WisuAlarm Battery Smoke Alarm 3 Pack (10 Year Lithium Battery)

The WisuAlarm DHI-HY-SA40A Battery Smoke Alarm Triple Pack provides reliable, long-term fire protection with three standalone smoke alarms powered by sealed 10-year lithium batteries.

Designed for domestic use, this triple pack is ideal for covering multiple areas within a property, such as hallways, landings, living rooms and bedrooms, helping ensure early warning throughout the home.

Using advanced split-spectrum photoelectric sensor technology, each alarm responds 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 easy 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 ceiling mounted.
