As fire safety standards continue to evolve and tighten, Siterwell has met the challenge head-on. The company’s A8612B series combination smoke and carbon monoxide(CO) alarms have successfully completed the rigorous testings required by UL 217 9th Edition (U.S.) and CAN/ULC S531:2019 (Canada), earning Intertek’s ETL certification as a result. This achievement marks a key milestone in Siterwell’s ongoing commitment to product excellence and reinforces its position as a trusted provider in North American markets.
False alarms have long posed a challenge for households across North America—particularly in kitchens, where conventional detectors often fail to distinguish between everyday cooking smoke and real fire hazards. UL 217 9th Edition was specifically designed to address this issue, with a strong emphasis on enhancing smoke detection accuracy. The standard introduces more demanding performance tests, including scenarios like hamburger cooking, where alarms must accurately ignore harmless smoke while remaining responsive to real threats.
To meet the rigorous demands of UL 217 9th Edition, Siterwell formed a dedicated R&D team to drive targeted product enhancements. The team has worked to refine smoke recognition algorithms, calibrate sensor sensitivity, and strengthen structural design against environmental interference. But for Siterwell, certification was never the finish line. It was only a strategic step in the pursuit of real-world safety. Every improvement was guided by clear goals: to deliver faster responses, reduce false alarms, and earn users’ trust.
The A8612B series—including models A8612B-4, A8612B-4R, and A8612B-6AR—is available in standalone, hardwired, and wireless interconnect versions. Each detector integrates high-precision detection, a 10-year battery, bilingual voice alerts, and advanced nuisance alarm reduction into a single solution. With a 360° smoke capturing design and advanced photoelectric sensor, the alarms detect smoke particles at the earliest stages of a fire to ensure rapid response. Dual-wavelength optical technology further enhances accuracy by distinguishing real fire threats from non-hazardous smoke, such as that generated during everyday cooking—significantly reducing nuisance alarms and providing a safer, more reliable user experience.
Achieving UL 217 9th edition certification for the A8612B series is a testament to Siterwell’s leadership in smoke detection technology. For users, it offers the assurance of a dependable, trustworthy safety device—ready to protect when it matters most.
