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

The WisuAlarm DHI-HY-SA40A Battery Smoke Alarm 5 Pack provides dependable, long-term fire protection with five standalone smoke alarms powered by sealed 10-year lithium batteries.

Ideal for larger homes, rental properties or multi-room installations, this five pack allows coverage across hallways, landings, living areas and bedrooms to ensure early warning throughout the property.

Using advanced split-spectrum photoelectric sensor technology, each alarm responds quickly to genuine smoke while reducing common nuisance alarms caused by cooking fumes or steam.

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

A combined test and hush button enables easy manual testing and temporary silencing during false alarms.

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