Resideo R200 battery-powered, networkable smoke alarm

Resideo Smoke Detector R200
Honeywell Home's battery-operated smoke and heat alarms are designed for all types of residential buildings, including holiday homes, guest houses, and caravans.
Due to new regulations within the European Union, the use of fire-resistant household materials, appliances, and furniture in homes is becoming increasingly common. These produce significantly less smoke in the event of a fire than standard materials and are therefore often detected late. Improved safety standards and new regulations, particularly with regard to the installation of smoke alarms, have significantly reduced the consequences of residential fires.
In the event of smoke and heat detection, the smoke and heat alarms warn with a loud 85 dB alarm sound and a flashing red LED.
With wirelessly interconnected alarms, the ONE GO - ALL GO technology triggers the alarm on all other alarms as well, maximizing the alarm effect.
