrooms, kitchens), vents, and fans as instructed in the manual.
- Contact the Manufacturer: If you are experiencing persistent nuisance alarms despite proper maintenance and placement, contact Kidde directly. They have offered to replace units that are not meeting expectations. Refer to the contact information provided below.
- Report Incidents to the CPSC: File a report with the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report contributes to a larger database that helps the CPSC identify patterns, investigate potential hazards, and initiate recalls or safety campaigns.
- Consider Replacement: If nuisance alarms continue to be a significant issue, causing distress or creating a potential safety hazard (due to alarm fatigue), consider replacing the units with newer models that comply with the latest safety standards, despite the financial cost. Prioritize the safety of your home and family.
Manufacturer’s Response
UTC Fire & Security, on behalf of Kidde, provided a response on August 11, 2026. Kidde asserted their commitment to residential fire safety, stating that all their products comply with the rigorous standards set by Underwriters Laboratories (UL) for performance and reliability.
Kidde acknowledged that nuisance alarms can occur but stated they are rare and often have causes unrelated to product defects or safety. They emphasized their long history of selling millions of units to satisfied customers. The manufacturer suggested that the primary causes of false alarms are typically improper maintenance, such as dust and debris in the sensing chamber, or incorrect placement away from vents and fans, despite customer claims of thorough cleaning.
Kidde maintained that their data indicates the P4010DCS-W product is safe and operates as intended, fully compliant with UL 217, specifically the sixth edition. They clarified that the product is no longer manufactured because it was designed to the UL 217 sixth edition, which has since been superseded by the 10th edition. Kidde stressed that the evolution of safety standards does not imply that previous models were defective.
Kidde has offered to replace any alarms that are not meeting customer expectations free of charge, potentially with a different model that might be a better fit for the customer’s specific use. They stated they would reach out to the customer directly for further assistance.
