Smoke Alarm

EN 54 / UL 521 compliance


The SD-32-H is a next-generation smoke and heat detector compliant with UL 217 8th Edition, delivering fast and accurate fire detection. Its dual-LED spectrum optical sensor distinguishes real fire aerosols from everyday cooking smoke and steam, and identifies polyurethane-foam combustion in both fast and slow fires. Patented dust-tolerant technology ensures stable performance in dusty environments and issues pre-alerts when cleaning is required. With dual thermistors for omni-directional heat sensing, and integrated fixed-temperature and rate-of-rise algorithms adhering to EN 54 and UL 521 compliance, the detector supports a broad range of applications while ensuring safety.

Meeting Standards Requirement

Compliant with UL 217 8th edition testing standards

Dust Tolerance

Patented technology enables high tolerance against dust accumulation to prevent false alarms, while sends event codes to notify installers when maintenance is required

Prevention against cooking nuisance and false alarms

Recognize fire and smoke without setting nuisance alarms from cooking

Recognizing different types of fire

Differentiate between fast moving fire and slow smoldering burn, including flaming polyurethane foam

Reliable Heat Detection Employs Multi-Standard Compliance

Heat detection employs multiple mechanisms and standards compliance including EN 54 and UL 521 for wide-ranging applications.
