Siterwell designs interconnected smoke and carbon monoxide alarms built to meet the performance expectations of modern homes and current US safety codes. Its range of UL-compliant combo alarms is engineered to provide dependable detection while reducing the nuisance alerts that often cause people to disable or ignore their alarms altogether. By designing products to meet both UL 217 and UL 2034 standards, Siterwell focuses on reliable smoke and carbon monoxide protection that performs consistently in everyday conditions.
Many households discover the importance of standards compliance only after problems appear. Combo alarms that sound repeatedly during cooking or environmental changes quickly lose user trust. In many cases, this behavior is linked to devices that do not meet UL requirements, particularly low-cost models sold online without proper certification.
Why UL 217 and UL 2034 Standards Matter
UL 217 governs smoke alarm performance, verifying that an alarm responds effectively to both fast-flaming and slow-smoldering fires while filtering out common nuisance sources like cooking smoke. UL 2034 defines how carbon monoxide alarms must behave at dangerous CO levels and how reliably they function under heat, humidity, and cold.
Together, these standards form the basis of dependable smoke and carbon monoxide protection. In the United States, building and fire codes such as the International Residential Code (IRC R314) expect combination alarms to comply with both UL 217 and UL 2034. Devices that do not meet these requirements may be rejected during inspections in new builds, renovations, or rental properties, and can complicate insurance reviews following an incident.
