The WisuAlarm Wireless Interlinked Battery Smoke Alarm is powered by a sealed 10-year lithium battery and provides reliable, long-term protection without the need for wiring.
It wirelessly interlinks with up to 24 WisuAlarm devices, ensuring a loud 85 dB alarm sounds throughout the property when smoke is detected.
Using advanced split-spectrum sensor technology, the alarm responds quickly to real fires while significantly reducing false alarms.
This makes it well suited to domestic homes, holiday lets and rental properties, where nuisance alarms from cooking or shower steam can be a common issue.
When one alarm activates, all interlinked units sound together, ensuring occupants are alerted no matter where they are in the property.
The alarm includes a combined test-and-hush button and an audible low-battery warning for added peace of mind.
A unique remote hush feature allows the alarm to be silenced using any standard infrared TV remote.
This makes it easy to mute the alarm during testing or false alarms without the need for ladders.
For additional convenience, the alarm can be paired with an optional Internet Gateway to provide instant notifications via the free mobile app.
This allows you to monitor alarms remotely and stay informed even when you are away from the property.
