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

The WisuAlarm Battery Smoke Alarm Twin Pack provides reliable, long-term fire protection with two standalone smoke alarms powered by sealed 10-year lithium batteries.

Designed for domestic properties, this twin pack is ideal for installing coverage across multiple areas such as hallways, landings, living rooms or bedrooms, helping ensure early warning throughout the home.

Each alarm uses advanced split-spectrum photoelectric sensor technology, allowing it to respond quickly to real smoke while reducing common false alarms caused by cooking fumes or shower steam.

When smoke is detected, the alarm emits a loud 85 dB audible warning alongside a flashing LED indicator to clearly alert occupants.

A combined test and hush button allows quick manual testing and temporary silencing during nuisance alarms.

For added convenience, the alarm can also be silenced using a standard infrared TV remote, removing the need for ladders when the unit is ceiling mounted.

Powered by a sealed 10-year lithium battery, each alarm requires no wiring and minimal maintenance, making this twin pack suitable for homeowners, landlords and rental properties.
