Overview Features Technical Data FAQs Downloads & Resources

The WisuAlarm Battery Standalone Smoke Alarm (DHI-HY-SA20A) combines advanced detection technology with contemporary design, offering a reliable and attractive safety solution for domestic settings.

Whether you're upgrading fire protection in a family home, apartment, or small office, this unit delivers high performance with minimal maintenance.

At its core is split-spectrum sensor technology, designed to quickly detect a range of fire types while reducing nuisance alarms from cooking or steam.

Once smoke is detected above a safe threshold, the alarm emits a loud 85dB(A) sound to alert occupants immediately.

10-year lithium battery – no wiring or replacements required
Split-spectrum sensor – fast and accurate smoke detection with fewer false alarms
Integrated 85dB(A) sounder – alerts you clearly and instantly
Test and hush functions combined in a single button
Low battery warning signal for added reassurance
Quick and simple surface installation
Remote hush function – ideal for alarms mounted on high ceilings or stairwells

The unit is powered by a 10-year lithium battery, meaning no need for replacements or mains wiring, making it perfect for landlords, homeowners, or anyone seeking dependable fire safety without ongoing upkeep.

One of its most convenient features is the remote silence capability. In properties with high or hard-to-reach ceilings, pressing a traditional hush button can be impractical or unsafe.

With WisuAlarm, you can silence the alarm using any standard infrared TV remote, making it far easier to manage minor false alarms without needing a ladder.

The built-in sounder emits a loud 85dB(A) alarm at a distance of 3 meters—loud enough to alert occupants even through closed doors.
