WisuAlarm Battery Smoke Alarm 5 Pack (10 Year Lithium Battery)

The WisuAlarm DHI-HY-SA40A Battery Smoke Alarm 5 Pack provides multi-room fire detection using five standalone smoke alarms powered by sealed 10-year lithium batteries.

This configuration is suited to larger homes, HMOs and rental properties where coverage is required across several circulation areas and living spaces.

The five-pack format allows installation in hallways, landings, lounges and bedrooms to support early warning throughout the property.

Each alarm uses split-spectrum photoelectric sensing to deliver rapid response to developing fires while helping to reduce nuisance alarms caused by steam or everyday cooking activity.

When activated, the unit emits an 85 dB audible warning supported by a flashing LED indicator to provide clear confirmation of alarm status.

A combined test and hush button allows straightforward manual testing and temporary silencing where required.

The remote hush function enables the alarm to be silenced using a standard infrared TV remote, which is particularly practical for ceiling-mounted units.

With sealed 10-year lithium batteries and no wiring requirement, this pack offers long-term protection with minimal maintenance obligations.
