WisuAlarm Battery Smoke Alarm (10 Year Lithium Battery)

The WisuAlarm DHI-HY-SA40A is a self-contained, battery powered smoke alarm developed to provide dependable early fire detection within domestic properties.

It incorporates split-spectrum photoelectric sensing technology, enabling fast response to both smouldering and fast-flaming fires while helping to limit nuisance alarms caused by steam or normal household activity.

This makes it suitable for installation in bedrooms, lounges, hallways and other primary living areas.

When smoke reaches the activation threshold, the unit emits an 85 dB audible warning supported by a clear visual LED indicator, ensuring occupants are alerted promptly.

A combined test and hush button allows straightforward weekly testing and temporary silencing if required.

For additional convenience, the alarm can also be muted using a standard infrared TV remote, reducing the need for ladders when managing nuisance activations.

The device is powered by a sealed 10-year lithium battery, removing the requirement for mains wiring and supporting low-maintenance, long-term protection.

Its standalone design makes it appropriate for homeowners, landlords and retrofit applications where a simple, compliant smoke alarm solution is required.
