Key Features


Cooking nuisance
recognition

PIR motion

85dB @ 3M

EN 14604

UL 217 8th


The SD-32 series, a next-generation multi-functional optical smoke detector compliant with UL 217 8th Edition standards, can distinguishes actual Fire and smoke from daily cooking smoke and steam, minimizing inaccurate alerts. It can also detect Polyurethane foam in fast-moving Fires and slow smoldering burns. Moreover, the SD-32’s patented technology enables it to operate reliably even in environments with substantial dust accumulation, avoiding false alarms. It also sends event codes to notify installers when maintenance is required.

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

Quick Dust Removal

Openable cover allows quick and convenient dust removal

Recognizing different types of fire

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

Interconnection Function

Serial connection enables all connected smoke alarms to sound together when one of them is triggered

Smart Home Automation

PIR motion sensor for home automation lighting control

Lighting for Emergency

Emergency light provides illumination in environment of darkness or dim light
