December 10, 2025 – A recent incident involving a multi-unit apartment complex has brought to light the serious dangers posed by counterfeit smoke alarms.

Product Details
Incident Overview
On November 22, 2025, the Worcester Fire Department responded to reports of a fire alarm activation at a local multi-unit apartment complex. During their investigation, firefighters made a critical discovery: counterfeit smoke alarms had been installed throughout the entire building. A resident informed authorities that the landlord had recently replaced all the smoke alarms.
Upon inspection, the devices, branded as Siterwell Electronics Co., Limited GS517, displayed several alarming characteristics indicative of fraudulent manufacturing. These included numerous spelling mistakes on the device itself, the appearance of a fake UL listing logo, and the phrase “UL 217” without any clear indication that the product actually complies with or is certified to that safety standard. The devices also stated “Made in China.” The presence of these counterfeit alarms within a residential building presents a grave and immediate safety risk to all occupants.
Safety Concerns
The installation of counterfeit smoke alarms like the Siterwell GS517 poses severe and potentially life-threatening risks:
- Immediate Dangers: The primary function of a smoke alarm is to provide an early warning in the event of a fire. Counterfeit devices are not manufactured to safety standards, meaning they may fail to detect smoke or fire altogether, or they may do so with significant delays, leaving residents with critically little time to evacuate. This could lead to fatalities or severe injuries.
- False Sense of Security: Residents living with counterfeit smoke alarms are under a dangerous illusion of safety. Believing they are protected, they may not take additional precautions, increasing their vulnerability in an actual fire emergency.
- Unreliable Performance and Malfunction: Substandard components and poor manufacturing quality inherent in counterfeit products can lead to unreliable performance, including frequent false alarms or, more critically, complete failure when needed most. There’s also a potential for electrical malfunction within the device itself, posing an additional fire hazard.
- Who Might Be Affected: All residents of the apartment complex where these alarms were installed are directly at risk. Additionally, anyone who might have purchased similar devices, particularly from unofficial or disreputable channels, could unknowingly be living with this hazard. First responders, such as firefighters, are also put at greater risk when dealing with fires in buildings where the early warning system integrity is compromised.
- Property Damage Potential: Without functional smoke detection, a small fire can quickly escalate into a catastrophic blaze, resulting in extensive property damage or complete loss of the building.
What Consumers Should Do
If you live in a multi-unit apartment complex or recently had your smoke alarms replaced and suspect they might be counterfeit, take immediate action:
- Immediate Steps: Do not rely on suspicious smoke alarms. If you have any doubt about the authenticity or functionality of your smoke alarms, assume they are defective and replace them immediately with certified devices.
- How to Check for Authenticity:
* Examine the Labeling: Look for spelling mistakes or poor-quality printing on the device or its packaging.
* Verify Certifications: Look for legitimate certification marks from recognized testing laboratories such as UL (Underwriters Laboratories). A real UL mark is typically accompanied by a file number. Merely stating “UL 217” without a clear certification logo or number is a red flag. You can often verify UL certifications on the UL website.
* Purchase Source: Always purchase smoke alarms from reputable retailers or trusted suppliers. Be wary of unusually low prices or sellers who cannot provide documentation of product certification.
- Prevention Measures: Only install smoke alarms that bear the mark of a recognized testing laboratory (e.g., UL, ETL, CSA). Ensure your alarms are interconnected, if possible, so that when one sounds, all sound. Test your smoke alarms monthly and replace batteries at least once a year, or as recommended by the manufacturer.
- Reporting Procedures: If you believe you have a counterfeit smoke alarm, report it immediately to your local fire department. You should also report the incident to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
